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。
ConsumerMapView
和 ConsumerMapFragment
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) 或 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 mapId
的 map: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,
...
});
