LibGDX如何在调整窗口大小后更新执行元位置？

@Override
public void resize(int width, int height) {
    // 在这里更新元位置
}

@Override
public void resize(int width, int height) {
    viewport.update(width, height);
}

@Override
public void resize(int width, int height) {
    viewport.update(width, height);
    
    for (Actor actor : stage.getActors()) {
        // 更新元素位置和大小
        actor.setPosition(actor.getX() * width / oldWidth, actor.getY() * height / oldHeight);
        actor.setSize(actor.getWidth() * width / oldWidth, actor.getHeight() * height / oldHeight);
    }
    
    oldWidth = width;
    oldHeight = height;
}
