ViewPager Activity to notify a Fragment of a specific event

Question

I have a ViewPager and it is using a FragmentAdapter in order to display several fragments of the same kind. Although these Fragments are basicall

Answer 1

I had the same issue but fixed it with a localBroadcastReceiver like this:

Create a receiver in your activity and register it:

 /**
 * ******************************
 * Receiver to process the message
 * *******************************
 */
private BroadcastReceiver onNotice = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        //You can send any extra data if you need like this
        final int type = intent.getIntExtra("fragment.data", -1);
        Log.d(tag, "main class: " + type);
        //also refresh your fragment like this
        mViewPager.getViewPager().getAdapter().notifyDataSetChanged();
    }
};    

@Override
protected void onResume() {
    super.onResume();

    //Register a localbroadCast with the your filter
    IntentFilter thinaireFilter = new IntentFilter("your.filter");
    LocalBroadcastManager.getInstance(this).registerReceiver(onNotice, thinaireFilter);
}

Remember to remove LocalBroadCast

//remove the LocalBroadCast when no need it
@Override
protected void onPause() {
    super.onPause();
    LocalBroadcastManager.getInstance(this).unregisterReceiver(onNotice);
}
@Override
protected void onDestroy() {
    super.onDestroy();
    LocalBroadcastManager.getInstance(this).unregisterReceiver(onNotice);
}

Send your broadcast from anywhere you want Adapters, services, etc.

Intent sendBroadCastData = new Intent("your.filter");
sendBroadCastData.putExtra("fragment.data", myData);
LocalBroadcastManager.getInstance(context).sendBroadcast(sendBroadCastData);

Hope it helps others.
