다음 코드를 사용하여 다음과 같은 결과가있는 diffirent 위치에서 실행 해 보았습니다. 1) on에 배치하면 60 초로 재설정됩니다. 2) 배치시 재생이 버튼을 다시 누를 때까지 onResume에서 그런 다음 마지막 onPause 위치에서 카운트 다운이 시작 완벽하게 작동하는 것 같다 playAgain 방법에 배치하는 경우 3)는CountDownTimer의 전역 변수가 변경되지 않습니다

I 글로벌 VAR 세트를 가지고 카운트 다운 타이머 내에서 onFinnish에 재설정하는 것은 그것을 그러나 그것을 재설정해야한다고 가정 하지 않습니다.
감사
어떤 예외가 발생합니까? – Antoniossss
null 포인터입니다. 이유는 createTimer() 전에 countDownTimer.start()를 호출했기 때문입니다. 나는 그것이 어디 있는지 생각하기 위해 놀고있다. createTimer()가 onResume에 있으면 all이 작동하지만 다시 재생할 때 timeRemaining = l 값을 유지합니다. –
