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。
实现UI的Java类:
MomentListFragment 395行 动态列表的获取和显示 MomentActivity 616行 动态和评论列表的获取、显示和交互(评论和删除评论等) MomentAdapter 67行 动态列表的显示 CommentAdapter 82行 评论列表的显示 MomentView 495行 动态的显示和交互(各种跳转、点赞、删除等) EmptyEventGridView 56行 动态里图片的显示和交互(触摸空白处传递触摸事件到内层View) PraiseTextView 129行 动态里点赞用户的显示和交互(点击姓名跳到个人详情，点击整体跳到点赞的用户列表界面) CommentView 153行 一级评论(头像、姓名、内容)的显示和交互(回复、删除等)，添加二级评论列表 CommentContainerView 172行 二级评论列表的显示和交互(查看全部等) CommentTextView 122行 二级评论(姓名、内容)的显示和交互(回复、删除等)
实现UI的XML布局:
moment_activity 47行 动态和评论列表的显示 moment_view 148行 动态的显示 comment_view 87行 一级评论(头像、姓名、内容)的显示 comment_container_view 20行 二级评论列表的显示 comment_item 10行 二级评论(姓名、内容)的显示
为什么没有实现MomentListFragment对应的XML布局？
因为MomentListFragment继承BaseHttpListFragment，内部用XListView作为缺省列表View，所以可以不用自己实现了。
实现数据获取、提交和处理的Java类:
HttpRequest +175行 数据的获取和提交(getMoment,...,deleteComment) CommentUtil 140行 单层评论和和二级评论的处理 Comment 56行 评论数据 CommentItem 99行 评论的显示和交互数据 Moment 43行 动态数据 MomentItem 272行 动态的显示和交互数据 User 103行 用户数据
(注:未列出的代码文件要么和动态无关，要么APIJSON或ZBLibrary已提供。server.model里的类由服务端提供)
仿QQ空间和微信朋友圈，高解耦高复用高灵活
