How to scroll to a particular position in recyclerview inside scrollview?

Question

I have searched a lot regarding my query and none of them was useful. I have a recyclerview and some static data inside a scroll view which is inside a root parentlayout as show below.

I have set -

scrollview.scrollto(0,0); 

because everytime i open the activity it jumps to the recyclerview firstitem and it skips out the static data above the recyclerview.

recyclerview.setNestedScrollingEnabled(false);  recyclerview.setfocusable(false); 

for smoothscroll.

the problem is with-

layoutmanager.scrollToPositionWithOffset(pos,0); 

it is not working. I have set the aboveline after setting adapter to recyclerview. Also tried with NestedScrollView but in vain.

although I have used

layoutmanager.scrollToPosition(pos); 

For those who skip the code, i have set match_parent to ScrollView and fillviewport to true.

Here is my layout.

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout     xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto"     xmlns:tools="http://schemas.android.com/tools"     android:id="@+id/bottomsheet"     android:layout_width="match_parent"     android:layout_height="match_parent"     tools:context="com.inkdrops.khaalijeb.BrandCouponActivity">      <RelativeLayout         android:id="@+id/inclusionviewgroup"         android:layout_width="match_parent"         android:layout_height="match_parent">          <static data/>          <ScrollView             android:id="@+id/scrollviewmain"             android:layout_width="match_parent"             android:layout_height="match_parent"             android:layout_below="@+id/one"             android:fillViewport="true"             android:scrollbars="none"             android:layout_above="@+id/donelayout">               <staticdata/>                  <TextView                     android:id="@+id/dealstext"                     android:layout_width="wrap_content"                     android:layout_height="wrap_content"                     android:layout_below="@+id/card1"                     android:layout_marginTop="10dp"                     android:layout_marginLeft="10dp"                     android:textSize="16sp"                     android:text="Deals &amp; Coupons"                     android:textColor="#444444" />                  <RelativeLayout                     android:id="@+id/recyclerlayout"                     android:layout_width="match_parent"                     android:layout_height="wrap_content"                     android:layout_below="@+id/dealstext"                     android:layout_marginTop="5dp"                     android:layout_marginLeft="8dp"                     android:layout_marginRight="8dp"                     android:background="@color/colorbackground">                      <android.support.v7.widget.RecyclerView                         android:id="@+id/coupon_rec_view"                         android:layout_width="match_parent"                         android:layout_height="wrap_content"                         android:background="@color/colorbackground"                         android:visibility="visible"/>                   </RelativeLayout>                  <statisdata>               </RelativeLayout>          </ScrollView>          include layout="@layout/activity_coupons"             android:visibility="gone"             />      </RelativeLayout>  </RelativeLayout>

Need to scroll ScrollView by getting top position of RecyclerView's child :

float y = recyclerView.getY() + recyclerView.getChildAt(selectedPosition).getY();     scrollView.smoothScrollTo(0, (int) y);
