Java swing仿酷狗音乐播放器

今天给大家介绍下用java swing开发一款音乐播放器，高仿酷狗音乐播放器，完整源码地址在最下方，本文只列出部分源码，因为源码很多，全部贴不下，下面还是老规矩。来看看运行结果： 

下面我们来看看代码： 

首先看一下主窗口的实现代码： 

package com.baiting;

import java.awt.dimension;
import java.awt.toolkit;

import com.baiting.menu.closewindow;

/**
 * 窗口
 * @author lmq
 *
 */
public abstract class musicwindow extends music {
 
 protected musicframe musicframe;
 
 private string title;
 private int locationx;
 private int locationy;
 
 public musicwindow() {
 title = getconfigmap().get("title").tostring();
 defaultlocation();
 }
 
 public musicwindow(string title,int width,int height) {
 this.title = title;
 setwidth(width);
 setheight(height);
 defaultlocation();
 }
 
 public musicwindow(string title,int width,int height,int locationx,int locationy) {
 this.title = title;
 setwidth(width);
 setheight(height);
 this.locationx = locationx;
 this.locationy = locationy;
 }
 
 private void defaultlocation() {
 dimension screensize = toolkit.getdefaulttoolkit().getscreensize();
 locationx = (screensize.width-getwidth())/2;
 locationy = (screensize.height-getheight())/2;
 }
 
 protected musicframe createwindow() {
 musicframe = new musicframe();
 musicframe.settitle(title);
 musicframe.setsize(getwidth(), getheight());
 //musicframe.setlocation(locationx, locationy);
 musicframe.setlocationrelativeto(null);
 musicframe.addwindowlistener(new closewindow());
 musicframe.setminimumsize(new dimension(600, 450));
 musicframe.setvisible(true);
 return musicframe;
 }

 public string gettitle() {
 return title;
 }

 public void settitle(string title) {
 this.title = title;
 }

 public int getlocationx() {
 return locationx;
 }

 public void setlocationx(int locationx) {
 this.locationx = locationx;
 }

 public int getlocationy() {
 return locationy;
 }

 public void setlocationy(int locationy) {
 this.locationy = locationy;
 }
 
 

 
}

 看看在线下载歌曲的代码：
