Viewpager2 /Recyclerview 因不一致而崩溃

Question

在我的应用程序中遇到此崩溃。认为这是 viewpager2 的一些问题，但无法得出结论。尝试了 notifyDatasetchanged() 但无法使用它。

Process: PID: 19449
      **java.lang.IndexOutOfBoundsException:**

     **Inconsistency detected.**


     **Invalid item position 0(offset:-1).state:5

Answer 1

java.lang.IndexOutOfBoundsException:

当您尝试执行以下操作时出现此异常：

(A) 如果 List/ArrayList 已满，则在 Arraylist 或 List 中添加一个元素。

(B) 当你尝试从空 List/ArrayList 中删除一个项目时

如果您通过提及您在哪个操作或哪个类中遇到此错误来简化您的问题，这很好
