Android获得控件在屏幕中的绝对坐标

int[] location = new int[2] ;
view.getLocationInWindow(location); //获取在当前窗口内的绝对坐标
view.getLocationOnScreen(location);//获取在整个屏幕内的绝对坐标
location [0]--->x坐标,location [1]--->y坐标

@Override
    public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);
        int[] location1 = new int[2] ;
        view.getLocationInWindow(location1); //获取在当前窗口内的绝对坐标
        int[] location2 = new int[2] ;
        view.getLocationOnScreen(location2);//获取在整个屏幕内的绝对坐标
        //do something
    }
