直接贴代码了
先看看布局：
接下来看看怎么实现的

最后看看怎么用的吧

}

// TODO 单击图片处理事件
}
@Override
public void displayImage(int po, ImageView imageView) {
DisplayImageOptions options = new DisplayImageOptions.Builder().cacheOnDisc().cacheInMemory()
.showImageOnFail(R.drawable.banner1).build();
ImageLoader.getInstance().displayImage(mImageUrl.get(po), imageView, options);// 此处本人使用了ImageLoader对图片进行加装！
}
