RecyclerView刪除列表中的最後一項時出錯

Question

我的問題是我的recyclerview。我有刪除列表中的項目的功能。 當最後一項沒有顯示時，它工作正常。但是當最後一個項目顯示在屏幕（列表）末尾時，我從列表中刪除項目後出現錯誤。

這是我的logcat：

我刪除的項目是這樣的：

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

這裏有什麼錯？對我的問題有什麼建議嗎？謝謝！

我認爲可能是這個錯誤的原因是刪除項目我從rx線程Dispoable調用？當我在我的活動中刪除項目時，它工作正常。

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