Question

我已经尝试过几十个教程，但我还没有能够让他们中的任何一个工作。我只想在我的应用程序的后台播放.wav文件。

Answer 1

public void playSound(String soundName)
 {
   try 
   {
    AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File(soundName).getAbsoluteFile());
    Clip clip = AudioSystem.getClip();
    clip.open(audioInputStream);
    clip.start();
   }
   catch(Exception ex)
   {
     System.out.println("Error with playing sound.");
     ex.printStackTrace( );
   }
 }

Answer 2

请试试以下内容吗？

public class PlayAudio {
    private AudioInputStream inputStream;
    private AudioFormat format;
    private SourceDataLine sourceDataLine;
    private File file;
    private final int BUFFER_SIZE = 128000;

    public void playSound(String filename) throws Exception {

        String strFilename = filename;
        file = new File(strFilename);

        inputStream = AudioSystem.getAudioInputStream(file);
        format = inputStream.getFormat();

        DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);
        sourceDataLine = (SourceDataLine) AudioSystem.getLine(info);
        sourceDataLine.open(format);
        sourceDataLine.start();

        int nBytesRead = 0;
        byte[] abData = new byte[BUFFER_SIZE];
        while (nBytesRead != -1) {
            try {
                nBytesRead = inputStream.read(abData, 0, abData.length);
            } catch (IOException e) {
                e.printStackTrace();
            }
            if (nBytesRead >= 0) {
                @SuppressWarnings("unused")
                int nBytesWritten = sourceDataLine.write(abData, 0, nBytesRead);
            }
        }

        sourceDataLine.drain();
        sourceDataLine.close();
    }
}
