        android:layout_height="wrap_content"
        android:id="@+id/noFriendsTitle"
        android:layout_marginTop="@dimen/marginTop"
        android:layout_centerHorizontal="true"
        android:visibility="gone"
        android:text="@string/no_friends_title"/>
    <ProgressBar
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/progressBarGetFriends"
        android:layout_centerInParent="true"/>
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/mainFriendsRelative"
        android:paddingTop="@dimen/marginTopSmall"
        android:paddingBottom="@dimen/marginTopSmall"
        android:visibility="invisible">
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginStart="@dimen/paddingStart"
            android:id="@+id/lastConversationTitle"
            android:text="@string/friends_important_title"/>
        <android.support.v7.widget.RecyclerView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/lastChatFriendsRecyclerView"
            android:layout_below="@+id/lastConversationTitle"
            android:layout_marginTop="@dimen/marginTopSmall"/>
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginStart="@dimen/paddingStart"
            android:layout_below="@+id/lastChatFriendsRecyclerView"
            android:layout_marginTop="@dimen/marginTopSmall"
            android:id="@+id/allFriendsTitle"
            android:text="@string/friends_all"/>
        <android.support.v4.widget.SwipeRefreshLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/friendSwipeToRefresh"
            android:layout_below="@+id/allFriendsTitle"
            android:layout_marginTop="@dimen/marginTopSmall">
            <android.support.v7.widget.RecyclerView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:id="@+id/friendsRecyclerView"
                android:scrollbars="vertical"/>
        </android.support.v4.widget.SwipeRefreshLayout>
    </RelativeLayout>
</RelativeLayout>

My fragment code

private void setLastConversationFriendsRecycler(RecyclerView lastConversationRecyclerView, List<Edge<Friends>> friends){
    lastConversationList.addAll(friends);
    LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
    lastConversationRecyclerView.setHasFixedSize(true);
    lastConversationRecyclerView.setLayoutManager(layoutManager);
    lastConversationAdapter = new FriendsAdapter(getActivity(), lastConversationList, lastConversationRecyclerView);
    lastConversationRecyclerView.setAdapter(lastConversationAdapter);
}

private void setFriendsRecycler(RecyclerView friendsRecyclerView, List<Edge<Friends>> friends){
    friendsList.addAll(friends);
    LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
    friendsRecyclerView.setHasFixedSize(true);
    friendsRecyclerView.setLayoutManager(layoutManager);
    friendsAdapter = new FriendsAdapter(getActivity(), friendsList, friendsRecyclerView);
    friendsAdapter.setOnLoadMoreListener(friendsListener);
    friendsRecyclerView.setAdapter(friendsAdapter);
}

I also try different combination with setNestedScrollingEnabled, but result was the same.
