在RecolyerView中检测到不一致，如何在滚动时更改RecolyerView的内容

Question

我正在使用recyclerview显示项目的名称。我的行包含单个textview。项名存储在list mitemlist 中。

若要更改RecolyerView的内容，我将替换MitemList中的字符串，并在RecolyerViewAdapter上调用NotifyDataSetChanged()。

但是，如果我试图在RecyclerView滚动时更改MitemList的内容，有时它会给我java.lang.IndexOutOfBoundsException：Inconsistency Detection。无效的项目位置157（偏移量：157）。状态:588

如果mitemlist的大小比以前小，就会发生这种情况。那么，更改RecyclerView内容的正确方法是什么？这是recyclerview中的bug吗？

以下是异常的完整堆栈跟踪：

编辑：这个错误现在已经修复了，如果您仍然得到相同的异常，请确保您只是从主线程更新您的适配器数据源，然后调用相应的适配器notify方法。

老答案：这似乎是recyclerview中的一个bug，这里和这里都有报告。希望它能在下一个版本中得到修正。
