Java运用jna、vlcj实现音乐和视频的播放器1-主界面设计

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);
	}
}

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;
	}
}

 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 java.awt.Color;
import java.awt.Cursor;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class MainFrameContain extends JPanel implements ActionListener{
	
	private DIYButton win_btn_prev;
	private DIYButton win_btn_play;

	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_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");
	    currentTime.setBounds(len+165,15, 50, 30);
	    currentTime.setForeground(new Color(255,255,255));
        add(currentTime);
	    
        // 结束时间
        totalTime = 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"); 
        }
	}
}

 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() {
		super();
		// TODO Auto-generated constructor stub
		setLayout(null);
        setBackground(new Color(255,255,255));
        volume = new JLabel("", JLabel.CENTER);
        volume.setForeground(new Color(255,255,255));
        volume.setVisible(true);
        volume.setFont(new Font(Font.DIALOG, 0, 25));
        add(volume);
        setVisible(true);
	}
}

2、自定义一个panel,存放音量控制条和菜单按钮

import java.awt.Color;
import java.awt.Cursor;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.ImageIcon;
import javax.swing.JPanel;
