如何在谷歌地图Android中绘制折线中点的标记？

PolylineOptions polylineOptions = new PolylineOptions()
        .color(Color.RED)
        .width(5f);

// 添加折线的顶点坐标
polylineOptions.add(new LatLng(lat1, lng1));
polylineOptions.add(new LatLng(lat2, lng2));
// 添加更多顶点坐标...

Polyline polyline = googleMap.addPolyline(polylineOptions);

List<LatLng> points = polyline.getPoints();
for (int i = 0; i < points.size() - 1; i++) {
    LatLng point1 = points.get(i);
    LatLng point2 = points.get(i + 1);

    double midPointX = (point1.latitude + point2.latitude) / 2;
    double midPointY = (point1.longitude + point2.longitude) / 2;

    MarkerOptions markerOptions = new MarkerOptions()
            .position(new LatLng(midPointX, midPointY))
            .title("Midpoint");

    googleMap.addMarker(markerOptions);
}
