I am trying to use navigation controller in Android
as you can see in the image above, I set the label
attribute of my destination to be 'Home'.
and this label, will show like title in my toolbar. can I change that label programatically ? because I want to set my toolbar title dynamically.
I have tried to change the toolbar title using toolbar.title = "some title here"
but it will always be overlapped the title from that label.
so how to solve this ?
Do it in your activity like below it's worked for me:
setSupportActionBar(toolbar)
val navController = findNavController(R.id.nav_controller_fragment)
val appBarConfiguration = AppBarConfiguration(navController.graph)
setupActionBarWithNavController(navController, appBarConfiguration)
navController.addOnDestinationChangedListener { controller, destination, arguments ->
when (destination.id) {
R.id.mainFragment -> toolbar.title = "ok"
else -> {
toolbar.title = "General"
}
}
}
or if you want to change from your fragment do like below:
override fun onStart() {
super.onStart()
(activity as MainActivity).toolbar.title = "changed"
}
