Я хочу воспроизводить mp3-файл при нажатии кнопки, поэтому я создал кнопку, которая создает аудиоплеер, для которого, очевидно, требуется источник. Я пытался передать источник по пути или URI, но он не работает, я всегда получаю одну и ту же ошибку (URISyntaxException). Я инициализирую свои кнопки следующим образом:
public class GUI
{
private String localFolder=System.getProperty("user.dir");
// I'm taking the actual folder where my app is executed
private void audioInitialize() {
localFolder+=File.pathSeparator+"src"+File.pathSeparator+"InUse"+File.pathSeparator;
File saves=new File(localFolder); // need the path for other use
AudioButton button0=new AudioButton("SONG", saves.getPath()+File.pathSeparator+"song.mp3", true);
buttons.add(button0);
/*
*
*
*/
}
Это мой класс AudioButton:
public class AudioButton extends JButton implements ActionListener
{
private String uri;
private final boolean isCustom;
public AudioButton(String label, String uri, boolean isCustom) {
this.uri=uri;
this.isCustom=isCustom;
this.setText(label);
this.setBackground(new Color(205, 205, 205));
this.setBorderPainted(true);
this.addActionListener(this);
}
public String getUri() {return this.uri;}
public boolean isCustom() {return this.isCustom;}
@Override
public void actionPerformed(ActionEvent e)
{
AudioPlayer player=new AudioPlayer(this.uri);
player.getPlayer().play();
}
}
Есть AudioPlayer:
public class AudioPlayer extends JPanel
{
private final String uri;
private Media media;
private MediaPlayer mediaPlayer;
public AudioPlayer(String uri) {
@SuppressWarnings("unused")
JFXPanel pane=new JFXPanel();
this.uri=uri;
media=new Media(uri);
mediaPlayer=new MediaPlayer(media);
}
public MediaPlayer getPlayer() {return this.mediaPlayer;
}
И это вывод консоли :
