Xamarin Android:如何在回收器视图中获取缩减列表值

public class MyAdapter : RecyclerView.Adapter
{
    private List<string> mData;

    public MyAdapter(List<string> data)
    {
        mData = data;
    }

    public override RecyclerView.ViewHolder OnCreateViewHolder(ViewGroup parent, int viewType)
    {
        // 创建列表项视图，并返回一个ViewHolder
        View itemView = LayoutInflater.From(parent.Context).Inflate(Resource.Layout.list_item, parent, false);
        return new MyViewHolder(itemView);
    }

    public override void OnBindViewHolder(RecyclerView.ViewHolder holder, int position)
    {
        // 获取当前位置对应的值，并设置给列表项中的控件
        string value = mData[position];
        ((MyViewHolder)holder).TextView.Text = value;
    }

    public override int ItemCount => mData.Count;
}

public class MyViewHolder : RecyclerView.ViewHolder
{
    public TextView TextView { get; }

    public MyViewHolder(View itemView) : base(itemView)
    {
        TextView = itemView.FindViewById<TextView>(Resource.Id.text_view);
    }
}
