java的frame里面加文字软件_java-反正在JFrame中的图片内添加文本吗？

当然.将文字直接绘制到图片上.在标签中显示图片.

例如.

当然,如果您希望它“更简单”,则还有其他选择.一种是@Reimeus描述的OverlayLayout.这是另一个.它利用了我们可以为标签设置布局并显示其中的组件这一事实.该技术由@mKorbel推广.

import java.awt.*;

import javax.swing.*;

import java.awt.image.BufferedImage;

import java.net.URL;

import javax.imageio.ImageIO;

class TextOnImage {

public static void main(String[] args) throws Exception {

URL url = new URL("http://i.stack.imgur.com/zJ8am.png");

final BufferedImage image = ImageIO.read(url);

Runnable r = new Runnable() {

@Override

public void run() {

JPanel gui = new JPanel(new BorderLayout());

JLabel l = new JLabel(new ImageIcon(image));

l.setLayout(new FlowLayout(FlowLayout.CENTER));

JLabel text = new JLabel("Hi!");

l.add(text);

JOptionPane.showMessageDialog(null, l);

}

};

// Swing GUIs should be created and updated on the EDT

// http://docs.oracle.com/javase/tutorial/uiswing/concurrency/initial.html

SwingUtilities.invokeLater(r);

}

}
