android开发 获取父控件的高宽

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
 
        //获取SingleTouchView所在父布局的中心点
        ViewGroup mViewGroup = (ViewGroup) getParent();
        if(null != mViewGroup){
            mParentWidth = mViewGroup.getWidth();
            mParentHeight = mViewGroup.getHeight();
        }
 
    }
