Java swing仿酷狗音乐播放器

 更新时间：2017年06月05日 11:04:50   作者：明礼馨德  
这篇文章主要为大家详细介绍了Java swing实现音乐播放器，Java开发图形界面程序音乐播放器仿酷狗音乐播放器，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

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：
