Style a map

To customize the look and feel of the maps component, style your map using cloud-based maps styling or by setting options directly in code.

Style the map with cloud-based maps styling

Customize the look and feel of the maps component using cloud-based maps styling. You create and edit map styles on the Google Cloud console for any of your apps that use Google Maps, without requiring any changes to your code. For more information, see Cloud-based maps styling.

Both the ConsumerMapView and the ConsumerMapFragment classes support cloud-based maps styling. In order to use cloud-based maps styling, ensure that the selected maps renderer is LATEST. The following sections show examples of how to use cloud-based maps styling with your project.

`ConsumerMapView`

To use cloud-based maps styling in the ConsumerMapView, set the mapId field on GoogleMapOptions and pass the GoogleMapOptions to getConsumerGoogleMapAsync(ConsumerMapReadyCallback, Fragment, GoogleMapOptions) or getConsumerGoogleMapAsync(ConsumerMapReadyCallback, FragmentActivity, GoogleMapOptions)

Example

Java

public class SampleAppActivity extends AppCompatActivity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ConsumerMapView mapView = findViewById(R.id.consumer_map_view);

    if (mapView != null) {
      GoogleMapOptions optionsWithMapId = new GoogleMapOptions().mapId("map-id");
      mapView.getConsumerGoogleMapAsync(
          new ConsumerMapReadyCallback() {
            @Override
            public void onConsumerMapReady(@NonNull ConsumerGoogleMap consumerGoogleMap) {
              // ...
            }
          },
          /* fragmentActivity= */ this,
          /* googleMapOptions= */ optionsWithMapId);
    }
  }
}

Kotlin

class SampleAppActivity : AppCompatActivity() {
  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    val mapView = findViewById(R.id.consumer_map_view) as ConsumerMapView

    val optionsWithMapId = GoogleMapOptions().mapId("map-id")
    mapView.getConsumerGoogleMapAsync(
      object : ConsumerGoogleMap.ConsumerMapReadyCallback() {
        override fun onConsumerMapReady(consumerGoogleMap: ConsumerGoogleMap) {
          // ...
        }
      },
      /* fragmentActivity= */ this,
      /* googleMapOptions= */ optionsWithMapId)
  }
}

`ConsumerMapFragment`

There are two ways to use cloud-based maps styling in ConsumerMapFragments:

Statically with the XML.
Dynamically with newInstance.

Statically with the XML

To use cloud-based maps styling with the XML in the ConsumerMapFragment, add the map:mapId XML attribute with the specified mapId. See the following example:

<fragment
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    android:name="com.google.android.libraries.mapsplatform.transportation.consumer.view.ConsumerMapFragment"
    android:id="@+id/consumer_map_fragment"
    map:mapId="map-id"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

Dynamically with `newInstance`

To use cloud-based maps styling with newInstance in ConsumerMapFragment, set the mapId field on GoogleMapOptions and pass the GoogleMapOptions to newInstance. See the following example:

Java

public class SampleFragmentJ extends Fragment {

  @Override
  public View onCreateView(
      @NonNull LayoutInflater inflater,
      @Nullable ViewGroup container,
      @Nullable Bundle savedInstanceState) {

    final View view = inflater.inflate(R.layout.consumer_map_fragment, container, false);

    GoogleMapOptions optionsWithMapId = new GoogleMapOptions().mapId("map-id");
    ConsumerMapFragment consumerMapFragment = ConsumerMapFragment.newInstance(optionsWithMapId);

    getParentFragmentManager()
        .beginTransaction()
        .add(R.id.consumer_map_fragment, consumerMapFragment)
        .commit();

    consumerMapFragment.getConsumerGoogleMapAsync(
        new ConsumerMapReadyCallback() {
          @Override
          public void onConsumerMapReady(@NonNull ConsumerGoogleMap consumerGoogleMap) {
            // ...
          }
        });

    return view;
  }
}

Kotlin

class SampleFragment : Fragment() {
  override fun onCreateView(
    inflater: LayoutInflater,
    container: ViewGroup?,
    savedInstanceState: Bundle?): View? {

    val view = inflater.inflate(R.layout.consumer_map_fragment, container, false)

    val optionsWithMapId = GoogleMapOptions().mapId("map-id")
    val consumerMapFragment = ConsumerMapFragment.newInstance(optionsWithMapId)

    parentFragmentManager
      .beginTransaction()
      .add(R.id.consumer_map_fragment, consumerMapFragment)
      .commit()

    consumerMapFragment.getConsumerGoogleMapAsync(
      object : ConsumerMapReadyCallback() {
        override fun onConsumerMapReady(consumerGoogleMap: ConsumerGoogleMap) {
          // ...
        }
      })

    return view
  }
}

To apply a map style to your JavaScript consumer journey sharing map, specify a mapId and any other mapOptions when you create the JourneySharingMapView.

The following examples show how to apply a map style with a map ID.

JavaScript

const mapView = new google.maps.journeySharing.JourneySharingMapView({
  element: document.getElementById('map_canvas'),
  locationProviders: [locationProvider],
  mapOptions: {
    mapId: 'YOUR_MAP_ID'
  }
  // Any other styling options.
});

TypeScript

const mapView = new google.maps.journeySharing.JourneySharingMapView({
  element: document.getElementById('map_canvas'),
  locationProviders: [locationProvider],
  mapOptions: {
    mapId: 'YOUR_MAP_ID'
  }
  // Any other styling options.
});

Style maps directly in your own code

You can also customize map styling by setting map options when you create the JourneySharingMapView. The following examples show how to style a map using map options. For more information on what map options you can set, see mapOptions in the Google Maps JavaScript API reference.

JavaScript

const mapView = new google.maps.journeySharing.JourneySharingMapView({
  element: document.getElementById('map_canvas'),
  locationProviders: [locationProvider],
  mapOptions: {
    styles: [
      {
        "featureType": "road.arterial",
        "elementType": "geometry",
        "stylers": [
          { "color": "#CCFFFF" }
        ]
      }
    ]
  }
});

TypeScript

const mapView = new google.maps.journeySharing.JourneySharingMapView({
  element: document.getElementById('map_canvas'),
  locationProviders: [locationProvider],
  mapOptions: {
    styles: [
      {
        "featureType": "road.arterial",
        "elementType": "geometry",
        "stylers": [
          { "color": "#CCFFFF" }
        ]
      }
    ]
  }
});

Disable automatic fitting

You can stop the map from automatically fitting the viewport to the vehicle and anticipated route by disabling automatic fitting. The following example shows how to disable automatic fitting when you configure the journey sharing map view.

JavaScript

const mapView = new
    google.maps.journeySharing.JourneySharingMapView({
  element: document.getElementById('map_canvas'),
  locationProviders: [locationProvider],
  automaticViewportMode:
      google.maps.journeySharing
          .AutomaticViewportMode.NONE,
  ...
});

TypeScript

const mapView = new
    google.maps.journeySharing.JourneySharingMapView({
  element: document.getElementById('map_canvas'),
  locationProviders: [locationProvider],
  automaticViewportMode:
      google.maps.journeySharing
          .AutomaticViewportMode.NONE,
  ...
});

Replace an existing map

You can replace an existing map that includes markers or other customizations without losing those customizations.

For example, suppose you have a web page with a standard google.maps.Map entity on which a marker is shown:

    <!DOCTYPE html>
    <html>
      <head>
        <style>
           /* Set the size of the div element that contains the map */
          #map {
            height: 400px;  /* The height is 400 pixels */
            width: 100%;  /* The width is the width of the web page */
           }
        </style>
      </head>
      <body>
        <h3>My Google Maps Demo</h3>
        <!--The div element for the map -->
        <div id="map"></div>
        <script>
    // Initialize and add the map
    function initMap() {
      // The location of Pier 39 in San Francisco
      var pier39 = {lat: 37.809326, lng: -122.409981};
      // The map, initially centered at Mountain View, CA.
      var map = new google.maps.Map(document.getElementById('map'));
      map.setOptions({center: {lat: 37.424069, lng: -122.0916944}, zoom: 14});

      // The marker, now positioned at Pier 39
      var marker = new google.maps.Marker({position: pier39, map: map});
    }
        </script>
        <!-- Load the API from the specified URL.
           * The async attribute allows the browser to render the page while the API loads.
           * The key parameter will contain your own API key (which is not needed for this tutorial).
           * The callback parameter executes the initMap() function.
        -->
        <script defer src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap">
        </script>
      </body>
    </html>

To add the JavaScript fleet track library:

Add code for the authentication token factory.
Initialize a location provider in the initMap() function.
Initialize the map view in the initMap() function. The view contains the map.
Move your customization into the callback function for the map view initialization.
Add the location library to the API loader.

Map replacement example using scheduled tasks

The following examples shows how to use an existing map in which you initialize the location provider object for a scheduled task use case. The code is similar for on-demand trips use cases, except that you use the FleetEngineVehicleLocationProvider instead of the FleetEngineDeliveryVehicleLocationProvider.

    <!DOCTYPE html>
    <html>
      <head>
        <style>
           /* Set the size of the div element that contains the map */
          #map {
            height: 400px;  /* The height is 400 pixels */
            width: 100%;  /* The width is the width of the web page */
           }
        </style>
      </head>
      <body>
        <h3>My Google Maps Demo</h3>
        <!--The div element for the map -->
        <div id="map"></div>
        <script>
    let locationProvider;

    // (1) Authentication Token Fetcher
    function authTokenFetcher(options) {
      // options is a record containing two keys called
      // serviceType and context. The developer should
      // generate the correct SERVER_TOKEN_URL and request
      // based on the values of these fields.
      const response = await fetch(SERVER_TOKEN_URL);
          if (!response.ok) {
            throw new Error(response.statusText);
          }
          const data = await response.json();
          return {
            token: data.Token,
            expiresInSeconds: data.ExpiresInSeconds
          };
    }

    // Initialize and add the map
    function initMap() {
      // (2) Initialize location provider. Use FleetEngineDeliveryVehicleLocationProvider
      // as appropriate.
      locationProvider = new google.maps.journeySharing.FleetEngineDeliveryVehicleLocationProvider({
        YOUR_PROVIDER_ID,
        authTokenFetcher,
      });

      // (3) Initialize map view (which contains the map).
      const mapView = new google.maps.journeySharing.JourneySharingMapView({
        element: document.getElementById('map'),
        locationProviders: [locationProvider],
        // any styling options
      });

    mapView.addListener('ready', () => {
      locationProvider.deliveryVehicleId = DELIVERY_VEHICLE_ID;

        // (4) Add customizations like before.
        // The location of Pier 39 in San Francisco
          var pier39 = {lat: 37.809326, lng: -122.409981};
        // The map, initially centered at Mountain View, CA.
        var map = mapView.map;
        map.setOptions({center: {lat: 37.424069, lng: -122.0916944}, zoom: 14});
        // The marker, now positioned at Pier 39
        var marker = new google.maps.Marker({position: pier39, map: map});
      };
    }
        </script>
        <!-- Load the API from the specified URL
          * The async attribute allows the browser to render the page while the API loads
          * The key parameter will contain your own API key (which is not needed for this tutorial)
          * The callback parameter executes the initMap() function
          *
          * (5) Add the journey sharing library to the API loader, which includes Fleet Tracking functionality.
        -->
        <script defer
        src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap&libraries=journeySharing">
        </script>
      </body>
    </html>

If you operate a delivery vehicle with the specified ID near Pier 39, it is now rendered on the map.
