android中的生命周期(新增2个函数)

onPostOnCreate()和OnPostResme()这两个函数

onPostResume()

　　Called when activity resume is complete (after onResume has been called). Applications will generally not implement this method; it is intended for 　　system classes to do final setup after application resume code has run.

onPostOnCreate()

　　Called when activity start-up is complete (after onStart and onRestoreInstanceState have been called). Applications will generally not implement this 　　method; it is intended for system classes to do final initialization after application code has run.

有文档可见,这个方法的调用位置是:

 　 正常启动: oncreate.onstart.onpostCreate.onResume.onPostResume

　　转向下一个Activity:  onPause.Onstop

　　返回到当前Activity: OnRestart.onstart.onResume.OnPostResume.

　　锁屏:OnPause.

　　点亮:onResume,onPostResume

　　旋转屏幕:onPause.onStop.onDestroy.onCreate.onStart.onPostCreate.onResume.onPostResume.

如此看来,再也不需要使用postdelay方式来等着Activity create完毕之后再干自己想干的事情了......同时也可以在oncreate中做一些操作,比如settext(),然后再OnPostCreate()中添加textwatcher,这样就可以避免监听自己设值的那个文本变化了
