ArrayAdapter in Fragment - Android

Question

I get some error I don't know why. I'm populating ListView with array adapter from string in fragment. I'm using this fragment as main screen to be shown in main activity This is my code

public class HomePage extends Fragment {

private ListView lvHomePage;
private String[] items;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_home_page, container, false);

    items = getActivity().getResources().getStringArray(R.array.test);
    lvHomePage = (ListView) getActivity().findViewById(R.id.lvHomePage);

    lvHomePage.setAdapter(new ArrayAdapter<String>(getActivity().getApplicationContext(),
    android.R.layout.simple_list_item_1 , items));

    return view;
}
}

I get this output error:

Answer 1

lvHomePage must be null. Use lvHomePage = (ListView) view.findViewById(R.id.lvHomePage); instead.
