在两个列表片段之间导航

我知道已经有几种类似的方法，但是它们都没有帮助我，我也尝试过搜索网络，但是没有解决方案。

无论如何，我有一个从FragmentActivity启动的listfragment（fragA）。FragA包含一个按钮，单击该按钮时应打开另一个ListFragment（fragB）。

一切看起来都很好，除了我在fragB中得到了这个例外：

adapterview不支持unsupportedoperationexception addview

请问我该如何解决？

谢谢。

代码：

片段A：

public class FragA extends ListFragment {

public static ListView _listView;
private CAdapter _adapter;
private ObjCollection _data;
private Context _context;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View view = LayoutInflater.from(getActivity()).inflate(
            R.layout.layout, null);

    _listView = (ListView) view.findViewById(android.R.id.list);

    _data = new ObjCollection();

    Button btn = (Button) view.findViewById(R.id.button);
    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            NavigateFragment(new FragB(), true, FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
        }
    });

    return view;
}

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

    _adapter = new CAdapter(getActivity(), _data);
    _listView.setAdapter(_contactAdapter);

}

@Override
public void onStart() {
    super.onStart();
    getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
}

private void NavigateFragment(ListFragment listFragment, Boolean addtostack, int transition) {

    FragmentTransaction ft = getFragmentManager().beginTransaction();

    ft.replace(android.R.id.list, listFragment);
    ft.setTransition(transition);
    if (addtostack)
        ft.addToBackStack(null);

    ft.commit();

}
  }

问题B：

public static ListView _listView;

@Override

    View view = LayoutInflater.from(getActivity()).inflate(

    return view;
