set Recycler View Visible row count max 3 items even though it has more items

Question

Stuck in this problem about RecyclerView Visible item count Requirement :- RecyclerView has 3+ items but ,need to show 3 items (other items can be reached through scrolling) RecyclerView has <=3 items , need to show the full items

Recyclerview set adapter code

     cardoptionlist.clear();
    cardoptionlist.addAll(savedcards);
    cardoptionlist.add(new CardModel(true));

    if (cardOptionAdapter == null) {
        cardOptionAdapter = new CardOptionAdapter(getActivity(), cardoptionlist, this);
    }


    if (rcv_card_options.getLayoutManager() == null) {

        rcv_card_options.setLayoutManager(new LinearLayoutManager(getActivity()));

    }

    rcv_card_options.addItemDecoration(new DividerItemDecoration(getActivity(), LinearLayoutManager.VERTICAL, 0, false));
    rcv_card_options.setItemAnimator(new DefaultItemAnimator());

    rcv_card_options.setHasFixedSize(true);
    rcv_card_options.setItemViewCacheSize(20);
    rcv_card_options.setDrawingCacheEnabled(true);
    rcv_card_options.setAdapter(cardOptionAdapter);

Recyclerview Xml file

      <android.support.v7.widget.RecyclerView
        android:id="@+id/rcv_card_options"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/rounded_white_app_color_border_8dp"
        android:paddingBottom="2dp"

        android:paddingLeft="8dp"
        android:paddingRight="8dp"
        android:paddingTop="2dp"

        >

Thanks in advance

@Override public void onBindViewHolder(ImageViewHolder imageViewHolder, int position) { setHeight(imageViewHolder.mainParantView); } – Umesh AHIR Oct 24 '17 at 10:51
