Java将字符串转换为KeyEvent

我想将String转换为KeyEvent以执行以下操作:

writeKeyboard(myBot,"abcd");

public void writeKeyboard(Robot bot, String st){

char[] arr = arr.toCharArray();

int i = arr.length();

int j = 0;

int keycode;

while (j<i) {

keycode = arr[j].something;

bot.keyPress(keycode);

bot.keyRelease(keycode);

j++;

}

}

回答:

我基本上是在用荣耀的switch声明。简单快捷:

import static java.awt.event.KeyEvent.*;

public class Keyboard {

private Robot robot;

public static void main(String... args) throws Exception {

Keyboard keyboard = new Keyboard();

keyboard.type("Hello there, how are you?");

}

public Keyboard() throws AWTException {

this.robot = new Robot();

}

public Keyboard(Robot robot) {

this.robot = robot;

}

public void type(CharSequence characters) {

int length = characters.length();

for (int i = 0; i < length; i++) {

char character = characters.charAt(i);

type(character);

}

}

public void type(char character) {

switch (character) {

case 'a': doType(VK_A); break;

default:

throw new IllegalArgumentException("Cannot type character " + character);

}

}

private void doType(int... keyCodes) {

doType(keyCodes, 0, keyCodes.length);

}

private void doType(int[] keyCodes, int offset, int length) {

if (length == 0) {

return;

}

robot.keyPress(keyCodes[offset]);

doType(keyCodes, offset + 1, length - 1);

robot.keyRelease(keyCodes[offset]);

}

}

如果要进行一些自定义键键入,则可以扩展该类并重写该type(char)方法。例如:

import static java.awt.event.KeyEvent.*;

public class WindowUnicodeKeyboard extends Keyboard {

private Robot robot;

public WindowUnicodeKeyboard(Robot robot) {

super(robot);

this.robot = robot;

}

@Override

public void type(char character) {

try {

super.type(character);

} catch (IllegalArgumentException e) {

String unicodeDigits = String.valueOf(Character.getCodePoint(character));

robot.keyPress(VK_ALT);

for (int i = 0; i < unicodeDigits.length(); i++) {

typeNumPad(Integer.parseInt(unicodeDigits.substring(i, i + 1)));

}

robot.keyRelease(VK_ALT);

}

}

private void typeNumPad(int digit) {

switch (digit) {

case 0: doType(VK_NUMPAD0); break;

case 1: doType(VK_NUMPAD1); break;

case 2: doType(VK_NUMPAD2); break;

case 3: doType(VK_NUMPAD3); break;

case 4: doType(VK_NUMPAD4); break;

case 5: doType(VK_NUMPAD5); break;

case 6: doType(VK_NUMPAD6); break;

case 7: doType(VK_NUMPAD7); break;

case 8: doType(VK_NUMPAD8); break;

case 9: doType(VK_NUMPAD9); break;

}

}

}

当然,还有改进的余地,但是你知道了。
