PullToRefreshListView

1.github下载：https://github.com/chrisbanes/Android-PullToRefresh
2.import 项目Android-PullToRefresh-master
3.将四个android的工程 拷贝到 当前的workspace中
4.会出现一些红叉叉，右击项目–>properties–>Android –>将出错的Library remove然后重新添加。
备注：只重新添加之前出错的，不要添加多余的。
5.新建一个Android项目例如HelloWorld，点击properties,将三个库Library、PulltoRefreshListFragment、PulltoRefreshViewPager全部添加。
6.将HelloWorld中libs文件夹下的android-support-v4.jar复制到其他三个项目的libs文件夹中进行替换。
7.activity_main.xml
