刚刚进入程序时生命周期如下：

04-11 10:55:32.968 32125-32125/lv.gx.com.fragmentlifecycle I/test: Fragment1---onAttach
04-11 10:55:32.969 32125-32125/lv.gx.com.fragmentlifecycle I/test: Fragment1---onCreate
04-11 10:55:32.969 32125-32125/lv.gx.com.fragmentlifecycle I/test: Fragment1---onCreateView
04-11 10:55:32.977 32125-32125/lv.gx.com.fragmentlifecycle I/test: Fragment1---onActivityCreated
04-11 10:55:32.978 32125-32125/lv.gx.com.fragmentlifecycle I/test: Fragment1---onStart
04-11 10:55:32.978 32125-32125/lv.gx.com.fragmentlifecycle I/test: Fragment1---onResume
04-11 10:55:32.978 32125-32125/lv.gx.com.fragmentlifecycle I/test: Fragment2---onAttach
04-11 10:55:32.978 32125-32125/lv.gx.com.fragmentlifecycle I/test: Fragment2---onCreate

04-11 10:58:38.843 2822-2822/lv.gx.com.fragmentlifecycle I/test: Fragment3---onResume

切换到第三个fragment时：

04-11 10:59:41.123 3957-3957/lv.gx.com.fragmentlifecycle I/test: Fragment1---onPause

切换到第四个fragment时：

04-11 11:03:01.545 6344-6344/lv.gx.com.fragmentlifecycle I/test: Fragment2---onPause
04-11 11:03:01.545 6344-6344/lv.gx.com.fragmentlifecycle I/test: Fragment2---onStop
