차량의 목적지 설정

이 섹션에서는 서버가 이동 경로를 차량과 일치시킨 후 차량의 목적지를 설정하는 방법을 설명합니다.

운전자 앱에서 목적지 설정

소비자를 운전자와 페어링한 후에는 다음 단계에 따라 운전자 앱에서 경로의 목적지를 구성해야 합니다.

  1. Fleet Engine의 웨이포인트 컬렉션에서 차량의 목적지를 가져옵니다. 이 컬렉션은 GetTrip(), UpdateTrip(), GetVehicle()에 의해 반환됩니다.

  2. Android용 Navigation SDK 메서드 setDestination()를 호출하여 대상을 설정합니다.

다음 예는 드라이버 앱에서 대상을 설정하는 방법을 보여줍니다.

private void navigateToLocation(LatLng locationLatLng, RoutingOptions routingOptions) {
  Waypoint destination = Waypoint.newBuilder().setLocation(locationLatLng).build();

  // Create a future to await the result of the asynchronous navigator task.
  ListenableResultFuture<Navigator.RouteStatus> pendingRoute =
      mNavigator.setDestination(destination, travelMode);

  // Define the action to perform when the SDK has determined the route.
  pendingRoute.setOnResultListener(
      new ListenableResultFuture.OnResultListener<Navigator.RouteStatus>() {
        @Override
        public void onResult(Navigator.RouteStatus code) {
          switch (code) {
            case OK:
              // Hide the toolbar to maximize the navigation UI.
              if (getActionBar() != null) {
                getActionBar().hide();
              }

              // Enable voice audio guidance (through the device speaker).
              mNavigator.setAudioGuidance(
                  Navigator.AudioGuidance.VOICE_ALERTS_AND_GUIDANCE);

                    new SimulationOptions().speedMultiplier(5));
              }

              // Start turn-by-turn guidance along the current route.
              mNavigator.startGuidance();
              break;
            // Handle error conditions returned by the navigator.

                  + String.valueOf(code));
          }
