java - 我创建了一个 JButton，单击时会播放声音 - 如何在更多按钮上实现它

Question

package pkgnew;
import javax.swing.JButton;
import javax.swing.JFrame;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.ImageIcon;
import javax.swing.JPanel;
import java.io.File;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;

public class bob
{
JButton test = new JButton("");
JButton test1 = new JButton("");
JButton test2 = new JButton("");
JButton test3 = new JButton("");
JPanel panel = new JPanel();

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( );
   }
 }    

 public bob() {

    JFrame frame = new JFrame("Movie Stars");
    test.setIcon(new ImageIcon("C:\\Users\\bob\\Desktop\\Leonardo.jpg"));
    test1.setIcon(new ImageIcon("C:\\Users\\bob\\Desktop\\Bruce.jpg"));
    test2.setIcon(new ImageIcon("C:\\Users\\bob\\Desktop\\Jim.jpg"));
    test3.setIcon(new ImageIcon("C:\\Users\\bob\\Desktop\\Robert.jpg"));

    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setLocationRelativeTo(null);
    frame.pack();
    frame.add(panel);
    frame.setSize(1000, 800);
    frame.setResizable(true);
    frame.setVisible(true);

    panel.add(test);
    panel.add(test1);
    panel.add(test2);
    panel.add(test3);

    panel = new JPanel(new GridLayout(2,2));

    test.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e)
        {
         playSound("Leonardo.wav");

        }  
    }
  );
}  

public static void main(String[] args) 
{

    bob t = new bob();
} 
}

所以基本上我有一个带有 4 个图片按钮的网格，并且我正在尝试使其当您单击每张图片时都会播放声音。我为其中一个按钮实现了它，但是到目前为止，我为使其适用于其他 3 个按钮所做的一切尝试都没有成功。我以为我只是复制 test.addActionListener(new ActionListener() {) 并将“test”替换为“test1”，但事实并非如此，我还尝试在该播放中添加“else if catch”循环，以便如果 e.getSource() == test 则它会播放其中一种声音，否则如果 e.getSource() == test2 它将播放另一种声音，但是没有工作

正如其他人在评论中所说，您的代码运行得很好。

我下载 Netbeans 只是为了给您检查一下:p

这是按预期工作的代码:

这是我使用的 ActionListener 代码(使用 2 种不同的声音进行测试):

test.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e)
    {
     playSound("C:\\Users\\DT\\Music\\Beep.wav");
     JOptionPane.showMessageDialog(null, "Beep1 Just Went Off");
    }  
});
test1.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e)
    {
     playSound("C:\\Users\\DT\\Music\\Beep2.wav");
     JOptionPane.showMessageDialog(null, "Beep2 Just Went Off");
    }  
});
test2.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e)
    {
     playSound("C:\\Users\\DT\\Music\\Beep.wav");
     JOptionPane.showMessageDialog(null, "Beep3 (Beep.wav) Just Went Off");
    }  
});
test3.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e)
    {
     playSound("C:\\Users\\DT\\Music\\Beep.wav");
     JOptionPane.showMessageDialog(null, "Beep4 (Beep.wav) Just Went Off");
    }  
});
