Question

我可能接近这个错误，但我需要找出如何停止循环javax.sound.sampled剪辑。我有9种不同的声音。当用户按下增大幅度按钮时，我想要播放不同的声音。目前我正在调用playSound方法，每次单击按钮并且它正在工作，但是它不会停止已经播放的声音。声音只是相互影响。

当用户按下按钮时，有没有办法关闭所有现有声音？

这是我的playSound代码：

    public void playSound(){
    try {
        audio = AudioSystem.getAudioInputStream(soundFile[activeSound]);
        clip = AudioSystem.getClip();
        clip.open(audio);
        clip.start();
        clip.loop(Clip.LOOP_CONTINUOUSLY);           
    }

    catch (IOException ex){
        System.out.println("Sorry but there has been a problem reading your file.");
        ex.printStackTrace();
    }

    catch (UnsupportedAudioFileException ex1){
        System.out.println("Sorry but the audio file format you are using is not supported.");
        ex1.printStackTrace();
    }

    catch (LineUnavailableException ex2){
        System.out.println("Sorry but there are audio line problems.");
        ex2.printStackTrace();
    } 
}

我已经在这两天了，这让我很生气。任何帮助将不胜感激。

您想要的是停止播放所有现有剪辑。这可以使用Dataline.stop()方法完成。您所需要的只是能够访问所有现有剪辑。以下是我的建议。请注意，我只使用一个引用链接到当前循环剪辑。如果您有多个，请使用ArrayList<Clip>而不是仅使用一个。

private Clip activeClip;
public void playSound(){
    activeClip.stop();
    try {
        audio = AudioSystem.getAudioInputStream(soundFile[activeSound]);
        clip = AudioSystem.getClip();
        clip.open(audio);
        clip.start();
        clip.loop(Clip.LOOP_CONTINUOUSLY);
        activeClip = clip;
    }

    catch (IOException ex){
        System.out.println("Sorry but there has been a problem reading your file.");
        ex.printStackTrace();
        }

    catch (UnsupportedAudioFileException ex1){
        System.out.println("Sorry but the audio file format you are using is not     supported.");
        ex1.printStackTrace();
    }

    catch (LineUnavailableException ex2){
        System.out.println("Sorry but there are audio line problems.");
        ex2.printStackTrace();
    } 
}
