Fragment生命周期_Android Fragment详解

Fragment 生命周期其实跟 Activity 的生命周期区别不大、目前关于这块的文档也不少

我之所以写下来的目的是为了自己以后方便、另外还可以帮助一部分朋友了解 Fragment 生命周期

下面有一张图、可以形象的解说 Fragment 生命周期

场景演示 : 切换到该Fragment

11-29 14:26:35.095: D/AppListFragment(7649): onAttach

11-29 14:26:35.095: D/AppListFragment(7649): onCreate

11-29 14:26:35.095: D/AppListFragment(7649): onCreateView

11-29 14:26:35.100: D/AppListFragment(7649): onActivityCreated

11-29 14:26:35.120: D/AppListFragment(7649): onStart

11-29 14:26:35.120: D/AppListFragment(7649): onResume

屏幕灭掉：

11-29 14:27:35.185: D/AppListFragment(7649): onPause

11-29 14:27:35.205: D/AppListFragment(7649): onSaveInstanceState

11-29 14:27:35.205: D/AppListFragment(7649): onStop

屏幕解锁

11-29 14:33:13.240: D/AppListFragment(7649): onStart

11-29 14:33:13.275: D/AppListFragment(7649): onResume

切换到其他Fragment:

11-29 14:33:33.655: D/AppListFragment(7649): onPause

11-29 14:33:33.655: D/AppListFragment(7649): onStop

11-29 14:33:33.660: D/AppListFragment(7649): onDestroyView

切换回本身的Fragment:

11-29 14:33:55.820: D/AppListFragment(7649): onCreateView

11-29 14:33:55.825: D/AppListFragment(7649): onActivityCreated

11-29 14:33:55.825: D/AppListFragment(7649): onStart

11-29 14:33:55.825: D/AppListFragment(7649): onResume

回到桌面

11-29 14:34:26.590: D/AppListFragment(7649): onPause

11-29 14:34:26.880: D/AppListFragment(7649): onSaveInstanceState

11-29 14:34:26.880: D/AppListFragment(7649): onStop

回到应用

11-29 14:36:51.940: D/AppListFragment(7649): onStart

11-29 14:36:51.940: D/AppListFragment(7649): onResume

退出应用

11-29 14:37:03.020: D/AppListFragment(7649): onPause

11-29 14:37:03.155: D/AppListFragment(7649): onStop

11-29 14:37:03.155: D/AppListFragment(7649): onDestroyView

11-29 14:37:03.165: D/AppListFragment(7649): onDestroy

11-29 14:37:03.165: D/AppListFragment(7649): onDetach

比Activity多了一些生命周期，完整和Activity对接上，大家好好利用
