it is impossible to create a custom ListView in ListFragment

Question

I imported the library [1]: https://github.com/shontauro/android-pulltorefresh-and-loadmore

Example class was extending ListActivity and all works. I redid on extends ListFragment and there was an error.

 public class SurveyGuestsList extends ListFragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.loadmore, null);

        arrayList = new ArrayList<SurveyGuestsListBean>();
        context = getActivity();
        new LoadDataTask().execute();

//        set a listener to be invoked when the list reaches the end
        ((LoadMoreListView) getListView())
                .setOnLoadMoreListener(new OnLoadMoreListener() {
                    public void onLoadMore() {
                        // Do the work to load more items at the end of list
                        // here
                        new LoadDataTask().execute();
                    }
                });
        return v;
    }

EDITE: I moved the code here and it worked !!!

@Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        ((LoadMoreListView) getListView())
                .setOnLoadMoreListener(new OnLoadMoreListener() {
                    public void onLoadMore() {
                        // Do the work to load more items at the end of list here
                        new LoadDataTask().execute();
                    }
                });
        super.onViewCreated(view, savedInstanceState);
    }

Answer 1

Fragments and Activities have different life-cycles and call backs. For fragments, onCreateView is for creating the view it is not attached to the view hierarchy until you return v, so you cannot call getListView in it. Just create and return your view as follows.

  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.loadmore, null);
    return v;
  }

Move the rest of your code to onViewCreated() or a later callback.
