How to hide zoom elements and find me in Yandex maps?

Question

Android

Hey!

final MapView MapView = (MapView) findViewById(R.id.map);
    // Получаем MapController
    MapController cMapController = MapView.getMapController();

    // Включаем элементы интерфейса, контролирующие зум
    MapView.showBuiltInScreenButtons(true);

I need to hide these elements after a long press on the map

case MapEvent.MSG_LONG_PRESS:
                textView.setText("MSG_LONG_PRESS");
                mMapController = MapView.getMapController();
                MapView.showBuiltInScreenButtons(false);
                break;

So swears on false
Most likely I do not so. If anyone knows, tell me
