我正在尝试制作一个带有抽屉导航和 map fragment 的应用程序。我试图拥有一个自动完成 fragment ，但是当我搜索一个地方时，我只收到 name 和 id 属性。 像这样:

I/PLACE: Place{address=null, attributions=[], id=ChIJVXealLU_xkcRja_At0z9AGY, latLng=null, name=Amsterdam, openingHours=null, phoneNumber=null, photoMetadatas=null, plusCode=null, priceLevel=null, rating=null, types=null, userRatingsTotal=null, viewport=null, websiteUri=null}

这是我的 MapsFragment

public class MapsFragment extends Fragment implements OnMapReadyCallback, LocationListener {

MapView mapView;
GoogleMap nMap;

AutocompleteSupportFragment autocompleteFragment;
PlacesClient placesClient;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    final View rootView = inflater.inflate(R.layout.activity_maps, container, false);

    ...
    mapView = (MapView) rootView.findViewById(R.id.mapView);
    mapView.onCreate(savedInstanceState);
    mapView.getMapAsync(this);

}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    autocompleteFragment.onActivityResult(requestCode, resultCode, data);
}

...



@Override
public void onMapReady(GoogleMap googleMap) {
    Log.i("DEBUG", "onMapReady");

    nMap = googleMap;

    Context mContext = getActivity();
    if (mContext != null){
    Places.initialize(mContext, "*********MY API KEY*********");
    }else{
        Log.i("PLACE", "ERROR");
    }

    placesClient = Places.createClient(getActivity());

    autocompleteFragment = (AutocompleteSupportFragment)
            getChildFragmentManager().findFragmentById(R.id.place_autocomplete_fragment);


    autocompleteFragment.setPlaceFields(Arrays.asList(Place.Field.ID, Place.Field.NAME));

    autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
        @Override
        public void onPlaceSelected(@NonNull Place place) {
            Log.i("PLACE", place.toString());
            // Define a Place ID.
            //nMap.moveCamera(CameraUpdateFactory.newLatLng(place.getLatLng()));
            //nMap.animateCamera(CameraUpdateFactory.newLatLngZoom(place.getLatLng(), 12.0f));
        }

        @Override
        public void onError(@NonNull Status status) {
            Log.i("PLACE", status.toString());
        }
    });

    autocompleteFragment.setUserVisibleHint(true);
    autocompleteFragment.setHint("Select your city");


    if (ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_COARSE_LOCATION)
            == PackageManager.PERMISSION_GRANTED) {
        nMap.setMyLocationEnabled(true);
    } else {
        // Show rationale and request permission.
        Log.d(TAG, "error permission denied");
    }
}

这是我的 map.xml

...
<fragment
    android:id="@+id/place_autocomplete_fragment"
    android:name="com.google.android.libraries.places.widget.AutocompleteSupportFragment"
    android:layout_width="match_parent"
    android:layout_height="56dp" />

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

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

我将我的 API KEY 放在代码中(查看 map fragment )、googles_maps_api.xml 以及 gradle.properties

PLACES_API_KEY="MY API KEY"

这是我对谷歌地图的依赖

dependencies {
    ...
    implementation 'com.google.android.libraries.places:places:1.0.0'
}

我关注每个 steps用于激活我的 API KEY

我也尝试通过 android 限制来保护我的 KEY 但没有任何改变

我的计费系统已启用。

最佳答案

you didnt allow in setPlaceFields what do you want.for example i want latlang so i have added LAT_LNG. see below.

 autocompleteFragment.setPlaceFields(Arrays.asList(Place.Field.ID, Place.Field.NAME,Place.Field.LAT_LNG));

关于android - AutocompleteFragment 结果返回一个具有 null 属性的地方，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/54707679/
