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## mPraiseTextView.setData (mPraiseInfos);//设置数据 mPraiseTextView.setNameTextColor (Color.BLUE);//设置名字字体颜色 mPraiseTextView.setIcon (R.drawable.emoji_1f0cf);//设置图标 mPraiseTextView.setMiddleStr ("，");//设置分割文本 mPraiseTextView.setIconSize (new Rect (0,0,100,100));//设置图标大小，默认与字号匹配 mPraiseTextView.setonPraiseListener()//设置监听
position是第几个点赞的人，mInfo是这条点赞的信息
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
