源码的核心类（adapter）里面几乎对每个方法都有注解。本demo主要想分享的是：
listview各种嵌套处理listview的优化处理用ImageLoader的一些特殊方式来优化图片加载listview的高度封装操作（刷新、加载更多、ui操作等）Activity动画的灵活应用下面贴出的是主界面的adapter代码：

itemView.findViewById(R.id.lv_comments_details);fl_image = (FrameLayout) itemView.findViewById(R.id.fl_image);}}}</span>
主要对单图与多图处理，对滑动优化处理，其实还开了硬件加速（android:hardwareAccelerated="true"），这样可以最大程度让listview顺畅,大图查看模仿了QQ空间的查看模式，具体的可以看源码里面的几个adapter。
能力有限，如有不足的地方欢迎指出。
