Question

    android:layout_height="match_parent"
    android:background="#eeeeee"
    android:clickable="true"
    >
    <ProgressBar

        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:layout_marginLeft="2dp"
        android:layout_marginRight="2dp"

    <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

Change ScrollView to NestedScrollView .

In order this to work, you need to have RecyclerView with height wrap_content inside NestedScrollView and you need to set recyclerView.setNestedScrollingEnabled(false) from code.

Answer 2

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.
