不知道为什么会出现错误，我也添加了这两个库。

Answer 1

问题:

java.lang.IllegalStateException: RandomList must be attached to a SherlockFragmentActivity

解决方案:

你需要扩展 SherlockActivity

引用:

看看SlidingMenu usage guide ,

阅读如何将此库集成到您的项目部分中第 2 步的最后一点

“如果您想使用其他库，例如 ActionBarSherlock，您只需更改 SlidingActivities 以扩展 SherlockActivities 而不是常规 Activity ”

解释:

如上图所示，

SlidingActivity 扩展 SherlockActivity。

同样需要进行如下改动，

 - SlidingListActivity extends SherlockListActivity
 - SlidingFragmentActivity extends SherlockFragmentActivity
 - SlidingPreferenceActivity extends SherlockPreferenceActivity

注意:不要忘记将 actionbarsherlock 库添加到 SlidingMenu 的库中以访问 SherlockActivity。

希望对您有所帮助!!
