Карты Google не отображаются во фрагменте

/ 17 октября 2019

Я прошу прощения, если я публикую вопрос, который похож на многие другие, но у каждого из них есть различные реализации карты Google, и попробовать их все означает полностью сломать мой код, и так как я новичок в разработке Android, яЯ бы предпочел не рисковать, если вы поможете мне выяснить, что не так с моей картой. Спасибо.

Когда я запускаю свое приложение, я получаю следующее: enter image description here

Это мой Gradle.build (приложение):

В вашем фрагменте используйте MapView: 

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".HomeFragment">

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

</RelativeLayout>

В вашем фрагменте используйте: 

  public class HomeFragment extends Fragment implements OnMapReadyCallback {

    private GoogleMap mMap;
    private MapView mMapView;

    @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            // Inflate the layout for this fragment
            View rootView = inflater.inflate(R.layout.fragment_home, container, false)

             /*
             * Configure Mapview and sync to google map.
             */
            mMapView = rootView.findViewById(R.id.mapView);
            mMapView.onCreate(savedInstanceState);
            mMapView.getMapAsync(this);
            mMapView.onResume(); // needed to get the map to display immediately

             //your code
            return rootView;
    }

    @Override
        public void onMapReady(GoogleMap googleMap) {
            this.mMap = googleMap;
        }
    }

Это будет работать нормально. Также проверьте ключ карты и интернет-соединение.

Что касается вашего кода, я не обнаружил никакой ошибки, но согласно вашему скриншоту, похоже, что ваше интернет-соединение пропущено, так что вы можете, пожалуйста, с правильным интернет-соединением и проверить его в первую очередь.
