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
使用云端地图样式设置自定义地图组件的外观和风格。您可以在 Google Cloud 控制台上为使用 Google 地图的任何应用创建和修改地图样式,而无需对代码进行任何更改。如需了解详情,请参阅云端地图样式设置。
ConsumerMapView
和 ConsumerMapFragment
类均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
。以下部分展示了如何在项目中使用基于云的 Google 地图样式的示例。
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
在 ConsumerMapFragment 中使用云端地图样式设置的方法有两种:
- 使用 XML 进行静态。
- 与
newInstance
动态关联。
使用 XML 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
若要将云端地图样式设置与 ConsumerMapFragment
中的 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,以自定义地图样式。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
您可以停用自动调整功能,让地图不再自动将视口调整为适合车辆和预计路线的大小。以下示例展示了如何在配置行程共享地图视图时停用自动适应功能。
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,
...
});
