如何在Android Studio中的Google Maps中为特定位置添加标记？

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

<com.google.android.gms.maps.MapView
    android:id="@+id/mapView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

private MapView mapView;

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

    mapView = findViewById(R.id.mapView);
    mapView.onCreate(savedInstanceState);
    mapView.onResume();
}

@Override
public void onResume() {
    super.onResume();
    mapView.getMapAsync(new OnMapReadyCallback() {
        @Override
        public void onMapReady(GoogleMap googleMap) {
            LatLng location = new LatLng(latitude, longitude);
            googleMap.addMarker(new MarkerOptions().position(location).title("Marker Title"));
            googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(location, 12));
        }
    });
}

@Override
public void onDestroy() {
    super.onDestroy();
    mapView.onDestroy();
}
