1. 바로가기 메뉴 (NavigationDrawer)

화면의 좌상단에 위치한 모양의 아이콘을 눌렀을 때 나타나는 화면이며, NavigationDrawer라는 클래스로 제공된다.

이 메뉴는 여러 개의 화면에서 공통으로 적용되어 빠르게 메뉴 기능에 접근할 수 있다.


안드로이드 스튜디오에서 프로젝트 생성시, 

[File] - [New] - [New Project] - Empty Activity 가 아닌 Navigation Drawer Activity 를 선택한다.

1. 뷰페이저 (ViewPager)

뷰페이저는 좌우 스크롤을 통해 여러 개의 화면을 전환할 수 있도록 만든 것이다.

뷰페이저 안에 들어가는 각각의 화면은 프래그먼트로 만들 수 있고, 어댑터를 사용하여 프래그먼트들을 관리할 수 있다.

프래그먼트를 하나의 아이템으로 관리하는 어댑터는 SDK에서 제공되는 어댑터인 FragmentStatePagerAdapter 클래스를 사용한다.
