LibGDX阶段坐标在窗口大小调整时更改

在这个阶段制作基本舞台和基本演员时,比如说windowsize 480×320,一切都还可以.我可以点击我的演员,它会回应.但是当我调整窗口大小时,说600×320,一切看起来都正确,但我的clicklistener不再工作了.此外,舞台坐标被移动或搞砸了.

我使用以下代码：

stage.addListener(new InputListener() {
    public boolean touchDown(InputEvent event,float x,float y,int pointer,int button) {

        //determine if actor was hit
        System.out.println(stage.hit(x,y,true));
        return true;
    }
});

另外,我正在调整舞台摄像机视口的大小以对应窗口：

stage.getCamera().viewportWidth = Gdx.graphics.getWidth();
    stage.getCamera().viewportHeight = Gdx.graphics.getHeight();

因此,在调整大小时,我会在屏幕上获得所需的效果,但是我的听众没有回应 – 演员似乎对我点击的位置有“偏移”.我究竟做错了什么？我应该根据调整大小移动我的演员或我的摄像头,还是缩放我的摄像头？有人可以向我解释一下吗？

非常感谢提前！

编辑：下面是我班级的完整代码.
