本文介绍了ImageIcon无法与我一起使用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我编写了非常简单的代码来显示葡萄的图标，但是代码仍然没有显示任何内容

i wrote very simple code to display an icon of the grapes but still the code doesn't show me anything

这是我的代码

import javax.swing.*; import java.awt.*; public class Code { ImageIcon ii = new ImageIcon("image/grapes2.jpg"); JLabel label = new JLabel("Grapes", ii, SwingConstants.CENTER); JFrame frame = new JFrame("ImageIcon"); public void ui(){ label.setHorizontalTextPosition(SwingConstants.CENTER); label.setVerticalTextPosition(SwingConstants.BOTTOM); label.setIconTextGap(5); label.setOpaque(true); label.setBackground(Color.GRAY); frame.setSize(2300,2300); frame.setVisible(true); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.add(label); }

}

推荐答案

如果即使在最终致电frame.setVisible(true)之后仍然看不到图像图标，那么请查看我在同一上下文中被问到的其他帖子.

If image icon is not visible even after calling frame.setVisible(true) in the end then have a look at my another posts that is asked in the same context.

• 如何从项目文件夹中检索图像?

  从另一个目录读取图像

  尝试

  // Read from src/image folder ii = new ImageIcon(ImageIO.read(getClass().getResource("/image/grapes2.jpg"))); label.setIcon(ii);

  值得阅读如何使用图标以及此处是直接从那里得到的样品.

  It's worth reading How to Use Icons and here is the sample directly from there.

  ImageIcon icon = createImageIcon("images/middle.gif", "a pretty but meaningless splat"); label1 = new JLabel("Image and Text", icon, JLabel.CENTER); ... label3 = new JLabel(icon); /** Returns an ImageIcon, or null if the path was invalid. */ protected ImageIcon createImageIcon(String path, String description) { java.URL imgURL = getClass().getResource(path); if (imgURL != null) { return new ImageIcon(imgURL, description); } else { System.err.println("Couldn't find file: " + path); return null; } }

  了解更多信息使用getResource加载图像，其中视觉上解释它.

  例如名为omega的目录中的类文件. omega/images目录中的图片.

  For e.g. Class file in directory named omega. Image in omega/images directory.
