1.评论布局（自定义TextView）
2.点赞布局（原理和评论的自定义TextView一样，都是用的SpannableString）
3.图片列表（出门右转，理论上没有数量限制，和listView配合使用也很好，缓存也自己处理了）
我也是找第三方例子不好找，于是自己写了一个，我和同事还打算做一套IM系统，app和后台都要做，我们自己定义sdk，我们还要封装H5，类似hbuilder如果有什么问题，可以联系我，

##主要方法##
####设置评论最大显示行数####
mCommentListTextView.setMaxlines (6);
####设置超过最大行数下面显示的提示文本####
mCommentListTextView.setMoreStr ("查看更多");
####设置名字文本显示颜色####
mCommentListTextView.setNameColor (Color.parseColor ("#fe671e"));
####设置评论内容文本颜色####
mCommentListTextView.setCommentColor (Color.parseColor ("#242424"));
####设置名字之间的文本####
mCommentListTextView.setTalkStr ("回复");
####设置名字之间的文本颜色####
mCommentListTextView.setTalkColor (Color.parseColor ("#242424"));
####设置显示数据####
mCommentListTextView.setData (mCommentInfos);
####设置监听
mCommentListTextView.setonCommentListener (new CommentListTextView.onCommentListener ())
“A回复B”中A名称被点击 position是第几条评论，mInfo是这条评论的信息
“A回复B”中B名称被点击 position是第几条评论，mInfo是这条评论的信息
position是第几条评论，mInfo是这条评论的信息
内部处理了点击文字会触发两个回调的问题，这个是点击非文字或者没有单独定义点击事件的回调
