Auto suggestion in text field with data from Google API

Question

I want to make an autocomplete text field with suggestions where data is from the Google API - updated after each new key pressed. For now, I have a method that downloads 5 suggestions and updates them when another key is pressed.

I've tried AutoCompleteTextField from Gluon, but it didn't work out well.

public class Controller {
    Weather weather = new Weather();
    GooglePlaces googlePlaces = new GooglePlaces();

    @FXML
    AutoCompleteTextField<String> autoCompleteTextField = new AutoCompleteTextField<>();

    @FXML
    public void setAutoComplete() throws IOException {
        ArrayList<String[]> places = googlePlaces.predictPlaces("New yo");

        autoCompleteTextField.setCompleter(s -> {
            ArrayList<String> autoplaces = new ArrayList<>();
            for (int i = 0; i < places.size(); i++) {
                autoplaces.add(places.get(i)[0]);
            }
            System.out.println("test");
            return autoplaces;
        });
    }
}

Here I tried to add 5 suggestions from "New yo" phase without updating after each new key, but it didn't work either as it doesn't show anything. "test" isnt printed in the console.

Seems to me that you need to call setCompleter() in a method called initialize():

public class Controller {

    @FXML
    public void initialize() {
        autoCompleteTextField.setCompleter(input -> {
            List<String[]> places = googlePlaces.predictPlaces(input);
            // ...
        });
    }
}
