How to hide the default fragment actionBar create our own actionBar in android & kotlin

Question

I have an android app with bottom navigation containing 3 fragments and all have their own actionBar by default. I want to hide all the default actionBar of three fragments and create my own actionbar with many options. I am using Kotlin.

Answer 1

I have solved the problem.

val appBarConfiguration = AppBarConfiguration(setOf( R.id.navigation_home, R.id.navigation_messages, R.id.navigation_profile)) 
setupActionBarWithNavController(navController, appBarConfiguration)

Just remove the above two lines from the main activity and your problem is solved.
