java - 来自剪贴板类型的机器人粘贴 "v"

Question

(OSX) 我正在尝试粘贴字符串“Hello World!”从我的剪贴板到一个单独的应用程序。字符串被复制到我的剪贴板，我可以手动粘贴它，但机器人只键入“v”，而不是同时按下 VK_META + VK_V 键。

public static void sendString() throws Exception {
    Thread.sleep(3000);
    String text = "Hello World!";
    StringSelection stringSelection = new StringSelection(text);
    Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
    clipboard.setContents(stringSelection, stringSelection);
    try {
        Robot robot = new Robot();
        robot.keyPress(KeyEvent.VK_META);
        robot.keyPress(KeyEvent.VK_V);
        robot.keyRelease(KeyEvent.VK_V);
        robot.keyRelease(KeyEvent.VK_META);
    } catch(java.awt.AWTException awte) {
        System.out.println("AWTException");
    }
}

Answer 1

为了确保命令的顺序，请在命令之间添加延迟:

try{
    Robot robot = new Robot();
    robot.keyPress(KeyEvent.VK_META);
    robot.delay(500);                    // 200~500
    robot.keyPress(KeyEvent.VK_V);
    robot.keyRelease(KeyEvent.VK_V);
    robot.keyRelease(KeyEvent.VK_META);
} catch(java.awt.AWTException awte) {
    System.out.println("AWTException");
}
