我正常加载回收器并正确显示数据。但是我要求在某种条件下重新创造我的活力。当我重新创建我的活动时，再次初始化Recycler视图并加载新的数据集。但是这次我遇到了崩溃。以下是日志。任何帮助都会非常感激.. !!!

Answer 1

就我而言，我正在尝试notifyItemChanged（Default_pos），其中Default_pos为-1，但不存在。

因此我得到了ArrayIndexOutOfBound。

Answer 2

当您尝试重新创建activity时，RecyclerView仍在尝试显示view items和ComputingLayout

RecyclerView处于锁定状态，并且任何尝试更新适配器内容将导致异常

<强>解决方案

您应该使用处理程序推迟recreate activity。
在您触发更改之前，检查RecyclerView.isComputingLayout()应返回false。
