        binding.root

    }
}

"To many arguments for public fun Fragment.findNavController():NAvcontroller defined in androidx.navigation.fragment" is showing when i hover on findnavcontroller.I am unable to resolve the error on the above bold lines.In this case what should I do?

  • `findNavController(R.id.nav_host_fragment)` and `setupActionBarWithNavController` are methods you'd call in your Activity, not in a Fragment. Can you explain the setup of your app? – ianhanniballake Jan 14 '20 at 06:27

As per the Navigate to a destination documentation, the androidx.navigation.fragment.findNavController you've imported takes no parameters (it finds the parent NavHostFragment of the current Fragment and doesn't need the ID of the NavHostFragment).

The lines you've written, namely findNavController(R.id.nav_host_fragment) and setupActionBarWithNavController() are methods you'd call in an Activity, not in a Fragment.

  • This is quite confusing, why : `val navController = findNavController()` `bottomNavigation.setupWithNavController(navController)` Does not work inside the `onActivityCreated()` of a fragment that has a navHost? – dnhyde Apr 03 '20 at 19:21
