你好所以我做了一个java程序，每次按下一个键时都会显示keyEvent.getKeyCode()。

目的是能够使某种机器人能够使用 java 机器人类和一些 keyEvent 来驱动 git/skyrim/fraps。

但是，它似乎无法映射 AZERTY 键盘，因为您可以看到一些 keyEvent 代码是相同的。

azerty 映射

还有其他驱动键盘的方法吗？

如果您想知道，这是该程序：

主要课程：

package keykeykey;
import java.awt.BorderLayout;

import javax.swing.JFrame;
import javax.swing.JTextField;

public class MainClass {
  public static void main(String args[]) throws Exception {
    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    JTextField nameTextField = new JTextField();
    frame.add(nameTextField, BorderLayout.NORTH);

    JTextField codeTextField = new JTextField();
    frame.add(codeTextField, BorderLayout.SOUTH);

    MyKeyListener myKeyListener = new MyKeyListener(codeTextField, nameTextField);
    nameTextField.addKeyListener(myKeyListener);

    frame.setSize(250, 100);
    frame.setVisible(true);
  }
}

keyListener 重定义

package keykeykey;

import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;

import javax.swing.JTextField;

public class MyKeyListener extends KeyAdapter implements KeyListener {

    public JTextField codeTextField;
    public JTextField writeTextField;

    public MyKeyListener(JTextField codeTextField, JTextField writeTextField) {
        this.codeTextField = codeTextField;
        this.writeTextField = writeTextField;
    }

    @Override
    public void keyPressed(KeyEvent keyEvent) {
    printIt("Pressed", keyEvent);
    codeTextField.setText("code = " + keyEvent.getKeyCode());
  }

  @Override
    public void keyReleased(KeyEvent keyEvent) {
    codeTextField.setText("");
    writeTextField.setText("");
  }

  @Override
    public void keyTyped(KeyEvent keyEvent) {
    //do nothing
  }

  private void printIt(String title, KeyEvent keyEvent) {
    int keyCode = keyEvent.getKeyCode();
    String keyText = KeyEvent.getKeyText(keyCode);
    System.out.println(title + " : " + keyText + " / " + keyEvent.getKeyChar() + " code = " + keyEvent.getKeyCode());
  }

}

谢谢。

Ps：是的，我知道 autoHotKey，但是我需要一种强类型语言，而且我喜欢 java。

编辑

我一定没有正确表达自己，我知道 shift+VK1 使“1”，其他键也是如此。

我的问题是，正如您在第一张图片中看到的那样，某些键会生成无法识别的键事件（带有红色条的事件）。

例如这两个键：

可以根据应用的修饰符更改虚拟键。实际结果取决于键盘驱动程序本身，但例如...

Shift+1将生成KeyEventwho keyCodeis KeyEvent.VK_1，但 who keyCharis!

您基本上忽略了这些修饰符...
