—————–内部数据模型，根据需要添加—————————————–
public interface PagerImageData{public String getImageUrl();/**用于显示网络图片*/public void setImageUrl(String imgUrl);}
——————–在Activity中使用AutoScrollViewPager——————————————————–
/**图片展示，ImageBean是项目中用到的请求服务器json数据的实体bean(要继承PagerImageData)*/private AutoScrollViewPager<ImageBean> advertiseVp;
advertiseVp = (AutoScrollViewPager<ImageBean>) findViewById(R.id.luck_detail_Vp);
你可以很有个性，但某些时候请收敛。
