Navigate to fragment on FAB click (Navigation Architecture Components)
Ran into this issue today and I found out that there is a simple and elegant solution for it.
val navController = findNavController(R.id.navHostFragment)
fabAdd.setOnClickListener {
navController.navigate(R.id.yourFragment)
}
This takes care of the navigation. Then you must control the visibility of your BottomAppBar
inside your Activity
.
You could have your BottomAppBar
in MainActivity
and access your FloatingActionButton
in your fragment as follows
activity?.fab?.setOnClickListener {
/*...*/
findNavController().navigate(R.id.action_firstFragment_to_secondFragment, mDataBundle)
}
You could hide the BottomAppBar
from another activity as follows
(activity as AppCompatActivity).supportActionBar?.hide()
Make sure you .show()
the BottomAppBar
while returning to previous fragment
