播放和停止音乐
我目前正在用菜单中的背景音乐创建一个小型Java游戏，但我无法在停止时按下按钮。 这是我的菜单代码：
import java.applet.Applet;
import java.applet.AudioClip;
import java.awt.BorderLayout;
import java.awt.Button;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Font;

import java.awt.GridBagLayout;
import java.awt.Image;
import java.awt.Label;
import java.awt.Toolkit;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.awt.image.BufferedImage;
import java.io.File;

import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
public class Menu extends JPanel implements ActionListener,MouseListener {
private Image img,troll,troll2;
Audio son = new Audio();
JButton b1,b2,quit;
JOptionPane jop1;
int haut = 50;
int bas = 50;
int bas2 = 600;
int haut2 = 800;
public Menu(String img) {
this(new ImageIcon(img).getImage(),new ImageIcon(img).getImage(),new ImageIcon(img).getImage());
}
public Menu(Image img,Image troll,Image troll2) {
this.setLayout(null);
this.troll = troll;
this.troll2 = troll2;
Font f = new Font("Showcard Gothic", Font.BOLD, 16);
Label la = new Label("Bêta 1.0",Label.CENTER);
la.setForeground(Color.RED);
this.add(la);
la.setBounds(500,800,70,50);
la.setFont(f);
b1 = new JButton("Jouer");
b1.addActionListener(this);
this.add(b1);
b1.setBounds(545, 250, 250, 50);
b1.setForeground(Color.red);
b1.setBackground(Color.yellow);
b2 = new JButton("Option");
b2.addActionListener(this);
this.add(b2);
b2.setBounds(545, 400, 250, 50);
b2.setFont(new java.awt.Font("Serif",1,24));
b2.setBorderPainted(false);
b2.setFocusPainted(false);
quit = new JButton(new ImageIcon("images/quit.png"));
quit.addActionListener(this);
this.add(quit);
quit.setBounds(100,100,50,50);
quit.setBorderPainted(false);
quit.setFocusPainted(false);
this.img = img;
Dimension size = new Dimension(img.getWidth(null), img.getHeight(null));
setPreferredSize(size);
setMinimumSize(size);
setMaximumSize(size);
setSize(size);
}
public void paintComponent(Graphics g) {
g.drawImage(img, 0, 0, null);
g.drawImage(troll2, haut2, bas2, null);
g.drawImage(troll, haut, bas, null);
}
public int getHaut2() {
return haut2;
}
public void setHaut2(int haut2) {
this.haut2 = haut2;
}
public int getBas2() {
return bas2;
}
public void setBas2(int bas2) {
this.bas2 = bas2;
}
public int getHaut() {
return haut;
}
public void setHaut(int haut) {
this.haut = haut;
}
public int getBas() {
return bas;
}
public void setBas(int bas) {
this.bas = bas;
}
@Override
public void mouseClicked(MouseEvent e) {
// TODO Auto-generated method stub
}
@Override
public void mouseEntered(MouseEvent e) {
// TODO Auto-generated method stub
}
@Override
public void mouseExited(MouseEvent e) {
// TODO Auto-generated method stub
}
@Override
public void mousePressed(MouseEvent e) {

}
@Override
public void mouseReleased(MouseEvent e) {

}
@Override
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
if(e.getSource() == quit){
int option = jop1.showConfirmDialog(null,
"êtes-vous sûr de vouloir quitter le jeu ?",
"Quitter TrollGames",
JOptionPane.YES_NO_OPTION,
JOptionPane.QUESTION_MESSAGE);
if(option == JOptionPane.YES_OPTION){
System.exit(0);
}
}
if(e.getSource() == b2){
// How to stop the music ??? //
}
}
}
这是我的音乐代码：
import java.io.*;
import java.util.ArrayList;
import javax.sound.sampled.*;
import javax.swing.ImageIcon;
public class Audio extends Thread
{
String slash = System.getProperty("file.separator");
File songs_directory = new File(System.getProperty("user.dir") + slash + "musiques"); //You have to specify the directory containing your tracks.
ArrayList<File> songs_list = new ArrayList<File>();
public void run()
{
for(File file : songs_directory.listFiles())
if(file.isFile())
songs_list.add(file);
while(true)
Random_selection();
}
public void Random_selection()
{
int track_number = (int)Math.floor(Math.random()*songs_list.size());
File song_to_read = songs_list.get(track_number);
PlaySong(song_to_read);
}
public void PlaySong(File song_to_read)
{
long song_lenght = 0;
try{ Clip clip = AudioSystem.getClip();
clip.open(AudioSystem.getAudioInputStream(song_to_read));
song_lenght = clip.getMicrosecondLength();
clip.start();
}catch (Exception exc) {exc.printStackTrace(System.out);}
long time_init = System.currentTimeMillis();
while(System.currentTimeMillis() < time_init + song_lenght/1000)
try{Thread.sleep(1000);}catch(InterruptedException e){};
}
}
以下是我的JFrame代码：
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
public class Fenetre extends JFrame implements ActionListener{
Audio son = new Audio();
Menu panel = new Menu(new ImageIcon("images/fond.jpg").getImage(),new ImageIcon("images/troll.png").getImage(),new ImageIcon("images/troll2.png").getImage());
int x,y,x2,y2;
public Fenetre(){
this.getContentPane().add(panel);
this.setUndecorated(true);
this.setVisible(true);
this.setLocationRelativeTo(null);
this.setDefaultLookAndFeelDecorated(false);
this.setExtendedState(MAXIMIZED_BOTH);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
son.start();
go();
}
private void go(){
for(int i = x; i<2500;i+=25){
for(int j = y;j<2500;j+=50){
boolean backX = false;
boolean backY = false;
while (true) {
if (x < 1)
backX = false;
if (x > panel.getWidth() - 85)
backX = true;
if (y < 1)
backY = false;
if (y > panel.getHeight() - 85)
backY = true;
if (!backX)
panel.setHaut(++x);
else
panel.setHaut(--x);
if (!backY)
panel.setBas(++y);
else
panel.setBas(--y);
repaint();
try{
Thread.sleep(5);
}catch(InterruptedException e){
e.printStackTrace();
}
}
}
}
}
@Override
public void actionPerformed(ActionEvent arg0) {
// TODO Auto-generated method stub
if(arg0.getSource() == panel.b2){
System.exit(0);
}
}}
