Карта Google с CollapsingToolbar и NestedScrollView

Я разрабатываю приложение, такое как UBER. Первая прокрутка пользовательского маркера на карте работала нормально. После этого я добавил NestedScrollView, как UBER. Но жест прокрутки карты конфликтует с поведением прокрутки AppBar. Я не знаю, что делать, пожалуйста, помогите мне.
