Call fragment events from activity

Question

So, I got the event in my fragment to pass to the activity, so how do I make it so the activity in turns, notifies fragment B to do something. I want to fragment B to popula

Answer 1

One way to do it would be like this in your activity:

FragmentB fragmentB = (FragmentB)getFragmentManager().findFragmentById(R.id.fragmentBId);
fragmentB.performSomeTask();

This is of course assuming that you have a publicly accessibly method in FragmentB called performSomeTask();

Hope that helps!
