Estoy usando RecyclerView para mostrar mi lista. Implemento Swipe para descartar en RecyclerView con ItemTouchHelper. El diseño subyacente se implementa en el método OnchildDraw utilizando el lienzo. Ahora tengo un problema: quiero configurar onclick en mi icono. Al hacer clic en el icono, quiero hacer algunas funciones. Aquí está mi clase:

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 puede ver, estoy llamando a ItemRemoving o ItemSaving en el método OnSwiped. Lo que quiero hacer ahora es llamar a estos métodos al hacer clic en los iconos (iconos dibujados por lienzo en OnchildDraw). Busqué mucho sobre este tema y no pude encontrar ninguna solución que implementara esta función sin usar ninguna biblioteca. No quiero usar la biblioteca.
