TreeListVew+PullToRefreshListView结合使用

因为项目中有个管控区域的功能需要用到树形列表功能，于是在网上找了demo，看到了张鸿洋写了一个类似功能的demo，就参考一下，完成此功能，后续因为服务器数据不定时间会变化，要提供个刷新功能，以便于可以实时得到最新的数据，所以就想起能否和pulltorefreshlistview结合使用呢？做个下拉刷新，岂不是更好，然后就有研究了一下修改treelistview的部分代码完成了这个功能，对于treelistview不明白的可以去看张鸿洋博客http://blog.csdn.net/lmj623565791/article/details/40212367

pulltorefreshlistview的使用方法可以去github看https://github.com/chrisbanes/Android-PullToRefresh/tree/master/library

我把APK和源代码上传，可以安装看效果

因为列表中需要有选中和未选中的状态的功能，所以我们添加一个TreeNodeChecked标签来标识item的选中和未选中
