Google放置API Android resultCallback未启动

Question

我使用的是Google Places API for Android，但似乎无法从PendingResult中获取ResultCallback来激发。这里是我的代码（除了在对话框中之外，与https://github.com/googlesamples/android-play-places/tree/master/placeComplete的示例代码基本相同）

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();
            }
        });
    }
});

我也遇到了同样的问题，因为我缺少允许API访问Google基于Web的服务的权限

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