Question

我正在尝试将新的自动完成地点选择器从"com.google.android.gms:play-services"迁移到新的"com.google.android.libraries.places:places-compat:2.0.0"，并实现了SupportPlaceAutocompleteFragment。

一切正常，但是我得到的错误是：

"Place.Field" Cannot resolve symbol 'Field'

下面是我的代码：

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


//List<Place.Field> placeFields = Arrays.asList(Place.Field.ID, Place.Field.NAME);
// Specify the types of place data to return.
supportPlaceAutocompleteFragment.setPlaceFields(Arrays.asList(Place.Field.ID, Place.Field.NAME));

// Set up a PlaceSelectionListener to handle the response.
supportPlaceAutocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
    @Override
    public void onPlaceSelected(Place place) {
        // TODO: Get info about the selected place.
        Toast.makeText(MapsActivity.this, "Place: " + place.getName() + ", " + place.getId(), Toast.LENGTH_LONG).show();
        Log.i("", "Place: " + place.getName() + ", " + place.getId());
    }

    @Override
    public void onError(Status status) {
    }
});

supportPlaceAutocompleteFragment.setPlaceFields(Arrays.asList(Place.Field.ID, Place.Field.NAME));

您能帮我解决此错误吗？

"Place.Field" Cannot resolve symbol 'Field'

Answer 1

SupportPlaceAutocompleteFragment类为deprecated。请改用AutocompleteSupportFragment类。请参阅Google's migration guide和Place Autocomplete's guide。

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

//List<Place.Field> placeFields = Arrays.asList(Place.Field.ID, Place.Field.NAME);
// Specify the types of place data to return.
supportPlaceAutocompleteFragment.setPlaceFields(Arrays.asList(Place.Field.ID, Place.Field.NAME));

// Set up a PlaceSelectionListener to handle the response.
supportPlaceAutocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
    @Override
    public void onPlaceSelected(Place place) {
        Toast.makeText(MapsActivity.this, "Place: " + place.getName() + ", " + place.getId(), Toast.LENGTH_LONG).show();
        Log.i("", "Place: " + place.getName() + ", " + place.getId());
    }

    @Override
    public void onError(Status status) {
    }
});

supportPlaceAutocompleteFragment.setPlaceFields(Arrays.asList(Place.Field.ID, Place.Field.NAME));

希望这会有所帮助！

确保您导入了正确的Place类。

import com.google.android.libraries.places.api.model.Place;
