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++;
}
}
我基本上是在使用美化的switch声明。简单快速：
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);
}
}

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]);
}
}
如果您想要一些自定义键输入，您可以扩展该类并覆盖该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，但你明白了。
我使用剪贴板来解决问题...
public static void type(String characters) {
Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
StringSelection stringSelection = new StringSelection( characters );
clipboard.setContents(stringSelection, clipboardOwner);
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_CONTROL);
}
您可以通过 Java 反射 API 简单地做到这一点：
public void writeKeyboard(Robot bot, String st) {
String upperCase = st.toUpperCase();
for(int i = 0; i < upperCase.length(); i++) {
String letter = Character.toString(upperCase.charAt(i));
String code = "VK_" + letter
Field f = KeyEvent.class.getField(code);
int keyEvent = f.getInt(null);
bot.press(keyEvent);
bot.release(keyEvent);
}
}
我最近写了一个类来做到这一点。它输入每个字符的 Alt 代码，而不是单独找出每个案例的组合键。不是最快的解决方案，但它很简洁，适用于非常广泛的角色。
import java.awt.AWTException;
import java.awt.Robot;
import static java.awt.event.KeyEvent.VK_ALT;
import static java.awt.event.KeyEvent.VK_NUMPAD0;
public class Altbot extends Robot{
Altbot()throws AWTException{}
public void type(CharSequence cs){
for(int i=0;i<cs.length();i++){
type(cs.charAt(i));
}
}
public void type(char c){
keyPress(VK_ALT);
keyPress(VK_NUMPAD0);
keyRelease(VK_NUMPAD0);
String altCode=Integer.toString(c);
for(int i=0;i<altCode.length();i++){
c=(char)(altCode.charAt(i)+'0');
//delay(20);//may be needed for certain applications
keyPress(c);
//delay(20);//uncomment if necessary
keyRelease(c);
}
keyRelease(VK_ALT);
}
}
这就是我设法使用所有可用密钥的方式。创建一个地图并使用方法 fillKeyMap 填充地图。现在您可以使用字符串表示键事件并使用映射将其转换回 KeyEvent 代码。
/** Create map with string values to integer pairs
*/
public static final void fillKeyMap(Map<String, Integer> into) {
try {
Field[] fields = KeyEvent.class.getDeclaredFields();
for(Field f : fields) {
if(f.getName().startsWith("VK_")) { //we only want these fields
int code = ((Integer)f.get(null)).intValue();
into.put(f.getName().substring(3), code);
}
}
} catch(Exception ex) {}
}
这有点像 Kludge，但你可以使用Command 模式来封装 String 中每个字符的击键，然后依次获取每个字符的 Command 并调用该方法。这样做的好处是您只需设置一次地图。缺点是它仍然涉及一堆样板：
public interface Command {
void pressKey(Robot bot);
}
//add a command to the map for each keystroke
commandMap.put("A", new Command() {
void pressKey(Robot bot) {
pressWithShift(KeyEvent.VK_A);
}
});
commandMap.put ("a", new Command() {
void pressKey (Robot bot) {
press (KeyEvent.VK_A);
}
});
commandMap.put("B", new Command() {
void pressKey(Robot bot) {
pressWithShift(KeyEvent.VK_B);
}
});
...
//loads more definitions here
//helper methods
private void pressWithShift (Robot bot, KeyEvent event) {
bot.keyPress (KeyEvent.VK_SHIFT);
press(bot, event);
bot.keyRelase(KeyEvent.VK_SHIFT);
}
private void press(Robot bot, KeyEvent event) {
bot.keyPress(event);
bot.keyRelease(event);
}
然后使用地图：
for (int i = 0; i < st.length(); i++) {
String subString = st.substring(i, i + 1);
commandMap.get(subString).pressKey(bot);
}
我基本上使用了Rich Seller 在他的回答中所做的命令模式，为简洁起见，进行了两个小的修改：
命令界面：
interface Command {
void pressKey(Robot robot);
}
和装饰器（用于修改＃1）：
class ShiftCommand implements Command {
private final Command command;
public ShiftCommand(Command command) {
this.command = command;
}
public void pressKey(Robot robot) {
robot.keyPress(KeyEvent.VK_SHIFT);
command.pressKey(robot);
robot.keyRelease(KeyEvent.VK_SHIFT);
}
@Override
public String toString() {
return "SHIFT + " + command.toString();
}
}
使用这个助手（修改＃2）：
public static int getKeyEvent(Character c) {
Field f = KeyEvent.class.getField("VK_" + Character.toUpperCase(c));
f.setAccessible(true);
return (Integer) f.get(null);
}
注意：我在这里不处理异常，这留给你练习:))
然后使用 for 循环填充命令：
Map<Character, Command> commandMap = new HashMap<Character, Command>();
for (int i = 'a'; i <= 'z'; i++) {
final Character c = Character.valueOf((char) i);
Command pressKeyCommand = new Command() {
public void pressKey(Robot robot) {
int keyEventCode = getKeyEvent(c);
robot.keyPress(c);
robot.keyRelease(c);
}
@Override
public String toString() {
return String.format("%c", c);
}
};
// 'a' .. 'z'
commandMap.put(c, pressKeyCommand);
// 'A' .. 'Z' by decorating pressKeyCommand
commandMap.put(Character.toUpperCase(c), new ShiftCommand(pressKeyCommand));
}
String test = "aaaBBB";
for (int i = 0; i < test.length(); i++) {
System.out.println(commandMap.get(test.charAt(i)));
}
正如预期的那样，这输出：
一种 一种 一种 SHIFT + b SHIFT + b SHIFT + b
接受的答案对我来说似乎很臃肿。这是一个更简洁的解决方案，它有点基于公认的答案。它应该可以处理几乎任何用例。还处理\n（换行）、\t（制表符）和\b（退格），如示例中所示。

robot.keyRelease(keyCode);
if (shift) {
robot.keyRelease(KeyEvent.VK_SHIFT);
}

}
}
}
只要您只使用字母数字字符，您的代码就可以工作，它不适用于像“：”这样的字符。SmartRobot类将处理此问题。
我希望我有 50 个声誉点来评论Adam Paynter解决方案，但还没有......
他的Keyboard课效果很好，但我遇到了非字母键的问题，例如:,\和/。
<ALT>我找到的解决方案是在键入此类键的同时按住<ASCII code>。
首先，我将方法更改doType()为仅按住SHIFT和/或ALT按下，但不是构成 ASCII 码的每个键。差不多，这就是人类使用键盘的方式:)
private void doType(int[] keyCodes, int offset, int length) {
if (length == 0) {
return;
}
robot.keyPress(keyCodes[offset]);
if (keyCodes[offset] == KeyEvent.VK_ALT
|| keyCodes[offset] == KeyEvent.VK_SHIFT) {
doType(keyCodes, offset + 1, length - 1);
robot.keyRelease(keyCodes[offset]);
} else {
robot.keyRelease(keyCodes[offset]);
doType(keyCodes, offset + 1, length - 1);
}
}
然后，我将switch case更改为 passALT和 ASCII 码：
case '\\' :
doType(KeyEvent.VK_ALT, KeyEvent.VK_NUMPAD9,
KeyEvent.VK_NUMPAD2);
case ':' :
doType(KeyEvent.VK_ALT, KeyEvent.VK_NUMPAD5,
KeyEvent.VK_NUMPAD8);
case '/' :
doType(KeyEvent.VK_ALT, KeyEvent.VK_NUMPAD4,
KeyEvent.VK_NUMPAD7);

我遇到过同样的问题。我发现下面的代码是将字符串转换为关键事件的简单方法。似乎大多数人都有非常具体的实现修复来解释小写和大写之间的差异。因为 VK 键不关心大小写，所以将所有内容都转换为大写似乎可以解决问题。
for(int i = 0; i < string.length(); i++){
char c = Character.toUpperCase(s.charAt(i));
KeyEvent ke = new KeyEvent(source, KeyEvent.KEY_PRESSED, System.currentTimeMillis(), 0, (int)c, c);
//do whatever with key event
}
我还想说这适用于字母和数字，但它可能不适用于其他字符。这种技术将重音/反引号翻译成数字键盘 0 ( VK_NUMPAD0)
对 Adam Paynter 的回答稍作修改，因为代码不适用于所有键，例如！、@、#、$ 等（需要先按 VK_SHIFT）

char[] arr = st.toCharArray();
int i = arr.length;
int j = 0;
while (j<i) {
int kcode = (int) arr[j] - 32;
bot.keyPress(kcode);
bot.keyRelease(kcode);
j++;
}
}
它仅适用于小写字母（您可以通过简单的大写测试轻松纠正它）。
对于我正在寻找的东西，它完美地工作:-)
我发现结合 Ryan Hilbert 和 Adam Paynter 的答案给了我最好的结果。它结合了单键的速度和 alt 代码的稳健性。组合代码：
