高德路径规划,自定义骑行路线(适用3D地图)

1,规划路径

LatLonPoint latLonPoint1 = new LatLonPoint(xxx,xxx);
LatLonPoint latLonPoint2 = new LatLonPoint(xxx,xxx);
RouteSearch mRouteSearch = new RouteSearch(this);
mRouteSearch.setRouteSearchListener(this);
final RouteSearch.FromAndTo fromAndTo = new RouteSearch.FromAndTo(
        latLonPoint1, latLonPoint2);
RouteSearch.RideRouteQuery query = new RouteSearch.RideRouteQuery(fromAndTo, RouteSearch.RidingDefault);
mRouteSearch.calculateRideRouteAsyn(query);// 异步路径规划骑行模式查询

2,监听并得到路径规划结果

@Override
public void onBusRouteSearched(BusRouteResult driveRouteResult, int i) {

}

@Override
public void onDriveRouteSearched(DriveRouteResult driveRouteResult, int i) {

}

@Override
public void onWalkRouteSearched(WalkRouteResult walkRouteResult, int i) {

}

@Override
public void onRideRouteSearched(RideRouteResult rideRouteResult, int i) {
    RidePath drivePath = rideRouteResult.getPaths().get(0);
    RideRouteOverlay drivingRouteOverlay = new RideRouteOverlay(this, aMap, drivePath, rideRouteResult.getStartPos(), rideRouteResult.getTargetPos());//自定义路径样式
    drivingRouteOverlay.setNodeIconVisibility(false);//隐藏转弯的节点
    drivingRouteOverlay.addToMap();
    drivingRouteOverlay.zoomToSpan();
}

3,自定义路径样式
