  • 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。
