白雨青工作站发文地址：Java运用jna、vlcj实现音乐和视频的播放器1-主界面设计-白雨青工作站
一、播放器主框架
public class MainFrame {
public JFrame frame;
public int width = 100;
public int height = 350;
public MainFrame(){
frame = new JFrame();
frame.setResizable(false);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(height,width);
frame.setLocationRelativeTo(null);
frame.setLayout(null);
// 去掉窗口的装饰
frame.setUndecorated(true);
//采用指定的窗口装饰风格
frame.getRootPane().setWindowDecorationStyle(JRootPane.NONE);
//设置窗体圆角，最后两个参数分别为圆角的宽度、高度数值，一般这两个数值都是一样的
AWTUtilities.setWindowShape(frame,
new RoundRectangle2D.Double(0.0D, 0.0D, frame.getWidth(), frame.getHeight(), 20.0D, 20.0D));
//设置背景颜色，记住一定要修改frame.getContentPane()的颜色，因为我们看到的都是这个的颜色而并不是frame的颜色
frame.getContentPane().setBackground(Color.LIGHT_GRAY);
frame.setVisible(true);
}
}效果：
二、绘制自定义窗口，添加最小化和关闭按钮
1、自定义一个button类继承JButton
import javax.swing.JButton;
public class DIYButton extends JButton{
public DIYButton() {
super();
// TODO Auto-generated constructor stub
// 不绘制边框
setBorderPainted(false);
//按钮设置为透明，这样就不会挡着后面的背景
setContentAreaFilled(false);
}
}2、自定义一个panel，里面存放logo，窗口名称，最小化，关闭按钮
import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
public class MainFrameBar extends JPanel implements ActionListener{
private JLabel titleLabel;
private DIYButton win_btn_logo;
private DIYButton win_btn_min;
private DIYButton win_btn_close;
public MainFrameBar(){
win_btn_logo = new DIYButton();
win_btn_logo.setBounds(10,5,16,16);
win_btn_logo.setIcon(new ImageIcon("icon/win_btn_logo.png"));
titleLabel = new JLabel();
titleLabel.setBounds(28,3,80,20);
win_btn_min = new DIYButton();
win_btn_min.setBounds(300,5,16,16);
win_btn_min.setIcon(new ImageIcon("icon/win_btn_min.png"));
win_btn_close = new DIYButton();
win_btn_close.setBounds(320,5,16,16);
win_btn_close.setIcon(new ImageIcon("icon/win_btn_close.png"));
setBackground(Color.gray);
setLayout(null);
add(titleLabel);
add(win_btn_logo);
add(win_btn_min);
add(win_btn_close);
win_btn_min.setActionCommand("min");
win_btn_close.setActionCommand("close");
win_btn_min.addActionListener(this);
win_btn_close.addActionListener(this);
}
public void actionPerformed(ActionEvent e) {
if(e.getActionCommand() == "min")
{
MainFrame.getFrame().setExtendedState(JFrame.ICONIFIED);
}
if(e.getActionCommand() == "close")
{
System.exit(0);
}
}
public JLabel getTitleLabel() {
return titleLabel;
}
public void setTitleLabel(JLabel titleLabel) {
this.titleLabel = titleLabel;
}
public DIYButton getWin_btn_logo() {
return win_btn_logo;
}
public void setWin_btn_logo(DIYButton winBtnLogo) {
win_btn_logo = winBtnLogo;
}
public DIYButton getWin_btn_min() {
return win_btn_min;
}
public void setWin_btn_min(DIYButton winBtnMin) {
win_btn_min = winBtnMin;
}
public DIYButton getWin_btn_close() {
return win_btn_close;
}
public void setWin_btn_close(DIYButton winBtnClose) {
win_btn_close = winBtnClose;
}
}效果：
三、绘制中间区域
1、自定义播放器进度条
import java.awt.Color;
import java.awt.Font;
import javax.swing.JLabel;
import javax.swing.JPanel;
/*
* 播放器进度条
* */
public class Rate extends JPanel {
private JLabel rate;
public Rate() {
super();
// TODO Auto-generated constructor stub
setLayout(null);
setBackground(new Color(255,255,255));
rate = new JLabel("", JLabel.CENTER);
rate.setForeground(new Color(255,255,255));
rate.setVisible(true);
rate.setFont(new Font(Font.DIALOG, 0, 25));
add(rate);
setVisible(true);
}
}2、进度条风格
import javax.swing.*;
import javax.swing.plaf.basic.BasicSliderUI;
import java.awt.*;
public class SliderStyle extends BasicSliderUI {
public SliderStyle(JSlider jSlider) {
super(jSlider);
}
// 重绘游标
public void paintThumb(Graphics g) {
Graphics2D g2d = (Graphics2D) g;
BasicStroke stroke = new BasicStroke(3, BasicStroke.CAP_ROUND, BasicStroke.JOIN_ROUND);
g2d.setStroke(stroke);
g2d.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, 1));
g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
GradientPaint gp = new GradientPaint(0, 0, new Color(255,255,255), 0, thumbRect.height, new Color(255,255,255));
g2d.setPaint(gp);
g2d.fillOval(thumbRect.x, thumbRect.y + 5, 10, 10);
BasicStroke stroke1 = new BasicStroke(3, BasicStroke.CAP_ROUND, BasicStroke.JOIN_ROUND);
g2d.setStroke(stroke1);
g2d.drawLine(0, thumbRect.height / 2, thumbRect.x + 8, thumbRect.height / 2);
}
// 重绘进度条
public void paintTrack(Graphics g) {
Graphics2D g2d = (Graphics2D) g;
g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_OFF);// 设定渐变
g2d.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, 0.3f));
g2d.setPaint(new GradientPaint(0, 0, new Color(200, 200, 200), 0, trackRect.height, new Color(255, 255, 255), true));
g2d.setStroke(new BasicStroke(3, BasicStroke.CAP_ROUND, BasicStroke.JOIN_ROUND));
g2d.drawLine(8, trackRect.height / 2 + 1, trackRect.width + 8, trackRect.height / 2 + 1);
}
}3、自定义一个panel，存放上一首、下一首、播放暂停按钮、当前时间、总时间、进度条、歌曲名称

import com.byq.player.ui.style.SliderStyle;
public class MainFrameContain extends JPanel implements ActionListener{
private DIYButton win_btn_prev;
private DIYButton win_btn_play;
private DIYButton win_btn_next;
private Rate rate; // 进度条
private JLabel mediaName;
private JLabel currentTime;
private JLabel totalTime;
private JSlider playProcessSlider;
private int len = 10;
public MainFrameContain(){
win_btn_prev = new DIYButton();
win_btn_prev.setBounds(len,3,40,40);
win_btn_prev.setIcon(new ImageIcon("icon/win_btn_prev.png"));
win_btn_prev.setActionCommand("prev");
add(win_btn_prev);
win_btn_play = new DIYButton();
win_btn_play.setBounds(len+50,3,40,40);
win_btn_play.setIcon(new ImageIcon("icon/win_btn_play.png"));
win_btn_play.setActionCommand("play");
add(win_btn_play);
win_btn_next = new DIYButton();
win_btn_next.setBounds(len+100,3,40,40);
win_btn_next.setIcon(new ImageIcon("icon/win_btn_next.png"));
win_btn_next.setActionCommand("next");
add(win_btn_next);
//歌名
mediaName = new JLabel();
mediaName.setBounds(len+165,-5, 300, 30);
// mediaName.setForeground(new Color(255,255,255));
add(mediaName);
rate = new Rate();
rate.setBounds(len+200,30,100,3);
add(rate);
setBackground(Color.gray);
setLayout(null);
// 当前时间
currentTime = new JLabel("00:00");

totalTime.setBounds(len+305,15, 50, 30);
totalTime.setForeground(new Color(255,255,255));
add(totalTime);
playProcessSlider = new JSlider(0,100,0);
playProcessSlider.setBounds(len+200,20,100,24);
playProcessSlider.setUI(new SliderStyle(playProcessSlider));
playProcessSlider.setBackground(new Color(125,125,125));
playProcessSlider.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
add(playProcessSlider);
win_btn_prev.addActionListener(this);
win_btn_play.addActionListener(this);
win_btn_next.addActionListener(this);
}
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
if(e.getActionCommand() == "prev")
{
System.out.println("prev");
}
if(e.getActionCommand() == "play")
{
System.out.println("play");
win_btn_play.setIcon(new ImageIcon("icon/win_btn_pause.png"));
win_btn_play.setActionCommand("pause");
}
if(e.getActionCommand() == "next")
{
System.out.println("next");
}
if(e.getActionCommand() == "pause")
{
System.out.println("pause");
win_btn_play.setIcon(new ImageIcon("icon/win_btn_play.png"));
win_btn_play.setActionCommand("play");
}
}
}效果：
四、绘制下面区域，菜单列表按钮，声音控制条
1、自定义音量控制条
import java.awt.Color;
import java.awt.Font;
import javax.swing.JLabel;
import javax.swing.JPanel;
/*
* 声音进度条
* */
public class Volume extends JPanel {
private JLabel volume;
public Volume() {
