Question

正如标题所说，我试图找到一种在iOS和Android Google Maps SDK上使用DirectionService的方法。我找到了几个关于类似解决方案的帖子;但是，我需要方向服务来获取多个航点，而不仅仅是两点之间的方向。 AFAIK，使用javascript api是唯一的方法...

我正在构建基于javascript api的离子应用，但我对移动设备上的地图性能不满意。

仅供参考，这是我在我的应用中需要的一段代码：

var request = {
    origin: origin,
    destination: destination,
    waypoints: waypoints,
    travelMode: google.maps.DirectionsTravelMode.DRIVING,
    optimizeWaypoints: document.getElementById('optimize').checked,
    avoidHighways: document.getElementById('highways').checked,
    avoidTolls: document.getElementById('tolls').checked
};

directionsService.route(request, function (response, status) {
    if(status == google.maps.DirectionsStatus.OK) {
        directionsDisplay.setDirections(response);
    }
});

有关如何在iOS / Android中实现此功能的任何建议吗？

If I am not wrong this is a hybrid app that would use Javascript to display the maps on cross platform (Android/iOS). You can directly make use of the direction service as you are already doing. For your specific questions related to the waypoints, create an array where you store two attributes, location and stopover. This way you would have various waypoints in between the origin and destination.

{
  origin: "Chicago, IL",
  destination: "Los Angeles, CA",
  waypoints: [
    {
      location:"Joplin, MO",
      stopover:false
    },{
      location:"Oklahoma City, OK",
      stopover:true
    }],
  provideRouteAlternatives: false,
  travelMode: TravelMode.DRIVING,
  unitSystem: UnitSystem.IMPERIAL
}
