Configure a map | Maps SDK for Android

Select platform: Android iOS

This document describes how to configure a map that was added to an Android app using the Maps SDK for Android.

Overview

After you add a map to your app, you can configure the initial and runtime settings of the map. The initial settings need be configured based on whether you added the map container (SupportMapFragment or MapView) statically or dynamically. If the map container was added statically, you can configure the initial map settings in the layout file. If it was added dynamically, you can configure the initial settings in the OnCreate callback with a GoogleMapOptions object.

For details about adding a map container, see the Add a map.

The initial map settings include the following:

At runtime you can configure these settings and some addition settings by updating the GoogleMap object in the onMapReady callback. The additional settings are configured through the methods of the GoogleMap class, such as those that configure the traffic layer and map padding.

Example

In the example code below and the screenshot above, the map is configured with the following settings.

The initial settings are configured in the layout file:

The runtime settings:

Initial settings

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;

public class MainActivity extends AppCompatActivity implements OnMapReadyCallback {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);

    }

    // Update the map configuration at runtime.
    @Override
    public void onMapReady(GoogleMap googleMap) {
        // Set the map coordinates to Kyoto Japan.
        LatLng kyoto = new LatLng(35.00116, 135.7681);
        // Set the map type to Hybrid.
        googleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
        // Add a marker on the map coordinates.
        googleMap.addMarker(new MarkerOptions()
                .position(kyoto)
                .title("Kyoto"));
        // Move the camera to the map coordinates and zoom in closer.
        googleMap.moveCamera(CameraUpdateFactory.newLatLng(kyoto));
        googleMap.moveCamera(CameraUpdateFactory.zoomTo(15));
        // Display traffic.
        googleMap.setTrafficEnabled(true);

    }
}
Before you begin

Before you begin, you can set up a project and add a basic map through the following options:

Configure a map after adding it statically

This section describes how to set the initial state of the map if you added it statically to your layout file.

The Maps SDK for Android defines a set of custom XML attributes for a SupportMapFragment or a MapView that you can use to configure the initial state of the map directly from the layout file. The following attributes are defined:

In order to use these custom attributes within your layout file, it must include the following namespace declaration. You can choose any namespace, it doesn't have to be map:

xmlns:map="http://schemas.android.com/apk/res-auto"

You can then add the attributes with a map: prefix into your layout file.

The following layout file configures a SupportMapFragment object with custom map attributes. The same attributes can be applied to a MapView object as well.

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:map="http://schemas.android.com/apk/res-auto"
  android:name="com.google.android.gms.maps.SupportMapFragment"
  android:id="@+id/map"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  map:cameraBearing="112.5"
  map:cameraTargetLat="-33.796923"
  map:cameraTargetLng="150.922433"
  map:cameraTilt="30"
  map:cameraZoom="13"
  map:mapType="normal"
  map:mapColorScheme="dark"
  map:uiCompass="false"
  map:uiRotateGestures="true"
  map:uiScrollGestures="false"
  map:uiTiltGestures="true"
  map:uiZoomControls="false"
  map:uiZoomGestures="true"/>
Note: If you are using the Maps SDK for Android with a Google Maps Platform Premium Plan license, you must prefix each attribute with m4b_. For example, when specifying the map type attribute, use m4b_mapType instead of mapType. When specifying zoom controls, use m4b_uiZoomControls instead of uiZoomControls. Configure a map after adding it dynamically

This section describes how to set the initial state of the map if you added it to your app dynamically.

If you added a SupportMapFragment or MapView dynamically, then you can set the initial state of the map in a GoogleMapOptions object. The options available are the same options that are available in the layout file. You can create a GoogleMapOptions as follows:

Kotlin
val options = GoogleMapOptions()

      
Java
GoogleMapOptions options = new GoogleMapOptions();

      

And then configure it as follows:

Kotlin
options.mapType(GoogleMap.MAP_TYPE_SATELLITE)
    .compassEnabled(false)
    .rotateGesturesEnabled(false)
    .tiltGesturesEnabled(false)

      
Java
options.mapType(GoogleMap.MAP_TYPE_SATELLITE)
    .compassEnabled(false)
    .rotateGesturesEnabled(false)
    .tiltGesturesEnabled(false);

      

To apply these options when you are creating a map, do one of the following:

Localize your map

When you add a MapView or SupportMapFragment to your app, textual elements on the map are displayed in the appropriate language based on the user's device settings and location. You can restrict the languages used by your app to a subset of all supported languages, by adding a resConfigs item to your Gradle file. This is useful for stripping out unused languages, and also reduces your app's binary size. For example:

defaultConfig {
    resConfigs "en", "fr", "es", "zh", "de", "ja", "ru", "ko", "pt", "in"
}

Read more about localizing your Android app.

Set up the traffic layer

You can display traffic data on your map by enabling the traffic layer. You can enable and disable the traffic layer by calling the setTrafficEnabled() method, and you can determine whether the traffic layer is on by calling the isTrafficEnabled() method. The following screenshot displays a map with the traffic layer enabled.

Set the map type

To set the map type, call the setMapType method. For example, to display a satellite map:

Kotlin
// Sets the map type to be "hybrid"
map.mapType = GoogleMap.MAP_TYPE_HYBRID

      
Java
// Sets the map type to be "hybrid"
map.setMapType(GoogleMap.MAP_TYPE_HYBRID);

      

The following image compares the normal, hybrid and terrain map types:

Set up 3D buildings

Many cities, when viewed close up, will have 3D buildings visible, as viewable in the below picture of Vancouver, Canada. You can disable the 3d buildings by calling GoogleMap.setBuildingsEnabled(false).

Set up indoor map settings

At high zoom levels, the map shows floor plans for indoor spaces such as airports, shopping malls, large retail stores, and transit stations. These floor plans, called indoor maps, are displayed for the 'normal' and 'satellite' map types (GoogleMap.MAP_TYPE_NORMAL and GoogleMap.MAP_TYPE_SATELLITE). They are automatically enabled when the user zooms in, and they fade away when the map is zoomed out.

Deprecation notice: In a future release, indoor maps will only be available on the normal map type. From that future release, indoor maps will not be supported on satellite, terrain or hybrid maps. Even where indoor is not supported, isIndoorEnabled() will continue to return the value that has been set using setIndoorEnabled(), as it does now. By default, setIndoorEnabled is true. The release notes will let you know when indoor support becomes unavailable on those map types.

Here is a summary of the indoor maps capabilities in the API:

Set up map padding

This video shows an example of map padding.

A Google map is designed to fill the entire region defined by its container element, typically a MapView or SupportMapFragment. Several aspects of how the map appears and behaves are defined by the dimensions of its container:

You can add padding around the edges of the map using the GoogleMap.setPadding() method. The map will continue to fill the entire container, but text and control positioning, map gestures, and camera movements will behave as if it has been placed in a smaller space. This results in the following changes:

Padding can be helpful when designing UIs that overlap some portion of the map. In the following image, the map is padded along the top and right edges. Visible map controls and legal text will be displayed along the edges of the padded region, shown in green, while the map will continue to fill the entire container, shown in blue. In this example, you could float a menu over the right side of the map without obscuring map controls.

Note: As per the Google Maps Platform Terms of Service, your application must not remove or obscure the Google logo or copyright notices. Map padding lets you reposition these elements if necessary. If you display a custom UI at the bottom of the map, add padding to the bottom of the map so that the logo and legal notices will always be visible. Map color scheme

For maps of type normal and terrain, you can set the map color scheme dynamically to dark, light, or to use the current system setting. For example, you can darken or lighten the map color scheme based on the time of day or indoor or outdoor use of the device.

By default, the map uses light mode. The current system setting value is based on the device setting for UI_NIGHT_MODE_MASK.

Kotlin
mapFragment = SupportMapFragment.newInstance(GoogleMapOptions().mapColorScheme(MapColorScheme.DARK).mapId(mapId2))
Java
mapFragment = SupportMapFragment.newInstance(new GoogleMapOptions().mapColorScheme(MapColorScheme.DARK).mapId(mapId2));

You can toggle the color scheme using the GoogleMap.setMapColorScheme() method to set the current style to dark mode, light mode, or follow the system settings.

Kotlin
googleMap.setMapColorScheme(MapColorScheme.DARK)
googleMap.setMapColorScheme(MapColorScheme.LIGHT)
googleMap.setMapColorScheme(MapColorScheme.FOLLOW_SYSTEM)
Java
googleMap.setMapColorScheme(MapColorScheme.DARK);
googleMap.setMapColorScheme(MapColorScheme.LIGHT);
googleMap.setMapColorScheme(MapColorScheme.FOLLOW_SYSTEM);

To create custom light styles and dark styles for your maps, use cloud-based maps styling.

Note: Dark mode color scheme will only take effect on maps that don't use custom styling, or on maps that use cloud-based maps styling. Maps with JSON styling or maps using lite mode won't show the dark mode color scheme. Configure background color

When working in dark mode or switching between map views, it may be useful to configure the default map background color. This can be achieved by setting the map options backgroundColor property.

Kotlin
private val googleMapOptions: GoogleMapOptions =
    GoogleMapOptions().backgroundColor(Color.argb(255, 255, 0, 0));
Java
private GoogleMapOptions options = new GoogleMapOptions().backgroundColor(Color.argb(255, 255, 0, 0));
Note: Background color does not support opacity values.

You can also use cloud-based maps styling to configure the background color. The background color set in maps styling has a higher priority than the local background color. For more information, see Change the app background color for cloud-based maps styling.
