I am having trouble creating a donate menu button but I am having trouble
I tried doing it as a webview but my application is the use of the listview
Code:
private static final int MENU_DONATE = 0;
Code:
/* Creates the menu items */
public boolean onCreateOptionsMenu(Menu menu)
{
menu.add(0, MENU_DONATE, 0, "Home");
return true;
}
/* Handles item selections */
@Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId()) {
case MENU_DONATE:
myweb.loadUrl("https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=A2L64XS44ZQ9S");
return true;
}
return true;
}
but it is not working and giving me errors what do i need to fix this and get it to work correctly
In my Android app, I have a sound that I want to play when a certain selection has been made from a spinner, but I want it to play the when the user actually makes the proper selection (or just after). My problem is that although the sound does play when they make the correct selection, as long as that selection stays chosen, it also plays every time the app starts up, when it should ONLY play at the time it's chosen. I think I need to change my setOnItemSelectedListener to setOnItemClickListener, but I'm not sure how (still pretty new to java). Can any generous soul out there show me how to change this up (assuming that's how to best solve this problem)?
Here is the code I have now:
Code:
fitnessSpinner = (Spinner) findViewById(R.id.fitness_spinner);
ArrayAdapter adapter4 = ArrayAdapter.createFromResource(
this, R.array.fitness_array, android.R.layout.simple_spinner_item);
adapter4.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
fitnessSpinner.setAdapter(adapter4);
fitnessSpinner.setOnItemSelectedListener(new OnItemSelectedListener()
{
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long i) {
Log.d("test", "p: " + position + " " + i);
if(position == 0) {
//First Entry
MediaPlayer mp = MediaPlayer.create(mContext, R.raw.bowchica);
mp.start();
} if(position == 4) {
MediaPlayer mp = MediaPlayer.create(mContext, R.raw.debbie2);
mp.start();
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
I haven't try the below code but you can try it on your own and tell us.
In onCreate() declare MediaPlayer mp;
In every if statement that you use for check insert this code:
Code:
if(mp!=null){mp.release();}
int resid = R.raw.yoursound;
mp = MediaPlayer.create(this, resid);
After that override the methods onPause() and onResume() and insert this:
if(mp!=null){mp.release();}
If it is still playing a sound when you start your app, then you should check your code again if you have set as default option any of your selection options.
I would LOVE to try this out...Unfortunately, I'm way too dumb at this point point ot figure out exactly where those code snippets would go inside of what I already have.
Does anyone have a couple of minutes to show me where it would go?
Below is a sample code. Since i don't know your code I give you a snippet that you should adjust it to your code.
Code:
public class SampleSound extends Activity{
private Spinner fitnessSpinner;
private MediaPlayer mp;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);//here goes your layout
setViews();//here you will set all your views(spinners buttons textviews etc..)
setAdapters();//set your adapters here
setListeners();//
}
private void setListeners() {
fitnessSpinner.setOnItemSelectedListener(new OnItemSelectedListener(){
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long i) {
Log.d("test", "p: " + position + " " + i);
if(position == 0) {
//First Entry
if(mp!=null){mp.release();}
int resid = R.raw.bowchica;
mp = MediaPlayer.create(this, resid);
mp.start();
} if(position == 4) {
if(mp!=null){mp.release();}
int resid = R.raw.debbie2;
mp = MediaPlayer.create(this, resid);
mp.start();
}
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
}
private void setAdapters() {
ArrayAdapter adapter4 = ArrayAdapter.createFromResource(this, R.array.fitness_array, android.R.layout.simple_spinner_item);
adapter4.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
fitnessSpinner.setAdapter(adapter4);
}
private void setViews() {
fitnessSpinner = (Spinner) findViewById(R.id.fitness_spinner);
}
public void onResume(){
super.onResume();
if(mp!=null){mp.release();}
}
public void onPause(){
super.onPause();
if(mp!=null){mp.release();}
}
}
I really appreciate the help. I put the code in my routine, but it still plays the sound every time the activity is loaded (as long as the selection in the spinner is correct). It should only play the sound when the correct selection is made.
Any other ideas?
I am sure that your Spinner is set to some value (since you have values to display). Because your Spinner points to a selection (doesn't matter if you have selected or it is selected by default) your sound plays (even when you start the app).
A way to stop the sound playing at start is to declare and an other Item like you did with the previous 4 and set it as default selection of your Spinner.
To sum up:
1.You have to append in R.array.fitness_array an Item (like you did with the previous Items) and give it a name.
2.At the end of method setAdapters() insert this:
Code:
fitnessSpiner.setSelection(5);// or whatever is your selection number
Now it should work but you should know that this is not a good practice and you should try make a ListView or something else.
I'd be happy to change this out to a listview, or whatever would work. I just have to give my user a choice of 4 or 5 items, from which they can choose only one. Something like a drop down box, but in Android, I thought my only option was a spinner. But whatever I use, I have to be able to play a sound when certain items are chosen, but ONLY when those items are chosen, NOT whenever the activity is called up.
Any specific ideas of what I might change to?
What if I had another control like a textview or an edittext (with it's visibility property set to false) that I programatically populated with the users selection (when it's the selection that I want) and then have an OnItemClcickListener set to play the sound?
Could that work?
I will answer from the last to the top of your questions.
1.You can do whatever you want with android. You want TextViews and EditTexts with complex and nested Layouts you can do it. Write services that will communicate with your contacts through a content provider? You can do it.
Write, read and test code. Only this way you will actually learn.
2.Read developer.android.com. Read the android tutorials from there and specifically the Notepad example. You will learn a lot.
A good resource with small examples for ListViews is this.
3.Have you tried the changes I told you from the last post? Did it worked?
Since you just started with android and programming you must first be happy if you have the expected result and then read more to make your code better
Your suggested changes (fitnessSpiner.setSelection(5);// or whatever is your selection number) would stop the sound from playing, but defeat the apps purpose. Every time this activity is loaded, the spinners hit preferences to load the previously stored data. So if I force the spinner to a different selection to NOT play sound when the activity loads, then I would be displaying the wrong data for the user.
Yes you are right. So it is better to make a ListActivity. Read developer.android.com and the link i gave you before. You will be ok with this!
You're using "setOnItemSelectedListener", which sounds like when the app starts, its getting "selected" again.
Have you tried using "setOnItemClickListener" instead?
fitnessSpinner.setOnItemClickListener(new AdapterView.OnItemClickListener () {
public void onItemClicked() {}
};

Click to expand...
Click to collapse
onClickListener doesn't work for the spinner...I wish it did.
I REALLY need the drop down functionality of teh spinner, so I guess I'm going to try and figure out a way to have an invisible edittext that I set to the spinner selection and then use onClickListener or onChange...
I have been using a hand built ListActivity as my AppWidget config Activity but to be honest it looks ****ty and doesnt fit in with the rest of the app. So i wanted to transition over to a PreferenceActivity. i made a stub of a PreferenceActivity that launches the layout just fine when it is the main activity. but when i try to change from my ListActivity to my PreferenceAcitivity i get no launching of PreferenceActivity when i launch my widget. all i get is my widget.
i did a refactoring of my xml files to change the instances of my ListActivity (GITextConfig) to my PreferenceActivity (GITextPreferences).
how can i use a PreferenceActivity as my config?
do i need to have a dummy Activity be the config with a button to launch the PreferenceActivity? cause that works just fine. its lame and shouldnt be that way... nvm that does not work... i just cant get a prefs activity to run from an appwidget
anyone? this is quite annoying... i know it can be done as other widgets like gmail unread count does this. at least it appears to have a preferenceactivity as the configuration
got it to work. i dont know what i was doing before but i think i had a little too much of a stub for it to work. after i implemented the appwidget id verification and created my PreferenceManger and overode the onBackPressed() method it seems to work.... happy and confused.
Code:
public class GITextPreferences extends PreferenceActivity {
private int mAppWidgetId = AppWidgetManager.INVALID_APPWIDGET_ID;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
PreferenceManager localPrefs = getPreferenceManager();
localPrefs.setSharedPreferencesName("GITC_Prefs");
addPreferencesFromResource(R.xml.gitc_preferences);
// Find the widget id from the intent.
Intent intent = getIntent();
Bundle extras = intent.getExtras();
if (extras != null) {
mAppWidgetId = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID);
}
// If they gave us an intent without the widget id, just bail.
if (mAppWidgetId == AppWidgetManager.INVALID_APPWIDGET_ID) {
finish();
}
}
@Override
public void onBackPressed() {
// Make sure we pass back the original appWidgetId
Intent resultValue = new Intent();
resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, mAppWidgetId);
setResult(RESULT_OK, resultValue);
finish();
}
}
I am using contextual action bar for lisview check box.I want to dismiss it programmatically to ensure that it is hidden if no check box is selected. [/code]private ActionMode.Callback mActionModeCallback = new ActionMode.Callback() {
// called when the action mode is created; startActionMode() was called
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
// Inflate a menu resource providing context menu items
MenuInflater inflater = mode.getMenuInflater();
// assumes that you have "contexual.xml" menu resources
inflater.inflate(R.menu.contextual, menu);
return true;
}
// the following method is called each time
// the action mode is shown. Always called after
// onCreateActionMode, but
// may be called multiple times if the mode is invalidated.
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
return false; // Return false if nothing is done
}
// called when the user selects a contextual menu item
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
switch (item.getItemId()) {
case R.id.cut:
getActivity().finish();
// the Action was executed, close the CAB
return true;
default :
return false;
}
}
// called when the user exits the action mode
public void onDestroyActionMode(ActionMode mode) {
mActionMode = null;
checkedindex.clear();
loadlist(new File(prog.getText().toString()));
checkedindex.clear();
selection=false;
}
};
[/Code]
I am using it like this
Code:
mActionMode = getActivity().startActionMode(mActionModeCallback);
Where mActionMode is object(Universal)
I have tried mActionMode=null; or mActionMode.finish() etc.

Hi,
currently I am developing a App.
I use the NavigationDrawer to set up a Menu (with the "Burger-Button") on the left side.
Wenn I choose a menu item, for example a PreferenceFragment i displayed.
My problem: I want to display a Tab-Layout with a PreferenceFragment in each Tab.
But I don´t know how...
In my MainActitivty-Class (AppCompatActivity) I change the content of my App (after the user clicked on a menu item) like this:
Code:
@Override
public boolean onNavigationItemSelected(MenuItem item) {
FragmentTransaction fragmentTransaction = this.getFragmentManager().beginTransaction();
int id = item.getItemId();
// Globale Eistellungen
if (id == R.id.nav_main_settings) {
fragmentTransaction.replace(R.id.containerView, new MainPreferenceMenu());
fragmentTransaction.commit();
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
Whereby "MainPreferenceMenu" is a PreferenceFragment.
I tried it with this tutorial: https://guides.codepath.com/android/google-play-style-tabs-using-tablayout
First Problem: I can´t set my PreferenceFragment here:
Code:
@Override
public Fragment getItem(int position) {
return PageFragment.newInstance(position + 1);
}
Because "PreferenceFragment" is the wring Class.
Also I don´t know how to set the "ViewPager" like in the Tutorial (MainActivity).
Can anybody help me?
I hope my Problem is clear.
Using view pager for tabs is the best option as it behaves as per material guide lines.
