I dont see any list in my InboxFragment why?

Date sent is in Parse DB but can't display the list in InboxFragment.

What's my mistake????

public class InboxFragment extends ListFragment {

protected List<ParseObject> mMessages;

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

    return rootView;
}

@Override
public void onResume() {
    super.onResume();

    getActivity().setProgressBarIndeterminateVisibility(true);

    ParseQuery<ParseObject> query = new ParseQuery<ParseObject>(ParseConstants.CLASS_MESSAGES);
    query.whereEqualTo(ParseConstants.KEY_RECIPIENT_IDS, ParseUser.getCurrentUser().getObjectId());
    query.addDescendingOrder(ParseConstants.KEY_CREATED_AT);
    query.findInBackground(new FindCallback<ParseObject>() {
        @Override
        public void done(List<ParseObject> messages, ParseException e) {
            getActivity().setProgressBarIndeterminateVisibility(false);

            if (e == null) {
                // We found messages!
                mMessages = messages;

                String[] usernames = new String[mMessages.size()];
                int i = 0;
                for(ParseObject message : mMessages) {
                    usernames[i] = message.getString(ParseConstants.KEY_SENDER_NAME);
                    i++;
                }
                ArrayAdapter<String> adapter = new ArrayAdapter<String>(
                        getListView().getContext(),
                        android.R.layout.simple_list_item_1,
                        usernames);
                setListAdapter(adapter);
            }
        }
    });
}

}
