Traffic examples
Have a look at our functional examples to see how easy it is to implement search features with the Maps SDK. Speed up development by using our sample code snippets in your app. Try all of this out with the Maps SDK Examples app!
Traffic incident list
Give your users information about traffic incidents so they can adjust their commute according to the traffic situation.
Sample use case: You are about to drive and you want to avoid roads with traffic incidents on your way. Use the traffic incident list to have an overview of which streets might be blocked or congested due to accidents, road works, or possible rain, ice, flooding, etc.
Use the following code snippet to try this in your app.
_
return IncidentDetailsQueryBuilder.create(IncidentStyle.S1, LONDON_BOUNDING_BOX, DEFAULT_ZOOM_LEVEL_FOR_EXAMPLE, "-1")
.withExpandCluster(true)
.build();IncidentDetailsQueryBuilder.create(IncidentStyle.S1, LONDON_BOUNDING_BOX, DEFAULT_ZOOM_LEVEL_FOR_EXAMPLE, TRAFFIC_MODEL_ID)
.withExpandCluster(true)
.build()
An example implementation of a listener to the response from the traffic incident details service:
_
private IncidentDetailsResultListener incidentDetailsResultListener = new IncidentDetailsResultListener() {
@Override
public void onTrafficIncidentDetailsResult(IncidentDetailsResponse result) {
final List<TrafficIncidentItem> items = new ArrayList<>();
TrafficIncidentVisitor visitor = new TrafficIncidentVisitor() {
@Override
public void visit(TrafficIncidentCluster cluster) {
items.add(incidentItemCreator.createClusterOfIncidents(cluster));
}
@Override
public void visit(TrafficIncident incident) {
items.add(incidentItemCreator.createSingleIncident(incident));
}
};
for (BaseTrafficIncident incident : result.getIncidents()) {
incident.accept(visitor);
}
view.updateTrafficIncidentsList(items);
}
@Override
public void onTrafficIncidentDetailsError(Throwable error) {
Toast.makeText(view.getContext(), error.getMessage(), Toast.LENGTH_SHORT).show();
}
};private val incidentDetailsResultListener = object : IncidentDetailsResultListener {
override fun onTrafficIncidentDetailsResult(result: IncidentDetailsResponse) {
listOfIncidents.clear()
context?.let { ctx ->
trafficIncidentItemCreator = TrafficIncidentItemCreator(ctx)
result.incidents.forEach { incident ->
incident.accept(trafficVisitor)
}
trafficIncidentAdapter.updateData(listOfIncidents)
}
}
override fun onTrafficIncidentDetailsError(error: Throwable) {
Toast.makeText(view?.context, error.message, Toast.LENGTH_SHORT).show()
}
}private val trafficVisitor = object : TrafficIncidentVisitor {
override fun visit(cluster: TrafficIncidentCluster) {
listOfIncidents.add(trafficIncidentItemCreator.createClusterOfIncidents(cluster))
}
override fun visit(incident: TrafficIncident) {
listOfIncidents.add(trafficIncidentItemCreator.createSingleIncident(incident))
}
}
It is also possible to obtain drawable for every traffic incident. It can be done via 'TrafficIncidentIconProvider' object.
_
TrafficIncidentIconProvider provider = new TrafficIncidentIconProvider(incident);
Drawable incidentDrawable = provider.getIcon(context, TrafficIncidentIconProvider.IconSize.LARGE);val provider = TrafficIncidentIconProvider(incident)
val incidentDrawable = provider.getIcon(context, TrafficIncidentIconProvider.IconSize.LARGE)
