你应该是哪个地方导包错误了，自定义viewholder已经在线上稳定运行很久了，不应该有这个bug。可以下载demo 体验一下，demo里面有内置自定义viewholder部分的代码

[YouLe2016]

没有什么问题呀，不是导包的问题，那样直接编译不过了。
会不会是集成BaseMultiItemQuickAdapter引发的错误啊

经过修改为BaseQuickAdapter 还是不行=.=,求助大神们

[qinyang1018]

我也遇见同样问题
使用版本：com.github.CymChad:BaseRecyclerViewAdapterHelper:2.9.30

升级到2.9.40同样报错

[qinyang1018]

@YouLe2016 我的找到原因了 是因为item中有一个view类型转换异常了 但是报错报的是自定义viewholder异常 所以第一时间没查到原因
