Questa sezione illustra come impostare la destinazione del veicolo dopo il server corrisponde a una corsa a un veicolo.
Prima di iniziare
Per questa sezione è necessario aver completato quanto segue:
Impostare la destinazione nell'app del conducente
Dopo aver accoppiato un consumatore con un conducente, devi configurare la destinazione del viaggio nell'app del conducente seguendo questi passaggi:
Recupera la destinazione del veicolo dalla raccolta delle tappe nel parco risorse Engine, che viene restituito da
GetTrip()
,UpdateTrip()
eGetVehicle()
.Imposta la destinazione chiamando il metodo SDK di navigazione per Android
setDestination()
Gli esempi riportati di seguito mostrano come impostare la destinazione nell'app per i conducenti.
Java
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);
// Simulate vehicle progress along the route for demo/debug builds.
if (BuildConfig.DEBUG) {
mNavigator.getSimulator().simulateLocationsAlongExistingRoute(
new SimulationOptions().speedMultiplier(5));
}
// Start turn-by-turn guidance along the current route.
mNavigator.startGuidance();
break;
// Handle error conditions returned by the navigator.
case NO_ROUTE_FOUND:
displayMessage("Error starting navigation: No route found.");
break;
case NETWORK_ERROR:
displayMessage("Error starting navigation: Network error.");
break;
case ROUTE_CANCELED:
displayMessage("Error starting navigation: Route canceled.");
break;
default:
displayMessage("Error starting navigation: "
+ String.valueOf(code));
}
}
});
}
Kotlin
private fun navigateToLocation(locationLatLng: LatLng, travelMode: RoutingOptions) {
val destination = Waypoint.newBuilder().setLocation(locationLatLng).build()
// Create a future to await the result of the asynchronous navigator task.
val pendingRoute = mNavigator.setDestination(destination, travelMode)
// Define the action to perform when the SDK has determined the route.
pendingRoute.setOnResultListener(
object : ListenableResultFuture.OnResultListener<Navigator.RouteStatus>() {
override fun onResult(code: Navigator.RouteStatus) {
when (code) {
Navigator.RouteStatus.OK -> {
// Hide the toolbar to maximize the navigation UI.
getActionBar()?.hide()
// Enable voice audio guidance (through the device speaker).
mNavigator.setAudioGuidance(Navigator.AudioGuidance.VOICE_ALERTS_AND_GUIDANCE)
// Simulate vehicle progress along the route for demo/debug builds.
if (BuildConfig.DEBUG) {
mNavigator
.getSimulator()
.simulateLocationsAlongExistingRoute(SimulationOptions().speedMultiplier(5))
}
// Start turn-by-turn guidance along the current route.
mNavigator.startGuidance()
}
Navigator.RouteStatus.NO_ROUTE_FOUND -> {
displayMessage("Error starting navigation: No route found.")
}
Navigator.RouteStatus.NETWORK_ERROR -> {
displayMessage("Error starting navigation: Network error.")
}
Navigator.RouteStatus.ROUTE_CANCELED -> {
displayMessage("Error starting navigation: Route canceled.")
}

}
}
