android - ListView data not showing in fragment

Question

Here's the code that's producing unexpected results. If anyone can please guide me to what I'm doing wrong here

 public static class LaunchpadSectionFragment extends Fragment {

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

        ListView moviesList= (ListView) rootView.findViewById(R.id.movies_list);

        ArrayAdapter<String> moviesAdapter;
        List<String> Testing = new ArrayList<String>();
        Testing.add("Hey");
        Testing.add("Hey");
        Testing.add("Hey");
        Testing.add("Hey");
        moviesAdapter= new MyAdapter(getActivity(),android.R.layout.simple_list_item_1,Testing);
        moviesList.setAdapter(moviesAdapter);


return rootView;
}

好的，在浏览了很多文档之后，我终于找到了解决方法。这就是我所做的

@Override
    public void onActivityCreated(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onActivityCreated(savedInstanceState);

            super.onActivityCreated(savedInstanceState);

            Log.d("CreatedActivity", "LaunchpadFragment");
            ListView moviesList= (ListView) getActivity().findViewById(R.id.movies_list);
            // Gets the ListView from the View list of the parent activity
            // Gets a CursorAdapter

            ArrayAdapter<String> moviesAdapter;
            List<String> Testing = new ArrayList<String>();
            Testing.add("Hey");
            Testing.add("Hey Do");
            Testing.add("Hey It");
            Testing.add("Hey Please");
            moviesAdapter= new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_1, Testing);
            moviesList.setAdapter(moviesAdapter);
}

注意这里的覆盖方法，它是

onActivityCreated

Android 文档状态

如果您的片段视图是由数据适配器填充的列表视图，则应覆盖 onActivityCreated 方法并在那里进行填充。
