给SWING程序添加系统托盘图标需要用到两个主要的类:SystemTray和TrayIcon

    SystemTray 通常用于判断系统是否支持托盘图标和添加系统图标功能；

    TrayIcon 用来创建一个图标，然后需要使用SystemTray将add进去；

if (SystemTray.isSupported()) {// 判断系统是否托盘
    TrayIcon icon = new TrayIcon(Toolkit.getDefaultToolkit()
            .createImage("./images/img.png"));// 创建一个托盘图标对象
    PopupMenu menu = new PopupMenu();// 创建弹出菜单
    MenuItem item = new MenuItem("退出");// 创建一个菜单项
    item.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            System.exit(0);
        }
    });
    menu.add(item);// 将菜单项添加到菜单列表
    icon.setPopupMenu(menu);// 将菜单添加到托盘图标
    SystemTray tray = SystemTray.getSystemTray();// 获取系统托盘
    tray.add(icon);// 将托盘图表添加到系统托盘
}

 

    如果需要添加托盘图标闪烁效果，只需调用TrayIcon.setImage(Image image)动态替换托盘图标即可，如下：

Toolkit tk = Toolkit.getDefaultToolkit();
TrayIcon icon = new TrayIcon(tk.createImage("./images/bee.png"));
for(int i=0;i<10;i++){
    icon.setImage(tk.createImage(""));
    Thread.sleep(200);
    icon.setImage(tk.createImage("./images/bee.png"));
    Thread.sleep(200);
}
