Question

我的代码与AppCompatActivity.onCreate()中的代码非常相似。我试图在片段而不是活动中做类似的事情。但是在Fragment.onCreateView()中，我在下面指定的行上得到了InvalidAccessTokenException。访问令牌从the Mapbox website生成，字符串MAPBOX_TOKEN被赋予其值。我做错了什么？

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

    View view = inflater.inflate(R.layout.individual, container, false);

    <set various TextViews and ImageViews>

    MapboxAccountManager.start(getActivity(), MAPBOX_TOKEN);

    MapView mapView = (MapView) view.findViewById(R.id.mapView); // create map
    mapView.setStyleUrl(Style.LIGHT); // set MapBox streets style

    mapView.getMapAsync(new OnMapReadyCallback() {
        @Override
        public void onMapReady(MapboxMap mapboxMap) {

            <set various things on mapboxMap>
        }
    });

    mapView.setClickable(true);

    mapView.onCreate(savedInstanceState); // com.mapbox.mapboxsdk.exceptions.InvalidAccessTokenException: 

    return view;
}

在致电MapboxAccountManager之前，您要对视图进行充气。它要么需要在代码中完成任何与Mapbox相关的操作（包括在XML中），要么更好的选择是在我们的testapp中完成add it to your application object。

onCreateView中的com.mapbox.mapboxsdk.exceptions.InvalidAccessTokenException
