Google Places API Android resultCallback未触发

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

I'm using the Google Places API for Android and I can't seem to get a resultCallback from a PendingResult to fire. Here's my code (essentially identical to the sample code to https://github.com/googlesamples/android-play-places/tree/master/PlaceComplete except in a Dialog)

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();
            }
        });
    }
});
