CommentListTextView#

说明

我是将朋友圈分成了几个独立模块单独自定义的View，通过回调完成交互，耦合性算是非常低了，主要有以下及部分：

1.评论布局（自定义TextView）

CommentListTextView

Lu_PingLunLayout

2.点赞布局（原理和评论的自定义TextView一样，都是用的SpannableString）

PraiseTextView

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）

MultiImageViewLayout

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，

示例

##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 ())

onNickNameClick (int position, CommentListTextView.CommentInfo mInfo)

“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

onToNickNameClick (int position, CommentListTextView.CommentInfo mInfo)

“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

onCommentItemClick (int position, CommentListTextView.CommentInfo mInfo)

position是第几条评论，mInfo是这条评论的信息

onOtherClick

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
