CollapsingToolBarLayout and NestedScrollView smooth scroll issues

Question

I'm using CoordinatorLayout with CollapsingToolBar and NestedScrollView. The elements are being inserted via RecyclerView. Whenever I try to scroll up or down the scroll isn't smooth, it's very slow, regardless the velocity of the gesture. I tried the solution here but it didn't solve my problem. So I have no idea what causes this problem or how to solve it.

Here is my xml layout

            </LinearLayout>

            <FrameLayout

                android:layout_marginTop="10dp"
                android:orientation="horizontal">

            </FrameLayout>

        </RelativeLayout>

    </android.support.v4.widget.NestedScrollView>

</android.support.design.widget.CoordinatorLayout>

The FrameLayout is a place holder for different fragments with different scrollable RecyclerViews. Thanks in advance.

Layout structure seems okay. So the problem might be here. android:src="@drawable/logo".

Try moving it to drawable-nodpi directory. Also loading with Picasso / Glide will improve perfomance.

Thank you for the reply, but moving the image to another folder didn't solve the problem. – Keselme Feb 01 '18 at 09:16
Did you try Picasso? – Bertram Gilfoyle Feb 01 '18 at 09:27
Yes, it didn't help unfortunately. – Keselme Feb 01 '18 at 09:41

Solved my problem with this solution. The problem was that I was using RecycleView, that came from an injected fragment, inside of NestedScrollVoew. I guess they both contradict each other so that caused the slow scrolling.

recyclerViewsetNestedScrollingEnabled(false);

The above line makes recyclerview scrolling smoother in a NestedScrollView.
