我正常加载回收站，数据显示正确。但我需要在特定条件下重新创建我的活动。当我重新创建我的活动时，Recycler 视图会再次初始化并加载新的数据集。但这一次我遇到了崩溃。以下是日志。任何帮助将非常感激.. ！！！

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

RecyclerView 处于锁定状态，任何更新适配器内容的尝试都会导致异常

解决方案

  • 您应该推迟recreate activity使用处理程序。
  • RecyclerView.isComputingLayout()在触发更改之前，检查应该返回 false。

就我而言，我试图通知ItemChanged（Default_pos），其中Default_pos 是-1，它不存在。

因此我得到了 ArrayIndexOutOfBound。
