[Q] Can anybody help me!!??

Hello XDA users! I'm trying to develop an Android Launcher. First I want to "call" all apps in a Grid View. All works great, but appears a List View and I want a Grid. This is my code, where is the problem?
MainActivity.java
Code:
public class MainActivity extends Activity {
private GridView mGrid;
[user=439709]@override[/user]
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// set layout for the main screen
setContentView(R.layout.layout_main);
// load list application
mGrid = (GridView)findViewById(R.id.lvApps);
// create new adapter
AppInfoAdapter adapter = new AppInfoAdapter(this, Utilities.getInstalledApplication(this), getPackageManager());
// set adapter to list view
mGrid.setAdapter(adapter);
// implement event when an item on list view is selected
mGrid.setOnItemClickListener(new OnItemClickListener() {
[user=439709]@override[/user]
public void onItemClick(AdapterView parent, View view, int pos, long id) {
// get the list adapter
AppInfoAdapter appInfoAdapter = (AppInfoAdapter)parent.getAdapter();
// get selected item on the list
ApplicationInfo appInfo = (ApplicationInfo)appInfoAdapter.getItem(pos);
// launch the selected application
Utilities.launchApp(parent.getContext(), getPackageManager(), appInfo.packageName);
}
});
}
}
AppInfo.java
Code:
public class AppInfoAdapter extends BaseAdapter {
private Context mContext;
private List mListAppInfo;
private PackageManager mPackManager;
public AppInfoAdapter(Context c, List list, PackageManager pm) {
mContext = c;
mListAppInfo = list;
mPackManager = pm;
}
[user=439709]@override[/user]
public int getCount() {
return mListAppInfo.size();
}
[user=439709]@override[/user]
public Object getItem(int position) {
return mListAppInfo.get(position);
}
[user=439709]@override[/user]
public long getItemId(int position) {
return position;
}
[user=439709]@override[/user]
public View getView(int position, View convertView, ViewGroup parent) {
// get the selected entry
ApplicationInfo entry = (ApplicationInfo) mListAppInfo.get(position);
// reference to convertView
View v = convertView;
// inflate new layout if null
if(v == null) {
LayoutInflater inflater = LayoutInflater.from(mContext);
v = inflater.inflate(R.layout.layout_appinfo, null);
}
// load controls from layout resources
ImageView ivAppIcon = (ImageView)v.findViewById(R.id.ivIcon);
TextView tvAppName = (TextView)v.findViewById(R.id.tvName);
// set data to display
ivAppIcon.setImageDrawable(entry.loadIcon(mPackManager));
tvAppName.setText(entry.loadLabel(mPackManager));
// return view
return v;
}
}
Utilities.java
Code:
public class Utilities {
/*
* Get all installed application on mobile and return a list
* [user=955119]@param[/user]cContext of application
* [user=2056652]@return[/user]list of installed applications
*/
public static List<ApplicationInfo> getAllInstalledApplications(Context context) {
List<ApplicationInfo> installedApps = context.getPackageManager().getInstalledApplications(PackageManager.PERMISSION_GRANTED);
List<ApplicationInfo> launchableInstalledApps = new ArrayList<ApplicationInfo>();
for(int i =0; i<installedApps.size(); i++){
if(context.getPackageManager().getLaunchIntentForPackage(installedApps.get(i).packageName) != null){
//If you're here, then this is a launch-able app
launchableInstalledApps.add(installedApps.get(i));
}
}
return launchableInstalledApps;
}
/*
* Launch an application
* [user=955119]@param[/user]cContext of application
* [user=955119]@param[/user]pmthe related package manager of the context
* [user=955119]@param[/user]pkgNameName of the package to run
*/
public static boolean launchApp(Context c, PackageManager pm, String pkgName) {
// query the intent for lauching
Intent intent = pm.getLaunchIntentForPackage(pkgName);
// if intent is available
if(intent != null) {
try {
// launch application
c.startActivity(intent);
// if succeed
return true;
// if fail
} catch(ActivityNotFoundException ex) {
// quick message notification
Toast toast = Toast.makeText(c, "Application Not Found", Toast.LENGTH_LONG);
// display message
toast.show();
}
}
// by default, fail to launch
return false;
}
}
Sorry if I put so much code but I don't know where is the problem.

Do this:
Code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="(xmlns deleted)"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dip"

<ImageView
android:id="@+id/ivIcon"
android:layout_width="42px"
android:layout_height="42px"
android:layout_marginRight="5dip"
android:scaleType="center"
android:alignParentTop="true"
android:layout_centerHorizontal="true"
/>
<TextView
android:id="@+id/tvName"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_below="@+id/ivIcon"
/>
</RelativeLayout>
(I hope that it works. I did not test it.)

You can watch the screenshoot:
1: Thank's for your help, the text is where I want.
2: New problem, the application images are too large, I knoelw that this problem is fixeable writing text in one of the java archives.
3: The text is ajusted, but not at all, watch it.
4: Thank's other time for your time and your help!

Always set size values in dp. (You might need to change the numbers though.)
That is better for supporting different screen sizes.
Welcome.

Oh! I didn't know it.
But the problem persist, the application icon must be resized.

Yeah, do that.
You can use another scaleType for the ImageView. Use Google ("imageview scaletype"). Choose the right one.

For the ImageView change this
Code:
android:scaleType="center"
to
Code:
android:scaleType="centerInside"
Then change the layout_height and layout_width to the size you want.

Please tell me what can be the reason of this error and how can I resolve it?

Haha. :laugh:
Good job. :good:

That was funny lol.
So to recap, Clean your project and restart eclipse. If still doesn't work, delete your project and reimport it.

Cleaing project usualy fixes NoClassDefFound error, if it doest he can also try to restart eclipse and/or reimport project

No no no, you don't understand me What I mean is that I want to make the ProgressDialog visible becouse the reboot process block it.
Try to make a code that shows the ProcessDialog and then give it to me. Please...
EDIT:
What I want is show a progress dialog while a process is running, I think I need something like asynktask.

If you want the progress to.continue while doing a background task, your best and easy bet is to use async task. Create and show progress dialog in onPreExecute() and do the task in doInBackground() and close the progress in onPostExecute().

prog.show();

//Your task to be done in Background while progress dialog is showing
return null;
}
[user=439709]@override[/user]
protected void onPostExecute(Void aVoid) {

prog.dismiss(); //Progress is dismissed after background task is done
}

The ide will say of unimplemented method. Just highlight it and add unimplemented method and delete tye auto generated method. It will work then

Take you mouse pointer over AsyncTask which would be underlined in red and click on "Add unimplemented method" or something like that. Then delete the methods having the comment "// TODO Auto-generated method stub". Then the error would be gone.

With AIDE? Long-click on the code with the red mark below. Then click the first entry (something like "fix"). Select "add unimplemented methods".
That's it.

How to implement mp3 tags editor in apk?

Hi,
I'm a newbie developer and I thought that I want to add the ability to edit tags in music files (id3 tags),but I have no idea how to do that. Could somebody point me to a guide or explain me how that could be done? With parts of code if possible please.
Thanks.

You have to download this file: https://sites.google.com/site/eternalsandbox/myid3-for-android
Then, add it to your project as reference.
The code is this: (pathdata) is the path of your audio file
Code:
File src = new File(pathdata);
MusicMetadataSet src_set = null;
try {
src_set = new MyID3().read(src);
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} // read metadata
if (src_set == null) // perhaps no metadata
{
Log.i("NULL", "NULL");
}
else
{
try{
IMusicMetadata metadata = src_set.getSimplified();
String artist = metadata.getArtist();
String album = metadata.getAlbum();
String song_title = metadata.getSongTitle();
Number track_number = metadata.getTrackNumber();
Log.i("artist", artist);
Log.i("album", album);
}catch (Exception e) {
e.printStackTrace();
}
File dst = new File(pathdata);
MusicMetadata meta = new MusicMetadata("name");
meta.setAlbum("Chirag");
meta.setArtist("CS");
try {
new MyID3().write(src, dst, src_set, meta);
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ID3WriteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} // write updated metadata
Hope it's useful!

Thank you mate.
I can't find in this code a popup with sth like "type in the Artist" etc...
What do I have to do with the pathname?
How do I entirely implement it in my music player?
I'm still a newb, excuse me that.

This link can be very useful https://java.net/projects/jaudiotagger/
Anyway, you have to implement this code into your "audio editing" activity,
basically the one that have the show.audioinfo function.
The popup is already included in the library, you have only to call that
with a code lik this
Code:
Mp3File mp3file = new Mp3File("SomeMp3File.mp3");
ID3v1 id3v1Tag;
if (mp3file.hasId3v1Tag()) {
id3v1Tag = mp3file.getId3v1Tag();
} else {
// mp3 does not have an ID3v1 tag, let's create one..
id3v1Tag = new ID3v1Tag();
mp3file.setId3v1Tag(id3v1Tag);
}
id3v1Tag.setTrack("5");
id3v1Tag.setArtist("An Artist");
id3v1Tag.setTitle("The Title");
id3v1Tag.setAlbum("The Album");
id3v1Tag.setYear("2001");
id3v1Tag.setGenre(12);
id3v1Tag.setComment("Some comment");
mp3file.save("MyMp3File.mp3");
Want some real confirm? https://github.com/mpatric/mp3agic this is the ID3 guru

Thanks. After I finish something else I'll post here again if I'd have any further questions.

Replace substring from inputText

Hello all
i'm newbie
i just want to ask..
how to replace substring from textinput/input text?
this is my code
public void ngeji(EditText editText){
EditText editteks = (EditText) findViewById(R.id.editText1);
String str = editteks.getText().toString();
if(str!= null){
str.toUpperCase();
str.replaceAll("U", "OO");
str.replaceAll("C", "TJ");
str.replaceAll("F", "EV");
str.replaceAll("ES", "X");
str.replaceAll("EKS", "X");
editText.setText(str);}
}
public void normalin(EditText editText){
EditText editteks = (EditText) findViewById(R.id.editText2);
String str = editteks.getText().toString();
if(str!=null){
str.toLowerCase();
str.replaceAll("oo", "u");
str.replaceAll("tj", "c");
str.replaceAll("ev", "f");
str.replaceAll("x", "eks");
str.replaceAll("y", "i");
str.replaceAll("q", "k");
editText.setText(str);
}
}
what's wrong with the code?
btw i just wanna make translator...its like ticky word translator
for example
i = OO
j = DJ
and Uppercase all
when i type : juanda
so... the result is DJOOANDA
i'll wait for your reply
thanks

Both .toUpperCase() and .replaceAll() return a string - they do not affect the string that you run them against. So this will do nothing...
Code:
str.toUpperCase();
str.replaceAll("U", "OO");
str.replaceAll("C", "TJ");
str.replaceAll("F", "EV");
str.replaceAll("ES", "X");
str.replaceAll("EKS", "X");
This is what you want...
Code:
str = str.toUpperCase();
str = str.replaceAll("U", "OO");
str = str.replaceAll("C", "TJ");
str = str.replaceAll("F", "EV");
str = str.replaceAll("ES", "X");
str = str.replaceAll("EKS", "X");

Where do you call these methods ?
Code:
ngeji(EditText editText)
normalin(EditText editText)

^^ This, and what errors do you have?

Why are you using an edittext as an input for both functions when you are not using it.just leave brackets empty
public void function()
{
}
