在sdk中找到v7包
\sdk\extras\android\support\v7\recyclerview
导入工程
Import\Android\Existing Android Code Into Workspace
将导入的recycleview作为依赖库Library
工程上右键properties,勾选is Library，Apply，ok
将recycleview\libs\android_support_v7_recycleview.jar包复制粘贴到主工程的libs文件夹下
在layout中使用<android.support.v7.widget.RecyclerView/>标签
