Android.view.fillateException：二进制XML文件第7行：inflating类片段时出错

Question

我知道类似这样的问题已经得到了回答，但我似乎已经做了教程建议和阅读其他帖子，但我仍然得到了充气机错误。不知道我做错了什么。请检查代码。多谢.

我也试图支持蜂巢前的版本，我想我正在导入所有的支持库。

删除导入语句：

import android.support.v4.app.FragmentActivity;

并使用弹出式导入建议再次导入。我不知道为什么，但它总是对我有效。

import android.support.v4.app.FragmentActivity;
