片段不相容类型

Question

在这里，Activity继承了ActoinBarActivity，它通过单击元素打开的片段来描述侧边栏(NavigationDrawer)。在其中一个片段中有listView，单击我想要打开的另一个片段( staff-一个员工列表-雇员数据)。但我是个错误

不兼容类型:必需: Android.app.Fragment Found:com.abc.app.EmployeeDetails

public class MyEmployeeFragment extends Fragment {
//some code
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
    userList = new ArrayList<User>();
    sAdapter = new CustomAdapter(getActivity(),userList);
    View rootView = inflater.inflate(R.layout.my_employe, container, false);
    ListView lv = (ListView)rootView.findViewById(R.id.list);
    lv.setAdapter(sAdapter);

    lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view,
        int position, long id) {
            Fragment f = new EmployeeDetails(); // ERROR
            FragmentManager fragmentManager = getFragmentManager();
            FragmentTransaction ft = fragmentManager.beginTransaction();
            ft.replace(R.id.content_frame, f);
            ft.commit();
            Log.i("TAG", "itemClick: position = " + position + ", id = "
            + id);
        }
    });

EmployeeDetails

public class EmployeeDetails extends Fragment {



    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_employee_details, container, false);
    }


}

答案是：

所有片段都必须是import android.app.Fragment;而不是android.support.v4.app.Fragment;

Answer 1

在类EmployeeDetails声明中，执行以下操作：

public class EmployeeDetails extends Fragment {
......

并使用import android.app.Fragment;

不使用import android.support.v4.app.Fragment;

Answer 2

使用import android.support.v4.app.Fragment;它的工作我。
