    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。
