Java 我可以将动画gif文件添加到JButton吗?
我正试图将一个.gif文件添加到JButton中,但似乎无法工作-gif文件没有移动,它显示为一个普通图像 这是我的密码: +ImageButton类:Java 我可以将动画gif文件添加到JButton吗?,java,eclipse,swing,jbutton,animated-gif,Java,Eclipse,Swing,Jbutton,Animated Gif,我正试图将一个.gif文件添加到JButton中,但似乎无法工作-gif文件没有移动,它显示为一个普通图像 这是我的密码: +ImageButton类: import java.awt.Dimension; import java.awt.image.BufferedImage; import java.io.IOException; import javax.imageio.ImageIO; import javax.swing.ImageIcon; import javax.swing.J

+测试类:
导入java.awt.FlowLayout
import javax.swing.JFrame;
public class TestGifButton {
public static void main(String[] args) {
ImageButton button = new ImageButton("level3.gif","level3.gif", 150, 150);
JFrame frame = new JFrame();
frame.setLayout(new FlowLayout());
frame.add(button);
frame.pack();
frame.setVisible(true);
}
}
我使用了一个循环.gif文件
那我该怎么修呢?非常感谢:“(嗯,你可以在你的动画中试试这个
File file = new File("img/ani.gif");
URL url = file.toURI().toURL();
Icon icon = new ImageIcon(url);
JButton aniButt = new JButton(icon);
也许您还必须设置鼠标悬停和按下的图标
但请阅读…(如mKorbel所述!)
或
完整示例:
import java.awt.*;
import java.awt.image.BufferedImage;
import java.net.URL;
import javax.swing.*;
public class ImageSwapOnButton {
public static void main( String[] args ) throws Exception {
URL url = new URL("http://1point1c.org/gif/thum/plnttm.gif");
Image image = Toolkit.getDefaultToolkit().createImage(url);
ImageIcon spinIcon = new ImageIcon(image);
JOptionPane.showMessageDialog(null, new JLabel(spinIcon));
// create a static version of this icon
BufferedImage bi = new BufferedImage(150,150,BufferedImage.TYPE_INT_ARGB);
Graphics g = bi.getGraphics();
g.drawImage(image,0,0,null);
g.dispose();
ImageIcon staticIcon = new ImageIcon(bi);
JButton button = new JButton(staticIcon);
button.setRolloverIcon(spinIcon);
JOptionPane.showMessageDialog(null, button);
}
}
它不能回答我的问题-gif文件可以很容易地显示在JLabel上,但不能显示在我的JButton中。by@MadProgrammerdon不要子类JButton,如果是,则覆盖Api中实现的set(Xxx)图标
