我需要创建扩展 android.app.Activity 的类 (com.mycompany.ActivityWrapper) 和 扩展以下方法：
- onCreate
- onResume
- onConfigurationChanged
- onMenuOpened
我想要我的所有活动（已经在当前 android.app.Activity、android.app.?ListActivity 处扩展） 使用我的 com.mycompany.ActivityWrapper 的代码
我不知道如何实现这个（也许通过反射％））。
请帮助我，请

我有一些相同的问题，尽管这样做让我很痛苦，但唯一有用的方法是创建多个基类。例如，您将有一个 ActivityWrapper、ListActivityWrapper、ExpandableListActivityWrapper。您可以通过将要调用的公共代码移动到一个新类（例如
ActivityExtensions）中来避免一些代码重复，您只需从各种onCreate中调用它即可。代码>方法等等。I have some of the same issues, and although it pained me to do so the only useful way of doing it is by creating multiple base classes. For example, you would have a
ActivityWrapper,ListActivityWrapper,ExpandableListActivityWrapper. You can get around some of the code duplication by moving the common code you want to call off into a new class, something likeActivityExtensions, which you just call in to from the variousonCreatemethods and so on.
