Я согласен с другим ответом здесь.Взгляните на документы.
Но для быстрого исправления:
Сначала импортируйте Android Design Library
implementation 'com.android.support:design:28.0.0'
У вас уже должны быть CardView и RecyclerViewбиблиотеки
implementation 'com.android.support:cardview-v7:28.0.0'
implementation 'com.android.support:recyclerview-v7:28.0.0'
Затем реализуйте этот код
