这些错误仅在我使用滑动刷新布局时发生。

在适配器的 onBindViewHolder 方法中，当最后一个项目可见时，我正在调用加载更多数据的事件

@Override
    public void onBindViewHolder(final RecyclerView.ViewHolder holder, final int position) {


        if(position == data.size() -1 && data.size() >= AppConstants.LIST_PAGE_SIZE){

            EventBus.getDefault().postSticky(new LoadMoreDataEvent(getPageIndex()));
        }
}

更新：

在清除列表后，当我尝试通知适配器时出现此错误，这是回收站视图中的错误。我只是清除列表并将适配器设置为 null 及其工作。

list.clear();
mAdapter.notifyDataSetChanged();

Answer 1

由于列表已清除，因此在获取运行后台任务的正确位置时会出现问题，因此当您在 notifydatasetchange 之前清除回收视图时，请不要使用它。使用这个：

mAdapter.notifyItemRangeInserted(0, YourArrayList.size()) 

而不是

mAdapter.notifyDataSetChanged();

Answer 2

您可能会在回收站视图中遇到错误。它已经在这里发布了 - RecyclerView: Inconsistency detected. Invalid item position
