KeyListener问题，在一个函数中监听keypress

Question

我正在为DS模拟器编写一个口袋妖怪教练。我希望程序做的是在运行机器人的时候，花点时间听一下可能暂停训练器的按键，如果没有按下任何东西，那就继续吧。

所以我所做的是在机器人按左/右键完成后实现一个关键事件，但它似乎没有检测到按键。

计划代码：

package frame;

public class start {
    //Global Variables
    static int time;
    static int waitTime;
    public static void main (String[] args) throws InterruptedException, AWTException, IOException {
        trainerMenu();
    }

    public static void trainerMenu() throws InterruptedException, AWTException, IOException {
        Scanner timeToTrain = new Scanner(System.in);
        Scanner wait = new Scanner(System.in);      
        System.out.println("Welcome to xR34P3Rx's PokeMon Trainer!");
        System.out.print("Enter rounds to train your pokemon, (Each round takes aprox. 47 sec. ): ");
        time = timeToTrain.nextInt();
        System.out.print("How much time do you need to get to your emulator: ");
        waitTime = wait.nextInt();
        goTrain();
    }

    public static void goTrain() throws InterruptedException, AWTException, IOException {
        while (time != 0) {
            walkRight();
            walkLeft();
            time--;
        }
        System.out.println("Training Complete!\nPress any key to return to the menu...");
        System.in.read();
        trainerMenu();
    }

    public static void walkRight() throws InterruptedException, AWTException {
        Thread.sleep(waitTime);
        int steps = 79;

        //Robot 1
        try {
            while (steps!=0) {
                Robot robot = new Robot();

                robot.keyPress(KeyEvent.VK_RIGHT);
                steps--;
                Thread.sleep(275);
            }
        } finally {}
        Robot end = new Robot();
        end.keyRelease(KeyEvent.VK_RIGHT);

        //Pause
        new KeyPressed() {
            public void keyTyped(KeyEvent e) {}         
            public void KeyPressed(KeyEvent e) {
                System.out.println("Key pressed code=" + e.getKeyCode() + ", char=" + e.getKeyChar());
            }
        };
    }

    public static void walkLeft() throws InterruptedException, AWTException {
        Thread.sleep(waitTime);
        int steps = 79;

        //Robot 1
        try {
            while (steps!=0) {
                Robot robot = new Robot();

                robot.keyPress(KeyEvent.VK_LEFT);
                steps--;
                Thread.sleep(275);
            }
        } finally {}
        Robot end = new Robot();
        end.keyRelease(KeyEvent.VK_LEFT);

        new KeyPressed() {
            public void keyTyped(KeyEvent e) {}

            public void KeyPressed(KeyEvent e) {
                System.out.println("Key pressed code=" + e.getKeyCode() + ", char=" + e.getKeyChar());
            }
        };
    }
}

然后我尝试为KeyListener创建一个新类，并在结束Robot KeyEvent之后添加new KeyPressed();来调用该侦听器，但它没有响应。

添加了new KeyPressed();：

public static void walkLeft() throws InterruptedException, AWTException {
    Thread.sleep(waitTime);
    int steps = 79;

    //Robot 1
    try {
        while (steps != 0) {
            Robot robot = new Robot();

            robot.keyPress(KeyEvent.VK_LEFT);
            steps--;
            Thread.sleep(275);
        }
    }finally {}
    Robot end = new Robot();
    end.keyRelease(KeyEvent.VK_LEFT);

    //Pause
    new KeyPressed();
}

新KeyPressed KeyListener课程：

package frame;

public class KeyPressed implements KeyListener{

    @Override
    public void keyPressed(KeyEvent arg0) {
        // TODO Auto-generated method stub
        arg0.getKeyChar();
        if (arg0.getKeyChar() == 'z') {
            System.out.println("You pressed 'Z'");
        }
    }

    @Override
    public void keyReleased(KeyEvent arg0) {}
    @Override
    public void keyTyped(KeyEvent arg0) {}

}

到目前为止，没有一个有效，但我认为它可能是我的位置，或者我没有给自己足够的时间来按键，因为它唯一的延迟是275毫秒。

更新：收听任何按键：

package frame;

public class KeyPressed implements KeyListener{
    @Override
    public void keyPressed(KeyEvent arg0) {
        char pressed = arg0.getKeyChar();
        System.out.println("You pressed" + pressed);
    }

    @Override
    public void keyReleased(KeyEvent arg0) {}
    @Override
    public void keyTyped(KeyEvent arg0) {}

}
