我正在使用嵌套片段並且片段加載得很好。但是當我在此frameLayout中加載另一個片段並且想要再次加載嵌套片段時，我的應用程序崩潰。當我第二次導航到嵌套片段時，應用程序崩潰

我父片段類：
public class Fragment1 extends SherlockFragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment1, container, false);
Fragment fragmentC = new HeadlinesFragment();
Fragment frag = new Child();
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.add(R.id.child_fragment, fragmentC);
transaction.add(R.id.child_fragment2, frag);
transaction.commit();
return rootView;
}
}
編輯： 這是我所有的片段添加到活動：
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
// Locate Position
switch (position) {
case 0:
ft.replace(R.id.content_frame, fragment1);
break;
case 1:
ft.replace(R.id.content_frame, fragment2);
break;
case 2:
ft.replace(R.id.content_frame, fragment3);
break;
}
ft.commit();
如何將Fragment1和其他添加到您的活動？ –
@MaciejGórski我編輯了我的問題並添加了片段以將片段添加到活動中。請看看 –
