java - Google Places 自动完成 API 2019

Question

我已经尝试了好几天了，但就是找不到使用 Google 地点自动完成 API 的解决方案。我找到的所有方法大部分都是旧版本的。现在，随着 Android 版 Places SDK(在 Google Play Services 16.0.0 中)的 Google Play Services 版本被弃用，我似乎找不到可用的更新代码。我在网上找到的所有解决方案都不适合我，我什至无法理解发生了什么。有人可以详细说明一下使用 Google Place Autocomplete API 的新方法的代码吗？

这就是我到目前为止所做的。

public class SearchAndFilter extends AppCompatActivity {
    String TAG = "placeautocomplete";
    TextView txtView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_search_and_filter);
        txtView = findViewById(R.id.txtView);

        // Initialize Places.
        Places.initialize(getApplicationContext(), "MY_KEY");
        // Create a new Places client instance.
        PlacesClient placesClient = Places.createClient(this);

        // Initialize the AutocompleteSupportFragment.
        AutocompleteSupportFragment autocompleteFragment = (AutocompleteSupportFragment)
                getSupportFragmentManager().findFragmentById(R.id.autocomplete_fragment);

        // Specify the types of place data to return.
        autocompleteFragment.setPlaceFields(Arrays.asList(Place.Field.ID, Place.Field.NAME));

        // Set up a PlaceSelectionListener to handle the response.
        autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
            @Override
            public void onPlaceSelected(Place place) {
                // TODO: Get info about the selected place.
                txtView.setText(place.getName()+","+place.getId());
                Log.i(TAG, "Place: " + place.getName() + ", " + place.getId());
            }

            @Override
            public void onError(Status status) {
                // TODO: Handle the error.
                Log.i(TAG, "An error occurred: " + status);
            }
        });
    }
}

当我运行上面的代码时，搜索栏带有谷歌水印，但当我输入内容时，搜索栏就会关闭。我不知道为什么。

只需在Oncreate()中调用该函数即可；

    /**
 * Sets up the autocomplete fragment to show place details when a place is selected.
 */
private void setupAutoCompleteFragment() {
    PlaceAutocompleteFragment autocompleteFragment = (PlaceAutocompleteFragment)
            getFragmentManager().findFragmentById(R.id.place_autocomplete_fragment);

    AutocompleteFilter typeFilter = new AutocompleteFilter.Builder()
            .setTypeFilter(Place.TYPE_COUNTRY).setCountry("IN")

            .build();
    autocompleteFragment.setFilter(typeFilter);

    autocompleteFragment.setHint(getResources().getString(R.string.search_stadium_court_area));
    autocompleteFragment.searchIcon.setVisibility(View.GONE);
    autocompleteFragment.input.setTextSize(10f);

    autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {


        @Override
        public void onPlaceSelected(Place place) {
            showPlace(getString(R.string.place_autocomplete_search_hint), place);

        }

        @Override
        public void onError(Status status) {
            showResponse("An error occurred: " + status);
        }
    });
}


    private void showPlace(String source, Place place) {
    locationSelect = AppConstants.LOCATION_SELECTED_ONITEMCLICK;

    PlaceBean placeBean = new PlaceBean();


    placeBean.setAddress(String.valueOf(place.getAddress()));
    placeBean.setLatitude(String.valueOf(place.getLatLng().latitude));
    placeBean.setLongitude(String.valueOf(place.getLatLng().longitude));
    placeBean.setName((String) place.getName());
    placeBean.setCityname(cityName);

    Intent intent = new Intent();
    intent.putExtra("location", placeBean);
    setResult(RESULT_OK, intent);
    finish();

}
