Widget OnUpdate onReceive verhindern, während es aus der Widgetliste gezogen wird?

Question

Ich habe onUpdate und onReceive für mein Widget sie funktionieren gut. Aber mein Problem ist, dass sie ausgelöst werden, wenn ich Widget aus Widget-Installationsliste auf Androiden-Startbildschirm gezogen habe, ist dort sowieso, um dieses Verhalten zu verhindern?

Dies sind meine Methoden:

public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { 
     Log.e(TAG, "onUpdate()"); 

     remoteViews = new RemoteViews(context.getPackageName(), R.layout.main); 
     watchWidget = new ComponentName(context, WidgetProvider.class); 

     Intent intentClick = new Intent(context, WidgetProvider.class); 
     intentClick.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, "" + appWidgetIds[0]); 

     PendingIntent pendingIntent = PendingIntent.getBroadcast(context, appWidgetIds[0], intentClick, 0); 
     remoteViews.setOnClickPendingIntent(R.id.img_btn, pendingIntent); 
     remoteViews.setInt(R.id.img_btn, "setBackgroundResource", R.drawable.play); 

     appWidgetManager.updateAppWidget(watchWidget, remoteViews); 
    } 

    @Override 
    public void onReceive(Context context, Intent intent) { 
     super.onReceive(context, intent); 

     Log.e(TAG, "onReceive()"); 
     Bundle extras = intent.getExtras(); 

     if (extras != null) { 
      remoteViews = new RemoteViews(context.getPackageName(), R.layout.main); 

      //If isPlaying 
      if (isPlaying) { 
       //setBackground as PLAY 
       remoteViews.setInt(R.id.img_btn, "setBackgroundResource", R.drawable.play); 
       isPlaying = false; 

       Intent i = new Intent(context, MediaPlayerService.class); 
       i.putExtra("command", "stopSong"); 
       context.startService(i); 

       //If NOT playing 
      } else { 
       //setBackground as STOP 
       remoteViews.setInt(R.id.img_btn, "setBackgroundResource", R.drawable.stop); 
       isPlaying = true; 

       Intent i = new Intent(context, MediaPlayerService.class); 
       i.putExtra("command", "playRandomSong"); 
       context.startService(i); 
      } 

      watchWidget = new ComponentName(context, WidgetProvider.class); 

      (AppWidgetManager.getInstance(context)).updateAppWidget(watchWidget, remoteViews); 
     } 
    }

I intentClick.setAction(WIDGET_CLICKED); hinzugefügt, die nur dann ausgelöst wird, wenn das Widget klicken.

public class WidgetProvider extends AppWidgetProvider { 

    private static final String TAG = WidgetProvider.class.getSimpleName(); 
    private static String WIDGET_CLICKED = "widget_clicked"; 

public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { 
    Log.e(TAG, "onUpdate()"); 

    remoteViews = new RemoteViews(context.getPackageName(), R.layout.main); 
    watchWidget = new ComponentName(context, WidgetProvider.class); 

    Intent intentClick = new Intent(context, WidgetProvider.class); 
    intentClick.setAction(WIDGET_CLICKED); 
    intentClick.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, "" + appWidgetIds[0]); 

    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, appWidgetIds[0], intentClick, 0); 
    remoteViews.setOnClickPendingIntent(R.id.img_btn, pendingIntent); 
    remoteViews.setInt(R.id.img_btn, "setBackgroundResource", R.drawable.play); 

    appWidgetManager.updateAppWidget(watchWidget, remoteViews); 
} 

@Override 
public void onReceive(Context context, Intent intent) { 
    super.onReceive(context, intent); 

    Log.e(TAG, "onReceive()"); 
    Bundle extras = intent.getExtras(); 

    //If WIDGET_CLICKED 
    if (extras != null && intent.getAction().equals(WIDGET_CLICKED)) { 
     remoteViews = new RemoteViews(context.getPackageName(), R.layout.main); 

     //If isPlaying 
     if (isPlaying) { 
      //setBackground as PLAY 
      remoteViews.setInt(R.id.img_btn, "setBackgroundResource", R.drawable.play); 
      isPlaying = false; 

      Intent i = new Intent(context, MediaPlayerService.class); 
      i.putExtra("command", "stopSong"); 
      context.startService(i); 

      //If NOT playing 
     } else { 
      //setBackground as STOP 
      remoteViews.setInt(R.id.img_btn, "setBackgroundResource", R.drawable.stop); 
      isPlaying = true; 

      Intent i = new Intent(context, MediaPlayerService.class); 
      i.putExtra("command", "playRandomSong"); 
      context.startService(i); 
     } 

     watchWidget = new ComponentName(context, WidgetProvider.class); 

     (AppWidgetManager.getInstance(context)).updateAppWidget(watchWidget, remoteViews); 
    } 
}
