Dynamic ActionBar title from a Fragment using AndroidX Navigation

Question

I am using the new Navigation component from Android Jetpack.

The root Activity setup is quite simple:

override fun onCreate(savedInstanceState: Bund         


        

Answer 1

On trying the activity's title it seems to override the title for fragment. Being on safe side you must put on onResume.

override fun onResume() {
    super.onResume()
    activity?.toolbar.title = "YOUR_TITLE_HERE"
}

it works for me !

Note : Must have Toolbar Widget in activity

Add toolbar like this in your activity's xml
