Chap6. 인터페이스 기초03 - Custom View, Toast, Beep, Vibration, etc
패키지명 : Exam01

• 해야할 것

1. btnToast를 누르면 자신의 이름을 토스트로 출력
2. btnSound를 누르면 dingdong 사운드 출력
3. btnVibration을 누르면 1초간 진동

1. btnToast를 누르면 자신의 이름을 토스트로 출력

//onClick 메소드
case R.id.btnToast:
	Toast.makeText(this, "SEIN", Toast.LENGTH_SHORT).show();
	break;

2. btnSound를 누르면 dingdong 사운드 출력

//onClick 메소드
case R.id.btnSound:
	SoundPool soundPool = new SoundPool(1, STREAM_MUSIC, 0);
	int sound = soundPool.load(this, R.raw.dingdong, 1);
	soundPool.play(sound, 1, 1, 0, 0, 1);
	break;

3. btnVibration을 누르면 1초간 진동

//onClick 메소드
case R.id.btnVibration:
	Vibrator vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
	vibrator.vibrate(1000);
	break;

심화) 다양한 진동 패턴으로 변경시켜 볼 것

//onClick 메소드
case R.id.btnVibration:
	Vibrator vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
	vibrator.vibrate(new long[] {100, 50, 200, 50}, 0);
	break;

//짝수 인덱스 = 대기시간, 홀수 인덱스 = 진동 시간
//Manifest에 퍼미션 부여 잊지 말기
