RecyclerView Laggy inside NestedScrollView/LinearLayout

Before digging into the code, I've already checked the following questions:

1. How to use RecyclerView inside NestedScrollView?
2. Recyclerview inside Nested Scrollview scroll but does not fast scroll like normal Recyclerview or Nested Scrollview
3. RecyclerView inside a ScrollView/NestedScrollView does not scroll properly

None of the aforementioned questions has worked with me. The RecyclerView is too laggy when scrolling.

I have a NestedScrollview and a LinearLayout as a main Layout for the NestedScrollview. Layout's code is:

<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" xmlns:fbutton="http://schemas.android.com/apk/res-auto" > <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" android:gravity="center" > <android.support.v7.widget.RecyclerView android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="@dimen/frag_misc_rv_margin_top" android:scrollbars="none" android:nestedScrollingEnabled="false" android:id="@+id/frag_showcase_promotion_recyclerview"/> </LinearLayout> </android.support.v4.widget.NestedScrollView> 

The code is:

mPromotionsRv.setLayoutManager(new LinearLayoutManager(getActivity(),LinearLayoutManager.HORIZONTAL,false)); mPromotionsRv.setNestedScrollingEnabled(false); mPromotionsAdapter = new ShowcasePromotionRvAdapter(getActivity(), mPromotionsItems); mPromotionsAdapter.setOnItemClickListener(new ShowcasePromotionListener() { @Override public void onClick(View view, int position) { ItemPromotion mPromotion = mPromotionsItems.get(position); try{ recordPromotionClick(mPromotion.getId()); view.getContext().startActivity(new Intent(Intent.ACTION_VIEW).setData(Uri.parse(mPromotion.getPromotion_link()))); } catch (Exception e){ e.printStackTrace(); } } }); mPromotionsRv.setAdapter(mPromotionsAdapter); SnapHelper snapHelperStart = new GravitySnapHelper(Gravity.START); snapHelperStart.attachToRecyclerView(mPromotionsRv); RecyclerView.ItemAnimator animator = mPromotionsRv.getItemAnimator(); if (animator instanceof SimpleItemAnimator) { ((SimpleItemAnimator) animator).setSupportsChangeAnimations(false); }
