BottomNavigationView switching between activities - solutions appear deprecated?

Question

I am using a BottomNavigationBar and as per recent blogs and research, it seems the best way to flick between activities using this bar is to use the setInNavigationItemSelectedListener.

The issue is - this is deprecated.

setOnNavigationItemSelectedListener(com.google.android.material.bottomnavigation.BottomNavigationView.OnNavigationItemSelectedListener)' is deprecated

Recent articles suggest this is the way to allow changing between activities via a BottomNavigationBar and therefore I am not sure of alternative.

The deprecation doesn't appear to offer a good alternative that is safe to use. Can somebody suggest what would be non deprecated approach?

Answer 1

You need to use setOnItemSelectedListener()

Like this

bottomBar.setOnItemSelectedListener { menuItem ->
  when (menuItem.itemId) {
    R.id.home -> {
      return@setOnItemSelectedListener true
    }

    R.id.profile -> {
      return@setOnItemSelectedListener true
    }

    R.id.cart -> {
      return@setOnItemSelectedListener true
    }

  }
  false
}
