Highlighting a menu item in BottomNavigationView without invoking onNavigationItemSelected method

Question

I have a BottomNavigationView in my activity with onNavigationItemSelected listener.

I have two questions:

1. Does setSelectedItemId method invoke the onNavigationItemSelected method? The documentation says this method behaves as if the menu item was tapped, my observation is yes.

2. If yes, how to highlight a menu item without invoking onNavigationItemSelected?

Answer 1

1. Yes, BottomNavigationView.setSelectedItemId(int itemId) triggers onNavigationItemSelected(MenuItem item).

2. Use BottomNavigationView.getMenu().getItem(int index) or BottomNavigationView.getMenu().findItem(int id), then call MenuItem.setChecked(boolean checked) to highlight a menu item without triggering onNavigationItemSelected(MenuItem item).
