原文地址：理解Fragment生命周期
官网帮助文档链接： http://developer.Android.com/guide/components/fragments.html
主要看两张图，和跑代码
一，Fragment的生命周
二，与Activity生命周期的对比
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。
