android - navController.addOnDestinationChangedListener 未提供导航图中使用的活动项

Question

我正在尝试在导航菜单中调用注销选项，并且调用工作正常，并且导航到登录屏幕。但是我想清除存储在共享首选项中的登录详细信息，为此，我尝试了`

navController.addOnDestinationChangedListener { controller, destination, arguments ->

            Log.d("TAG", "label: "+destination.label)
            
        }`

但它没有给出注销菜单 id 甚至标签，当我点击注销菜单时它给出了 nav_home 标签/id

这是我的菜单项类
