Das folgende Codebeispiel zeigt, wie Sie eine Polylinie hinzufügen und sie im 3D-Raum positionieren, indem Sie die Methode addPolyline
aufrufen. Wenn Sie dieses Codebeispiel verwenden möchten, folgen Sie der Anleitung unter Einrichtung und 3D-Karte in Ihre App einfügen, um Ihr Android Studio-Projekt mit einer einfachen 3D-Karte einzurichten. Fügen Sie dann der Datei MainActivity.kt
den folgenden Code hinzu:
// Add imports
import com.google.android.gms.maps3d.model.latLngAltitude
...
// Add to the onMap3DViewReady method, after the googleMap3D object has been initialized
googleMap3D.setCamera(
