如何使Java.awt.Robot类型为unicode字符?(可能吗?)

automation unicode java

Greg Domjan · 技术社区 · 16 年前

我们有一个用户提供的字符串,可能包含unicode字符,我们希望机器人键入该字符串。

如何将字符串转换为机器人将使用的键码?
您是如何做到这一点的,这样它也是独立于java版本的(1.3->1.6)?

我们为“ascii”字符工作的是

//char c = nextChar();
//char c = 'a'; // this works, and so does 'A'
char c = 'Ã¡'; // this doesn't, and neither does 'Ä'
Robot robot = new Robot();
KeyStroke key = KeyStroke.getKeyStroke("pressed " + Character.toUpperCase(c) );
if( null != key ) {
  // should only have to worry about case with standard characters
  if (Character.isUpperCase(c))
  {
    robot.keyPress(KeyEvent.VK_SHIFT);
  }

  robot.keyPress(key.getKeyCode());
  robot.keyRelease(key.getKeyCode());

  if (Character.isUpperCase(c))
  {
    robot.keyRelease(KeyEvent.VK_SHIFT);
  }
}

基于javamonkey79的代码,我创建了以下代码段,它应该适用于所有Unicode值。。。

public static void pressUnicode(Robot r, int key_code)
{
    r.keyPress(KeyEvent.VK_ALT);

    for(int i = 3; i >= 0; --i)
    {
        // extracts a single decade of the key-code and adds
        // an offset to get the required VK_NUMPAD key-code
        int numpad_kc = key_code / (int) (Math.pow(10, i)) % 10 + KeyEvent.VK_NUMPAD0;

        r.keyPress(numpad_kc);
        r.keyRelease(numpad_kc);
    }

    r.keyRelease(KeyEvent.VK_ALT);
}

这个 KeyEvent Class JRE 1.5中的许多unicode类没有直接映射。如果您在Windows机箱上运行此操作,您可能需要编写一个自定义处理程序,执行以下操作:

Robot robot = new Robot();
char curChar = 'Ã';

// -- isUnicode( char ) should be pretty easy to figure out
if ( isUnicode( curChar ) ) {
   // -- this is an example, exact key combinations will vary
   robot.keyPress( KeyEvent.VK_ALT );

   robot.keyPress( KeyEvent.VK_NUMBER_SIGN );
   robot.keyRelease( KeyEvent.VK_NUMBER_SIGN );

   // -- have to apply some logic to know what sequence
   robot.keyPress( KeyEvent.VK_0 );
   robot.keyRelease( KeyEvent.VK_0 );
   robot.keyPress( KeyEvent.VK_1 );
   robot.keyRelease( KeyEvent.VK_1 );
   robot.keyPress( KeyEvent.VK_9 );
   robot.keyRelease( KeyEvent.VK_9 );
   robot.keyPress( KeyEvent.VK_5 );
   robot.keyRelease( KeyEvent.VK_5 );

   robot.keyRelease( KeyEvent.VK_ALT );
}

e、找出它们的键组合是什么,然后将它们映射到某种对象(可能是HashMap?),以便以后查找和执行。

我想这有点晚了,但是。。。

Robot robot = new Robot();

   robot.keyPress( KeyEvent.VK_DEAD_ACUTE);

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

   robot.keyRelease( KeyEvent.VK_DEAD_ACUTE );

只需键入一个“”

import java.awt.AWTException;
import java.awt.Robot;

public class MyRobot {

    public static void typeString(String s)
        {
            try {
            Robot robik = new Robot();
            byte[] bytes = s.getBytes();
            for (byte b : bytes)
            {
                int code = b;
                // keycode only handles [A-Z] (which is ASCII decimal [65-90])
                if (code > 96 && code < 123) code = code - 32;
                robik.delay(40);
                robik.keyPress(code);
                robik.keyRelease(code);
            }
        } catch (AWTException e){

    }
  }
