NestedScrollView is not working with ViewPager

Here is my code. Can you please suggest or help me. when i try NestedScrollView without ViewPager its working on other page. here is my layout file.

this RelativeLayout can be removed if needed as i have added this

 <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:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#ffffff"
    android:orientation="vertical">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#ffffff"
        android:orientation="vertical">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="50dp"
            android:background="@color/colorAccent">

            <ImageView
                android:id="@+id/back"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:src="@drawable/back"
                android:layout_marginLeft="10dp"
                android:layout_centerVertical="true"/>

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="मेरी प्रोफाइल"
                android:textColor="#ffffff"
                android:textSize="17sp"
                android:layout_centerInParent="true"/>

        </RelativeLayout>

         <androidx.viewpager.widget.ViewPager
                    android:id="@+id/pager"
                    android:layout_width="match_parent"
                    android:layout_height="0dp"
                    app:layout_constraintTop_toBottomOf="@id/tab_layout"
                    app:layout_behavior="@string/appbar_scrolling_view_behavior"


                    android:nestedScrollingEnabled="true"/>

            </androidx.constraintlayout.widget.ConstraintLayout>

        </LinearLayout>

    </androidx.core.widget.NestedScrollView>
</LinearLayout>

Should be solved by setFillViewport (true):

<android.support.v4.widget.NestedScrollView
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:layout_width="match_parent"
android:id="@+id/nest_scrollview"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="mio.kon.yyb.nestedscrollviewbug.ScrollingActivity"
tools:showIn="@layout/activity_scrolling">


    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

And in your activity set:

  NestedScrollView scrollView = (NestedScrollView) findViewById (R.id.nest_scrollview);
    scrollView.setFillViewport (true);
