I am attempting to add a DrawerListener to my DrawerLayout   in Activity onCreate: `binding.quickviewDrawer.addDrawerListener(listener)`  but the listener seems to be getting nulled out when I add a breakpoint in DrawerLayout.java   Anyone have an idea why my listener is not persisting?

This is my listener that is in the LoginActivity class

```val listener =  object: DrawerLayout.SimpleDrawerListener() {
    override fun onDrawerOpened(drawerView: View) {
        super.onDrawerOpened(drawerView)
        Toast.makeText(this@LoginActivity, "DrawerOpened!", Toast.LENGTH_SHORT).show()
    }
}```


The error was not in fact Kotlin related at all!  I had layout_gravity="right" on a nested DrawerLayout in XML rather than my FrameLayout.
