1. 建立警报

alert = new Alert("alert");
alert.addCommand(new Command("Ok", Command.OK, 0));
alert.addCommand(new Command("Cancel", Command.CANCEL, 0););
alert.setCommandListener(this);
alert.setTimeout(Alert.FOREVER);

载于CommandAction。

 if (displayable == alert) {
        if (command == cancelCommand) {
                //user denied
        } else if (command == okCommand1) {
              //user accepts
        }
    }
