在这里SDK颜色仅是路线的一部分 [英] HERE SDK Color only part of the route

问题描述

有没有一种方法可以只用不同的颜色给路线的一部分上色? 就像画一条多段线一样，但它要考虑道路配置.

Is there a way to color only a part of the route in a different color? Like drawing a polyline but one that takes the road configuration into consideration.

推荐答案

您可以提取路径几何以获取构成折线的GeoCoordinates列表:

You can extract the route geometry to get the list of GeoCoordinates constituing the polyline:

geoCoordinates = mapRoute.getRoute().getRouteGeometry()

然后，您可以根据这些坐标构建新的折线，以各种颜色绘制路线的各个部分:

Then you can draw portions of the route in various colors by building new polylines from these coordinates:

GeoPolyline geoPolyline = new GeoPolyline();
for (GeoCoordinates point : geoCoordinates) {
    if (<your condition>){
        geoPolyline.add(point);
    }
}
MapPolyline mapPolyline = new MapPolyline(geoPolyline);
mapPolyline.setLineColor(<color>);
map.addMapObject(mapPolyline)
