我在 android recyclerview 适配器中实现了过滤器。但问题是，当我过滤项目时，项目的位置发生了变化。我需要过滤后项目的原始位置？我怎么才能得到它？

这是我的代码：

        } else {
            this.singleHadishDisplayModels = null;
        }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        context = parent.getContext();
        View v = LayoutInflater.from(parent.getContext())

        ViewHolder vh = new ViewHolder(v, clickListener);
        return vh;
    }

    @Override
    public void onBindViewHolder(final ViewHolder holder, …
