activity中获取view的宽高以及所在屏幕中的位置

其中mBlueBall为我们想要得到相关参数的view.

如果是mBlueBall的点击事件可以直接得到宽高，原因是点击时activity已经加载了view。

mBlueBall.getRootView().getViewTreeObserver().addOnWindowFocusChangeListener(new OnWindowFocusChangeListener() {

@Override
public void onWindowFocusChanged(boolean hasFocus) {
mBlueBall.post(new Runnable() {

@Override
public void run() {
int width = mBlueBall.getWidth();
int height = mBlueBall.getHeight();
int meturewidth = mBlueBall.getMeasuredWidth();
int metureheight = mBlueBall.getMeasuredHeight();
int[] location=new int[2];
mBlueBall.getLocationOnScreen(location);
float x =location[0] ;
float y = location[1];
// x=mBlueBall.getX();
// y=mBlueBall.getY();
Log.i(TAG, "width"+width+"height"+height+"meturewidth"+meturewidth+"metureheight"+metureheight+"x"+x+"y"+y);
}
});
}


});
