给个代码你参考：import java.awt.*;import java.io.*;import javax.swing.*;import java.awt.event.*;import javax.imageio.ImageIO;public class Test extends JFrame{ private TrayIcon trayIcon;//托盘图标 private SystemTray systemTray;//系统托盘 public Test() { super(系统托盘图标); systemTray = SystemTray.getSystemTray();//获得系统托盘的实例 setSize(150,150); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setVisible(true); try { trayIcon = new TrayIcon(ImageIO.read(new File(0.gif))); systemTray.add(trayIcon);//设置托盘的图标，0.gif与该类文件同一目录 } catch (IOException e1) {e1.printStackTrace();} catch (AWTException e2) {e2.printStackTrace();} this.addWindowListener( new WindowAdapter(){ public void windowIconified(WindowEvent e){ dispose();//窗口最小化时dispose该窗口 } }); trayIcon.addMouseListener( new MouseAdapter(){ public void mouseClicked(MouseEvent e){ if(e.getClickCount() == 2)//双击托盘窗口再现 setExtendedState(Frame.NORMAL); setVisible(true); } }); } public static void main(String args[]) { new Test(); }}
