You can set a marker's altitude by setting the
altitudeMode
property to one of the
following values:
ABSOLUTERELATIVE_TO_GROUNDCLAMP_TO_GROUNDRELATIVE_TO_MESH
The following code sample
demonstrates how to use each of the methods. To use this code sample, follow the instructions in
Setup and
Add a 3D map to your app to set
up your Android Studio project with a basic 3D map. Then, add the following code to the
MainActivity.kt file:
// Add imports
import com.google.android.gms.maps3d.model.latLngAltitude
...
// Add to the onMap3DViewReady method, after the googleMap3D object has been initialized
googleMap3D.setMapMode(Map3DMode.SATELLITE)
googleMap3D.setCamera(
