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++; } }
我基本上是在用荣耀的switch声明。简单快捷：
switch
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; case 'b': doType(VK_B); break; case 'c': doType(VK_C); break; case 'd': doType(VK_D); break; case 'e': doType(VK_E); break; case 'f': doType(VK_F); break; case 'g': doType(VK_G); break; case 'h': doType(VK_H); break; case 'i': doType(VK_I); break; case 'j': doType(VK_J); break; case 'k': doType(VK_K); break; case 'l': doType(VK_L); break; case 'm': doType(VK_M); break; case 'n': doType(VK_N); break; case 'o': doType(VK_O); break; case 'p': doType(VK_P); break; case 'q': doType(VK_Q); break; case 'r': doType(VK_R); break; case 's': doType(VK_S); break; case 't': doType(VK_T); break; case 'u': doType(VK_U); break; case 'v': doType(VK_V); break; case 'w': doType(VK_W); break; case 'x': doType(VK_X); break; case 'y': doType(VK_Y); break; case 'z': doType(VK_Z); break; case 'A': doType(VK_SHIFT, VK_A); break; case 'B': doType(VK_SHIFT, VK_B); break; case 'C': doType(VK_SHIFT, VK_C); break; case 'D': doType(VK_SHIFT, VK_D); break; case 'E': doType(VK_SHIFT, VK_E); break; case 'F': doType(VK_SHIFT, VK_F); break; case 'G': doType(VK_SHIFT, VK_G); break; case 'H': doType(VK_SHIFT, VK_H); break; case 'I': doType(VK_SHIFT, VK_I); break; case 'J': doType(VK_SHIFT, VK_J); break; case 'K': doType(VK_SHIFT, VK_K); break; case 'L': doType(VK_SHIFT, VK_L); break; case 'M': doType(VK_SHIFT, VK_M); break; case 'N': doType(VK_SHIFT, VK_N); break; case 'O': doType(VK_SHIFT, VK_O); break; case 'P': doType(VK_SHIFT, VK_P); break; case 'Q': doType(VK_SHIFT, VK_Q); break; case 'R': doType(VK_SHIFT, VK_R); break; case 'S': doType(VK_SHIFT, VK_S); break; case 'T': doType(VK_SHIFT, VK_T); break; case 'U': doType(VK_SHIFT, VK_U); break; case 'V': doType(VK_SHIFT, VK_V); break; case 'W': doType(VK_SHIFT, VK_W); break; case 'X': doType(VK_SHIFT, VK_X); break; case 'Y': doType(VK_SHIFT, VK_Y); break; case 'Z': doType(VK_SHIFT, VK_Z); break; case '`': doType(VK_BACK_QUOTE); break; case '0': doType(VK_0); break; case '1': doType(VK_1); break; case '2': doType(VK_2); break; case '3': doType(VK_3); break; case '4': doType(VK_4); break; case '5': doType(VK_5); break; case '6': doType(VK_6); break; case '7': doType(VK_7); break; case '8': doType(VK_8); break; case '9': doType(VK_9); break; case '-': doType(VK_MINUS); break; case '=': doType(VK_EQUALS); break; case '~': doType(VK_SHIFT, VK_BACK_QUOTE); break; case '!': doType(VK_EXCLAMATION_MARK); break; case '@': doType(VK_AT); break; case '#': doType(VK_NUMBER_SIGN); break; case '$': doType(VK_DOLLAR); break; case '%': doType(VK_SHIFT, VK_5); break; case '^': doType(VK_CIRCUMFLEX); break; case '&': doType(VK_AMPERSAND); break; case '*': doType(VK_ASTERISK); break; case '(': doType(VK_LEFT_PARENTHESIS); break; case ')': doType(VK_RIGHT_PARENTHESIS); break; case '_': doType(VK_UNDERSCORE); break; case '+': doType(VK_PLUS); break; case '\t': doType(VK_TAB); break; case '\n': doType(VK_ENTER); break; case '[': doType(VK_OPEN_BRACKET); break; case ']': doType(VK_CLOSE_BRACKET); break; case '\\': doType(VK_BACK_SLASH); break; case '{': doType(VK_SHIFT, VK_OPEN_BRACKET); break; case '}': doType(VK_SHIFT, VK_CLOSE_BRACKET); break; case '|': doType(VK_SHIFT, VK_BACK_SLASH); break; case ';': doType(VK_SEMICOLON); break; case ':': doType(VK_COLON); break; case '\'': doType(VK_QUOTE); break; case '"': doType(VK_QUOTEDBL); break; case ',': doType(VK_COMMA); break; case '<': doType(VK_SHIFT, VK_COMMA); break; case '.': doType(VK_PERIOD); break; case '>': doType(VK_SHIFT, VK_PERIOD); break; case '/': doType(VK_SLASH); break; case '?': doType(VK_SHIFT, VK_SLASH); break; case ' ': doType(VK_SPACE); 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。
