向 Dialog 添加多项选择并使其正常运行

问题描述

我想要的是在 JDialog

 导入 java.awt.*;导入 java.awt.event.*；导入 javax.swing.*；公共类 VocabHelper {私有 JFrame 主框架；私人JPanel主面板；私人JPanel 动物面板；公共 JDialog 动物对话；私有 JLabel 标题Lbl；私人 JLabel 字幕；//调用主界面公共 VocabHelper() {主界面()；}//主要方法公共静态无效主要(字符串[]参数){VocabHelper vocabHelper = new VocabHelper();vocabHelper.showActionEvents();}//编辑主GUI私人无效mainGUI(){mainFrame = new JFrame("VocabHelper");mainFrame.setSize(500, 500);/*titleLbl = new JLabel("词汇助手", JLabel.CENTER);subtitle = new JLabel("选择一个类别继续", JLabel.CENTER);mainFrame.add(titleLbl);mainFrame.add(副标题);*/mainFrame.addWindowListener(new WindowAdapter() {公共无效窗口关闭(窗口事件窗口事件){System.exit(0);}});主面板 = 新的 JPanel();mainFrame.add(mainPanel);mainFrame.setVisible(true);}//创建测验GUI公共无效测验GUI(){quizDialog = 新的 JDialog();quizDialog.setName("测验 1");quizDialog.setSize(500,500);quizDialog.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);quizDialog.setVisible(false);addQuizEvent();}//添加按钮和监听器公共无效showActionEvents(){JButton quizButton = new JButton("quiz");JButton 生物学按钮 = new JButton("生物学");JButton geologyButton = new JButton("地质");JButton historyButton = new JButton("History");JButton sportsButton = new JButton("Sports");JButton techButton = new JButton("技术");quizButton.setActionCommand("测验");bioButton.setActionCommand("生物学");geologyButton.setActionCommand("地质");historyButton.setActionCommand("历史");sportsButton.setActionCommand("运动");techButton.setActionCommand("技术");QuizButton.addActionListener(new ButtonClickListener());bioButton.addActionListener(new ButtonClickListener());geologyButton.addActionListener(new ButtonClickListener());historyButton.addActionListener(new ButtonClickListener());sportsButton.addActionListener(new ButtonClickListener());techButton.addActionListener(new ButtonClickListener());mainPanel.add(QuizButton);mainPanel.add(biologyButton);mainPanel.add(geologyButton);mainPanel.add(historyButton);mainPanel.add(sportsButton);mainPanel.add(techButton);mainFrame.setVisible(true);}//将事件添加到测验对话框这是我想在下面创建多项选择题的地方.公共无效 addQuizEvent() {JButton nextButton = new JButton("Next");nextButton.setActionCommand("下一步");nextButton.addActionListener(new ButtonClickListener());quizDialog.add(nextButton);quizDialog.setVisible(true);}//当按下按钮测验时打开对话框私有类 ButtonClickListener 实现 ActionListener {公共无效actionPerformed(ActionEvent e){字符串命令 = e.getActionCommand();如果(command.equals(测验")){测验GUI();}}}}//多项选择的类测试器我认为这是对话框中的内容，我只是不知道如何.公共类 QuizTester{公共静态无效主要(字符串 [] 参数){//多选题ChoiceQuestion second = new ChoiceQuestion();second.setText("Java的发明者出生在哪个国家?");second.addChoice("澳大利亚", false);second.addChoice("加拿大", true);second.addChoice("丹麦", false);second.addChoice("美国", false);//创建测验并将问题添加到测验然后呈现测验测验 q = new Quiz();q.addQuestion(第二个);q.presentQuestions();}}//多选逻辑的新类导入 java.util.ArrayList；/**一个有多个选择的问题.*/公共类选择问题{私有数组列表<字符串>选择；/**构造一个没有选择的选择题.*/公共选择问题(){选择 = 新的 ArrayList<String>();}/**为这个问题添加一个答案选项.@param 选择要添加的选择@param correct 如果这是正确的选择，则为 true，否则为 false*/public void addChoice(字符串选择，布尔值正确){选择.添加(选择)；如果(正确){//将choices.size() 转换为字符串字符串choiceString = "" +choices.size();设置答案(选择字符串)；}}公共无效显示(){//显示问题文本超级显示()；//显示答案选项for (int i = 0; i 

这是一种得到你想要的东西的方法，你可以接受这个想法并做一些类似

This is a way to get what you want, you can take this idea and do something like this with a CardLayout and a JFrame. You're asking for JDialogs so I made an example with them:

import java.awt.*;
import javax.swing.*;
public class DialogExamples {
    String[] answers = new String[] {"A1", "A2", "A3", "A4"};
    String[] questions = new String[] {"Q1", "Q2", "Q3", "Your score: "};
    int response = -2; //-2 because I'm not sure what value does response has, -1 or 3 on the last option
    int i = 0;
    int score = 0;
    String message = "";
    public DialogExamples() {
        do {
            message = i < 3 ? questions[i] : questions[i] + score;
            while (response != 0) { //Correct answer is A1
                response = JOptionPane.showOptionDialog(null, message, "Title",
                    JOptionPane.DEFAULT_OPTION, JOptionPane.PLAIN_MESSAGE,
                    null, answers, answers[0]);
            }
            i++;
            score++; //Add your logic
            response = -2;
        } while (i < questions.length); //i = number of questions
    }

    public static void main (String args[]) {
        DialogExamples de = new DialogExamples();
    }
}
