En esta sección, se documenta cómo configurar el destino del vehículo después del servidor coincide un viaje a un vehículo.
Antes de comenzar
Para esta sección, se requiere que hayas completado lo siguiente:
Cómo establecer el destino en la app del conductor
Luego de vincular a un consumidor con un conductor, debes configurar la configuración destino en la app del conductor. Para ello, sigue estos pasos:
Recuperar el destino del vehículo a partir de la colección de puntos de referencia en la flota Engine, que muestran
GetTrip()
,UpdateTrip()
yGetVehicle()
.Para establecer el destino, llama al método del SDK de Navigation para Android
setDestination()
En los siguientes ejemplos, se muestra cómo configurar el destino en el controlador .
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()
