Создание перетаскиваемой карты, например, uber application

Я следил за одной ссылкой, которая имеет код для создания карты, которую мы можем перетащить и получить текущее местоположение. Ссылка здесь. Как реализовать перетаскиваемую карту, например, uber android, Обновить с изменением местоположения

Я следил за всем кодом, но я не могу получить результат. Карта, которую мы можем перетащить, но не отображающая местоположение в текстовом режиме.

Может ли кто-нибудь помочь мне с этим?
