드래그 바(SeekBar)
seekbar 는 Progressbar 의 하위 클래스 입 니 다.
몇 가지 방법 이 있 습 니 다.
SeekBar.getProgress()드래그 바 현재 값 가 져 오기
setOnSeekBarChangeListener()방법,드래그 바 값 변화 이 벤트 를 처리 하고 SeekBar.OnSeekBarChangeListener 인 스 턴 스 를 매개 변수 로 전송 합 니 다.

설명:SeekBarActivity 가 생 성 되 었 을 때 seekBar 에 감청 이 벤트 를 등록 합 니 다.또한 refresh()방법 을 호출 하여 드래그 바 의 진도 값 을 자동 으로 새로 고 칩 니 다.드래그 바 의 진도 값 이 바 뀌 었 을 때 seekBar 상부 TextView 의 내용 을 수정 합 니 다.
