What you actually lack is a parent component to show your PopupMenu. One way to achieve this, is to use an "invisible" frame (actually it is visible but with 0-bounds and undecorated, so you can't see it) like this:
您实际上缺少的是显示您的 PopupMenu 的父组件。实现此目的的一种方法是使用“不可见”框架（实际上它是可见的，但具有 0 边界且未装饰，因此您看不到它），如下所示：
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;
}
}
As of Java 1.7, you can add the following line to remove the application bar from the taskbar:
从 Java 1.7 开始，您可以添加以下行以从任务栏中删除应用程序栏：
frame.setType(Type.UTILITY);

you can add ActionListenerto the TrayIcon, mouse double_click can showing JOptionPane
您可以添加ActionListener到TrayIcon，鼠标双击可以显示JOptionPane
trayIcon.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
JOptionPane.showMessageDialog(null, "This dialog box is run from System Tray");
}
});

I think you are looking for a MouseListenerwhich you will add to your TrayIconand will activate when a button on the mouse is clicked,moved etc. To get it to operate for left clicks only have a look at the ButtonMasks on MouseEvent(BUTTON1) being for left mouse clicks.
我认为您正在寻找一个MouseListener您将添加到您的TrayIcon并将在单击、移动鼠标上的按钮时激活的按钮。要让它为左键单击操作，只需查看MouseEvent( BUTTON1)上的 ButtonMasks用于鼠标左键点击。

You could read the official tutorial at http://docs.oracle.com/javase/tutorial/uiswing/misc/systemtray.htmlor check out http://weblogs.java.net/blog/ixmal/archive/2006/05/using_jpopupmen.htmlfor a solution to use a jpopuomenu instead
您可以在http://docs.oracle.com/javase/tutorial/uiswing/misc/systemtray.html阅读官方教程或查看http://weblogs.java.net/blog/ixmal/archive/2006/05 /using_jpopupmen.html用于替代使用 jpopomenu 的解决方案

This should work:
这应该有效：
trayIcon.addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent e) {
JOptionPane.showMessageDialog(null, "This shows after a left-click on tray icon");
}
});
Override any other methods if you want a different kind of event (not just the click event from the example above).
如果您想要不同类型的事件（不仅仅是上面示例中的点击事件），请覆盖任何其他方法。
