Is there a way to hide the handle when the list is not being scrolled?

When list is not in motion hide the handle. When list comes back to motion show the handle but in a fading manner.

recyclerView.addOnScrollListener(object : RecyclerView.OnScrollListener() {

            val timer = Timer()
            var task: TimerTask? = null

            override fun onScrollStateChanged(recyclerView: RecyclerView, newState: Int) {

                    RecyclerView.SCROLL_STATE_DRAGGING -> {
                        task?.cancel()
                        timer.purge()
                        task = null

                        if (binding.scrollBar.alpha != 1f) {
                            ObjectAnimator.ofFloat(binding.scrollBar.alpha, 1f).apply {
