关于recyclerView快速上下滑动时的崩溃问题

转载自http://blog.csdn.net/w_lin/article/details/53019888

最近发现recyclerView快速滑动时会崩溃，百度发现是Inconsistency detected. Invalid item position 16(offset:16).state:25异常，因此我对事件进行拦截，发现依旧不查了半天才找到这个博主写的解决了我的问题，分享给大家，首先我们需要重写LinearLayoutManager方法

昨天遇到一个神奇并且很难缠的bug……
RecyclerView上下滑动的时候崩溃，崩溃信息如下：
