设置地图样式

请选择平台: Android iOS JavaScript

本文档介绍了如何自定义地图的外观和风格,以及如何控制数据可见性和视口选项。为此,您可以执行以下操作:

  • 使用云端地图样式设置
  • 直接在自己的代码中设置地图样式选项

使用云端地图样式设置设置地图样式

使用云端地图样式设置来自定义地图组件的外观和风格。您可以在 Google Cloud 控制台中为使用 Google 地图的所有应用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 类都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。以下各部分举例说明了如何在项目中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,请在 GoogleMapOptions 上设置 mapId 字段,并将 GoogleMapOptions 传递给 getConsumerMapReadyCallback, 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

您可以通过以下两种方式在 ConsumerMapFragments 中使用云端地图样式设置:

  • 使用 XML 进行静态。
  • 使用 newInstance 动态创建。

使用 XML 进行静态设置

如需在 ConsumerMapFragment 中使用 XML 与云端地图样式搭配使用,请添加包含指定 mapIdmap:mapId XML 属性。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

如需在 ConsumerMapFragment 中将云端地图样式设置与 newInstance 搭配使用,请在 GoogleMapOptions 上设置 mapId 字段,并将 GoogleMapOptions 传递给 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 消费者行程分享地图,请在创建 JourneySharingMapView 时指定 mapId 和任何其他 mapOptions

以下示例展示了如何通过地图 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 时设置地图选项,从而自定义地图样式。以下示例展示了如何使用地图选项设置地图样式。如需详细了解您可以设置哪些地图选项,请参阅 Google Maps JavaScript API 参考文档中的 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" }
        ]
      }
    ]
  }
});

在地图上显示信息

使用 InfoWindow 显示与车辆或位置标记有关的其他信息。如需了解详情,请参阅 InfoWindow

以下示例展示了如何创建 InfoWindow 并将其附加到车辆标记:

JavaScript

// 1. Create an info window.
const infoWindow = new google.maps.InfoWindow(
    {disableAutoPan: true});

locationProvider.addListener('update', e => {
  const stopsCount = e.trip.remainingWaypoints.length;
  infoWindow.setContent(
      `Your vehicle is ${stopsCount} stops away.`);

  // 2. Attach the info window to a vehicle marker.
  // This property can return multiple markers.
  const marker = mapView.vehicleMarkers[0];
  infoWindow.open(mapView.map, marker);
});

// 3. Close the info window.
infoWindow.close();

TypeScript

// 1. Create an info window.
const infoWindow = new google.maps.InfoWindow(
    {disableAutoPan: true});

locationProvider.addListener('update', (e: google.maps.journeySharing.FleetEngineTripLocationProviderUpdateEvent) => {
  const stopsCount = e.trip.remainingWaypoints.length;
  infoWindow.setContent(
      `Your vehicle is ${stopsCount} stops away.`);

  // 2. Attach the info window to a vehicle marker.
  // This property can return multiple markers.
  const marker = mapView.vehicleMarkers[0];
  infoWindow.open(mapView.map, marker);
});

// 3. Close the info window.
infoWindow.close();

停用自动调整

您可以通过停用自动调整功能来阻止地图自动根据车辆和预期路线调整视口。以下示例展示了如何在配置行程分享地图视图时停用自动调整大小。

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,
  ...
});
