Estou usando o RecyclerView para mostrar minha lista. Eu implico o Swipe para descartar no RecyclerView com ItemTouchHelper. O layout subjacente é implementado no método OnchildDraw usando a tela. Agora estou com um problema: quero definir um clique no meu ícone. Ao clicar no ícone, quero fazer algumas funções. Aqui está a minha turma:

public class ItemTouchHelperCallback : ItemTouchHelper.SimpleCallback
{
    private ContactSearchedResultAdapter _adapter;
    private RecyclerView _mRecyclerView;
    private int _swipeCount;
    private Android.Content.Res.Resources _resources;
    public ItemTouchHelperCallback(ContactSearchedResultAdapter adapter, RecyclerView mRecyclerView, Android.Content.Res.Resources resources)
        : base(0, ItemTouchHelper.Left | ItemTouchHelper.Right)
    {
        this._adapter = adapter;
        this._mRecyclerView = mRecyclerView;
        this._resources = resources;
    }
    public override bool OnMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target)
    {
        return false;
    }

    public override void OnSwiped(RecyclerView.ViewHolder viewHolder, int direction)
    {
        if (direction == ItemTouchHelper.Left)
        {
            _adapter.RemoveViewWithDialog(viewHolder.AdapterPosition, _mRecyclerView, _swipeCount);
            if (_swipeCount == 0)
                _swipeCount++;
        }
        else
        {
            _adapter.SaveContactToDataBase(viewHolder.AdapterPosition, _mRecyclerView);
        }
    }
    public override void OnChildDraw(Canvas cValue, RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, float dX, float dY, int actionState, bool isCurrentlyActive)
    {
        Paint paint = new Paint();
        View itemView = viewHolder.ItemView;
        float height = (float)itemView.Bottom - (float)itemView.Top;
        float width = height / 3;
        Bitmap icon;

        if (dX > 0)
        {
            paint.Color = Color.ParseColor("#388E3C");
            RectF background = new RectF((float)itemView.Left, (float)itemView.Top, dX, (float)itemView.Bottom);
            cValue.DrawRect(background, paint);
            icon = BitmapFactory.DecodeResource(_resources, Resource.Drawable.addoption);
            RectF icon_dest = new RectF((float)itemView.Left + width, (float)itemView.Top + width, (float)itemView.Left + 2 * width, (float)itemView.Bottom - width);
            cValue.DrawBitmap(icon, null, icon_dest, paint);
        }
        else
        {
            paint.Color = Color.ParseColor("#D32F2F");
            RectF background = new RectF((float)itemView.Right + dX, (float)itemView.Top, (float)itemView.Right, (float)itemView.Bottom);
            cValue.DrawRect(background, paint);
            icon = BitmapFactory.DecodeResource(_resources, Res,ource.Drawable.removeoption);
            RectF icon_dest = new RectF((float)itemView.Right - 2 * width, (float)itemView.Top + width, (float)itemView.Right - width, (float)itemView.Bottom - width);
            cValue.DrawBitmap(icon, null, icon_dest, paint);
        }

        float alpha = (float)1.0- Math.Abs(dX)/(float) itemView.Width;
        itemView.Alpha = alpha;
        itemView.TranslationX = dX;

        base.OnChildDraw(cValue, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive);
    }

}

Como você pode ver, estou chamando ItemRemoving ou ItemSaving no método OnSwiped. O que eu quero fazer agora é chamar esses métodos no clique dos ícones (ícones desenhados por canvas no OnchildDraw). Pesquisei bastante sobre esse tópico e não consegui encontrar nenhuma solução que implementasse esse recurso sem usar nenhuma biblioteca. Eu não quero usar a biblioteca.
