7강 ( 곡 기능 선택 구현 )

 

 

 

시작 버튼을 눌렀을 때 첫 번째 곡의 하이라이트 부분이 나오도록 편집

좌우 버튼을 클릭했을 때 곡이 바뀌도록 코드 추가 (Track 클래스 생성) / 해당 클래스는 하나의 곡의 정보를 담는 클래스

우클릭 - Source - Generate getter and setter ⇒ select all 클릭

 

 

 

생성자 생성 ⇒

Track이라는 클래스를 이용하여 새로운 변수를 만들어 줄때 참고한 값들을 그대로 초기화 해주는 기능을 수행하는 메서드

 

왼쪽 오른쪽 버튼을 눌렀을 때 버튼을 누른 trackList의 index 순서에 맞게

title Image, StartImage, Music 등을 출력하게 된다
