AutocompleteSupportFragment 不起作用消息“无法加载搜索结果”Android

Question

我在使用 AutocompleteSupportFragment 查找地点时遇到问题，因为它没有显示任何结果并且我收到错误消息。 我已经输入了使用的新代码，因为他们要求我提供 Google 控制台密钥，但它仍然无法正常工作。 这是我的代码 我没有密码限制，不知道是不是这个问题。

Places API 已启用

谢谢。

MainActivity.java

public class MainActivity extends AppCompatActivity {


PlacesClient placesClient;
List<Place.Field> placesFields= Arrays.asList(Place.Field.ID,Place.Field.NAME,Place.Field.ADDRESS);
AutocompleteSupportFragment places_fragment;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    initPlaces();
    setUpPlacesAutocomplete();

}


private void initPlaces() {

    Places.initialize(this,getString(R.string.places_api_key));
    placesClient=Places.createClient(this);


}

private void setUpPlacesAutocomplete() {


    places_fragment =(AutocompleteSupportFragment)getSupportFragmentManager()
            .findFragmentById(R.id.places_autocompletar);
    places_fragment.setPlaceFields(placesFields);
    places_fragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
        @Override
        public void onPlaceSelected(@NonNull Place place) {

            Toast.makeText(MainActivity.this, ""+place.getName(), Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onError(@NonNull Status status) {

            Toast.makeText(MainActivity.this, ""+status.getStatusMessage(), Toast.LENGTH_SHORT).show();

        }
    });




}

Please try with below code

private static final int AUTOCOMPLETE_REQUEST_CODE = 101;

 /*-- initializing Places API --**/
    if (!Places.isInitialized()) {
        Places.initialize(getActivity(), getActivity().getResources().getString(R.string.google_map_key));
    }

  /*-- function to open address search activity --**/
public void createAutoCompleteIntent() {
    if (getActivity() != null) {
        List<Place.Field> fields = Arrays.asList(Place.Field.ID, Place.Field.NAME, Place.Field.LAT_LNG, Place.Field.ADDRESS);
        Intent intent = new Autocomplete.IntentBuilder(
                AutocompleteActivityMode.FULLSCREEN, fields)
                .build(getActivity());
        startActivityForResult(intent, AUTOCOMPLETE_REQUEST_CODE);
