     trayIcon.setPopupMenu(popup); 

     try { 
      tray.add(trayIcon); 
     } catch (AWTException e) { 
      System.out.println("TrayIcon could not be added."); 
     } 

    } 
}

什么你实际上缺乏是显示您的PopupMenu的父组件。实现这一目标的方法之一，就是使用一种“看不见”的框架（实际上它是可见的，但与0界和未修饰，所以你不能看到它）是这样的：

import java.awt.AWTException; 
import java.awt.CheckboxMenuItem; 
import java.awt.Frame; 
import java.awt.Menu; 
import java.awt.MenuItem; 
import java.awt.PopupMenu; 
import java.awt.SystemTray; 
import java.awt.Toolkit; 
import java.awt.TrayIcon; 
import java.awt.event.MouseAdapter; 
import java.awt.event.MouseEvent; 
import java.net.MalformedURLException; 
import java.net.URL; 

public class MyTaskTray { 
    public static void main(String arg[]) throws MalformedURLException { 
     final Frame frame = new Frame(""); 
     frame.setUndecorated(true); 
     // Check the SystemTray is supported 
     if (!SystemTray.isSupported()) { 
      System.out.println("SystemTray is not supported"); 
      return; 
     } 
     final TrayIcon trayIcon = new TrayIcon(Toolkit.getDefaultToolkit().getImage(
       new URL("http://home.comcast.net/~supportcd/Icons/Java_Required.jpg")), "Library Drop"); 
     final SystemTray tray = SystemTray.getSystemTray(); 

     // Create a pop-up menu components 
     final PopupMenu popup = createPopupMenu(); 
     trayIcon.setPopupMenu(popup); 
     trayIcon.addMouseListener(new MouseAdapter() { 
      @Override 
      public void mouseClicked(MouseEvent e) { 
       if (e.getButton() == MouseEvent.BUTTON1) { 
        frame.add(popup); 
        popup.show(frame, e.getXOnScreen(), e.getYOnScreen()); 
       } 
      } 
     }); 
     try { 
      frame.setResizable(false); 
      frame.setVisible(true); 
      tray.add(trayIcon); 
     } catch (AWTException e) { 
      System.out.println("TrayIcon could not be added."); 
     } 

    } 

    protected static PopupMenu createPopupMenu() { 
     final PopupMenu popup = new PopupMenu(); 
     MenuItem aboutItem = new MenuItem("About"); 
     CheckboxMenuItem cb1 = new CheckboxMenuItem("Set auto size"); 
     CheckboxMenuItem cb2 = new CheckboxMenuItem("Set tooltip"); 
     Menu displayMenu = new Menu("Display"); 
     MenuItem errorItem = new MenuItem("Error"); 
     MenuItem warningItem = new MenuItem("Warning"); 
     MenuItem infoItem = new MenuItem("Info"); 
     MenuItem noneItem = new MenuItem("None"); 
     MenuItem exitItem = new MenuItem("Exit"); 
     // Add components to pop-up menu 
     popup.add(aboutItem); 
     popup.addSeparator(); 
     popup.add(cb1); 
     popup.add(cb2); 
     popup.addSeparator(); 
     popup.add(displayMenu); 
     displayMenu.add(errorItem); 
     displayMenu.add(warningItem); 
     displayMenu.add(infoItem); 
     displayMenu.add(noneItem); 
     popup.add(exitItem); 
     return popup; 
    } 
} 

从Java 1.7，您可以添加以下行删除从任务栏应用程序栏：

frame.setType(Type.UTILITY); 

Answer 2

我认为你正在寻找一个MouseListener您将添加到您的TrayIcon并点击鼠标按钮时会激活，移动等。为了得到它的左点击操作只是看看MouseEvent（BUTTON1）上的ButtonMasks用于鼠标左键单击。

Answer 3

您可以添加ActionListener到TrayIcon，鼠标DOUBLE_CLICK可以显示JOptionPane

trayIcon.addActionListener(new ActionListener() { 

    @Override 
    public void actionPerformed(ActionEvent e) { 
     JOptionPane.showMessageDialog(null, "This dialog box is run from System Tray"); 
    } 
}); 

Answer 4

你可以在http://docs.oracle.com/javase/tutorial/uiswing/misc/systemtray.html阅读官方教程或退房http://weblogs.java.net/blog/ixmal/archive/2006/05/using_jpopupmen.html的解决方案使用jpopuomenu代替

Answer 5

这应该工作：

trayIcon.addMouseListener(new MouseAdapter() { 
    @Override 
    public void mouseClicked(MouseEvent e) { 
     JOptionPane.showMessageDialog(null, "This shows after a left-click on tray icon"); 
    } 
}); 

覆盖任何其他方法，如果你想要一个不同类型的事件（而不仅仅是点击来自示例的事件 以上）。
