我尝试通过 ValueAnimator 来实现。它适用于我的任务

private fun displayRoute(pointsList: List<Point>) {
    val valueAnimator = ValueAnimator.ofInt(1, pointsList.size)
    valueAnimator.duration = 1200
    valueAnimator.addUpdateListener {
        val polylineMapObject = binding?.mapViewOrderDetail?.map?.mapObjects?.addPolyline(
            Polyline(pointsList.subList(0, it.animatedValue as Int))
        )
        polylineMapObject?.strokeColor = ContextCompat.getColor(requireActivity(), R.color.color_black)
    }
    valueAnimator.start()
}
