How to get a property from an observablelist with multiple properties

Question

private final ObservableList<City> cityList = FXCollections.observableArrayList(city
        -> new Observable[]{
            city.cityNameProperty(),
            city.cityLonProperty(),
            city.cityLatProperty()});

public ObservableList<City> getCityList() {
    return cityList;
}

How can I retrieve the cityNameProperty from one object inside the observableArrayList for setting a listview?

I did

cityView.setItems(cityList.getCityList());

But this is setting the objects (city@59f..etc), whereas I need the properties of the objects.

Use a cell factory:

cityView.setCellFactory(lv -> new ListCell<City>() {
    @Override
    protected void updateItem(City city, boolean empty) {
        super.updateItem(city, empty);
        setText(empty ? null : city.getCityName());
    }
});
