MaterialDividerItemDecoration

public class MaterialDividerItemDecoration
extends RecyclerView.ItemDecoration

java.lang.Object
↳	androidx.recyclerview.widget.RecyclerView.ItemDecoration
	↳	com.google.android.material.divider.MaterialDividerItemDecoration

MaterialDividerItemDecoration is a RecyclerView.ItemDecoration, similar to a DividerItemDecoration, that can be used as a divider between items of a LinearLayoutManager. It supports both HORIZONTAL and VERTICAL orientations.

     dividerItemDecoration = new MaterialDividerItemDecoration(recyclerView.getContext(),
             layoutManager.getOrientation());
     recyclerView.addItemDecoration(dividerItemDecoration);
