java - 将 doClick 放入 JOptionPane 中

Question

我是java初学者，在制作doClick按钮时遇到一些麻烦。我不明白它是如何工作的，我的代码中需要它。

     JButton easyb  = new JButton("Easy");
     JButton mediumb = new JButton("Medium");
     JButton hardb = new JButton("Hard");

    String fn = JOptionPane.showInputDialog("Choose your level \n", easyb.doClick() ,mediumb.doClick(), hardb.doClick() , "\n \n Easy are words you know everyday \n Medium are words that you have seen before \n Hard are words that you have rarely seen in your life"); 

我希望输出如下所示:

    Choose your level
    easy   medium   hard ( you can click on the words)

    Easy are words you have said everyday
    Medium are words that you have seen before
    Hard are words that you have rarely seen in your life

Answer 1

您可以使用更好的 JOptionPane，即 JOptionPane.showOptionDialog:

  String[] options = { "Easy", "Medium", "Hard" };
  int selection = JOptionPane.showOptionDialog(null, "Choose Something", "Title",
        JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE, null,
        options, options[0]);


  // ***** oops! this should be >= 0, not > 0. Corrected!
  if (selection >= 0) {
     System.out.println("Selected: " + options[selection]);
  }

根据您的评论:

The button part works but I have two problems. The first is that I don't think it will show how I want the output to be like I said in my question. The words need to be there as well.

您需要做的就是放入 if/else block 或更好的 switch 语句，该语句根据选择的选项(0、1 或 2)输出正确的字符串。

例如，

if (selection >= 0) {
   String word = options[selection];
   case selection 0: 
      // output stuff based on easy
      break;
   case selection 1:
      // output stuff based on medium selection,....
      break;
   //.... etc.../
}

The second problem will show the whole code and then you can see the problem.

我看到了您的整个代码，但没有看到与之相关的具体问题。

Ordous 建议您使用 3 个按钮创建一个 JPanel，为它们提供 ActionListener，然后将该 JPanel 放入 JOptionPane 或 JDialog 中，然后显示它。
