Question

我的RecyclerView带有动态内容，例如可以添加和删除，但是还可以，但是有一天像这样，它变得很臭而且很奇怪。

使用上个月的notifyItemInserted（）和notifyItemRangeChanged（）来更新列表的情况很好。我还尝试将依赖项更新为28.0.0，但无法正常工作。这只是一个带有RecyclerView的活动。我仍然无法弄清楚，因为那时还没有发生。

这是我的XML

我解决了一个愚蠢的错误，花了我数周的时间才弄清楚。问题的原因是声明某些商品不可回收setIsRecyclable(false)。

RecyclerView在调用notifyItemInserted和notifyItemRangeChanged
