无法在Java中使用机器人按Window + L.

Question

我正在使用Robot类来模拟Java中的按键。但我无法按下Window键+ L，虽然我可以单独按下它们。这是我的代码：

private void pressKey()
{
    Robot r=new Robot();
    robot.keyPress(KeyEvent.VK_WINDOWS);
    robot.keyPress(KeyEvent.VK_L);
    robot.keyRelease(KeyEvent.VK_WINDOWS);
    robot.keyRelease(KeyEvent.VK_L);
}

Answer 1

请改为尝试：

Runtime.getRuntime().exec("rundll32 user32.dll,LockWorkStation");

Answer 2

尝试：

private void pressKey(){
   Robot r=new Robot();
   robot.keyPress(KeyEvent.VK_WINDOWS);
   robot.keyPress(KeyEvent.VK_L);
   robot.keyRelease(KeyEvent.VK_L);
   robot.keyRelease(KeyEvent.VK_WINDOWS);
}

Answer 3

试试这个：

robot.keyPress(KeyEvent.VK_WINDOWS);
robot.delay(100);
robot.keyPress(KeyEvent.VK_L);
robot.delay(200);
robot.keyRelease(KeyEvent.VK_L);
robot.delay(100);
robot.keyRelease(KeyEvent.VK_WINDOWS);
