Answer 1

Why don't you make your base activity implements NavigationView.OnNavigationItemSelectedListener

Then add these those calls

 DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawer.setDrawerListener(toggle);
        toggle.syncState();

        NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
        navigationView.setItemIconTintList(null);
        navigationView.setNavigationItemSelectedListener(this);

So you don't need to implement it from fragment. You just replace or add the fragments.
