我的应用程序出现了一个奇怪的问题，在OnPause()和OnCreate()之后立即调用我的活动OnResume()。我有一些函数要在OnPause()中执行，但我不知道为什么会这样。在我的日志中显示为：
05-14 13:40:09.916: E/TestActivity(840): onCreate()
05-14 13:40:09.936: E/TestActivity(840): onResume()
**05-14 13:40:09.956: E/TestActivity(840): onPause()**
05-14 13:40:09.956: E/TestActivity(840): onResume()
