I currently have a listview and when you click on an item it runs a service with a mediaplayer. If I click on another item in the listview the service that's running should stop and run the new service. I am using a boolean isRunning set to false and when the service is created it returns true. Then in the listview I call that flag in an if statement. However, its not exactly working. I think I may be doing this wrong. Any ideas?
This probably sounds confusing the way I described it so Here is the code to my listview and my service. I am only testing this on case 3 (so I press this item to start the service and then click on case 2 to see if it will stop it).
Listview class:
public class PlaylistActivity extends ListActivity{
private static final String TAG = PlaylistActivity.class.getSimpleName();
// Data to put in the ListAdapter
private String[] sdrPlaylistNames = new String[] {
"Best of June 2011", "Best of May 2011", "Dubstep",
"House", "Other"};
private ListAdapter sdrListAdapter;
Intent playbackServiceIntentBOJ, playbackServiceIntentBOM, playbackServiceIntentDUB;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playlists_layout);
//fill the screen with the list adapter
playlistFillData();
playbackServiceIntentDUB = new Intent(this, DUBAudioService.class);
Log.d(TAG, "Made DUB Service Intent");
}
public void playlistFillData() {
//create and set up the Array adapter for the list view
ArrayAdapter sdrListAdapter = new ArrayAdapter(this, R.layout.list_item, sdrPlaylistNames);
setListAdapter(sdrListAdapter);
}
//set up the on list item Click
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
//create a switch so that each list item is a different playlist
switch(position){
case 0:
Intent BOJintent = new Intent(this, BOJAudioActivity.class);
// Create the view using PlaylistGroup's LocalActivityManager
View view = PlaylistGroup.group.getLocalActivityManager()
.startActivity("show_city", BOJintent
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
.getDecorView();
// Again, replace the view
PlaylistGroup.group.replaceView(view);
// playbackServiceIntentBOJ = new Intent(this, BOJAudioService.class);
Log.d(TAG, "Made BOJ Intent");
// startService(playbackServiceIntentBOJ);
Log.d(TAG, "started BOJ Service");
break;
case 1:
Intent BOMintent = new Intent(this, BOMAudioActivity.class);
// Create the view using PlaylistGroup's LocalActivityManager
View view2 = PlaylistGroup.group.getLocalActivityManager()
.startActivity("show_city", BOMintent
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
.getDecorView();
// Again, replace the view
PlaylistGroup.group.replaceView(view2);
Log.d(TAG, "Replace view");
//getApplicationContext().stopService(playbackServiceIntentBOJ);
//playbackServiceIntentBOM = new Intent(this, BOJAudioService.class);
Log.d(TAG, "Made BOM Service Intent");
// startService(playbackServiceIntentBOM);
Log.d(TAG, "started BOM Service");
if(DUBAudioActivity.isRunningDUB = true){
stopService(playbackServiceIntentDUB);
Log.d(TAG, "stop service isRunningDUB");
}
//
break;
case 2:
Intent DUBIntent = new Intent (this, DUBAudioActivity.class);
View view3 = PlaylistGroup.group.getLocalActivityManager()
.startActivity("show_city", DUBIntent
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
.getDecorView();
PlaylistGroup.group.replaceView(view3);
Log.d(TAG, "Replace view");
startService(playbackServiceIntentDUB);
Log.d(TAG, "started DUB service");
break;
}
