Всем привет. делаю боковое меню drawerLayout.addDrawerListener(object: DrawerLayout.SimpleDrawerListener() {

override fun onDrawerStateChanged(newState: Int) {
super.onDrawerStateChanged(newState)
loge("!!!!!!!!! $newState")
}

override fun onDrawerSlide(drawerView: View, slideOffset: Float) {
super.onDrawerSlide(drawerView, slideOffset)
loge("+++++++++")
}

override fun onDrawerClosed(drawerView: View) {
super.onDrawerClosed(drawerView)
loge("---------------")
}

override fun onDrawerOpened(drawerView: View) {
super.onDrawerOpened(drawerView)
loge("***********")
}
})

drawerLayout.setScrimColor(Color.TRANSPARENT)
drawerLayout.openDrawer(GravityCompat.END)
