java中的ImageIcon
我正在做一个匹配照片的游戏,我想我可以通过知道contenner标签的名称来重置imageIcon,然后在ismatch方法中ismatch返回false时重置标签图标 在每个标签中写入以下代码,重置仅在第二个标签中起作用。。我该怎么办java中的ImageIcon,java,swing,jlabel,imageicon,Java,Swing,Jlabel,Imageicon,我正在做一个匹配照片的游戏,我想我可以通过知道contenner标签的名称来重置imageIcon,然后在ismatch方法中ismatch返回false时重置标签图标 在每个标签中写入以下代码,重置仅在第二个标签中起作用。。我该怎么办 public ImageIcon firstChoice; public ImageIcon SecoundChoice; public boolean isSelected = false; public boolean isMatc

我建议不要将ImageIcons传递到
ismatch(…)
方法中,而是传递两个包含ImageIcons的JLabel。然后,在该方法中,您可以提取图像图标并进行比较,与之前相同,但更重要的是,您有一个对保存图标的JLabel的引用,然后您可以将它们设置为背景图标或空图标
// "second" is mispelled
public boolean ismatch(JLabel firstChoiceLabel, JLabel secoundChoceLabel) {
ImageIcon firstChoice = firstChoiceLabel.getIcon();
ImageIcon secoundChoice = secoundChoiceLabel.getIcon();
if (firstChoice.getImage() == secoundChoce.getImage()) {
JOptionPane.showMessageDialog(null, " wowo you got it ^^");
isMatch = true;
} else {
JOptionPane.showMessageDialog(null, " notmatced");
isMatch = false;
// here set Icon to null or to background icon.
firstChoiceLabel.setIcon(null);
secoundChoiceLabel.setIcon(null);
}
return isMatch;
}
@MariamAbuEtewy:在引用应用程序资源时使用绝对路径,这确实不是一个好做法。谢谢。。但是如何将Jlabel传递给方法?@MAriam:传递Jlabel的方式与传递ImageIcon的方式相同。
