使用java.awt.Robot键入String

Question

我已经知道如何使用java.awt.Robot键入单个字符keyPress,如下所示.如何在文本框中一次输入一个完整的预定义String值？

robot.keyPress(KeyEvent.VK_1);
robot.keyPress(KeyEvent.VK_1);
robot.keyPress(KeyEvent.VK_1);  
// instead, enter String x = "111"

Answer 1

常见的解决方案是使用剪贴板:

String text = "Hello World";
StringSelection stringSelection = new StringSelection(text);
Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
clipboard.setContents(stringSelection, stringSelection);

Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_CONTROL);

Answer 2

你需要"输入"这个角色,这是一个按下并释放动作......

robot.keyPress(KeyEvent.VK_1);  
robot.keyRelease(KeyEvent.VK_1);  

现在你可以复制并粘贴三次,但我只是把它放在一个循环中

从Java 7开始，您还可以使用KeyEvent.getExtendedKeyCodeForChar（c）。仅适用于小写字母的示例可能是：

void sendKeys(Robot robot, String keys) {
    for (char c : keys.toCharArray()) {
        int keyCode = KeyEvent.getExtendedKeyCodeForChar(c);
        if (KeyEvent.CHAR_UNDEFINED == keyCode) {
            throw new RuntimeException(
                "Key code not found for character '" + c + "'");
        }
        robot.keyPress(keyCode);
        robot.delay(100);
        robot.keyRelease(keyCode);
        robot.delay(100);
    }
}
