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」。
ConsumerMapView 和 ConsumerMapFragment 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) 或 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 ConsumerMapFragments 中使用雲端式地圖樣式設定的方式有兩種：
- 使用 XML 靜態。
- 使用
newInstance動態。
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 中搭配 newInstance 使用雲端式地圖樣式設定，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 消費者行程共用地圖，請在建立 JourneySharingMapView 時指定 mapId 和任何其他 mapOptions。
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。
下例說明如何建立 InfoWindow 並附加至車輛標記：
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();
停用自動合框功能
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,
...
});
