        fragmentTransaction.replace(R.id.fragmentContainer,driverListFragment);
        fragmentTransaction.addToBackStack("driverListFragment");
        fragmentTransaction.commit();
    }

}

I want to show my RecyclerView list in fragment instead of an activity, when i call fragment in activity it simply showing me blank activity however, there's no error in code. How can i achieve this task or where i am doing a mistake?

In `activity_driver_list`, you need to add `android:orientation="vertical"` to the ``. `LinearLayout`'s have a horizontal orientation by default, and with your toolbar – which presumably has `match_parent` width – the `RecyclerView` is being pushed out the side, off-screen. — Mike M., Apr 10 '20 at 00:23
