04-29 21:53:12.225: W/Activity(6720): onStop
04-29 21:53:12.225: W/Fragment(6720): onStop

04-29 21:53:12.245: W/Activity(6720): onCreateOptionsMenu

04-29 21:57:54.351: W/Activity(6720): onPause
04-29 21:57:54.351: W/Fragment(6720): onPause
04-29 21:57:54.881: W/Activity(6720): onStop
04-29 21:57:54.881: W/Fragment(6720): onStop
04-29 21:57:54.891: W/Activity(6720): onDestroy
04-29 21:57:54.891: W/Fragment(6720): onDestroyView
04-29 21:57:54.891: W/Fragment(6720): onDestroy
04-29 21:57:54.891: W/Fragment(6720): onDetach

以上为在onCreate动态增加的fragment

setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment()).commit();
}

如果为layout文件增加的fragment，函数周期略有不同
