Bottom Navigation View has been added to version 25 of the Design Support Library. Tried and it's much easier to use now.
But I am facing problem implementing it as per my app requirements. I want to inflate menu resource dynamically and change menu items/titles of the Bottom Navigation view programmatically.
inflateMenu(int menuResource) — Inflate a menu for the bottom navigation view using a menu resource identifier.
According to docs:
inflateMenu: void inflateMenu (int resId) Inflate a menu resource into this navigation view. Existing items in the menu will not be modified or removed. Parameters resId int: ID of a menu resource to inflate
Trying to use this inflateMenu(int resID) method programmatically with navigation view throws exception "Resource not found"
bottomNavigationView.inflateMenu(R.menu.bottom_navigation_menu);
Is it possible to achieve it without any third party libraries?
