Answer 1

You can re-inflate NavigationViewat runtime with 2 lines of code using public method inflateMenu. In this example i re-inflate with new_navigation_drawer_items.xml

navigationView.getMenu().clear(); //clear old inflated items.
navigationView.inflateMenu(R.menu.new_navigation_drawer_items); //inflate new items.
