設定地圖樣式

如要自訂地圖元件的外觀和風格，請設定地圖樣式使用雲端式地圖樣式設定，或直接在程式碼中設定選項。

使用雲端式地圖樣式設定設定地圖樣式

使用雲端式地圖自訂地圖元件的外觀與風格樣式。如要在 Google Cloud 控制台中建立及編輯地圖樣式，您完全不需要修改程式碼。若需更多資訊，請參閲雲端式地圖樣式設定。

兩者 ConsumerMapView 和 ConsumerMapFragment 類別支援雲端式地圖樣式設定。如要使用雲端式地圖樣式設定，請確認所選地圖轉譯器為 LATEST。下列各節提供使用範例雲端式地圖樣式設定。

`ConsumerMapView`

如要在 ConsumerMapView 中使用雲端式地圖樣式設定，請設定 GoogleMapOptions 的 mapId 欄位，並將 GoogleMapOptions 傳遞至 getConsumerGoogleMapAsync(ConsumerMapReadyCallback, Fragment, GoogleMapOptions) or getConsumerGoogleMapAsync(ConsumerMapReadyCallback, FragmentActivity, GoogleMapOptions)

範例

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`

在以下項目中使用雲端式地圖樣式設定的方法有兩種： ConsumerMapFragments:

使用 XML 靜態。
使用 newInstance 動態。

使用 XML 靜態

如要搭配 XML 中的 XML 使用雲端式地圖樣式設定， ConsumerMapFragment，以指定的 map:mapId XML 屬性新增 mapId。請參閱以下範例：

<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`」動態

如要在以下位置使用雲端式地圖樣式設定：newInstance ConsumerMapFragment，在 GoogleMapOptions 上設定 mapId 欄位，並傳遞 GoogleMapOptions 至 newInstance。請參閱以下範例：

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
  }
}

如要將地圖樣式套用至 JavaScript 消費者歷程共用地圖，請指定 mapId 和任何其他 mapOptions 在您建立 JourneySharingMapView 時啟用。

以下範例說明如何套用具有地圖 ID 的地圖樣式。

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.
});

直接在自己的程式碼中設定地圖樣式

您也可以在建立地圖時，設定地圖選項來自訂地圖樣式 JourneySharingMapView。下例示範如何使用地圖選項。若要進一步瞭解可設定的地圖選項，請參閱： mapOptions Google Maps JavaScript API 參考資料中。

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" }
        ]
      }
    ]
  }
});

停用自動合框功能

你可以讓地圖不自動根據車輛調整可視區域並停用自動合照功能。以下範例顯示如何在設定歷程共用時停用自動合框功能地圖檢視。

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,
  ...
});

取代現有地圖

您可以取代含有標記或其他自訂項目的現有地圖而不會失去這些自訂設定

舉例來說，假設您的網頁含有標準 google.maps.Map 顯示標記的實體：

    <!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>

如要新增 JavaScript 機群測試群組：

新增驗證權杖工廠程式碼。
在 initMap() 函式中初始化位置提供者。
在 initMap() 函式中初始化地圖檢視。檢視畫麵包含地圖。
將自訂內容移至地圖檢視初始化的回呼函式。
將位置程式庫加入 API 載入器。

使用排程工作的地圖替換範例

以下範例顯示如何使用已初始化的現有地圖為已排定的工作用途建立位置提供工具物件程式碼很類似用於隨選行程用途，但您可以使用 FleetEngineVehicleLocationProvider 而非 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.
        -->
