我们有一个用户提供的字符串,可能包含unicode字符,我们希望机器人输入该字符串。
如何将字符串转换为机器人将使用的keyCodes? 你是如何做到这一点它也是java版本独立(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 = 'á'; // this doesn't, and neither does 'Ă'
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片段,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);
}
这将自动遍历unicode键代码的每个十年,将其映射到相应的VK_NUMPAD等效项并相应地按下/释放键。

KeyEvent Class没有JRE 1.5中许多unicode类的直接映射。如果您在Windows机器上运行它,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.g。找出它们的关键组合,然后将它们映射到某种Object(可能是HashMap?),以便以后查找和执行。
希望这会有所帮助:)

我认为这有点晚了但是......
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“á”

这是否有效,我在笔记本电脑上尝试了同样的功能并不像是帮助我使用java机器人键入unicode字符。为此更多的光。

解决模拟问题时找到的最好方法
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){
}
}
}
