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， * 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：
