如何从项目文件夹中检索图像？
我正在尝试创建一个Java桌面应用程序，我有一个JLabel ，我在那里随机播放图像。 我正在从我的电脑的任何驱动器上的文件夹中检索图像。 现在我想从图像文件夹名称可用的项目文件夹中检索所有图像。
F:/>Kiosk | |___src | |___lib | |___koisk | |__main1.java | |__images
这是我的代码我怎样才能实现这一目标？
public class ImageShuffle1 extends JPanel { private List list = new ArrayList(); private List shuffled; private JLabel label = new JLabel(); private int width = 700; private int height = 700; private Timer timer = new Timer(1000, new ActionListener() { @Override public void actionPerformed(ActionEvent e) { update(); } }); public ImageShuffle1() { try { list.add(resizeImage(ImageIO.read(new File("E:\\SOFTWARE\\TrainPIS\\res\\drawable\\c.jpg")))); list.add(resizeImage(ImageIO.read(new File("E:\\SOFTWARE\\TrainPIS\\res\\drawable\\d.jpg")))); list.add(resizeImage(ImageIO.read(new File("E:\\SOFTWARE\\TrainPIS\\res\\drawable\\e.jpg")))); list.add(resizeImage(ImageIO.read(new File("E:\\SOFTWARE\\TrainPIS\\res\\drawable\\f.jpg")))); } catch (IOException e) { e.printStackTrace(); } shuffled = new ArrayList(list); Collections.shuffle(shuffled); timer.start(); } private BufferedImage resizeImage(BufferedImage originalImage) throws IOException { BufferedImage resizedImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB); Graphics2D g = resizedImage.createGraphics(); g.drawImage(originalImage, 0, 0, width, height, null); g.dispose(); return resizedImage; } private void update() { if (shuffled.isEmpty()) { shuffled = new ArrayList(list); Collections.shuffle(shuffled); } BufferedImage icon = shuffled.remove(0); label.setIcon(new ImageIcon(icon)); } private void display() { JFrame f = new JFrame("ImageShuffle"); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.add(this); f.add(label); f.pack(); f.setLocationRelativeTo(null); f.setVisible(true); } public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { @Override public void run() { new ImageShuffle1().display(); } }); } }
提前致谢
将项目中的images文件夹中的所有图像与src文件夹并行放置。
F:/>Kiosk | |___src | |___lib | |___koisk | |__main1.java | |__images | |__c.jpg |__d.jpg |__e.jpg |__f.jpg
使用此代码
list.add(resizeImage(ImageIO.read(new File("images\\c.jpg")))); list.add(resizeImage(ImageIO.read(new File("images\\d.jpg")))); list.add(resizeImage(ImageIO.read(new File("images\\e.jpg")))); list.add(resizeImage(ImageIO.read(new File("images\\f.jpg"))));
– 编辑 –
你可以尝试任何一个
// Read from same package list.add(resizeImage(ImageIO.read(getClass().getResourceAsStream("c.png")))); // Read from absolute path list.add(resizeImage(ImageIO.read(new File("E:\\SOFTWARE\\TrainPIS\\res\\drawable\\c.png")))); // Read from images folder parallel to src in your project list.add(resizeImage(ImageIO.read(new File("images\\c.jpg"))));
对所有四个图像重复任何一个。
