基于Java实现动态切换ubuntu壁纸功能
1.在一个文件夹放好图片
2.读取文件夹的图片路径,放入数组
3.调用命令将图片逐个设置为壁纸
使用 Java 在 Ubuntu linux 系统中实现自动切换壁纸的示例程序。这个程序使用了gnome-desktop-item-edit命令来设置壁纸,并通过定时任务来定期切换壁纸
import javax.swing.*; import java.awt.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.util.Timer; import java.util.TimerTask; public class WallpaperChangerGUI extends JFrame { private Timer timer; private String[] imagePaths; private int currentImageIndex; private Point initialClick; public WallpaperChangerGUI() { setTitle("Wallpaper Changer"); // 去掉标题栏 setUndecorated(true); // 设置窗口半透明 setOpacity(0.3f); setSize(300, 150); setDefaultCloseoperation(JFrame.EXIT_ON_CLOSE); setLocationRelativeTo(null); setLayout(new FlowLayout()); JButton startButton = new JButton("Start"); JButton stopButton = new JButton("Stop"); startButton.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { startChangingWallpaper(); } }); stopButton.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { stopChangingWallpaper(); } }); add(startButton); add(stopButton); JButton exitButton = new JButton("Exit"); exitButton.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { System.exit(0); } }); add(exitButton); // 添加鼠标拖动功能 addMouseListener(new MouseAdapter() { @Override public void mousePressed(Mwww.devze.comouseEvent e) { initialClick = e.getPoint(); //System.out.println("press"); } }); addMouseMotionListener(new MouseAdapter() { @Override public void mouseDragged(MouseEvent e) { if (initialClick!= null) { Point currentPos = e.getLocationOnScreen(); setLocation(currentPos.x - initialClick.x, currentPos.y - initialClick.y); } } }); // php假设你的图片路径数组 imagePaths = new String[]{"/home/xxx/图片/壁纸/No.2358/0009.jpg", "/home/xxx/图片/壁纸/No.2358/0010.jpg", "/home/xxx/图片/壁纸/No.2358/0022.jpg" }; currentImageIndex = 0; } public void startChangingWallpaper() { if (timer == null) { timer = new Timer(); timer.scheduleAtFixedRate(new TimerTask() { @Override public void run() { setWallpaper(imagePaths[currentImageIndex]); currentImageIndex = (currentImageIndex + 1) % imagePaths.length; } }, 0, 5*1000); // 每一分钟切换一次壁纸,可以根据需要调整时间间隔 } } public void stopChangingWallpaper() { if (timer!= null) { timer.cancel(); timer = null; } } public static void setWallpaper(String imagePath) { try { // 使用 gnome-desktop-item-edit 命令设置壁纸 Process process = Runtime.getRuntime().exec(new String[]{ "gsettings", "set", "org.gnome.desktop.background", "picture-uri", "file://" + imagePath }); process.waitFor(); if (process.exitValue() == 0) { System.out.println("Wallpaper set successfully to " + imagePath); } else { System.out.println("Failed to set wallpaper."); } } catch (IOException | InterruptedException e) { e.printStackTrace(); } } public static void main(String[] args) { SwingUtilities.inwww.devze.comvokeLater(() -> { WallpaperChangerGU编程I gui = new WallpaperChangerGUI(); gui.setVisible(true); }); } }
