Question

我有一个布局，其中有一个recyclerView，其中包括两个选项卡（CustomView），根据选项卡的选择，我想更新这些选项卡下的UI。但是正如标题所述，当我尝试notifyData时，应用程序崩溃了。

我检查了类似的帖子，并尝试了以下建议： A）使用runOnUiThread呼叫notifyDataSetChange B）要使用Handler，然后再次调用notifyDataSetChange()

此外，我尝试使用notifyItemChanged(position)，但应用再次崩溃。

以下代码显示了选项卡的接口方法。我也尝试在activity上实现它，但应用程序再次崩溃。使用以下代码，当我尝试第二次更改选定的选项卡时，应用程序崩溃。

回收站适配器代码：

   override fun onSelectedTab(selectedTab: String, selectedTransaction: String) {
        presetPrepayMainModelList[adapterPosition].transactionTypeHashMap = mapOf(TRANSACTION_TYPE.ordinal to selectedTab)
        if (selectedTransaction == "preset") || selectedTransaction == "prepay") {
            presetPrepaySelectedValues.selectedTransactionType = selectedTransaction
            onPresetPrepayMainRecyclerViewListener.onTransactionTypeSelected(selectedTransaction, presetPrepayMainModelList)
            notifyItemRangeChanged(adapterPosition + 1, presetPrepayMainModelList.size)
        } else {
            presetPrepaySelectedValues.selectedTransactionLimit = selectedTransaction
            notifyItemRangeChanged(adapterPosition + 2, presetPrepayMainModelList.size)
        }
    }

错误是：

伙计们，我找到了解决我问题的方法。所以，如果将来有人需要，我会在这里发布。解决方案是使用异步任务并对列表进行更改，然后通知适配器！
