我在我的应用程序中遇到了一个奇怪的问题，在我的 ActivityOnPause()之后立即调用OnCreate()and OnResume()。我有一些功能要在 中执行OnPause()，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()
