首先 下载 Android-PullToRefresh-master

下载地址  

下载之后将其解压

现在  我们用eclipse 创建一个项目取名PullToRefresh 

将上面的library 引入我们的项目

引入成功之后打开项目的project.properties文件我们可以看到

android.library.reference.1=../Android-PullToRefresh-master/library

这样就表示可以引用成功了

我们在res/layout创建 布局文件main.xml

接着创建 MainActivity.java

目前编码已经完成  我们测试一下
