Xamarin Android C# empty space after adding divider using ItemDecoration

Question

I am using a custom divider.

And I add a divider after each itemView.

divider

When I select several elements next to each other, it turns out that the divider is between them. And you can see white space on the left.

divider between items

 public OrderRecyclerViewItemDecoration(Context context, int orientation) : base(context, orientation)
    {
        Drawable = context.CompatGetDrawable(ResourceConstant.Drawable.recycler_view_divider);
    }

    public override void OnDraw(Canvas c, RecyclerView parent, RecyclerView.State state)
    {
        var childCount = parent.ChildCount;
        for (int i = 0; i < childCount; i++)
        {
            var child = parent.GetChildAt(i);
            var childPosition = parent.GetChildAdapterPosition(child);
            var viewType = parent.GetAdapter()!.GetItemViewType(childPosition);

            if (!NeedDivider(viewType))
                continue;
            
            var orderItemLeft = child.FindViewById<View>(Resource.Id.order_item_left);
            int left = orderItemLeft?.Right ?? child.Left;
            
            Drawable.Bounds = new(left, child.Bottom, child.Right, child.Bottom + Drawable.IntrinsicHeight);
            Drawable.Draw(c);
        }
    }

How can I make a divider inside each item?
