推荐答案

纵观<一个href=\"https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/java/android/app/ExpandableListActivity.java\"相对=nofollow> ExpandableListActivity源$ C ​​$ C ，看起来它很容易在自己的类来复制相同的功能，并将它延伸 ActionBarActivity 作为它的基类。

Looking at the ExpandableListActivity source code, it seems like it would be easy to duplicate the same functionality in your own class and have it extend ActionBarActivity as its base class.
