First Add support v7 library in your project then in xml file put this.
<android.support.v7.widget.RecyclerView
android:id="@+id/my_recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v7.widget.RecyclerView>
Then in your fragment put these lines.
scheduler_day_view_horizontal_recyclerview = (RecyclerView) v.findViewById(R.id.my_recycler_view);
layoutManager = new LinearLayoutManager(context, LinearLayoutManager.HORIZONTAL, false);
scheduler_day_view_horizontal_recyclerview.setLayoutManager(layoutManager);
scheduler_day_view_horizontal_recyclerview.setItemAnimator(new DefaultItemAnimator());
scheduler_day_view_horizontal_recyclerview.setHasFixedSize(true);
Then set adapter to the RecyclerView.
