使用Java实现系统托盘功能的介绍(附源码以及截图)

java中如何,实现系统托盘功能.

系统运行截图

应用核心逻辑说明,隐藏到托盘实质就是讲窗体隐藏.即setvisible(false),显示窗体即就是讲setvisible(true).

项目代码如下:

package org.pdp.frame;

 import java.awt.awtexception;
 import java.awt.menuitem;
 import java.awt.popupmenu;
 import java.awt.systemtray;
 import java.awt.trayicon;
 import java.awt.event.actionevent;
 import java.awt.event.actionlistener;
 import java.net.url;

 import javax.swing.imageicon;
 import javax.swing.jframe;
 import javax.swing.jmenu;
 import javax.swing.jmenubar;
 import javax.swing.jmenuitem;

 
 public class mainframe extends jframe implements actionlistener{

     private static final long serialversionuid = -7078030311369039390l;
     private jmenu menu;
     private jmenubar jmenubar;
     private string [] jmitemname = {"置于托盘","系统退出"};

     public mainframe(){
         super("电话薄");
         init();
         this.setsize(500,400);
         this.setjmenubar(jmenubar);
         this.setlocationrelativeto(null);
         systemtray();    //系统托盘
     }

     /**
      * 初始化界面
      */
     public void init(){
         menu = new jmenu("系统窗体");
         for(int i=0; i<jmitemname.length; i++){
             jmenuitem menuitem = new jmenuitem(jmitemname[i]);
             menuitem.addactionlistener(this);
             menu.add(menuitem);
         }
         this.jmenubar = new jmenubar();
         this.jmenubar.add(menu);
     }

     @override
     public void actionperformed(actionevent e) {
         string actions = e.getactioncommand();
         if("置于托盘".equals(actions)){
             this.setvisible(false);
         }
         if("系统退出".equals(actions)){
             system.exit(0);
         }

     }

     /**系统托盘图标处理.*/
     private void  systemtray(){
         if(systemtray.issupported()){    //判断系统是否支持托盘功能.
             url resource = this.getclass().getresource("systray.jpg");    //获得图片路径
             imageicon icon = new imageicon(resource); //创建图片对象
             popupmenu popupmenu = new popupmenu(); //创建弹出菜单对象
             menuitem itemexit = new menuitem("退出系统");    //创建弹出菜单中的退出项
             menuitem itemshow = new menuitem("显示窗体"); //创建弹出菜单中的显示主窗体项.
             itemexit.addactionlistener(new actionlistener() {     //给退出像添加事件监听
                 @override
                 public void actionperformed(actionevent e) {
                     system.exit(0);
                 }           
             });
             itemshow.addactionlistener(new actionlistener() { //给窗体最小化添加事件监听.
                 @override
                 public void actionperformed(actionevent e) {
                     setvisible(true);
                 }
             });
             popupmenu.add(itemexit);
             popupmenu.add(itemshow);
             trayicon trayicon = new trayicon(icon.getimage(),"电话薄系统",popupmenu);
             systemtray systray = systemtray.getsystemtray();
             try {
                 systray.add(trayicon);
             } catch (awtexception e1) {    }
         }
     }

     /**
      * 主方法
      * @param args
      */
     public static void main(string[] args) {

         new mainframe().setvisible(true);

     }
