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和控件的外观和风格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
直接在您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。

ConsumerMapView 和 ConsumerMapFragment 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) or 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 Google Maps Engine 中，您可以通过两种方式使用云端地图样式设置 ConsumerMapFragments:

使用 XML 进行静态。
与 newInstance 动态关联。

使用 XML 静态设置

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。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 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。如需了解详情，请参阅 InfoWindow。

以下示例展示了如何创建 InfoWindow 并将其附加到到车辆标记处：

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,
  ...
});
