Gallery中点击变大

在Gallery中的图片点击后突出显示，可以使其变大，主要在onItemClick（）中加入如下代码

// gallery单击事件..
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position,
            long id) {
        View Child = mGallery.getChildAt(position);
        LayoutParams lp = Child.getLayoutParams();
        lp.height = (int) (lp.height * 1.5);
        lp.width = (int) (lp.width * 1.5);
        Child.setLayoutParams(lp);

    }
