9.activity真正获取焦点
https://blog.csdn.net/kinglong68/article/details/50912934
onWindowFocusChanged重要作用
相关执行打印:
1: entry: onStart---->onResume---->onAttachedToWindow----------->onWindowVisibilityChanged--visibility=0---------->onWindowFocusChanged(true)------->

2. exit: onPause---->onStop---->onWindowFocusChanged(false) ---------------------- (lockscreen)

3. exit : onPause----->onWindowFocusChanged(false)-------->onWindowVisibilityChanged--visibility=8------------>onStop(to another activity)

10.activity所有回调

11.关于onPostCreate——Activity彻底运行起来之后的回调

12.viewtreeobserver

15.调用时间顺序：
getWindow.getDecorView和onresume 调用时间顺序
onResume -- onAttachedToWindow -- getWindow.getDecorView -- onWindowFocusChanged 此时activity获取焦点
getWindow.getDecorView和onresume
