Question

我正在使用Google Places API for Android，而我似乎无法从resultCallback获取PendingResult。这是我的代码（基本上与https://github.com/googlesamples/android-play-places/tree/master/PlaceComplete的示例代码相同，除了在对话框中）

adapter = ((MainActivity) getActivity()).getAdapter();
googleApiClient = ((MainActivity) getActivity()).getGoogleApiClient();

final AutoCompleteTextView tvCity = new AutoCompleteTextView(getActivity());
tvCity.setAdapter(adapter);

tvCity.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        final PlacesAutoCompleteAdapter.PlaceAutocomplete item = adapter.getItem(position);
        final String placeId = String.valueOf(item.placeId);

        PendingResult<PlaceBuffer> placeResult = Places.GeoDataApi
                .getPlaceById(googleApiClient, placeId);
        placeResult.setResultCallback(new ResultCallback<PlaceBuffer>() {
            @Override
            public void onResult(PlaceBuffer places) {

            if (places.getStatus().isSuccess()) {
                    final Place place = places.get(0);
                    cityCoordinates = place.getLatLng();

                } else {
                    dialog.dismiss();
                    Toast.makeText(getActivity(), "There was an error, please try again", Toast.LENGTH_SHORT).show();
                    return;

                }
                dialog.getButton(AlertDialog.BUTTON_POSITIVE).setEnabled(true);
                places.release();
            }
        });
    }
});

Answer 1

我遇到了同样的问题，因为我错过了允许API访问Google基于网络的服务的权限

<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>

Answer 2

作为参考，对于访问此问题的任何人，请确保执行以下所有3个步骤：

将API密钥添加到应用清单

<application>
...
 <meta-data
    android:name="com.google.android.geo.API_KEY"
    android:value="YOUR_API_KEY"/>
</application>

然后在你的清单中加入@Alex Baker建议

<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>

并启用适用于Android的Google Places API 。 Google Places API是一种不同的API，您的来电将因Places AutoComplete status 9001

而失败

Google Places API Android resultCallback未触发
