MapboxFragment.java

public class MapBoxFragment extends Fragment {

    private MapView mapView = null;

    View convertView;


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        convertView = inflater.inflate(R.layout.fragment_map, null);

        mapView = (MapView) convertView.findViewById(R.id.altMapView);
        mapView.setStyle(Style.MAPBOX_STREETS);
        mapView.setCenterCoordinate(new LatLng(0, 0));

        // Show user location (purposely not in follow mode)
        mapView.setMyLocationEnabled(true);
        return convertView;
    }
}

在 Activity 中使用相同的布局时它正在工作。

当我更新我的 Mapbox SDK for android 时，我遇到了这个问题。我在初始化 MapView 后通过添加 mapView.onCreate(savedInstanceState) 解决了这个问题。希望这会有所帮助。
