Question

I have an activity which works as a pager. In this activty there are some fragments, and a ListView. Is it possible that I set the list adapter on my activity from one of my fragments?

Answer 1

You can access the Activity that holds the Fragment by calling getActivity() after onActivityCreated() in the Fragments lifecycle.

@Override
public void onActivityCreated(Bundle savedInstanceState) {
  super.onActivityCreated(savedInstanceState);
  ListView lv = (ListView) getActivity().findViewById(R.id.your_list_view);
  lv.setAdapter(yourAdapter);
}
