Android使用SwipeMenuListView第三方控件实现QQ中消息水平作用滑动删除置顶

       在23code上http://www.23code.com/swipemenulistview/，看类似qq消息列表中，当你进行水平滑动item时，可进行一些置顶删除等操作的效果：

      通过使用第三方开源组件SwipeMenuListView，可以实现这种效果，开源代码可以https://github.com/baoyongzhang/SwipeMenuListView下载

  之后将library中类复制到自己的项目中，或引用到自己的项目中，此处复制到自己的项目里。

先看下效果图：

接着对第三方开源组件进行使用：
