AbsoluteLayout ImageView.getLayoutParams（）为x和y返回零值

Question

在按钮点击事件中，我设置图像按钮的x和y值，点击另一个按钮后我想通过添加x = x + 10但layoutParams.y之类的值再次更改其坐标0几秒前它已经设定;

            AbsoluteLayout.LayoutParams lp = new AbsoluteLayout.LayoutParams(hand.getLayoutParams());
            Log.d("mangala",String.format("b pos %d", lp.y ));
            lp.y = lp.y - g.convertDPtoPX(30f);
            Log.d("mangala",String.format("a pos %d", lp.y ));
            hand.setLayoutParams(lp);

感谢。
