Answer 1

You should use your Fragment as this. You are not returning your View.

public class BlankFragmentTrip2 extends Fragment {

    String[] mobileArray = {"Android", "IPhone", "WindowsMobile", "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X"};

    public BlankFragmentTrip2() {
        // Required empty public constructor
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.fragment_blank_fragment_trip2, container, false);
        ArrayAdapter adapter = new ArrayAdapter<String>(getActivity(), R.layout.activity_listview, mobileArray);

        ListView listView = (ListView) rootView.findViewById(R.id.mobile_list);
        listView.setAdapter(adapter);
        return rootView;
    }

}
