Как реализовать движение рамки вместе с текущей позицией в recycleview?

Я пытаюсь добавить рамку к текущему элементу. Для смены вида item используется selector. Selector использую в корневом item следующим образом android:background="@drawable/selector_item" При смене текущего элемента рамка тоже должна передвигаться. Она передвигается, только если находится в пределах видимости. Если я вызываю scrollToPosition, когда новый элемент recycle не виден даже краем, то рамка пропадает.

            //recycle_color.get(position).constr_item.isSelected = true
            if(position==0)
            {
                recycle_color.layoutManager?.findViewByPosition(position)?.constr_item?.isSelected = false
            }
            else {
                recycle_color.layoutManager?.findViewByPosition(position)?.constr_item?.isSelected = false
            }

            val s1 = recycle_color.adapter?.itemCount
            var indexEl: Int = 0

            var currentFile = ElementCatalog(my_file, false)

            if (position == s1) {
                if (recycle_color.layoutManager?.findViewByPosition(positionItem)?.checkBox?.isChecked == true) {
                    indexEl = prod1.indexOf(currentFile)
                    prod1[indexEl].priznak = true

                    myRecycler.apply {
                        layoutManager = GridLayoutManager(context, 2)
                        adapter = CustomRecyclerAdapter(prod1, this@MainFragment)
                    }

                    val dialog = DialogFileFragment()
                    dialog.show(childFragmentManager, "custom")
                }
                position = 0
                recycle_color.layoutManager?.findViewByPosition(position)?.constr_item?.isSelected = false
            }
            else {
                position = position + 1
                recycle_color.layoutManager?.findViewByPosition(position)?.constr_item?.isSelected = true
            }
