HTC Carousel Activity/Fragment (Swipeable tabs) - Sense 3.6 up to Sense 6 Samples
HTC Carousel with Tabs for Sense 3.6 up to Sense 4 (Using Activities)
Create classes and Carousel (HTC Sense Tabs)
Create simple activities
Create two classes Tab1.java; Tab2.java
Create two layout xml files - tab_1.xml; tab_2.xml;
Place any two different png icons for Tab1 and Tab2 reference
tab_1.xml
Code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is Tab1" />
</RelativeLayout>
tab_2.xml
Code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is Tab2" />
</RelativeLayout>
Tab1.java
Code:
package com.yourpackage.name;
import android.app.Activity;
import android.os.Bundle;
public class Tab1 extends Activity {
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.tab_1);
}
}
Tab2.java
Code:
package com.yourpackage.name;
import android.app.Activity;
import android.os.Bundle;
public class Tab2 extends Activity {
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.tab_2);
}
}
Create carousel (HTC Sense Tabs) and put tabs together
Create class: TabProvider.java; Remove everything inside class and place this code:
com.yourpackage.name - it is your name of package.
TabProvider.java
Code:
package com.yourpackage.name;
import com.htc.content.CarouselProvider;
[user=1299008]@supp[/user]ressWarnings("deprecation")
public class TabProvider extends CarouselProvider {
final static String AUTHORITY =
"com.yourpackage.name.TabProvider";
public TabProvider() {
super();
setupCarousel(AUTHORITY);
}
}
Open MainActivity, remove everything from class and paste this code:
MainActivity.java
Code:
package com.yourpackage.name;
import android.content.Intent;
import android.os.Bundle;
import com.htc.widget.CarouselActivity;
import com.htc.widget.CarouselHost;
public class MainActivity extends CarouselActivity {
final static String AUTHORITY =
"com.yourpackage.name.TabProvider";
public MainActivity() {
super(AUTHORITY);
}
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setGId(1);
super.onCreate(savedInstanceState);
final CarouselHost mPanelHost = getCarouselHost();
mPanelHost.addTab("Tab1", this, R.string.tab_1,
R.drawable.ic_tab1,
R.drawable.ic_tab1,
R.drawable.ic_tab1,
(new Intent("com.yourpackage.name.Tab1")));
mPanelHost.addTab("Tab2", this, R.string.tab_2,
R.drawable.ic_tab2,
R.drawable.ic_tab2,
R.drawable.ic_tab2,
(new Intent("com.yourpackage.name.Tab2")));
}
}
Configuring manifest
Dont forget, all classes have to be in Manifest.
Code:
<activity
android:name=".Tab1"
android:screenOrientation="portrait"
android:configChanges="orientation"
android:label="Tab1" >
<intent-filter>
<action android:name="com.yourpackage.name.Tab1" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name=".Tab2"
android:screenOrientation="portrait"
android:configChanges="orientation"
android:label="Tab2" >
<intent-filter>
<action android:name="com.yourpackage.name.Tab2" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Also for HTC SDK you have to state Provider: Create provider at the end of Manifest before </application> tag
Code:
<provider
android:name="com.yourpackage.name.TabProvider"
android:authorities="com.yourpackage.name.TabProvider" />
Create ActionBar in HTC Sense Style
For all tabs in your main activity you dont need to create actionbar for each of them, you need only one Actionbar for all Tabs.
That means all Activities which will be part of TabCarousel it will use the same action bar from MainActivity.
Make Changes in your mainactivity as follow:
MainActivity.java with ActionBar
Code:
package com.yourpackage.name;
import android.content.Intent;
import android.os.Bundle;
import com.htc.widget.CarouselActivity;
import com.htc.widget.CarouselHost;
[COLOR="Red"]import com.htc.widget.ActionBarExt;
import com.htc.widget.ActionBarText;[/COLOR]
public class MainActivity extends CarouselActivity {
final static String AUTHORITY =
"com.yourpackage.name.TabProvider";
[COLOR="red"]public static ActionBarText mActionText;[/COLOR]
public MainActivity() {
super(AUTHORITY);
}
[COLOR="red"] private void SetupActionBar()
{
Object obj = new ActionBarExt(this, getActionBar());
((ActionBarExt)obj).setFullScreenEnabled(true);
((ActionBarExt)obj).enableHTCLandscape(false);
mActionText = new ActionBarText(this);
mActionText.setPrimaryText(R.string.app_name);
obj = ((ActionBarExt)obj).getCustomContainer();
((ActionBarContainer)obj).setRightDividerEnabled(true);
((ActionBarContainer)obj).addCenterView(mActionText);
}[/COLOR]
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setGId(1);
super.onCreate(savedInstanceState);
final CarouselHost mPanelHost = getCarouselHost();
[COLOR="red"]SetupActionBar();[/COLOR]
mPanelHost.addTab("Tab1", this, R.string.tab_1,
R.drawable.ic_tab1,
R.drawable.ic_tab1,
R.drawable.ic_tab1,
(new Intent("com.yourpackage.name.Tab1")));
mPanelHost.addTab("Tab2", this, R.string.tab_2,
R.drawable.ic_tab2,
R.drawable.ic_tab2,
R.drawable.ic_tab2,
(new Intent("com.yourpackage.name.Tab2")));
}
}
HTC Carousel with Tabs for Sense 4.1 up to Sense 5.5 (Using Fragments)
Create Carousel Fragment, Tabs, MainActivity
Create Tab Fragments
Now instead of Activities we will use Fragments, and it is difficult for some users. And I will try to explain how to build Carousel and not how to build Fragment Activity. But as example you can refer to my Open Source project myStore (which now converted to Fragments)
Create two classes Tab1Fragment and Tab2Fragment
Tab1Fragment.java
Code:
package your.package.name;
[COLOR="Lime"]#2[/COLOR] import android.app.Fragment;
[COLOR="lime"]#1[/COLOR] public class Tab1Fragment [B][COLOR="red"]extends Fragment[/COLOR][/B] {
Button button;
[COLOR="lime"]#3[/COLOR] public Tab1Fragment () {
}
[COLOR="lime"]#4[/COLOR] [user=439709]@override[/user]
public [B][COLOR="Red"]View onCreateView[/COLOR][/B](LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.tab1, container, false);
[COLOR="Lime"]#7[/COLOR] button = (Button) [B][COLOR="Red"]view.[/COLOR][/B]findViewById(R.id.button);
[COLOR="RoyalBlue"][I]//All your code that you need when application is first time created (see onCreate method example)[/I][/COLOR]
[COLOR="lime"]#5[/COLOR] [B][COLOR="red"]return view;[/COLOR][/B]
}
[COLOR="lime"]#6[/COLOR]
}
As you can see the Class structure is different from what you might get used.
Now you need to extend class as Fragment (#1) and import android.app.Fragment; (#2)
Then you need to have public method which represent the entire Class with the name of the Class (#3)
And Fragment uses onCreateView method instead of onCreate in Activity (#4)
And you also need return statement for the view (#5) which will be at the end after all your code inside onCreateView method
Outside onCreateView you will have all your methods for the purpose of application and those methods you will call from onCreateView method.
Example of (#7) is that how you need to use findViewById method. you need to add view. before the method. Other than tha is the same
Now create Tab2Fragment and use the same method but different layout resources.
Create Tab Provider
Code:
package your.package.name;
import com.htc.fragment.content.CarouselProvider;
public class TabProvider extends CarouselProvider {
public TabProvider(){
super();
setupCarousel(MainActivity.AUTHORITY);
}
}
Create CarouselFragment
Now to store tabs in your application we will use separate Carousel class where you will identify each tab, name, Class, icons , etc
For each tab create method for it for example
Code:
private void addTab1(CarouselHost host, String tag, int icon, int str) {
host.addTab(getActivity(), new CarouselTabSpec(tag,
str, icon, icon, icon, Tab1Fragment.class.getName()));
}
private void addAnotherTab(CarouselHost host, String tag, int icon, int str) {
host.addTab(getActivity(), new CarouselTabSpec(tag,
str, icon, icon, icon, AnotherTabFragment.class.getName()));
}
and in onActivityCreated method add your tab as in example
Code:
addAnotherTab(host, "AnotherTab", R.drawable.another_icon,
R.string.another_tab);
Carousel.java
Code:
package your.package.name;
import android.os.Bundle;
import com.htc.fragment.widget.CarouselFragment;
import com.htc.fragment.widget.CarouselHost;
import com.htc.fragment.widget.CarouselTabSpec;
public class Carousel extends CarouselFragment {
public Carousel() {
super(MainActivity.AUTHORITY);
requestCarouselFeature(CarouselFragment.FEATURE_CUSTOM_TITLE);
}
private void addTab1(CarouselHost host, String tag, int icon, int str) {
host.addTab(getActivity(), new CarouselTabSpec(tag,
str, icon, icon, icon, Tab1Fragment.class.getName()));
}
private void addTab2(CarouselHost host, String tag, int icon, int str) {
host.addTab(getActivity(), new CarouselTabSpec(tag,
str, icon, icon, icon, Tab2Fragment.class.getName()));
}
[user=439709]@override[/user]
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
final CarouselHost host = getCarouselHost();
addTab1(host, "Tab1", R.drawable.ic_tab1,
R.string.tab1);
addTab2(host, "Tab2", R.drawable.ic_tab2,
R.string.tab2);
}
}
Create MainActivity
Now MainActivity will be simple Activity with reference to Carousel class.
Code:
package your.package.name;
public class MainActivity extends Activity {
final static String AUTHORITY = "your.package.name.MainActivity";
private Carousel mCarousel = null;
public void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
final int rootId = 1;
FrameLayout viewRoot = new FrameLayout(this);
viewRoot.setId(rootId);
setContentView(viewRoot);
mCarousel = new Carousel();
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.add(rootId, mCarousel);
ft.commit();
registerForContextMenu(viewRoot);
}
}
Configuration of Manifest
For Fragments you dont need anymore to add permission for them in Manifest (Only for Activities)
So basically with One mainactivity and two Tabs your manifest should look like
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="your.package.name"
android:versionCode="10"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="15"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
allowSkinChange="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="your.package.name.MainActivity"
android:screenOrientation="portrait"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<provider
android:name="your.package.name.TabProvider"
android:authorities="your.package.name.MainActivity" />
</application>
</manifest>
Make sure your provider is exaclty as follow.
HTC Carousel with Tabs for Sense 6 (Using Fragments)
Create CarouselFragment, MainActivity, Tabs
CarouselFragment:
Code:
package com.your.pkg;
[COLOR="red"]import com.htc.fragment.widget.CarouselFragment; <!-- Make sure the imports from com.htc.fragment.*-->
import com.htc.fragment.widget.CarouselHost;
import com.htc.fragment.widget.CarouselTabSpec;[/COLOR]
importcom.your.pkg.MainActivity;
import com.your.pkg.R;
import android.os.Bundle;
public class Carousel extends [COLOR="Red"]CarouselFragment[/COLOR] {
public Carousel() {
super(MainActivity.AUTHORITY);
requestCarouselFeature(CarouselFragment.FEATURE_CUSTOM_TITLE);
}
private void addTab(CarouselHost host, String tag, int icon, int str, String tag5) {
host.addTab(getActivity(), new CarouselTabSpec(tag,
str, tag5));
}
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
final CarouselHost host = getCarouselHost();
addTab(host, [COLOR="Blue"]"FirstTab"[/COLOR], R.drawable.ic_launcher,
R.string.[COLOR="Blue"]first[/COLOR], First.class.getName());
addTab(host, [COLOR="Blue"]"SecondTab"[/COLOR], R.drawable.ic_launcher,
R.string.[COLOR="Blue"]second[/COLOR], Second.class.getName());
[COLOR="Red"]<!-- Add as many addTab(); methods as you need Tabs. The addTab() is universal-->[/COLOR]
}
}
MainActivity
Code:
public class MainActivity extends MfMainActivity {
public final static String AUTHORITY = "mikrosmile.kontrol.MainActivity";
private Carousel mCarousel = null;
static Window window;
@Override
protected void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
super.onCreate(savedInstanceState);
final int rootId = 1;
FrameLayout viewRoot = new FrameLayout(this);
viewRoot.setId(rootId);
setContentView(viewRoot);
mCarousel = new Carousel();
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.add(rootId, mCarousel);
ft.commit();
registerForContextMenu(viewRoot);
getWindow().setFormat(1);
}
}
Tabs
Code:
Any Activity or Fragment
HTC's Release to Refresh method (Swipe2Refresh)
The Release to Refresh is like this:
View attachment 2711413
It can be added to any View. I will show example how to add it to ListView
Code:
[COLOR="red"]import com.htc.widget.OnPullDownListener;[/COLOR]
public static ActionBarRefresh aRefresh;
@Override
protected void onCreate(Bundle bundle) {
//Adding inside onCreate method of you listActivity
list.[COLOR="Red"]setOnPullDownListener(new PullDown());[/COLOR]
}
public class PullDown implements OnPullDownListener{
//just a class inside your listActivity
@Override
public void onGapChanged(int top, int bottom) {
if(top != 0){
actionbarext.getCustomContainer().setRotationMax(top);
actionbarext.getCustomContainer().setRotationProgress(bottom);
//actionbarext.getCustomContainer is your ActionBar container
}
}
@Override
public void onPullDownCancel() {
actionbarext.getCustomContainer().setUpdatingState(0);
}
@Override
public void onPullDownRelease() {
actionbarext.getCustomContainer().setUpdatingState(0);
//do whatever you need to update the list here, you can call a method or AsyncTask from here
}
@Override
public void onPullDownToBoundary() {
actionbarext.getCustomContainer().setRotationProgress(actionbarext.getCustomContainer().getRotationMax());
}
}
Code:
On your method to update list add this to onPreExecute
aRefresh.setVisibility(View.VISIBLE);
aRefresh.setPrimaryText("Updating...");
actionbartext.setPrimaryVisibility(View.GONE);
actionbartext.setSecondaryVisibility(View.GONE);
When you finish your task to update list, inside onPostExecute add this
actionbarext.getCustomContainer().setUpdatingState(0);
Code:
Inside your method to SetupActionBar add this
aRefresh = new ActionBarRefresh(c);
aRefresh.setVisibility(View.GONE);
actionbarext.getCustomContainer().addCenterView(aRefresh);
Add HTC Sense 6 Theme support to your app
Inside your MainActivity add this method
Code:
public static int getHtcThemeID(Context context, int i)
{
return HtcWrapConfiguration.getHtcThemeId(context, i);
}
And in onCreate method add this
Code:
setTheme(getHtcThemeID(context, 0));
This method is returning current Choosen theme ID by Variable from 0 to 3.
So, when you open Personalization - Theme. You see 4 Themes. First 3 has different Color boxes at the top. The first 3 is the actual variable integer from 0 - 3.
So, if you want to get , let's say Red color from Theme 2. You have to Choose Theme 2 in the Theme Settings, and in the app use this:
Code:
setTheme(getHtcThemeID(context, 3));
Once you change Theme, it will also use The Orange color from Theme 1, and the Purple Color from Theme 3
Add SlidingMenu to your Sense application
To make the sliding menu in your application like Mail app or File manager app, follow this:
View attachment 2876504
Code:
public class MainActivity extends [COLOR="Red"]SlidingActivity [/COLOR]{
[COLOR="red"]private SlidingMenu mSlidingMenu;[/COLOR]
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
window = getWindow();
setContentView(R.layout.activity_main);
[COLOR="red"]setBehindContentView(R.layout.activity_behind);
initSlidingMenu();[/COLOR]
SetupActionBar(this);
}
private void initSlidingMenu()
{
mSlidingMenu = getSlidingMenu();
[COLOR="red"]mSlidingMenu.setBehindWidth(500);[/COLOR] [COLOR="Lime"]//any width as you want[/COLOR]
mSlidingMenu.setFadeDegree(0.5F);
mSlidingMenu.setFadeEnabled(true);
mSlidingMenu.setMode(0);
mSlidingMenu.setTouchModeAbove(0);
mSlidingMenu.setOnOpenedListener(new com.htc.widget.SlidingMenu.OnOpenedListener() {
public void onOpened()
{
initSlidingMenuContent();
}
});
}
private void initSlidingMenuContent(){
[COLOR="red"] mSlidingMenu.setShadowWidth(50);
mSlidingMenu.setShadowDrawable(ICservices.getShadowDrawable());[/COLOR][COLOR="Lime"]//any shadow drawable you want
//here is all your code that represent the behind layout. it can be listview or any other View you need[/COLOR]
}
[COLOR="SeaGreen"]//if you want to have a toggle at the actionbar, also add OnClickListener to ActionbarTextView and add IconView to Actionbar[/COLOR]
}
add this permission to Manifest:
[COLOR="red"]<uses-permission android:name="com.htc.permission.APP_DEFAULT" />[/COLOR]
Add 3 Dot menu to actionbar
For the Menu in actionbar you just implement simple menu method, but you dont need to use menu.xml for it.
Also you dont need to create string values for Menu, it will generate automatically for you, the icon, and the name.
This is method to create Menu in ActionBar. Add it in MainActivity before SetupActionBar() method
Code:
public void onCreateContextMenu (ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
menu.add("ContextMenu");
}
[user=439709]@override[/user]
public boolean onCreateOptionsMenu (Menu menu) {
menu.add(1, 1, 1, R.string.settings);
return true;
}
public boolean onOptionsItemSelected(MenuItem menuitem)
{
boolean flag = true;
switch (menuitem.getItemId())
{
case 1:
startActivity(new Intent(this, Settings.class));
break;
}
return flag;
}
This is your new MainActivity with Menu
Code:
package com.yourpackage.name;
import android.content.Intent;
import android.os.Bundle;
import com.htc.widget.CarouselActivity;
import com.htc.widget.CarouselHost;
import com.htc.widget.ActionBarExt;
import com.htc.widget.ActionBarText;
[COLOR="Red"]import android.view.ContextMenu;
import android.view.Menu;
import android.view.MenuItem;[/COLOR]
public class MainActivity extends CarouselActivity {
final static String AUTHORITY =
"com.yourpackage.name.TabProvider";
public static ActionBarText mActionText;
public MainActivity() {
super(AUTHORITY);
}
[COLOR="red"]public void onCreateContextMenu (ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
menu.add("ContextMenu");
}
[user=439709]@override[/user]
public boolean onCreateOptionsMenu (Menu menu) {
menu.add(1, 1, 1, R.string.settings);
return true;
}
public boolean onOptionsItemSelected(MenuItem menuitem)
{
boolean flag = true;
switch (menuitem.getItemId())
{
case 1:
startActivity(new Intent(this, Settings.class));
break;
}
return flag;
}[/COLOR]
private void SetupActionBar()
{
Object obj = new ActionBarExt(this, getActionBar());
((ActionBarExt)obj).setFullScreenEnabled(true);
((ActionBarExt)obj).enableHTCLandscape(false);
mActionText = new ActionBarText(this);
mActionText.setPrimaryText(R.string.app_name);
obj = ((ActionBarExt)obj).getCustomContainer();
((ActionBarContainer)obj).setRightDividerEnabled(true);
((ActionBarContainer)obj).addCenterView(mActionText);
}
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setGId(1);
super.onCreate(savedInstanceState);
final CarouselHost mPanelHost = getCarouselHost();
SetupActionBar();
mPanelHost.addTab("Tab1", this, R.string.tab_1,
R.drawable.ic_tab1,
R.drawable.ic_tab1,
R.drawable.ic_tab1,
(new Intent("com.yourpackage.name.Tab1")));
mPanelHost.addTab("Tab2", this, R.string.tab_2,
R.drawable.ic_tab2,
R.drawable.ic_tab2,
R.drawable.ic_tab2,
(new Intent("com.yourpackage.name.Tab2")));
}
}
HTC AlertDialog
In order to have alertdialog you need to have OnClickListener and inside OnClickListener you paste alertDialog.
Code:
public void onItemClick(HtcAdapterView<?> parent, View view, int position, long id) {
[COLOR="red"]HtcAlertDialog.Builder[/COLOR] alertDialog = new [COLOR="red"]HtcAlertDialog.Builder[/COLOR]([B]YourActivity.this[/B]);
alertDialog.setTitle(R.string.title_txt);
alertDialog.setMessage(R.string.message_txt);
alertDialog.setIcon(R.drawable.icon);
alertDialog.setPositiveButton(R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int which) {
//Do your actions here when user click Yes
}
});
alertDialog.setNegativeButton(R.string.no, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
//Do your action here when user click No.. or just cancel dialog using follow..
dialog.cancel();
}
});
alertDialog.show();
}
As you can see Dialog is not so difficult, but need to identify exaclty which Builder you are gonna use.
YourActivity.this - means the activity where you create the dialog
You can also see available options of what you can implement inside dialog.. like 3 buttons.
Start typing alertDialog. finish with the dot and in Eclipse there will be new pop-up window and you can add some more
Also dont forget alertDialog.show(); at the end, otherwise Dialog wont shows
HTC ListView and HtcListActivity.
There are two ways of implementing Htc List view. You can use Simple Activity, Fragment or just easy use HtcListActivity extension.
For full htc style you need to use Main List layout, and Details layout + List adapter.
Example using Activity
Code:
public class AboutActivity extends Activity {
[COLOR="Red"]HtcListView lv1;[/COLOR]
[user=439709]@override[/user]
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.about_activity);
ArrayList<AboutDetails> image_details = GetSearchResults();
[COLOR="red"]final HtcListView lv1 = (HtcListView) findViewById(R.id.about_list);[/COLOR]
[user=1299008]@supp[/user]ressWarnings("unused")
lv1.setAdapter(new AboutListBaseAdapter(this, image_details));
lv1.setOnItemClickListener(new HtcAdapterView.OnItemClickListener() {
Vibrator vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
[user=439709]@override[/user]
public void onItemClick(HtcAdapterView<?> a, View v, int position, long id) {
vibrator.vibrate(50);
Object o = lv1.getItemAtPosition(position);
final AboutDetails obj_itemDetails = (AboutDetails)o;
}
});
}
private ArrayList<AboutDetails> GetSearchResults(){
ArrayList<AboutDetails> results = new ArrayList<AboutDetails>();
AboutDetails item_details = new AboutDetails();
item_details.setName(R.string.mikrosmile);
item_details.setItemDescription(R.string.mikrosmile_info);
item_details.setImageNumber(1);
results.add(item_details);
return results;
}
}
AboutDetails
Code:
public class AboutDetails {
public int getName() {
return name;
}
public void setName(int name) {
this.name = name;
}
public int getItemDescription() {
return itemDescription;
}
public void setItemDescription(int itemDescription) {
this.itemDescription = itemDescription;
}
public int getImageNumber() {
return imageNumber;
}
public void setImageNumber(int imageNumber) {
this.imageNumber = imageNumber;
}
private int name ;
private int itemDescription;
private int imageNumber;
}
AboutListBaseAdapter
public class AboutListBaseAdapter extends BaseAdapter {
private static ArrayList<AboutDetails> aboutDetailsrrayList;
private Integer[] imgid = {
R.drawable.mikrosmile,
};
private LayoutInflater l_Inflater;
public AboutListBaseAdapter(Context context, ArrayList<AboutDetails> results) {
aboutDetailsrrayList = results;
l_Inflater = LayoutInflater.from(context);
}
public int getCount() {
return aboutDetailsrrayList.size();
}
public Object getItem(int position) {
return aboutDetailsrrayList.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {

HTC ListView Example by xcesco89
Add HTC Sense Skin support.
In AndroidManifest add this line inside <application tag and before first <activity tag where you have your MainActivity
Code:
<application
[COLOR="Red"]allowSkinChange="true"[/COLOR]
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.yourpackage.name.MainActivity"
There will be Error in Manifest, says "Attribute is missing the Android namespace prefix"
It is fine, to fix it go to - Project -> Clean; Choose your Application and click Ok
Add reference library to use full HTC app experience
Sense 6
Download this package - View attachment addon-htc_opensense_apis-htc-19.zip
Place the extracted folder to <location of android SDK>\android\sdk\add-ons\
Choose HTC OpenSense SDK 19 when you start building your application. Profit
Sense 5 and below
Refer to this, thanks to Jonny
Make sure HTCExtension lib is appear in your Eclipse project
Use HTCPreference Activity
Htc Preference is the same as normal Preference but you need to follow some rules when you want to have this.
First in your Preference activity (for example you already have one) change PreferenceActivity to HtcPreferenceActivity.
import com.htc.preference.*;
In prefs.xml (or any other xml file you have your preferences in) make sure everything is using this way
This is original android way.
<PreferenceScreen> </PreferenceScreen>
This is Htc way
<com.htc.preference.HtcPreferenceScreen> </com.htc.preference.HtcPreferenceScreen>
So basically to every single item in preferences you need to add com.htc.preference.Htc****
Here is prefs.xml example
Code:
<?xml version="1.0" encoding="utf-8"?>
<[COLOR="Red"]com.htc.preference.Htc[/COLOR]PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >
<[COLOR="red"]com.htc.preference.Htc[/COLOR]CheckBoxPreference
android:title="@string/load_icons"
android:summary="@string/load_icons_summary"
android:defaultValue="true"
android:key="show_dialog">
</[COLOR="red"]com.htc.preference.Htc[/COLOR]CheckBoxPreference>
<[COLOR="red"]com.htc.preference.Htc[/COLOR]SwitchPreference
android:title="@string/load_skins"
android:summary="@string/load_skins_summary"
android:switchTextOn="@string/on"
android:switchTextOff="@string/off"
android:defaultValue="true"
android:key="skins_on_start">
</[COLOR="red"]com.htc.preference.Htc[/COLOR]SwitchPreference>
</[COLOR="red"]com.htc.preference.Htc[/COLOR]PreferenceScreen>
This is how Pref activity should be
Code:
package com.yourpackage.name;
import android.os.Bundle;
import android.view.View;
import com.htc.widget.ActionBarContainer;
import com.htc.widget.ActionBarExt;
import com.htc.widget.ActionBarText;
[COLOR="red"]import com.htc.preference.*;[/COLOR]
public class Settings extends [COLOR="red"]Htc[/COLOR]PreferenceActivity {
private ActionBarExt actionBarExt=null;
private ActionBarText actionBarText=null;
private ActionBarContainer actionBarContainer=null;
private void SetupActionBar() {
actionBarExt=new ActionBarExt(this,getActionBar());
actionBarExt.enableHTCLandscape(false);
actionBarContainer=actionBarExt.getCustomContainer();
actionBarText=new ActionBarText(this);
actionBarText.setPrimaryText(R.string.settings);
actionBarContainer.addCenterView(actionBarText);
actionBarContainer.setRightDividerEnabled(true);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.prefs);
}
SetupActionBar();
}
}
If you cannot import com.htc.preference.*; (Eclipse will give you error) it means you dont have HtcExtension lib. Make sure you added it before doing this.
Great guide! HTC Dialog isn't hard, just the same as the normal dialog, but putting Htc before the dialog stuff, right?
Looking forward to the ListView guide!

This is not image actually, it is skin support..
I was planning to write about it later ))
OK in manifest after <application tag add this line
allowSkinChange="true"
You will have error. Go to Project and perform a Clean . try and report back

Weird.. Cannot edit ..
So this line should be in the same pack where you have android icon and theme info before the first activity tag

add an HtcListView it's quite simple!
this works exactly as the android ListView
a simple example:
(as base i've used TabPlus4Demo a sample project in OpenSense SDK samples )
main.xml
HTML:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<com.htc.widget.HtcListView
android:id="@+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
(Note that you need to use com.htc.widget.HtcListView instead of ListView )
the code:
Code:
public class SimpleTab extends Fragment {
public HtcListView lv;
[user=439709]@override[/user]
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
if(getArguments() != null) {
int resId = getArguments().getInt("LAYOUT");
if(resId != 0)
return inflater.inflate(resId, null);
}
ViewGroup rootView = (ViewGroup) inflater.inflate(
R.layout.main, container, false);
[B]//Find the view[/B]
lv = (HtcListView) rootView.findViewById(R.id.listView1);
[B]//create the list[/B]
List<String> list = new ArrayList<String>();
[B]//add some list Items ( if you want a custom text , just use list.add("blahblah")[/B]
for (int i =0; i<40; i++) {
list.add("Test"+i);
}
[B]//create the adapter[/B]
ArrayAdapter<?> adapter = new ArrayAdapter<String>(this.getActivity(),
android.R.layout.simple_list_item_1, list);
[B]//Set the adapter[/B]
lv.setAdapter(adapter);
[B]/*
create and set the Listener
you can also implement this in your activity with
"public class youractivity extends Activity implements OnItemClickListener"
then use lv.setOnItemClickListener(this)
*/[/B]
lv.setOnItemClickListener(new OnItemClickListener() {
[user=439709]@override[/user]
public void onItemClick(HtcAdapterView<?> arg0, View v,
int pos, long id) {
[B]//make a Toast Message that displays the Selected item NAME[/B]
Toast.makeText(v.getContext(),"pressed: "+ lv.getItemAtPosition(pos), Toast.LENGTH_SHORT).show();
[B]/*
if you want t perform something different for each item you can use the case statement
switch(pos){
case 0:
Toast.makeText(v.getContext(), "HI!", Toast.LENGTH_SHORT).show();
break;
case 1:
Toast.makeText(v.getContext(), "HELLO!", Toast.LENGTH_SHORT).show();
break;
[...]
case 39:
//do something
break;
*/[/B]
}
});
return rootView;
}
}

this is not part of OpenSense SDK.. they wont open it. You need to create own framework..
this is actually part of HtcPreferenceActivity which you cant create in Eclipse without proper libs..
Other than that you can create similar png.9 image and make it looks like )

I am having trouble creating a webview app for my already mobile ready site.
I keep getting this error in the emulator:
The application window cleaning forums (process com.windowcleaningforums) has stopped unexpectadly
The app never actualy loads just goes straight to this.
Basically i already have my sites mobile ready and browsing to them on your mobile works fine, but would like to put these into apps.
With a back, forward and refresh button when hitting menu button on phone.
(I am not sure what i need to add these yet but any advice would be great)
My project is set as bellow
Application name: Window Cleaning Forums
Package name: com.windowcleaningforums
Create activity: windowcleaningforums
Mini SDK version: 4
windowcleaningforums.java
Code:
package com.windowcleaningforums;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class windowcleaningforums extends Activity {
/** Called when the activity is first created. */
//@Override
private class HelloWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
@Override

if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
WebView mWebView;
public void onCreate(Bundle savedInstanceState) {

setContentView(R.layout.main);
mWebView = (WebView) findViewById(R.id.webView);

mWebView.setWebViewClient(new HelloWebViewClient());
}

I am very new and im not quite sure what is causing it any help would be great. Thanks
I get this if that is any help i am not sure what it means though.
[2011-01-12 22:35:07 - DeviceMonitor]Sending jdwp tracking request failed!
This is the log if that helps also i really could do with some help peeps, nobody seems to want to. I know i am new and prob asking stupid questions but how am i supposed to learn if i dont ask questions.
Hi cyberpedz,
Probably just a typo but in your main.xml the WebView tag should have a capital "W" like so:
<WebView xmlns:andro...
You did the right thing looking in the log. That's what helped to figure this one out: there was an exception stack trace in the log. (Keep an eye out for the "AndroidRuntime" tag)
Thanks i have changed that but no difference.
I do have a red dot over a hellowebview class though
When viewing windowcleaningforums.java and looking at the right in outline i have a read dot over hellowebviewclient
Could it be something to do with this bit of code?
Code:
public class windowcleaningforums extends Activity {
/** Called when the activity is first created. */
//@Override
private class HelloWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
Try moving the
Code:
//@Override
just before onCreate and uncomment it.
Also Java classes should start with a capital (public class Windowcleaningforum). Make sure you modify the Manifest accordingly.
Ok finally i have it working, it was me being blind i missed a webView now changed to Webview and all works thanks so much.
Now i am trying to get a loading progress bar or even better spinning circle.
What code would i need for this and where abouts in my java bellow would i fit it in?
Code:
package com.windowcleaningforums;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class windowcleaningforums extends Activity {
/** Called when the activity is first created. */
//@Override
private class HelloWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
WebView mWebView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mWebView = (WebView) findViewById(R.id.WebView);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("http://www.windowcleaningforums.co.uk");
mWebView.setWebViewClient(new HelloWebViewClient());
}
}
Anyone know how to get the spinning circle while pages loads? and how to imput into my code above?
Would be a great help
Ok finally i have a running webview in the market what i would like to do now is add a soft menu for a back, refresh and forward button what code do i need and where would i put it in my java below?
Code:
package com.windowcleaningforums;
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class windowcleaningforums extends Activity
{
final Activity activity = this;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.main);
WebView webView = (WebView) findViewById(R.id.WebView);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress)
{
activity.setTitle(" Loading...");
activity.setProgress(progress * 100);
if(progress == 100)
activity.setTitle(R.string.app_name);
}
});
webView.setWebViewClient(new WebViewClient() {
@Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
{
// Handle the error
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
});
webView.loadUrl("http://www.windowcleaningforums.co.uk");
}
}
So why is it no body wants to help is it the way i ask? is it that developers think they are above the noob? or you really cant b bothered!!
I have even offered to pay for help in the past yet nobody is interested maybe it is that no one really knows the answers.

It's not that developers can't be bothered, but generally they will have other things to do than help out others. The thing is, you're asking on help for pretty basic stuff. This is something that you should know already, and if don't I suggest you should read through Android's developer website one more time and look at the API examples/demos too.
Hints for your problem; Add the buttons as a merge layout in your XML and then link them with your web view, or add them as menu options. Googling for both will surely give you enough results to get you on your way, these are pretty basic things you want to do after all.
Doing a theme for ADW and want to include a wallpaper chooser so the user can browse through my wallpaper set...
I am working in eclipse.
I have successfully got setup in wallpaper menu (when you press and hold homescreen, select wallpaper, Then you see the option for wallpaper i have setup)
BUT when click i get a force close...
I have 10 wallpapers in my drawable-hdpi folder. they are named
wallpaper1
wallapper2
etc...
I also have my wallpaper1_small, etc... set up too..
This is contents of my wallpaper_chooser.xml in layout
Code:
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<ImageView android:id="@id/wallpaper" android:layout_width="fill_parent" android:layout_height="0.0dip" android:scaleType="fitCenter" android:layout_weight="1.0" />
<Gallery android:id="@id/gallery" android:layout_width="fill_parent" android:layout_height="wrap_content" />
<Button android:layout_gravity="center_horizontal" android:id="@id/set" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Set wallpaper" />
</LinearLayout>
This is my wallpaper_item.xml in layout
Code:
<?xml version="1.0" encoding="UTF-8"?>
<ImageView android:background="?android:galleryItemBackground" android:focusable="true" android:layout_width="wrap_content" android:layout_height="wrap_content" android:scaleType="fitXY"
xmlns:android="http://schemas.android.com/apk/res/android" />
this is my arrays.xml in values-hdpi folder
Code:
<?xml version="1.0" encoding="UTF-8"?>
<resources>
<string-array name="wallpapers">
<item>wallpaper1</item>
<item>wallpaper2</item>
<item>wallpaper3</item>
<item>wallpaper4</item>
<item>wallpaper5</item>
<item>wallpaper6</item>
<item>wallpaper7</item>
<item>wallpaper8</item>

It goes into the wallpaper picker without getting FC but after sliding the wallpapers on bottom it goes away all of a sudden...
One note is that the following code was originally R.layout.wallpaper, BUT get error...
changed to (setContentView(R.layout.wallpaper_chooser)
Is this that difficult?
or just not that common?
or maybe i should be more familiar with how apk's work?
Any help is appreciated...

Hello everyone,
As most of you probably have, I have been working on an app that lets users input text in an EditText. However, this app possibly gets a lot of input from the user, which can lead to multiple lines of text in either of two EditTexts!
Naturally, this can result in some real headaches: when you want to clear the EditText, you'll have to delete character after character from it.
So, I decided to go on a quest. Hunt down a solution that's fat, easy to implement and works nicely from the user's prespective. Of course, it'd be nice if it looks cool, too.
This is where I came across a blog post, after some browsing of StackOverflow, that detailed a nice and quick fix.
Today, I will be explaining to all of you how to implement this, and even add a couple of little extras.
Step 1: Creating the custom View's XML layout
The first thing you have to do, since this is a custom View, is create its XML layout. Luckily, this isn't too hard:
Code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<EditText
android:id="@+id/clearable_edit"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingRight="35dip" />
<Button
android:id="@+id/clearable_button_clear"
android:layout_width="30dip"
android:layout_height="30dip"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="5dip"
android:background="@drawable/ic_clear" />
</RelativeLayout>
Some explanation: This is just a layout declaration. Later on, when making the ClearableEditText constructor, you'll have to call upon the elements in this layout.
Step 2: Making the class
To create an own new View, you have to extend from one of the standard View classes. Since you are including a Button and EditText in the one (creating a compound View), RelativeLayout is a good choice.
In the constructors of the class - which overrides the stock EditText constructors - is where you inflate the layout, which has been done by adding a method initViews().
The method to pay attention to here is showHideClearButton. An addTextChangedListener call is made, which conveniently takes a TextWatcher as its parameter. That means we can easily see when something about the input changes, and act upon it.
Some methods have to be implemented, but onTextChanged is the only one we'll really need. Here, we can check the length of the String that's been entered, and see whether to hide or show to cross Button for clearing the EditText.
The code speaks for itself from here on out:
Code:
import android.content.Context;
import android.text.Editable;
import android.text.TextWatcher;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.RelativeLayout;
public class ClearableEditText extends RelativeLayout {
LayoutInflater inflater = null;
EditText edit_text;
Button btn_clear;
public ClearableEditText(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
initViews();
}
public ClearableEditText(Context context, AttributeSet attrs) {
super(context, attrs);
initViews();
}
public ClearableEditText(Context context) {
super(context);
initViews();
}
void initViews() {
inflater = (LayoutInflater) getContext().getSystemService(
Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.clearable_edit_text, this, true);
edit_text = (EditText) findViewById(R.id.clearable_edit);
btn_clear = (Button) findViewById(R.id.clearable_button_clear);
btn_clear.setVisibility(RelativeLayout.INVISIBLE);
clearText();
showHideClearButton();
}
void clearText() {
btn_clear.setOnClickListener(new OnClickListener() {
[user=439709]@override[/user]
public void onClick(View v) {
edit_text.setText("");
}
});
}
void showHideClearButton() {
edit_text.addTextChangedListener(new TextWatcher() {
[user=439709]@override[/user]
public void onTextChanged(CharSequence s, int start, int before,
int count) {
if (s.length() > 0)
btn_clear.setVisibility(RelativeLayout.VISIBLE);
else
btn_clear.setVisibility(RelativeLayout.INVISIBLE);
}
[user=439709]@override[/user]
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
[user=439709]@override[/user]
public void afterTextChanged(Editable s) {
}
});
}
public Editable getText() {
Editable text = edit_text.getText();
return text;
}
}
Step 3: Using the ClearableEditText
So now, we have a (hopefully) fully functional implementation. We are still missing something, though! Of course, we haven't implemented our own solution into the code yet.
Luckily, this is very easy and takes mere seconds.
To use your ClearableEditText in a layout, simply add its full path to one of the elements, like so:
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<[packagename].ClearableEditText
android:id=”@+id/edit_text_clearable”
android:layout_width=”fill_parent”
android:layout_height=”wrap_content” />
</LinearLayout>
See? Very easy. There is still one minor issue, though...
Step 4: Finishing touches - setting attributes
As you have probably eagerly tried, the above code should completely work and give you a working clearable EditText.
Of course, since there's no free lunch in computer science, there's a catch: no attributes can be set from your layout's XML file (the number of lines, text size, etc.).
So, I thought up a very simple way of doing this programatically, from your Java code. These supplements does take extra lines in your class' code, but will do exactly the same as their XML counterparts.
In your ClearableEditText class, to set the input type, hint and maximum number of lines, add:
Code:
public void setHint(int encode) {
edit_text.setHint(encode);
}
public void setMaxLines(int lines) {
edit_text.setMaxLines(lines);
}
public void setType(int type) {
edit_text.setInputType(type);
}
Then, in your main class, where you're calling those methods:
Code:
<editTextName>.setHint("Hello world!");
<editTextName>.setMaxLines(5);
<editTextName>.setType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_SIGNED);
Keep in mind these are examples. The setType call will set the ClearableEditText to only receive numbers, which can be positive and negative (signed, after the sign bit in bit notation). I recommend you look up the API entry for it, or Google for it.
This can be done for - seemingly, mind - any type of attribute. I've used this for text size, number of lines, to get the text, and the above examples.
Should you have anymore questions or things to say about this, please do so!
Have fun,

I am trying to get a value that user enters into a Dialog, using the recommended DialogFragment class for it, the Dialog constructs and runs fine, but I cannot return the value of the EditText parameter to the parent class, without get a Null pointer exception.
My DialogHost class, this constructs, returns and links the parent to its buttons.
Code:
package jo.app.co;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.app.DialogFragment;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.LayoutInflater;
public class DialogHost extends DialogFragment {
public interface NoticeDialogListener {
public void onDialogPositiveClick(DialogFragment dialog);
public void onDialogNegativeClick(DialogFragment dialog);
}
NoticeDialogListener mListener;
[user=439709]@override[/user]
public void onAttach(Activity activity) {
super.onAttach(activity);
try {
mListener = (NoticeDialogListener) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString());
}
}
[user=439709]@override[/user]
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
builder.setView(inflater.inflate(R.layout.dialog_add, null))
.setPositiveButton("Save", new DialogInterface.OnClickListener() {
[user=439709]@override[/user]
public void onClick(DialogInterface dialog, int id) {
mListener.onDialogPositiveClick(DialogHost.this);
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
DialogHost.this.getDialog().cancel();
}
});
return builder.create();
}
}
My MainActivity
Code:
package jo.app.co;
import android.app.DialogFragment;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.util.Log;
import android.widget.EditText;
public class MainActivity extends FragmentActivity implements DialogHost.NoticeDialogListener {
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
showNoticeDialog();
}
public void showNoticeDialog() {
DialogFragment dialog = new DialogHost();
dialog.show(getFragmentManager(), "DialogHost");
}
[user=439709]@override[/user]
public void onDialogPositiveClick(DialogFragment dialog) {
EditText myText = (EditText) findViewById(R.id.item_added);
try {
Log.d ("IN TRY", myText.getText().toString());
}
catch (Exception e) {
Log.e ("IN CATCH", e.toString());
}
}
[user=439709]@override[/user]
public void onDialogNegativeClick(DialogFragment dialog) {
Log.d ("INMAIN", "REACHED NEG");
}
}
This is my layout for the add item dialog.
Code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<EditText
android:id="@+id/item_added"
android:inputType="text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:layout_marginLeft="4dp"
android:layout_marginRight="4dp"
android:layout_marginBottom="4dp"
android:hint="@string/hint_add_item" />
</LinearLayout>
It's because in your main activity you are trying to call findViewById:

This is not possible since the layout of the activity is not the one the dialog is using. There are multiple ways of doing this, for instance call findViewById in the dialog's onPositiveButtonListener and pass that value through your interface. It might be that you need to use the LayoutInflator in the onCreateDialog, set
LinearLayout linearl = (LinearLayout) inflater.inflate(...) and get the EditText from there. You then call setView(linearL) instead.

I tried calling findViewById method in the onClick method in the Dialog class, but the function is not defined for a DialogInterface.onClickListner, I modified it to linearl method you told but I cannot get it to work either.
Could you make the changes in the 2 snippets above, it would be very helpful!
You'll have to setup listeners fo this and pass the string or whetever you want to pass to back to the activity which in its turn can handle it (do it by itself or pass this to another fragement).
Although not so much votes (0) the last answer here on stackoverflow has exeactly what you need.
Hi there
I am new to this forum as an User, and I am also new to Java and Android, in developing ways. Sorry if there are any language or other mistakes.
So I am trying to make an app for a 'final' school project, which has the follow use:
The user sees an picture, a 'next' (and a 'finish') button. there are 11 pictures (user only sees one)(in the code there are for testing purposes only 3) when the user clicks 'next', the pic no. 2 appears, if he clicks another time next, the pictuer no. 3 appears and so on. (If he clicks finish, he should see a messages which shows him the text: "you've made it until pic xy" but i'm not so far yet.) I tried to do it with this code, but i failed.
Code:
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.Toast;
public class VisusActivity extends Activity implements OnClickListener {
ImageView testanzeige;
Button next;
Integer[] bildanzeige = {
R.drawable.visustest,
R.drawable.v2,
R.drawable.v3
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_visus);
testanzeige = (ImageView)findViewById(R.id.testanzeige);
next = (Button)findViewById(R.id.next);
next.setOnClickListener(this);
next.setOnClickListener(this);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.visus, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
public void onClick(View v) {
try {
//Toast.makeText(this, getResources().getDisplayMetrics().toString(), Toast.LENGTH_LONG).show();
testanzeige.setImageResource(bildanzeige[0]);
}catch(Exception e){
Toast.makeText(this, e.toString(), Toast.LENGTH_LONG).show();
}
};
public void onClick1(View v) {
try {
//Toast.makeText(this, getResources().getDisplayMetrics().toString(), Toast.LENGTH_LONG).show();
testanzeige.setImageResource(bildanzeige[2]);
}catch(Exception e){
Toast.makeText(this, e.toString(), Toast.LENGTH_LONG).show();
}
}
}
so what have I to do? no tutorial shows up exactly my problem ( I think it's such a basic thing everyone can do it^^)

In Your Java You can use Button.setOnClickLiestner(new View.OnClickLiestner It will bit easier than it because When We Implement Anything in Your Class we need delcare methods @override somethings you can use int to change Image
In My Java I have int values that will change every click on Button according to values it will change imageview you have write java that is tough from Me you can use my one it will bit easier Ok
Thank you new problem
Thank you so very much AndroidFire withoup you i've wouldn't made it this far. So you say I can use your code (with your name in it) in my Project?

Now while this problem is solved another problem has come up.
As I told you in my first thread, there is a finish button. It has this use:
when user clicks next 2 times (so if he made it until the 3rd picture) and then clicks finish, he'll Return to the main activity, and instead of the text 'Klicke auf start um zu beginnen' (click on start to begin) the text 'you made it until the 3rd picture' should show up.
If he clicked Next 5 times (6th picture) and clicks finish, he also returns to the main activity, but the text is 'you made it until the 5th picture'.
And so on with the others.
now i dont know, how to implement multiple buttons, how can I learn that? also how did you learn to code, AndroidFire? It's such a masterpiece *-*
I've tried this, but I failed.
the red lines are those, which I made at my own but they unfortunately don't work

<string name="Text1">Klicke auf Start um zu beginnen.</string>
<string name="cantread">finish</string>
Thank you so much
other way also not work
Well I have tried another solution, but it didn't work either. What do I have to do?
Code:
Code:
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.Toast;
/**

*/
public class VisusActivity extends Activity {
Button next;
ImageView testanzeige;
Button finish;
int i = 0;
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_visus);
next = (Button)findViewById(R.id.next);
testanzeige = (ImageView)findViewById(R.id.testanzeige);
finish = (Button)findViewById(R.id.finish);
next.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View arg0) {
i++;
// To Set Your 1 Image Do it Thorough Layout
if (i == 1 ) {
//Your 2 Image
testanzeige.setImageResource(R.drawable.visustest);
}
else if (i == 2) {
//Your 3 Image
testanzeige.setImageResource(R.drawable.v2);
}
else if (i == 3) {
//Your 4 Image
testanzeige.setImageResource(R.drawable.v3);
}
else if (i == 4) {
// Your 5 Image
//Imagey.setImageResource(R.drawable.Your Image);
}
else if (i == 5 ) {
//Your 6 Image
//Imagey.setImageResource(R.drawable.Your Image);
}
else if (i == 6) {
//Your 7 Image
//Imagey.setImageResource(R.drawable.Your Image);
}
else if (i == 7 ) {
//Your 8 Image
//Imagey.setImageResource(R.drawable.Your Image);
}
else if (i == 8 ) {
//Your 9 Image
//Imagey.setImageResource(R.drawable.Your Image);
}
else if (i == 9) {
//Your 10 Image
testanzeige.setImageResource(R.drawable.visustest);
}
else if (i == 10) {
//Image 11 Image
next.setText("Finish");
Toast.makeText(getApplicationContext(), "Your Final Text", Toast.LENGTH_LONG).show();
}
}
});
[COLOR="Red"]finish.setOnClickListener(new View.OnClickListener() {
Intent i = new Intent(this, MainActivity.class);
[user=439709]@override[/user]
public void onClick(View arg0) {
i++;
if (i == 1 ) {
String content = "You got 0.1".toString();
i.putExtra("0.1", content);
[/COLOR]
}
}
}
}
I'm assuming you declared your activity in the Manifest?

Click to expand...
Click to collapse
uhm I think so.
Edit: there are 2 activity-groups in my manifest, so I think they've been declared automatically?
After looking at your code further, you are using onClick methods but aren't implenting an onClickListener. Are your buttons working at all?
yes, they are working fine. I just dont know how to change the text.

There are two ways I can think of to solve this one.
The first is to create an Application class, declare that in the manifest, and add a variable in there to save how many images have been seen. Just set it in the one activity and in the other read it, and if it's 0, show the start message, and if it's greater than 0 show the message you want.
The cooler way is to use startActivityForResult to go to the picture viewing activity. The picture viewing activity keeps track of how many the user saw and then, when they leave:
Code:
Intent returnData = new Intent();
returnData.putExtra("PICTURES_SEEN", count);
setResult(RESULT_OK, returnData);
Then, in the first activity:
Code:
@Override
protected void onActivityResult (int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
int picturesSeen = data.getExtra("PICTURES_SEEN");
// do stuff
}
}
Hopefully that's helpful.
(There's a page in Google's API called "Getting a Result from an Activity" but I can't link to it because I'm a spammernew.)
