二、fragment生命周期场景演示

1.从别处切换到该fragment：onAttach->onCreate->onCreateView->onActivityCreated->onStart->onResume

2.屏幕熄灭： onPause->onSaveInstanceState->onStop

3.屏幕解锁： onStart->onResume

4.从该fragment切换到其他fragment： onPause->onStop->onDestroyView

5.从别的fragment切回到本身的fragment：onCreateView->onActivityCreated->onStart->onResume

6.回到桌面：onPause->onSaveInstanceState->onStop

7.回到应用：onStart->onResume

8.推出应用：onPause->onStop->onDestroyView->onDestroy->onDetach
