Answer 1

To access views that belong to the activity layout you can use

 getActivity().findViewById(R.id.viewid);

Make sure the fragment is attached to the activity and getActivity() does not return null.

Quoting docs

The fragment can access the Activity instance with getActivity() and easily perform tasks such as find a view in the activity layout
