【问题描述】：
我正在使用嵌套片段并且片段加载良好。但是当我在此 frameLayout 中加载另一个片段并想再次加载嵌套片段时，我的应用程序崩溃了。

我的父片段类：
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;
}
}
编辑： 这就是我将所有片段添加到活动的方式：
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();
【问题讨论】：
-
如何将 Fragment1 和 other 添加到 Activity 中？

@MaciejGórski 我编辑了我的问题并添加了 sn-p 以将片段添加到活动中。请看一下

@ErikR 你好，是的，我已经在你提到的这个链接的帮助下解决了这个问题。请写下您的评论作为答案，以便我接受。 :D

@ErikR 不错的技巧。但我会走另一条路。始终创建所需片段的新实例。
