推荐答案

您应该在窗体上侦听带有#的键代码的KeyPress或keyReleased事件，并在按下#键时退出应用程序.

You should listen for a KeyPress or keyReleased event on the form with the keycode for # and exitApplication when the # key is pressed.

protected void keyPressed(int key)
{
    System.out.println("Key Pressed");

    if(key==52) //change 52 to match keyCode for # key 
    {
      Display.getInstance().exitApplication();
    }
}
