分享一个ViewPager广告自动轮播

自己也写guoViewPager自动轮播 ， 但是这个人封装的确是不错，原文出处记不得了 ，拿出来也分享一下

代码下载地址 ：http://pan.baidu.com/s/1pLmgG2J

看代码吧 ，也可以直接去那个下载地址去下载，

ui_main.xml

界面代码看看方法就知道写的很干净利索，以后自己用的话，非常方便

封装的实体类

package com.stevenhu.android.phone.bean;public class ADInfo {String url;public ADInfo() {}public ADInfo(String url) {this.url = url;}public String getUrl() {return url;}public void setUrl(String url) {this.url = url;}}

剩下的三个ViewPager方法

还有一些图片资源什么的 ，可以去下载 ，一些简单的广告轮播这个就够用了 ，不用去使用第三方的banner框架什么的 。
