Java swing仿酷狗音乐播放器

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：
