ListView：onContentChanged完成

Question

我使用实现LoaderManager的自定义ListFragment构建ListView，自定义ArrayAdapter和自定义AsyncTaskLoader。 我想要做的是从数据库表中加载ListView（可行）。如果我有一个SharedPreference，我在数据库中添加一行，然后通过广播接收器（可以正常工作）请求更新ListView，并最终编辑ListView以隐藏TextView并显示EditText（它没有#t;作品）。 当我试图访问方法中的特定行时

public void onLoadFinished(Loader<List<Favoris>> loader, List<Favoris> data)

我有一个nullPointer异常。我想问题是onContentChanged（）方法没有完成，ListView也没有完全更新。 你知道我应该在哪里移动代码的最后一部分吗？ （而不是把它放在onLoadFinished中）

编辑：

public static class FavListFragment extends ListFragment implements LoaderManager.LoaderCallbacks<List<Favoris>> {
  private static final String TAG = "ADP_AppListFragment";
  private static final boolean DEBUG = true;

  // We use a custom ArrayAdapter to bind application info to the ListView.
  private FavoritesListAdapter mAdapter;

  // The Loader's id (this id is specific to the ListFragment's LoaderManager)
  private static final int LOADER_ID = 1;

  @Override
  public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    setHasOptionsMenu(false);

    mAdapter = new FavoritesListAdapter(getActivity());
    setEmptyText("No applications");
    setListAdapter(mAdapter);
    setListShown(false);

    if (DEBUG) {
      Log.i(TAG, "+++ Calling initLoader()! +++");
      if (getLoaderManager().getLoader(LOADER_ID) == null) {
        Log.i(TAG, "+++ Initializing the new Loader... +++");
      } else {
        Log.i(TAG, "+++ Reconnecting with existing Loader (id '1')... +++");
      }
    }

    // Initialize a Loader with id '1'. If the Loader with this id already
    // exists, then the LoaderManager will reuse the existing Loader.
    getLoaderManager().initLoader(LOADER_ID, null, this);
  }
