我使用了以下循环,但它只输入第一个字符,其余为数字,任何想法?

import java.awt.*;

import javax.swing.KeyStroke;

public class test {

    public static void main(String[] args) throws AWTException
    {
        Robot r = new Robot();

        String s = "Face";

        for (int i = 0; i < s.length(); i++) 
        {
            char res = s.charAt(i);
            r.keyPress(res);
            r.keyRelease(res);  
            r.delay(1000);
        }           
    }
}

输出输入:F135

keyPress / Release方法需要一个int值,表示要键入的字符。这些值是由KeyEvent.VK _ ???确定的每个字符的关键代码。变量

尝试:

import java.awt.*;
import java.util.*;
import java.lang.reflect.Field;
import java.awt.event.*;
import javax.swing.*;

public class RobotCharacter
{
    public static void main(String[] args)
        throws Exception
    {
        JTextField textField = new JTextField(10);

        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
        frame.add( textField );
        frame.pack();
        frame.setLocationRelativeTo( null );
        frame.setVisible( true );

        Robot robot = new Robot();
        typeCharacter(robot, "a");
        typeCharacter(robot, "b");
        typeCharacter(robot, "C");
        typeCharacter(robot, "D");
     }

    public static void typeCharacter(Robot robot, String letter)
    {
        try
        {
            boolean upperCase = Character.isUpperCase( letter.charAt(0) );
            String variableName = "VK_" + letter.toUpperCase();

            Class clazz = KeyEvent.class;
            Field field = clazz.getField( variableName );
            int keyCode = field.getInt(null);

            robot.delay(1000);

            if (upperCase) robot.keyPress( KeyEvent.VK_SHIFT );

            robot.keyPress( keyCode );
            robot.keyRelease( keyCode );

            if (upperCase) robot.keyRelease( KeyEvent.VK_SHIFT );
        }
        catch(Exception e)
        {
            System.out.println(e);
        }
    }
}

然而,即使这对所有角色都不起作用。例如,在我的键盘上,&#34;%&#34;高于&#34; 5&#34;。您无法使用VK_PERCENT。所需的关键行程是VK_5以及换档。无法知道键盘的实际映射以自动执行此操作。

所以机器人不是一个很好的方法。

Robot类使用此处定义的键代码:http://docs.oracle.com/javase/1.5.0/docs/api/java/awt/event/KeyEvent.html,而不是原始字符。你需要这样称呼它:

r.keyPress(KeyEvent.VK_A);
r.keyRelease(KeyEvent.VK_A);

@ camickr我对你的scipt做了一个小编辑,以容纳一个字符串而不是一个字母。如下请见 。它帮助我谢谢:)函数调用:typeCharacter(robot, "thanks");

public static void typeCharacter(Robot robot, String letter)
      {

     for(int i=0;i<letter.length();i++){
      try
      {
          boolean upperCase = Character.isUpperCase( letter.charAt(i) );
          String KeyVal=Character.toString(letter.charAt(i));
          String variableName = "VK_" + KeyVal.toUpperCase();
          Class clazz = KeyEvent.class;
          Field field = clazz.getField( variableName );
          int keyCode = field.getInt(null);

          robot.delay(1000);

          if (upperCase) robot.keyPress( KeyEvent.VK_SHIFT );

          robot.keyPress( keyCode );
          robot.keyRelease( keyCode );

          if (upperCase) robot.keyRelease( KeyEvent.VK_SHIFT );
      }
      catch(Exception e)
      {
          System.out.println(e);
      }
      }

  }

您还可以将String加载到剪贴板,然后将其粘贴到您想要的位置。

                StringSelection selection = new StringSelection("Hello World");
                Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
                clipboard.setContents(selection, selection);

                robo.keyPress(KeyEvent.VK_CONTROL);
                robo.keyPress(KeyEvent.VK_V);
                robo.keyRelease(KeyEvent.VK_V);
                robo.keyRelease(KeyEvent.VK_CONTROL);

如果您创建一个接收要键入的字符串的函数,则可以让您的生活变得轻松:

public void keyboardString(final String text) {
    if (text != null) {
        try {
            final Robot robot = new Robot();
            for (int i = 0; i < text.length(); i++) {
                final char ch = text.charAt(i);
                final boolean upperCase = Character.isUpperCase(ch);
                final int keyCode = KeyEvent.getExtendedKeyCodeForChar(ch);
                robot.delay(10);
                if (upperCase) {
                    robot.keyPress(KeyEvent.VK_SHIFT);
                }
                robot.keyPress(keyCode);
                robot.keyRelease(keyCode);
                if (upperCase) {
                    robot.keyRelease(KeyEvent.VK_SHIFT);
                }
            }

        } catch (final Exception e) {
            System.out.println(e);
        }
    }
}
