仿QQ空间动态界面分享

先看看效果：

用极少的代码实现了 动态详情 及 二级评论 的 数据获取与处理 和 UI显示与交互，并且高解耦、高复用、高灵活。

动态列表界面MomentListFragment支持 下拉刷新与上拉加载 和 模糊搜索，反复快速滑动仍然非常流畅。

缓存机制使得数据可在启动界面后瞬间加载完成。

动态详情界面MomentActivity支持 (取消)点赞、(删除)评论、点击姓名跳到个人详情 等。

只有1张图片时图片放大显示，超过1张则按九宫格显示。

用到的CommentContainerView和MomentView都是独立的组件，既可单独使用，也可用于ListView或添加至其它ViewGroup等。

由于这个项目使用了ZBLibrary快速开发框架，所以实现仿QQ空间和微信朋友圈的这种复杂界面只用了极少的代码，并且高解耦、高复用、高灵活。

服务端是用APIJSON(Server)工程快速搭建的，客户端App和服务端通过APIJSON-JSON传输结构协议通信，非常方便灵活，省去了大量的接口和文档！

今年RxJava特别火，在北京市场几乎是必备技能，所以我还把这个项目做了个RxJava版本，欢迎交流和指教。
