設定地圖樣式

選取平台: Android iOS JavaScript

本文件將說明如何自訂地圖的外觀和風格,以及控管資料顯示和檢視區選項。您可以選擇下列其中一種操作方式:

  • 使用雲端式地圖樣式設定
  • 直接在程式碼中設定地圖樣式選項

使用雲端式地圖樣式設定設定地圖樣式

使用雲端式地圖樣式設定,自訂地圖元件的外觀與風格。您可以在 Google Cloud 控制台上,為使用 Google 地圖的任何應用程式建立及編輯地圖樣式,完全不必變更程式碼。詳情請參閱「雲端式地圖樣式設定」。

ConsumerMapViewConsumerMapFragment 類別都支援雲端式地圖樣式設定。如要使用雲端式地圖樣式設定,請確認所選的地圖轉譯器為 LATEST。以下各節將舉例說明如何在專案中使用雲端地圖樣式。

ConsumerMapView

如要在 ConsumerMapView 中使用雲端地圖樣式,請在 GoogleMapOptions 上設定 mapId 欄位,然後將 GoogleMapOptions 傳遞至 getConsumerGoogleMapAsync(ConsumerMapReadyCallback, Fragment, GoogleMapOptions)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 ConsumerMapFragment 中使用雲端式地圖樣式設定的方式有兩種:

  • 使用 XML 的靜態方式。
  • 使用 newInstance 動態設定。

使用 XML 的靜態

如要在 ConsumerMapFragment 中使用雲端式地圖樣式,請將 map:mapId XML 屬性與指定的 mapId 一起新增。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 動態執行

如要在 ConsumerMapFragment 中使用雲端式地圖樣式搭配 newInstance,請在 GoogleMapOptions 上設定 mapId 欄位,並將 GoogleMapOptions 傳遞至 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 消費者行程分享地圖,請在建立 JourneySharingMapView 時指定 mapId 和其他 mapOptions

以下範例說明如何套用含有地圖 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.
});

直接在程式碼中設定地圖樣式

您也可以在建立 JourneySharingMapView 時設定地圖選項,藉此自訂地圖樣式。以下範例說明如何使用地圖選項為地圖設定樣式。如要進一步瞭解可設定的地圖選項,請參閱 Google Maps JavaScript API 參考資料中的 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" }
        ]
      }
    ]
  }
});

在地圖上顯示資訊

使用 InfoWindow 顯示車輛或位置標記的其他資訊。詳情請參閱 InfoWindow 的說明。

以下範例說明如何建立 InfoWindow 並將其附加至車輛標記:

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();

停用自動調整功能

您可以停用自動調整功能,停止讓地圖自動將可視區域調整至車輛和預估路線。以下範例說明如何在設定行程分享地圖檢視畫面時,停用自動調整功能。

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,
  ...
});
