带有两个单独ListView的TabLayout片段

Question

我有一个TabLayout的Activity。对于内容，我有一个片段;这个片段包含一个ListView。我希望为两个选项卡使用相同的片段 - 但每个都有不同的ListView。完成此任务的最佳方法是什么？这些列表都包含使用其JSON API从RottenTomatoes检索的数据。

RecentReleasesFragment.java

public class RecentReleasesFragment extends Fragment {

    private ArrayAdapter<String> mMovieAdapter;
    private ArrayAdapter<String> mDVDAdapter;
    private int mPage;
    public static final String ARG_PAGE = "ARG_PAGE";

    /**
     * Constructor for the RecentReleasesFragment
     * @param page fragment is on
     * @return newly created fragment
     */
    public static RecentReleasesFragment newInstance(int page) {
        Bundle args = new Bundle();
        args.putInt(ARG_PAGE, page);
        RecentReleasesFragment fragment = new RecentReleasesFragment();
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mPage = getArguments().getInt(ARG_PAGE);
    }

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

        switch(mPage) {
            case 1:
                FetchMovies taskMovie = new FetchMovies();
                taskMovie.execute();
                recentMoviesList(view);
            case 2:
                FetchDVDs taskDVD = new FetchDVDs();
                taskDVD.execute();
                recentDVDsList(view);
        }
        return view;
    }

    public void recentMoviesList(View v) {
        ListView mRecentMoviesList = (ListView) v.findViewById(R.id.listview_recent_movies);
        mMovieAdapter = new ArrayAdapter<>(
                getActivity(),
                R.layout.list_item_film,
                R.id.list_item_film,
                new ArrayList<String>());
        mRecentMoviesList.setAdapter(mMovieAdapter);
    }

    public void recentDVDsList(View v) {
        ListView mRecentDVDsList = (ListView) v.findViewById(R.id.listview_recent_movies);
        mDVDAdapter = new ArrayAdapter<>(
                getActivity(),
                R.layout.list_item_film,
                R.id.list_item_film,
                new ArrayList<String>());
        mRecentDVDsList.setAdapter(mDVDAdapter);
    }
    //adds items to mMovieAdapter
    public class FetchMovies extends AsyncTask<String, Void, String[]> { . . . 
        @Override
        protected void onPostExecute(String[] result) {
            if (result != null) {
                mMovieAdapter.clear();
                for (String movie : result) {
                    mMovieAdapter.add(movie);
                }
            }
        }
    }


    //adds items to mDVDAdapter
    public class FetchDVDs extends AsyncTask<String, Void, String[]> { . . . }
}
