无法使 TrayIcon 中的 MenuItem 可点击

Question

我制作了一个简单的 java 程序来显示一个系统托盘，其中包含许多在单击它时出现的菜单项。 所有这些菜单项都是可点击的。

我在 ActionListener 中包含了托盘图标功能的代码。

就我而言，我已经包含了许多选项，但是没有一个 ActionListener 正在工作。

该程序不会引发错误，但我无法为按钮包含更多功能。

这是我的代码：

    
    public static void showTray()
    {
        if (systemTray==null)
        {           
            System.exit(0); 
        }
        else
        {
            System.out.println("SystemTray works"); 
        }
        //String[] args= {"",""};
          
        // ImageIcon icon = new ImageIcon("/home/ioss/Downloads/hexagon-clipart.jpeg");
        systemTray.setImage("/home/ioss/Downloads/c4f9.png"); 
        systemTray.setStatus("Running"); 
        

        // MenuItem user_email=new MenuItem(email);
        MenuItem chgImg=new MenuItem("Change Icon");    
        MenuItem link =new MenuItem ("My Desklog"); 
            MenuItem version=new MenuItem("Version-1.0.4");
           
            systemTray.getMenu().add(link).setShortcut('q');
            systemTray.getMenu().add(version).setShortcut('q');
            
          
           
//          systemTray.getMenu().add(of).setShortcut('q');
//          systemTray.getMenu().add(on).setShortcut('q');
//          systemTray.getMenu().add(logout1).setShortcut('q');
            systemTray.getMenu().add(chgImg).setShortcut('q');
        
        PopupMenu pm=new PopupMenu();   
        
        op=new MenuItem("About"); 
          systemTray.getMenu().add(op).setShortcut('q');
        
        on =new MenuItem("Go Online");
         systemTray.getMenu().add(on).setShortcut('q');
         on.setEnabled(false);
        
ActionListener online = new ActionListener() {

            
            @Override
            public void actionPerformed(ActionEvent arg0) { 
                System.out.println("Inside Online Listener"); 
                systemTray.setImage("/home/ioss/Downloads/c4f9.png"); 
                    
                    System.out.println("On enabled");
                    
                of.setEnabled(true);
                System.out.println("online..");
                systemTray.setStatus("online");                 
            }
            
        };
        
        of =new MenuItem("Go Offline");
        
        
        ActionListener offline = new ActionListener() {

            
            @Override

                systemTray.setImage("/home/ioss/Downloads/prohibition-symbol.jpeg"); 
                on.setEnabled(true);
                of.setEnabled(false);
                System.out.println("offline..");
                systemTray.setStatus("offline"); 
                
            }
            
        };
          systemTray.getMenu().add(of).setShortcut('q');
        
//  PopupMenu pm=new PopupMenu();   
//      of =new MenuItem("Go Offline");
//      op=new MenuItem("About");

尝试在actonListener中添加一个 implements 方法，它不一定需要一个主体。 像这样的东西：

public void actionPerformed(ActionEvent e) {
                // TODO Auto-generated method stub
                
            }
