내가 만든 음악을 사용하여 플레이어 JavaFX. 그러나 나는지 이해할 수 있는 방법을 내가 알 수 있습니다 기간의 노래 나는 현재 재생됩니다.
편집: 가가 다음 줄을 내 코드는 이제 노래 시간을 볼 수 있습니다. 그러나 때,나는 플레이 다음 노래,노래 시간은 보이지 않습니다. 여기에 줄을 추가 코드:
mediaPlayer.currentTimeProperty().addListener(new TimeListener());
TimeListener = new ChangeListener<Duration>()
{
@Override public void changed(ObservableValue<? extends Duration> o, Duration oldVal, Duration newVal)
{
//now newVal is of Duration class
}
};
}
public class TimeListener implements ChangeListener {
public void changed(ObservableValue o, Object oldVal, Object newVal) {
//Update time display with MediaPlayer's current time:
playTime.setText(newVal.toString());
}
}
여기에는 나의 코드를 만들의 음악 플레이어:

가 읽고 오라클 문서(https://docs.oracle.com/javase/8/javafx/media-tutorial/playercontrol.htm다)및 이디(https://www.youtube.com/watch?v=-D2OIekCKes한)를 만들의 음악 플레이어입니다.
나는 감사하게 될 것이라고 어떤 도움이됩니다. 사전에 감사합니다!
