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);    }
