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
