怎么在Actuvity已启动的时候获取view的宽/高

1、onWindowFocusChanged

  这个方法的含义是：View已经初始化完毕了，宽/高已经准备好了，这个时候去获取宽/高是没有问题的。

public void onWindo...(boolean hasFocus){

super.onWindowFocusChanged(hasFocus){

if(hasFocus){

int width = view.getMeasuredWidth();

int height = view.getMeasuredHeight();

}

}

}

2、view.post(runnable)

protected void onStart(){

super.onStart();

view.post(new Runnable()){

public void run(){

int width = view.getMeasuredWidth();

int height = view.getMeasuredHeight();

}

}

}
