我希望获得波形声音的最大长度,播放曲目并使用JProgressBar显示其播放进度。这是我到目前为止所做的,但进度条没有更新。
Timer t = new Timer(1000,this);
private void playButtonMousePressed(java.awt.event.MouseEvent evt) {
// TODO add your handling code here:
try{
t.start();
String track = "tele";
music = new MusicFunctions(track);
// music.play(track);
int progressInit = 0;
final int len = music.trackLength();
int tLength = music.trackLength();
jProgressBar1.setMinimum(0);
jProgressBar1.setMaximum(len);
while(i<=len){
jProgressBar1.setValue(i);
jProgressBar1.repaint();
i++;
}
}catch(Exception e){
System.out.println(e);
}
}
答案 0 :(得分:-1)
请参阅SwingWorker文档;该示例甚至用于更新进度条:http://docs.oracle.com/javase/6/docs/api/javax/swing/SwingWorker.html。
