Question

我正在使用 23.1.1 RecyclerView，当滑动刷新开始时，在这种情况下，当我滚动我的 RecyclerView 时，它会崩溃并给我错误

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，当最后一项可见时，我调用了一个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:

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 View 中的错误。我只是清除列表并设置适配器为 null 及其工作。

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

Answer 1

由于列表已被清除，因此在获得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 View 时不要使用它。使用这个:

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

代替

mAdapter.notifyDataSetChanged();
