在继续之前，我在谷歌上搜索了这个错误，我发现了很多可用的答案，但我的情况与他们的情况不同。

java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid item position 2(offset:2).state:3

我正在使用 recyclerview 来显示投票问题，每个问题都有一个计时器，当计时器用完时，项目将从列表中删除。

当计时器用完时会发生异常，但只有在剩余时间较少(例如 100 毫秒)时才会出现这种情况。所以在这种情况下，可能是 recyclerview 正在膨胀项目，同时，计时器用完并且 recyclerview 尝试删除该项目。

错误是当计时器删除项目时出现异常。

因此，当该轮询剩余 1 秒或更短时间时，我在从数据集中删除元素后解决了这个问题。所以它不会在列表中添加项目，而是会运行计时器。

If you want to produce the bug just start countdown timer in bindView and once the timer runs out remove that particular item. You have to make timer below 500ms.

所以现在一切正常。解决了罕见情况下的崩溃，但我不想从数据集中删除元素，即使剩余时间更少。请给我这个错误的正确解决方案。

这是适配器代码。

public class PollAdapter extends RecyclerView.Adapter<PollAdapter.PollViewHolder> {

    // .... 

    @Override
    public void onBindViewHolder(@NonNull PollViewHolder holder, int position) {

    // ...

        if (holder.countDownTimer != null) {
            holder.countDownTimer.cancel();
        }

        // CountDown to set Timer in poll
        holder.countDownTimer = new CountDownTimer(<Timer to be finished.>, 1000) {

            public void onTick(long millisUntilFinished) {
                holder.time.setText("<Remaining time>");
            }

            public void onFinish() {
                removeAt(holder.getAdapterPosition());
            }

        }.start();
    }

    @Override
    public int getItemCount() {
        return pollList.size();
    }

    // To Remove Poll after Time finished
    public void removeAt(int position) {
    pollList.remove(position);
        notifyItemRemoved(position);
    }
}

最佳答案

当 RecyclerView 的 Adapter 未收到更改通知时，会出现此错误。

要解决此错误，请查找底层 Adapter 中数据发生更改的所有点。对此没有直接的解决方案，因为这是由 引发的内部崩溃回收 View

你可以做的是:

1. 由于您正在添加，因此在添加时调用 notifyItemInserted
2. 并且由于您在删除时也会调用 notifyItemRemoved

要在没有任何优化的情况下进行测试，您还可以同时调用 notifyDataSetChanged。
