java中的ImageIcon

2019年8月3日 188次阅读

我正在努力匹配照片游戏,我想我可以通过知道参赛者标签的名称来重置imageIcon然后在ismatch在isMatch方法中返回false时重置标签图标.

在每个标签中写下面的代码,重置只在第二个标签上工作..我该怎么办？

public ImageIcon firstChoice;
    public ImageIcon SecoundChoice;
    public boolean isSelected = false;

    public boolean isMatch = true;

    public boolean ismatch(ImageIcon firstChoice, ImageIcon secoundChoce) {

        if (firstChoice.getImage() == secoundChoce.getImage()) {
            JOptionPane.showMessageDialog(null, " wowo you got it ^^");
            isMatch = true;
        } else {
            JOptionPane.showMessageDialog(null, "  notmatced");
            isMatch = false;


        }
        return isMatch;
    }


// label Mouse Clicked

private void label1MouseClicked(java.awt.event.MouseEvent evt) { 

    label1.setIcon(new ImageIcon("G:/Games/icons/File Server Asia.png"));

            if (isSelected == true) {
                ImageIcon icon1 = (ImageIcon) label1.getIcon();
                firstChoice = icon1;
                if (SecoundChoice != null && firstChoice != null) {
                }
                boolean match = ismatch(firstChoice, SecoundChoice);
                if (isMatch == false) {
                    label1.setIcon(null);
                    firstChoice = SecoundChoice = null;

                }

            } else {
                if (SecoundChoice == null) {

                    ImageIcon icon1 = (ImageIcon) label1.getIcon();
                    SecoundChoice = icon1;
                    isSelected = true;

                }


                if (isMatch == false) {
                    label1.setIcon(null);

                }

            }

}

最佳答案 我建议你不要将ImageIcons传递给你的ismatch(…)方法,而是传递两个包含ImageIcons的JLabel.然后在方法内部,您可以提取ImageIcons并比较它们,与之前相同,但更重要的是,您可以引用包含图标的JLabel,然后您可以将它们设置为背景或null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;
}
