立即删除RecyclerView中的两个项目，最后一个项目显示重复

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<String> dataList;

        this.dataList = dataList;
    }

        // 确保位置有效
        if (position1 < 0 || position1 >= dataList.size() || position2 < 0 || position2 >= dataList.size()) {
            return;
        }

        // 删除项目
        dataList.remove(position1);
        dataList.remove(position2 - 1); // 注意位置变化

        // 通知数据集变化
        notifyItemRemoved(position1);
        notifyItemRemoved(position2 - 1);
    }
