Simplified in Kotlin:

 lifecycleScope.launch(Dispatchers.Main, start = CoroutineStart.DEFAULT) {
        var position = MINIMUM_POSITION
        repeat(AUTO_SCROLL_REPEATING_TIMES) {
            delay(SCROLL_DELAY)
            rvBanners.smoothScrollToPosition(position)
            when {
                position+1 == listSize -> position = 0
                position == 0 -> position = MINIMUM_POSITION
                else -> position++
            }
        }
    }

If you want to start the auto-scroll at a specific time:

val job = lifecycleScope.launch(Dispatchers.Main, start = CoroutineStart.LAZY) {
        var position = MINIMUM_POSITION
        repeat(AUTO_SCROLL_REPEATING_TIMES) {
            delay(SCROLL_DELAY)
            rvBanners.smoothScrollToPosition(position)
            when {
                position+1 == listSize -> position = 0
                position == 0 -> position = MINIMUM_POSITION
                else -> position++
            }
        }
    }
...
job.start()
