android - Android RecyclerView:IndexOutOfBoundsException:检测到不一致

我的RecyclerView有问题，我了解到here该错误已修复，并且我应该确保在主线程上插入数据并调用适当的notify。我做到了，但是我仍然遇到这个例外。

onLoadFinisher方法（我正在使用加载器加载更多数据）

@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor data)
{
    switch (loader.getId())
    {
        case UP_LOADER_ID:
            Log.d("Adapter", "Thread: "+Thread.currentThread().getName());
            days.put(firstDate, data);
            notifyItemRangeInserted(0, data.getCount()+1);
            loadingUp = false;
            break;

        case DOWN_LOADER_ID:
            days.put(lastDate, data);
            notifyItemRangeInserted(getItemCount(), data.getCount()+1);
            loadingDown = false;
            break;

        default:
            throw new IllegalArgumentException("Unknown loader id: " + loader.getId());
    }
}

最佳答案

您可以将getItemCount（）替换为getItemCount（）-1，因为getItemCount（）返回计数数量，但索引值为getItemCount（）-1。

 case DOWN_LOADER_ID:
        days.put(lastDate, data);
        notifyItemRangeInserted(data.getCount()-1, data.getCount()+1);
        loadingDown = false;
        break;
