java实现提醒功能
实现提醒功能给你思路吧。
你可以写单独写个线程监视是否有消息传回，然后刷新页面。至于怎么刷新页面其实很简单，写一个事件接口。然后UI页面实现这个接口。有消息传回的时候就刷新页面。
至于系统托盘我给你一个我无聊写的倒计时程序片段，其中有系统托盘。
/**
* 设置系统托盘图标及快捷菜单
*/
private void setIcon(){
addWindowStateListener(new WindowStateListener() {
public void windowStateChanged(WindowEvent e) {
if (getState() == 1) {
setVisible(false);
}
}
});
if (SystemTray.isSupported()) {
tray = SystemTray.getSystemTray();
}
Image image = Toolkit.getDefaultToolkit().getImage(getClass().getResource("china.gif"));
ActionListener defaultListener = new ActionListener() {
public void actionPerformed(ActionEvent e) {
try {
if (e.getActionCommand().equals( "exit")) {
exit();
}
} catch (Exception ex) {
System.out.println("hehehe"+ex.getMessage());
}
}
};
ActionListener openListener = new ActionListener() {
public void actionPerformed(ActionEvent e) {
try {
if (e.getActionCommand().equals("display")) {
setVisible(true);
}
} catch (Exception ex) {
System.out.println("haha"+ex.getMessage());
}
}
};
popup = new PopupMenu();
// 创建[显示]菜单及其事件
MenuItem openItem = new MenuItem("显示");
openItem.addActionListener(openListener);
openItem.setActionCommand("display");
popup.add(openItem);
// 创建[退出]菜单及其事件
MenuItem defaultItem = new MenuItem("退出");
defaultItem.addActionListener(defaultListener);
defaultItem.setActionCommand("exit");
popup.add(defaultItem);
// 右键图标
trayIcon = new TrayIcon(image, "Java倒计时", popup);
trayIcon.setImageAutoSize(true);
trayIcon.addActionListener(defaultListener);
trayIcon.addMouseListener(new MouseAdapter() {
@SuppressWarnings("static-access")
public void mouseClicked(MouseEvent e) {
// 点击系统托盘图标和鼠标左键
if (e.getSource() == trayIcon e.getButton() == e.BUTTON1) {
if (e.getClickCount() == 2)// 双击
{
setVisible(true);
}
}
}
});
try {
tray.add(trayIcon);
} catch (AWTException e1) {
//e1.printStackTrace();
System.out.println("heihei"+e1.getMessage());
}
}
我要用JAVA做一个系统托盘，点最小化按钮，要怎么监听？或者给我来个系统托盘的全代码 不要网上复制的
以下代码直接copy即可运行，注意修改一下托盘图标的文件路径！

java的SystemTray跳出提示的代码？就像xp的网络连接那样，连接成功会弹出一个网络已连接
弹出消息，可以使用 TrayIcon 的 displayMessage() 方法，代码如下：
import java.awt.*;
import java.awt.TrayIcon.MessageType;
import javax.swing.JButton;
import javax.swing.JFrame;
public class App extends JFrame {
private static final long serialVersionUID = 1L;
private TrayIcon trayIcon;
public App() {
this.setSize(300, 200);
this.setLocationRelativeTo(null);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setLayout(new FlowLayout());
JButton btnTest = new JButton("弹出消息");
btnTest.addActionListener(e - {
// 弹出消息
trayIcon.displayMessage("Tray Demo", "Hello World!", MessageType.INFO);
});
this.add(btnTest);
if (SystemTray.isSupported()) {
SystemTray tray = SystemTray.getSystemTray();
Image image = Toolkit.getDefaultToolkit().getImage("images/tray16.png");
this.trayIcon = new TrayIcon(image);
try {
tray.add(trayIcon);
} catch (AWTException e) {
e.printStackTrace();
}
}
}
public static void main(String[] args) {
new App().setVisible(true);
}
}
java高手进个 关于trayIcon问题
jdk1.5以前的版本没有TrayIcon这个类， 直到jdk1.6才有的。
可以升级一下你的jdk。
java开发面试题
结果如下，写的有些复杂了
private static ListTray mergeTrays(ListTray list) {
MapInteger, ListGoods trayMap = new HashMap();
ListTray newTray = new ArrayList();
for (Tray tray : list) {
int id = tray.id;
ListGoods goods = tray.goods;
if (trayMap.containsKey(id)) {
// 将相同托盘id的商品放在一起
ListGoods tempGoods = trayMap.get(id);
for (int i = 0; i goods.size(); i++) {
tempGoods.add(goods.get(i));
}
trayMap.put(id, tempGoods);
}else{
trayMap.put(id, goods);
}
}
for (Map.EntryInteger, ListGoods entry : trayMap.entrySet()) {
int id = entry.getKey();
ListGoods goods = entry.getValue();
MapInteger, Integer goodsMap = new HashMap();
for (int i = 0; i goods.size(); i++) {
Goods good = goods.get(i);
if (goodsMap.containsKey(good.id)) {
goodsMap.put(good.id, goodsMap.get(good.id) + good.count);
}else{
goodsMap.put(good.id, good.count);
}
}
ListGoods newGoods = new ArrayList();
for (Map.EntryInteger, Integer goodEntry : goodsMap.entrySet()) {
Goods good = new Goods();
good.id = goodEntry.getKey();
good.count = goodEntry.getValue();
newGoods.add(good);
}
Tray tray = new Tray();
tray.id = id;
tray.goods = newGoods;
newTray.add(tray);
}
return newTray;
}
