先看看效果：
用極少的代碼實現了 動態詳情 及 二級評論 的 數據獲取與處理 和 UI顯示與交互，並且高解耦、高複用、高靈活。
動態列表界面MomentListFragment支持 下拉刷新與上拉加載 和 模糊搜索，反覆快速滑動仍然非常流暢。
緩存機制使得數據可在啓動界面後瞬間加載完成。
動態詳情界面MomentActivity支持 (取消)點贊、(刪除)評論、點擊姓名跳到個人詳情 等。
只有1張圖片時圖片放大顯示，超過1張則按九宮格顯示。
用到的CommentContainerView和MomentView都是獨立的組件，既可單獨使用，也可用於ListView或添加至其它ViewGroup等。

由於這個項目使用了ZBLibrary快速開發框架，所以實現仿QQ空間和微信朋友圈的這種複雜界面只用了極少的代碼，並且高解耦、高複用、高靈活。
服務端是用APIJSON(Server)工程快速搭建的，客戶端App和服務端通過APIJSON-JSON傳輸結構協議通信，非常方便靈活，省去了大量的接口和文檔！
今年RxJava特別火，在北京市場幾乎是必備技能，所以我還把這個項目做了個RxJava版本，歡迎交流和指教。
實現UI的Java類:
MomentListFragment 395行 動態列表的獲取和顯示
MomentActivity 616行 動態和評論列表的獲取、顯示和交互(評論和刪除評論等)
MomentAdapter 67行 動態列表的顯示
CommentAdapter 82行 評論列表的顯示
MomentView 495行 動態的顯示和交互(各種跳轉、點贊、刪除等)
EmptyEventGridView 56行 動態裏圖片的顯示和交互(觸摸空白處傳遞觸摸事件到內層View)
PraiseTextView 129行 動態裏點贊用戶的顯示和交互(點擊姓名跳到個人詳情，點擊整體跳到點讚的用戶列表界面)
CommentView 153行 一級評論(頭像、姓名、內容)的顯示和交互(回覆、刪除等)，添加二級評論列表
CommentContainerView 172行 二級評論列表的顯示和交互(查看全部等)
CommentTextView 122行 二級評論(姓名、內容)的顯示和交互(回覆、刪除等)
實現UI的XML佈局:
moment_activity 47行 動態和評論列表的顯示
moment_view 148行 動態的顯示
comment_view 87行 一級評論(頭像、姓名、內容)的顯示
comment_container_view 20行 二級評論列表的顯示
comment_item 10行 二級評論(姓名、內容)的顯示爲什麼沒有實現MomentListFragment對應的XML佈局？
因爲MomentListFragment繼承BaseHttpListFragment，內部用XListView作爲缺省列表View，所以可以不用自己實現了。
實現數據獲取、提交和處理的Java類:
HttpRequest +175行 數據的獲取和提交(getMoment,...,deleteComment)
CommentUtil 140行 單層評論和和二級評論的處理
Comment 56行 評論數據
CommentItem 99行 評論的顯示和交互數據
Moment 43行 動態數據
MomentItem 272行 動態的顯示和交互數據
User 103行 用戶數據
(注:未列出的代碼文件要麼和動態無關，要麼APIJSON或ZBLibrary已提供。server.model裏的類由服務端提供)
仿QQ空間和微信朋友圈，高解耦高複用高靈活
