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 14:33:55.825: 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

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