java编写 mp3播放器 代码// 你看看吧 。。必须下载 jmf包 如果不知道下载就问我吧
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
import javax.media.bean.playerbean.MediaPlayer; //必须下载 jmf 媒体播放包
public class player extends Applet implements ActionListener {
Button b1, b2;
MediaPlayer player;
public void init() {
player = new MediaPlayer();
setLayout(new FlowLayout());
try{
player.setMediaLocation("file:/F:\\音乐\\mp3\\黑白配.mp3");// file:/不能删除 音频文件路径
} catch (Exception e) {
System.out.println("文件不存在");
}
b1 = new Button("播放");
b2 = new Button("停止");
add(b1);
add(b2);
b1.addActionListener(this);
b2.addActionListener(this);
setSize(200, 200);
setVisible(true);
}
public void actionPerformed(ActionEvent e) {
if (e.getSource() == b1) {
player.start();
} else if (e.getSource() == b2) {
player.stop();
System.out.println(player.getMediaTime().getSeconds());
}
}

怎样通过java打开音乐播放器java中打开音乐播放器音频播放器代码java的方式是使用audioclip类来播放音乐音频播放器代码java，实例如下音频播放器代码java：
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import javax.swing.*;
import java.io.File;
class AudioPlayDemo extends JFrame implements ActionListener {
boolean looping = false;
File file1 = new File("music\\明天会更好.wav");
AudioClip sound1;
AudioClip chosenClip;
JButton playButton = new JButton("播放");
JButton loopButton = new JButton("循环播放");
JButton stopButton = new JButton("停止");
JLabel status = new JLabel("选择播放文件");
JPanel controlPanel = new JPanel();
Container container = getContentPane();
public AudioPlayDemo() {
try {
sound1 = Applet.newAudioClip(file1.toURL());
chosenClip = sound1;
} catch(OutOfMemoryError e){
System.out.println("内存溢出");
e.printStackTrace();
} catch(Exception e){
e.printStackTrace();
}
playButton.addActionListener(this);
loopButton.addActionListener(this);
stopButton.addActionListener(this);
stopButton.setEnabled(false);
controlPanel.add(playButton);
controlPanel.add(loopButton);
controlPanel.add(stopButton);
container.add(controlPanel, BorderLayout.CENTER);
container.add(status, BorderLayout.SOUTH);
setSize(300, 130);
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //关闭窗口时退出程序
}
public void actionPerformed(ActionEvent event) {
if (chosenClip == null) {
status.setText("声音未载入");
return;
}
Object source = event.getSource(); //获取用户洗涤激活音频播放器代码java的按钮
if (source == playButton) {
stopButton.setEnabled(true);
loopButton.setEnabled(true);
chosenClip.play();
status.setText("正在播放");
}
if (source == loopButton) {
looping = true;
chosenClip.loop();
loopButton.setEnabled(false);
stopButton.setEnabled(true);
status.setText("正在循环播放");
}
if (source == stopButton) {
if (looping) {
looping = false;
chosenClip.stop();
loopButton.setEnabled(true);
} else {
chosenClip.stop();
}
stopButton.setEnabled(false);
status.setText("停止播放");
}
}
public static void main(String s[]) {
new AudioPlayDemo();
}
}
只能播放wav格式的歌曲
如何用java做一个音乐播放器？看看其它网友的答案：
首先下载播放mp3的包，比如mp3spi1.9.4.jar 。在工程中添加这个包 。
播放器演示代码如下
package com.test.audio;
import java.io.File;
import java.awt.BorderLayout;
import java.awt.FileDialog;
import java.awt.Frame;
import java.awt.GridLayout;

求用java编写MP3播放器这个需要jmf的相关包,去网上下载下,给你写了个例子
public class TestPlay extends JFrame {
private Component vc, cc;
private JButton file = new JButton("file");
private Player player = null;
public TestPlay() throws HeadlessException, NoPlayerException, MalformedURLException, IOException {
this.add(file);
file.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
JFileChooser f = new JFileChooser();
if(f.showOpenDialog(null)==JFileChooser.CANCEL_OPTION)return;
try {
player = Manager.createPlayer(f.getSelectedFile().toURL());
player.addControllerListener(new ControllerListener() {
public void controllerUpdate(ControllerEvent arg0) {
controllerUpdateImp(arg0);
}
});
player.prefetch();
} catch (Exception e) {
System.out.println(e);
JOptionPane.showMessageDialog(null, e.getMessage());
}
}
});
}
public void controllerUpdateImp(ControllerEvent e) {
if (e instanceof EndOfMediaEvent) {
player.setMediaTime(new Time(0));
player.start();
} else if (e instanceof PrefetchCompleteEvent) {
player.start();
} else if (e instanceof RealizeCompleteEvent) {
vc = player.getVisualComponent();
if (vc != null) this.add(vc, BorderLayout.CENTER);
cc = player.getControlPanelComponent();
if (cc != null) this.add(cc, BorderLayout.SOUTH);
this.pack();
this.setResizable(false);
this.setVisible(true);
} else if (e instanceof ControllerClosedEvent) {
System.exit(0);
}
}
public static void main(String[] args) {
TestPlay t;
try {
t = new TestPlay();
t.setDefaultCloseOperation(t.EXIT_ON_CLOSE);
t.pack();
t.setLocationRelativeTo(null);
t.setVisible(true);
} catch (Exception e) {
JOptionPane.showMessageDialog(null, e.getMessage());
}
