使用支持库 v4 修订版 11 的嵌套片段

Question

今天早上的支持库的最后一个修订版（Android Support Package v4 revision 11）应该支持嵌套片段。

在我的项目中，我有一个包含ViewPager的片段

，这个ViewPager包含几个片段。

我调用getSupportFragmentManager()而不是getFragmentManager来使用支持库的 FragmentManager。

问题是我仍然遇到崩溃，例如：

我做错了什么吗？或者支持不支持真正的嵌套片段？

我的交易就是这样简单的：

getSupportFragmentManager().beginTransaction()
                    .replace(R.id.content, new MyFragment()).commit();

Answer 1

尝试使用 getChildFragmentManager() 而不是 getSupportFragmentManager() 。 这应该有帮助
