Scrolling of multiple recycler view in an activity. (how to make it smooth)

Question

I have 2 recyclerviews in my activity 1st one is horizontally scrollable and the 2nd one is vertically scrollable. (XML code given below) But the scrolling is not smooth.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ll1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#eeeeee"
    android:clickable="true"
    >
    <ProgressBar
        android:id="@+id/progressBarCircularIndetermininatesearch"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:indeterminateTintMode="src_atop"
        android:indeterminateTint="#f44336"
        android:layout_centerInParent="true"/>

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/progressbacklin"
        android:scrollbars="none"
        >
        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">
    <android.support.v7.widget.RecyclerView
        android:id="@+id/videolist"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="2dp"
        android:layout_marginRight="2dp"
        android:layout_alignParentTop="true"
        android:scrollbars="none"
        />


    <android.support.v7.widget.RecyclerView
        android:id="@+id/list"
        android:layout_below="@+id/videolist"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="2dp"
        android:layout_marginRight="2dp"
        android:scrollbars="none"
        />
        </RelativeLayout>
</ScrollView>
    <LinearLayout
        android:id="@+id/progressbacklin"
        android:layout_above="@+id/adViewsearch"
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:layout_marginBottom="90dp"
        android:layout_marginTop="5dp"
        android:background="@drawable/white"
        android:gravity="center"
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true"
        >
        <ProgressBar
            android:id="@+id/progressBarCircularIndetermininate"
            android:layout_width="24dp"
            android:layout_height="24dp"
            android:indeterminateTintMode="src_atop"
            android:indeterminateTint="#f44336"
            android:layout_centerInParent="true"/>
    </LinearLayout>
    <com.google.android.gms.ads.AdView
        xmlns:ads="http://schemas.android.com/apk/res-auto"
        android:id="@+id/adViewsearch"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        ads:adSize="SMART_BANNER"
        ads:adUnitId="@string/banner_ad_unit_id" />

</RelativeLayout>

i use

setNestedScrollingEnabled(false); 

for both recycler view.

Any ideas to implement this with a smooth scrolling?

Answer 1

How i solved this problem is by using a single Recycler view instead of two and setting up the other (1st recycler view in question) recycler view as first item of it. Now it works perfect and scrolling smoothly.
