나는 튜토리얼을 따라 왔으며 비슷한 스레드를 여기에서 읽었지만 FXML을 사용할 때 똑같은 것을 표현하기 위해 애 쓰고있다.MP3 시간 경과.
본질적으로 나는 timeText에서 매 초마다 업데이트 할 경과 시간을 얻으려고합니다.
누구든지 올바른 방법으로이 작업을 수행 할 수 있습니다.
아래에서 내 컨트롤러 클래스에 대한 코드를 볼 수 있습니다. 맨발로, 나는 자신의 대기열도 만들었습니다.

레이블 텍스트를 미디어 플레이어의 [현재 시간 속성] (http://docs.oracle.com/javase/8/javafx/api/javafx/scene/media/MediaPlayer.html#currentTimeProperty)에 바인딩하기 만하면됩니다. –
감사합니다. 내가 집에 갈 때 나는 한 번 살펴볼 것이다. –
시스템 출력으로 작업하고 있습니다. 나는 전체 슬라이더를 작업 한 후에이 문제에 대한 내 자신의 대답을 할 것입니다. –
