                android:scaleType="fitCenter"
                android:src="@drawable/profile" />

            <TextView
                android:id="@+id/ProfileText"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="bottom|center_horizontal"
                android:layout_marginBottom="10dp"
                android:fontFamily="@font/roboto_regular"
                android:textColor="@color/topbartextcolor"
                android:text="@string/profile"
                android:textSize="16sp" />
        </androidx.cardview.widget.CardView>
    </LinearLayout>

    <FrameLayout
        android:id="@+id/fragmentContainer"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/categLinear"
        android:layout_marginTop="15dp"
        tools:listitem="@layout/inboxrecycler" />

    <ProgressBar
        android:id="@+id/progressBar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/categLinear"
        android:background="@color/main_gray"
        android:indeterminate="true"
        android:indeterminateTint="@color/purple"
        android:padding="140dp"
        android:visibility="visible" />

</RelativeLayout>

And it looks like this :

There is a fragment inside the FrameLayout and recyclerview inside that fragment. So I want to collapse theese three cardviews to a tab layout when I scroll and reappear cardviews when I scroll to top, but I am not that good at material design. How may I do that?
