Scroll behavior in nested RecyclerView with horizontal scroll

Question

I have to create vertical RecyclerView with nested horizontal RecyclerView in every item. Everything is within CoordinatorLayout. When I scroll by tapping outside nested RecyclerView toolbar hides, but when I scroll parent Recycler by tapping on nested one toolbar stays.

Any help would be appreciated.

Here is my xml layouts:

main_activity.xml:

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

<FrameLayout
    android:id="@+id/fragment_frame"
    ...
    android:fitsSystemWindows="true"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

<android.support.design.widget.AppBarLayout
    ...
    android:fitsSystemWindows="true"
    android:id="@+id/appbar_layout">

        <include layout="@layout/toolbar"/>

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

Here is toolbar.xml :

<android.support.v7.widget.Toolbar
    android:id="@+id/main_toolbar"
    ...
    android:fitsSystemWindows="true"
    app:layout_scrollFlags="scroll|enterAlways">

    <TextView .../>

</android.support.v7.widget.Toolbar>

fragment.xml:

<android.support.v7.widget.RecyclerView
    ...
    android:scrollbars="vertical"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

And recycler_view_item.xml:

<RelativeLayout ...>

    <TextView .../>

    <!-- fixme(CullyCross) fix bug with hiding toolbar -->
    <android.support.v7.widget.RecyclerView
        ...
        android:scrollbars="horizontal"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        />

</RelativeLayout>

Thanks,

Any luck? i am facing the same issue!! – Typify

@RafiqueMohammed nope, sorry – Peripteral

@AntonShkurenko did you get the solution.. I'm face the same issue.. – Rubberneck

@Rubberneck nope, I didn't, I left that job :) Try the solution below, it seems to be true (I didn't check), if it's true just upvote it – Peripteral

Answer 1

As requested here is the solution I found good enough so far:

In my case I have a nestedScrollView with 4 RecyclerViews set to scroll horizontally inside. For each of those RecyclerViews I have done this programatically:

restaurantsRecylerView.setHasFixedSize(true); 
restaurantsRecylerView.setNestedScrollingEnabled(false);

You probably don't want the fixedSize, not sure if it will make any difference, my list is always 25 so I can use that for performance. After having done this I can scroll without issues even when I touch on the recyclerViews

Hope it helps

setNestedScrollingEnabled helped in my case. Not that you can also set this in xml using android:nestedScrollingEnabled="false" :) – Campagna

I disabled the nested scrolling only and it also worked. Thanks. – Chinkiang

XML android:nestedScrollingEnabled="false" for nested recycler works using Groupie. – Latish

Answer 2

Try with RecyclerView inside android.support.v4.widget.NestedScrollView.

<android.support.v4.widget.NestedScrollView
        android:id="@+id/nScrollView"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

<!-- Set other views of your Layout -->

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

Also try with different layout_scrollFlags in Toolbar and

RecylerView.setNestedScrollingEnabled(false); // set it true or false as per requirement

I'm having the exact same issue. I have a list of horizontal recyclerViews all of them inside a NestedScrollView. If you scroll tapping on one of those recyclerViews the coordinator layout doesn't work properly. The toolbar is not hidden or shown, if you tap anywhere else is fine. Also there is a really bad experience when trying to scroll horizontally. – Colunga

@Lancelot I didn't find the answer that time, if you find it, write an answer here, I'll accept it – Peripteral

Hi @AntonShkurenko this is what I've done and I'm happy with the solution so far. In my case I have a nestedScrollView with 4 RecyclerViews set to scroll horizontally inside. For each of those RecyclerViews I have done this programatically: restaurantsRecylerView.setHasFixedSize(true); restaurantsRecylerView.setNestedScrollingEnabled(false); You probably don't want the fixedSize, not sure if it will make any difference, my list is always 25 so I can use that for performance. After having done this I can scroll without issues even when I touch on the recyclerViews – Colunga

@Lancelot hm. CoorinatorLayout handles scroll now? Toolbar hides/collapses? etc? – Peripteral

@AntonShkurenko Everything works as expected by making that changed. The problem is that those recyclerViews enter in conflict with the coordinator layout and the nestedScrollView. – Colunga

@Lancelot I was struggling with this and your solution is what I was looking for. I struggled to find this answer, if you put it as an answer rather than a comment it will probably be easier for other people to find and you will get some rep. At least from me. Thanks. – Viburnum

Hi @DanielJulio I've just posted as an answer, I'm still trying to make it better as the horizontal scrolling is a bit difficult some times. Thanks for your comment. – Colunga

Answer 3

We can achieve this in XML

android:nestedScrollingEnabled="false"
