我正在尝试通过 Google Maps SDK 实现自动完成功能。
我找到了一个指南，它使用 fragment 来显示您可以在其中搜索具有自动填充功能的地址的栏。
当我尝试将其集成到我的代码中时，我的问题就来了。我有这个在 fragment 中膨胀的 xml 文件。

此布局正在 fragment 中膨胀。这是我苦苦挣扎的代码。
public class ProfileTenantFragment extends Fragment {
private static final String TAG = "ProfileTenantFragment";
// Initialize Places.
Places.initialize(getApplicationContext(), getString(R.string.google_cloud_api_key));
// Create a new Places client instance.
PlacesClient placesClient = Places.createClient(getActivity());
// Initialize the AutocompleteSupportFragment.
AutocompleteSupportFragment autocompleteFragment = (AutocompleteSupportFragment)
getActivity().getSupportFragmentManager().findFragmentById(R.id.autocomplete_fragment);
autocompleteFragment.setTypeFilter(TypeFilter.CITIES);
// Specify the types of place data to return.
autocompleteFragment.setPlaceFields(Arrays.asList(Place.Field.ID, Place.Field.NAME));
我的 autocompleteFragment 总是空的。
