يوضّح هذا القسم كيفية ضبط وجهة المركبة بعد أن يطابق خادمك رحلة مع مركبة.
قبل البدء
يتطلّب هذا القسم منك إكمال ما يلي:
ضبط الوجهة في تطبيق السائق
بعد إقران مستهلك بسائق، عليك ضبط وجهة الرحلة في تطبيق السائق من خلال اتّباع الخطوات التالية:
يمكنك استرداد وجهة المركبة من مجموعة نقاط الطريق في Fleet Engine التي يتم إرجاعها بواسطة
GetTrip()
وUpdateTrip()
وGetVehicle()
.اضبط الوجهة من خلال استدعاء طريقة Navigation SDK لنظام التشغيل Android
setDestination()
.
توضّح الأمثلة التالية كيفية ضبط الوجهة في تطبيق السائق.
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));
}
}
});
}
