设置地图样式

若要自定义地图组件的外观和风格,请设置地图样式 使用云端地图样式设置或直接在代码中设置选项。

使用云端地图样式设置设置地图样式

使用云端地图自定义地图组件的外观和风格 样式。您可以在 Google Cloud 控制台上创建和修改地图样式, 而无需更改任何代码。 如需了解详情,请参阅 云端地图样式设置

ConsumerMapViewConsumerMapFragment 类支持云端地图样式设置。 若要使用云端地图样式设置,请确保所选地图 渲染程序为 LATEST。以下部分举例说明了如何使用 云端地图样式设置。

ConsumerMapView

如需在 ConsumerMapView 中使用云端地图样式设置,请将 mapId 字段,并将 GoogleMapOptions 传递给GoogleMapOptions getConsumerGoogleMapAsync(ConsumerMapReadyCallback, Fragment, GoogleMapOptions)getConsumerGoogleMapAsync(ConsumerMapReadyCallback, FragmentActivity, GoogleMapOptions)

示例

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

在 ConsumerMapFragment 中使用云端地图样式设置的方法有两种:

  • 使用 XML 进行静态。
  • newInstance 动态关联。

使用 XML 进行静态设置

若要将云端地图样式设置与 XML 中的 ConsumerMapFragment,请添加 map:mapId XML 属性(具有指定的 mapId。请参阅以下示例:

<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"/>

使用 newInstance 动态

若要将云端地图样式设置与 newInstance 搭配使用,请执行以下操作: ConsumerMapFragment,在 GoogleMapOptions 上设置 mapId 字段,并传递 从GoogleMapOptions改为newInstance。请参阅以下示例:

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
  }
}

如需将地图样式应用于 JavaScript 消费者历程共享地图,请指定 mapId和 任何其他 mapOptions JourneySharingMapView.

以下示例展示了如何使用地图 ID 应用地图样式。

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.
});

直接在您自己的代码中设置地图样式

您还可以在创建 JourneySharingMapView。以下示例展示了如何使用 地图选项。如需详细了解您可以设置哪些地图选项,请参阅 Google Maps JavaScript API 参考中的 mapOptions

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" }
        ]
      }
    ]
  }
});

停用自动调整

您可以阻止地图自动根据车辆调整视口 和预期路线。以下示例 展示了如何在配置历程共享时停用自动拟合 地图视图。

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,
  ...
});

替换现有地图

您可以替换包含标记或其他自定义设置的现有地图 而不会丢失这些自定义设置

例如,假设您有一个包含标准 google.maps.Map 的网页 显示标记的实体:

    <!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>

如需添加 JavaScript 舰队跟踪库,请执行以下操作:

  1. 添加身份验证令牌工厂的代码。
  2. initMap() 函数中初始化位置信息提供程序。
  3. initMap() 函数中初始化地图视图。该视图包含地图。
  4. 将您的自定义设置移到地图视图初始化的回调函数中。
  5. 将位置信息库添加到 API 加载器。

使用计划任务的地图替换示例

以下示例展示了如何使用现有映射,在其中为安排的任务用例初始化位置信息提供程序对象。代码与此类似 按需行程用例除外,但使用 FleetEngineVehicleLocationProvider,而不是 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>

如果您运营配送车辆 39 号码头附近的指定 ID,现在就会显示在地图上。
