場景演示 : 切換到該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 螢幕滅掉: 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

螢幕解鎖 11-29 14:33:13.240: D/AppListFragment(7649): onStart 11-29 14:33:13.275: D/AppListFragment(7649): onResume

切換到其他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

切換回本身的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 回到應用 11-29 14:36:51.940: D/AppListFragment(7649): onStart 11-29 14:36:51.940: D/AppListFragment(7649): onResume

退出應用 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多了一些生命週期,完整和Activity對接上,大家好好利用。
