1. 当Fragment第一次被加载到屏幕上时：

11-15 13:05:26.981 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onAttach:
11-15 13:05:26.981 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onCreate:
11-15 13:05:26.981 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onCreateView:
11-15 13:05:26.982 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onActivityCreated:
11-15 13:05:26.983 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onStart:
11-15 13:05:26.984 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onResume: it

2. 另一个Fragment替换了当前Fragment，此时当前的Fragment进入了中止状态：

11-15 13:10:54.701 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onPause:
11-15 13:10:54.702 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onStop:
11-15 13:10:54.702 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onDestroyView: test

3. 按下Back键，Fragment从新回到屏幕：

11-15 13:15:15.086 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onCreateView:
11-15 13:15:15.087 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onActivityCreated:
11-15 13:15:15.087 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onStart:
11-15 13:15:15.087 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onResume: fragment

5. 再次按下Back键

11-15 13:16:48.405 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onPause:
11-15 13:16:48.405 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onStop:
11-15 13:16:48.405 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onDestroyView:
11-15 13:16:48.406 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onDestroy:
11-15 13:16:48.406 3013-3013/cn.edu.npu.fragmenttest D/RightFragment: onDetach: top
