问题描述
我们有一个用户提供的可能包含 unicode 字符的字符串,我们希望机器人输入该字符串.
We have a user provided string that may contain unicode characters, and we want the robot to type that string.
如何将字符串转换为机器人将使用的 keyCode?
你是怎么做到的,所以它也是 Java 版本独立的 (1.3 -> 1.6)?
How do you convert a string into keyCodes that the robot will use?
How do you do it so it is also java version independant (1.3 -> 1.6)?
我们为ascii"字符所做的工作是
What we have working for "ascii" chars is
//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);
}
}
推荐答案
基于 javamonkey79 的代码,我创建了以下应该适用于所有 Unicode 值的代码片段...
Based on javamonkey79's code I've created the following snippet which should work for all Unicode values...
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);
}
这会自动遍历 unicode 键码的每个十年,将其映射到相应的 VK_NUMPAD 等效项,并相应地按下/释放键.
This automatically goes through each decade of the unicode key-code, maps it to the corresponding VK_NUMPAD equivalent and presses/releases the keys accordingly.
