Привет, я пытаюсь создать карту во фрагменте, я следовал онлайн-учебнику, который должен был быть в действии, и я столкнулся с проблемой.Я искал везде, и я не могу найти решение.
Когда я пытаюсь скомпилировать в Android Studio, это дает мне ошибку в моей карте "инициализировать строку ошибка:
incompatible types: Fragment cannot be converted to SupportMapFragment"
Ошибкавозникает на initMap():
строка:
SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map);
Эта проблема возникла после того, как я изменил свой импорт с import android.support.v4.app.Fragment; на import android.app.Fragment; (который я должен сохранить из-за других ошибок приложения)
Вот мой фрагмент кода:
public class MapFragment extends Fragment implements OnMapReadyCallback
{
private static final String TAG = "MapFragment";
private Boolean LocationPermissionsGranted = false; //boolean for location method
private GoogleMap Map;
private static final int ERROR_REQUEST = 69; //error code relates to isservicesOK method
private static final String FINE_LOCATION = Manifest.permission.ACCESS_FINE_LOCATION;
private static final String COURSE_LOCATION = Manifest.permission.ACCESS_COARSE_LOCATION;
private static final int LOCATION_PERMISSION_CODE = 1234;
public MapFragment() {
// Required empty public constructor
}
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate( savedInstanceState );
//TODO: Instead of hardcoding the title perhaps take the user name from somewhere?
// Note the use of getActivity() to reference the Activity holding this fragment
getActivity().setTitle( "YOUR CLINICS" );
isServicesOK();
getLocationPermission();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
ButterKnife.bind( getActivity() );
return inflater.inflate( R.layout.fragment_map, container, false );
}
@Override

}
