RecyclerView删除列表中的最后一项时出错

我的问题是我的recyclerview。我有删除列表中的项目的功能。当最后一项没有显示时，它工作正常。但是当最后一个项目显示在屏幕（列表）末尾时，我从列表中删除项目后出现错误。RecyclerView删除列表中的最后一项时出错

这是我的logcat：

我删除的项目是这样的：

public void delete(Entity entity) { 
     entities.remove(entity); 
     notifyDataSetChanged(); 
}

这里有什么错？对我的问题有什么建议吗？谢谢！

我认为可能是这个错误的原因是删除项目我从rx线程Dispoable调用？当我在我的活动中删除项目时，它工作正常。

您是否检查过[this]（https://stackoverflow.com/a/26479862/2910520）？ – MatPag

@MatPag Yeap。我做到了。我的xml布局没有'android：animateLayoutChanges'。 –

@PhanSinh，你的'RecyclerView'中的项目是否具有'EditText'？ – azizbekian

您可以使用notifyItemRangeChanged或notifyItemChanged方法RecyclerView适配器。

如果不调用'notifyItem ...'方法，我仍会得到这个错误。当最后一项没有显示时，它工作正常。但是当最后一个项目显示在屏幕（列表）末尾时，我从列表中删除项目后出现错误。 –
