Question

In my application, I have a Fragment which is attached to the main activity. This Fragment displays data with the help of an adapter. In the adapter, I have inflated a layout which has a clickable text “Watch From Home”. The adapter displays data from the server. I want to show the same data on the home screen and when I click on the “Watch From Home” text, a home screen widget should be created without any user interaction.

I made a receiver MyWidgetProvider.What should the method onClickText() for “Watch From Home” have so that it takes me to the widget? I must admit, I am new to android. Thanks

    int[] allWidgetIds2 = appWidgetManager.getAppWidgetIds(thisWidget);
    Log.w(LOG, "From Intent" + String.valueOf(allWidgetIds.length));
    Log.w(LOG, "Direct" + String.valueOf(allWidgetIds2.length));

    for (int widgetId : allWidgetIds) {
      // Create some random data
      int number = (new Random().nextInt(100));

      RemoteViews remoteViews = new RemoteViews(this
          .getApplicationContext().getPackageName(),0x7f030061);        //Since R could not be resolve, I used the generated ids
      Log.w("Widget", String.valueOf(number));
      // Set the text
      remoteViews.setTextViewText(0x7f0a022a,"Random: " + String.valueOf(number));

      // Register an onClickListener
      Intent clickIntent = new Intent(this.getApplicationContext(),MyWidgetProvider.class);

      PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 0, clickIntent,PendingIntent.FLAG_UPDATE_CURRENT);

      appWidgetManager.updateAppWidget(widgetId, remoteViews);
    }
    stopSelf();

    super.onStart(intent, startId);
  }

  @Override
  public IBinder onBind(Intent intent) {
    return null;
  }

Simply saying, You can’t create a home widget without any user interaction.

Update:

Your receiver tag should start like this:

<receiver
    android:name=".MyWidgetProvider" 
    android:label="My widget label" >
    <!-- The rest as is -->

</receiver>
