Мой код:

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

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

    TextView header = new TextView(getActivity()); 
    header.setText("Header"); 
    getListView().addHeaderView(header); 

    // ... adding objects to the adapter ... 

    ArticleAdapter adapter = new ArticleAdapter(getActivity(), android.R.layout.simple_list_item_1, android.R.id.text1, objects); 
    setListAdapter(adapter); 
} 

Я использую библиотека с прикрепленным списком.

Заранее спасибо!

Answer 1

вы пытаетесь добавить заголовок getListView(). AddHeaderView (заголовок);

это приводит к ListView, чтобы обернуть адаптер в еще один адаптер, HeaderViewListAdapter, в то время как библиотека ожидает, что это собственный адаптер

// get expected adapter or fail 
PinnedSectionListAdapter adapter = (PinnedSectionListAdapter) view.getAdapter(); 

Вы либо исправить используемую библиотеку, или после ошибки на это автора, или стараться не использовать addHeader
