En esta página, se explica con un ejemplo cómo agregar un mapa 3D básico a una app para Android con el SDK de Maps 3D para Android. En las instrucciones de esta página, se da por sentado que ya completaste los pasos de la página Configuración y que tienes lo siguiente:
Un proyecto de Google Cloud con el SDK de Maps 3D para Android habilitado
Una clave de API configurada para usar con el SDK de Mapas 3D para Android
Un proyecto de Android Studio configurado para usar con el SDK de Mapas 3D para Android
Para obtener más información sobre estos requisitos previos, consulta Configuración.
Parte 1: Actualiza el archivo de diseño (activity_main.xml) para agregar el componente Map3DView
El componente Map3DView es la vista que renderiza el mapa en 3D dentro de la app.
En los siguientes pasos, se agrega el componente y se configura el estado inicial del mapa, incluida la posición de la cámara y los atributos relacionados:
Abre el archivo de diseño de tu actividad principal, que suele ubicarse en app/src/main/res/layout/activity_main.xml.
En el elemento raíz ConstraintLayout (o tu elemento de diseño raíz), agrega el espacio de nombres XML map3d:
En los siguientes pasos, se inicializa el componente Map3DView agregado al archivo activity_main.xml en la Parte 1 y se administran los eventos del ciclo de vida del componente:
Abre el archivo MainActivity.kt, que suele encontrarse en app/src/main/java/com/example/yourpackagename/MainActivity.kt.
Agrega las importaciones necesarias para el SDK de Maps 3D para Android:
En el método onCreate, después de setContentView(...) y el bloque ViewCompat.setOnApplyWindowInsetsListener, inicializa map3DView, llama a su método de ciclo de vida onCreate y solicita el mapa de forma asíncrona:
Anula el método onMap3DViewReady. Esta devolución de llamada se activa cuando el mapa está listo para utilizarse:
overridefunonMap3DViewReady(googleMap3D:GoogleMap3D){// Interact with the googleMap3D object herethis.googleMap3D=googleMap3D// You can now make calls to the googleMap3D object, e.g.,// googleMap3D.cameraController.flyTo(camera { ... })}
Reenvía los eventos de ciclo de vida de tu Activity al Map3DView agregando las siguientes anulaciones al MainActivity:

The instructions on this page assume that you\nhave already completed the steps in the\n[Setup](/maps/documentation/maps-3d/android-sdk/setup) page and have the\nfollowing:\n\n- A Google Cloud project with the Maps 3D SDK for Android enabled\n- An API key configured to use with the Maps 3D SDK for Android\n- An Android Studio project set up to use with the Maps 3D SDK for Android\n\nFor more information about these prerequisites, see\n[Setup](/maps/documentation/maps-3d/android-sdk/setup).\n\nPart 1: Update Layout File (`activity_main.xml`) to add the `Map3DView` component\n---------------------------------------------------------------------------------\n\nThe `Map3DView` component is the view that renders the 3D map within the app.\nThe following steps add the component and configure the initial state of the\nmap, including the camera position and related attributes:\n| **Note:** The steps in this section assume that you have created and configured your Android Studio project using the process described in [Setup](/maps/documentation/maps-3d/android-sdk/setup), or that you have added a new View activity to an existing project. If you create a new Android Studio project without adding a View activity, your project won't contain an `activity_main.xml` file.\n\n1. Open your main activity's layout file, which is usually located at\n `app/src/main/res/layout/activity_main.xml`.\n\n2. In the root `ConstraintLayout` (or your root layout element), add the `map3d`\n XML namespace:\n\n xmlns:map3d=\"http://schemas.android.com/apk/res-auto\"\n\n3. Delete the default `\u003cTextView\u003e` that displays \"Hello World!\".\n\n4. Add the `Map3DView` component to your layout. You can customize the camera\n position and other attributes:\n\n \u003c?xml version=\"1.0\" encoding=\"utf-8\"?\u003e\n \u003candroidx.constraintlayout.widget.ConstraintLayout xmlns:android=\"http://schemas.android.com/apk/res/android\"\n xmlns:app=\"http://schemas.android.com/apk/res-auto\"\n xmlns:map3d=\"http://schemas.android.com/apk/res-auto\" xmlns:tools=\"http://schemas.android.com/tools\"\n android:id=\"@+id/main\"\n android:layout_width=\"match_parent\"\n android:layout_height=\"match_parent\"\n tools:context=\".MainActivity\"\u003e\n\n \u003ccom.google.android.gms.maps3d.Map3DView\n android:id=\"@+id/map3dView\"\n android:layout_width=\"match_parent\"\n android:layout_height=\"match_parent\"\n map3d:mode=\"hybrid\"\n map3d:centerLat=\"38.544012\"\n map3d:centerLng=\"-107.670428\"\n map3d:centerAlt=\"2427.6\"\n map3d:heading=\"310\"\n map3d:tilt=\"63\"\n map3d:range=\"8266\"\n map3d:roll=\"0\"\n map3d:minAltitude=\"0\"\n map3d:maxAltitude=\"1000000\"\n map3d:minHeading=\"0\"\n map3d:maxHeading=\"360\"\n map3d:minTilt=\"0\"\n map3d:maxTilt=\"90\"\n app:layout_constraintBottom_toBottomOf=\"parent\"\n app:layout_constraintEnd_toEndOf=\"parent\"\n app:layout_constraintStart_toStartOf=\"parent\"\n app:layout_constraintTop_toTopOf=\"parent\" /\u003e\n \u003c/androidx.constraintlayout.widget.ConstraintLayout\u003e\n\nPart 2: Update MainActivity.kt\n------------------------------\n\nThe following steps initialize the `Map3DView` component added to the\n`activity_main.xml` file in Part 1 and manage component lifecycle events:\n\n1. Open your `MainActivity.kt` file, which is usually located at\n `app/src/main/java/com/example/yourpackagename/MainActivity.kt`.\n\n2. Add the necessary imports for the Maps 3D SDK for Android:\n\n import com.google.android.gms.maps3d.GoogleMap3D\n import com.google.android.gms.maps3d.Map3DView\n import com.google.android.gms.maps3d.OnMap3DViewReadyCallback\n\n3. Modify the `MainActivity` class to implement `OnMap3DViewReadyCallback`:\n\n class MainActivity : AppCompatActivity(), OnMap3DViewReadyCallback {\n\n4. Declare variables for `Map3DView` and `GoogleMap3D`:\n\n private lateinit var map3DView: Map3DView\n private var googleMap3D: GoogleMap3D? = null\n\n5. In the `onCreate` method, after `setContentView(...)` and the\n `ViewCompat.setOnApplyWindowInsetsListener` block, initialize the `map3DView`,\n call its `onCreate` lifecycle method, and request the map asynchronously:\n\n override fun onCreate(savedInstanceState: Bundle?) {\n super.onCreate(savedInstanceState)\n enableEdgeToEdge()\n setContentView(R.layout.activity_main)\n ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.main)) { v, insets -\u003e\n val systemBars = insets.getInsets(WindowInsetsCompat.Type.systemBars())\n v.setPadding(systemBars.left, systemBars.top, systemBars.right, systemBars.bottom)\n insets\n }\n\n map3DView = findViewById(R.id.map3dView)\n map3DView.onCreate(savedInstanceState)\n map3DView.getMap3DViewAsync(this)\n }\n\n6. Override the `onMap3DViewReady` method. This callback is triggered when the\n map is ready to be used:\n\n override fun onMap3DViewReady(googleMap3D: GoogleMap3D) {\n // Interact with the googleMap3D object here\n this.googleMap3D = googleMap3D\n // You can now make calls to the googleMap3D object, e.g.,\n // googleMap3D.cameraController.flyTo(camera { ... })\n }\n\n7. Forward lifecycle events from your Activity to the `Map3DView` by adding the\n following overrides to the `MainActivity`:\n\n override fun onStart() {\n super.onStart()\n map3DView.onStart()\n }\n\n override fun onResume() {\n super.onResume()\n map3DView.onResume()\n }\n\n override fun onPause() {\n map3DView.onPause()\n super.onPause()\n }\n\n override fun onStop() {\n map3DView.onStop()\n super.onStop()\n }\n\n override fun onDestroy() {\n map3DView.onDestroy()\n super.onDestroy()\n }\n\n override fun onSaveInstanceState(outState: Bundle) {\n super.onSaveInstanceState(outState)\n map3DView.onSaveInstanceState(outState)\n }\n\n override fun onLowMemory() {\n super.onLowMemory()\n map3DView.onLowMemory()\n }\n\nPart 3: Sync Gradle and Run\n---------------------------\n\nNow that you've updated your app's layout and activity, you can build and run\nthe app to see the 3D map view.\n\n1. To sync your project with Gradle, select **File \\\u003e Sync Project with Gradle Files.**\n\n2. To build and run your app on an emulator or a physical device, select\n **Run \\\u003e Run**.\n\nIf everything is configured correctly, you should see a 3D map displayed in your\napp, centered near the coordinates specified in your `activity_main.xml`.\n\nNext steps\n----------\n\nNow that you've added a basic 3D map to your app, you can explore more advanced\nfeatures of the Maps 3D SDK for Android, such as\n[camera path animations](/maps/documentation/maps-3d/android-sdk/custom-camera-paths),\n[3D markers](/maps/documentation/maps-3d/android-sdk/add-a-marker), or\n[polygons](/maps/documentation/maps-3d/android-sdk/add-polygons)."]]
