I have a MotionLayout which basically contains an image and a ViewPager. The ViewPager renders a fragment with a RecyclerView in it.
At first the image has normal size, when i drag up, the image reduces its size and the ViewPager (with the RecyclerView within it) expands.
The problem is that the MotionLayout keeps intercepting the scroll action, so if the RecyclerView is expanded, and the user scrolls down, the MotionLayout will expand the image, rather than letting the RecyclerView scroll.
What i would expect is that the MotionLayout will expand the top image only if the RecyclerView has reached the first element, in that case since the RecyclerView cannot scroll anymore, the scroll action would be managed by the MotionLayout.
I am aware that within MotionLayout I can set the attribute moveWhenScrollAtTop="true" to get that behaviour, but that only works if there is just a RecyclerView, but not if the RecyclerView is within a ViewPager.
Has anyone faced this issue?
if your xml file contains nested scrollview just add android:nestedScrollingEnabled="false"

I have a Recyclerview with a Cardview and inside there is another Recyclerview like Netflix. So I cann scroll vertical and horizontal. Insider the inner recyclerview there are some cardviews with buttons. My Problem is if I scroll down and up again, then there apears some Space inside the Carview.
How does this happen?
Start
After Scrolling
Any suggestion or idea is helpful.
Note: Without the Itemdecoration (Page Indikator) it works and no Space appears.
How to properly scroll to a position in nestedscrollview which is inside a coordinate layout? When I use scrollTo(), it seems like the view inside AppBarLayout is loosing the ability to scroll down when I scroll to the end of NestedScrollView and coming back to top. What I need to know is how to programtically scroll to a position in nestedscrollview without causing problem with the normal behavior of collapsing layout.
Issue is similar to what is mentioned in this post:
The Coordinator layout doesn't Scroll up for a specific position
There is a Gif attached along with the above question:

I have tried the solution in above link, but it is not working.
My layout is ConstraintLayout and hierarchy is like this:
There is top view area that takes half of the screen, below that a TabLayout and ViewPager. In this ViewPager there are 3 tabs which contain a RecyclerView. When any RecyclerView is scrolled, top area collapses to 10% of height and ViewPager expands. Due to this RecyclerView expands too. However, after this expansion, RecyclerView items stars overlapping too.
What could be the cause of this?
If you use the ConstraintLayout and enable animation for each item when has changed. Let disable that issue will be resolved.
android:animateLayoutChanges="false"
My activity contains an AppBarLayout provided by the design library 23.0.1, it hides when I scroll up. I have a RecyclerView with each child item containing a RecyclerView too, basically a nested RecyclerView going on.
My issue is that when I touch on any of the inner RecyclerView's child and scroll up, the AppBar does not hide. However, if I place my finger somewhere else (not on the inner RecyclerView) and scroll, the app bar scrolls up just fine. Why is this happening? I even tried adding the appbar behavior for the inner recycler view, yet the app bar would only scroll up when I touch somewhere else and scroll.
Note: the inner recyclerview has a fixed set of items that would be visible at all times, basically, there is no scrolling within the recyclerview.
There is a similar question and a provided solution would be to intercept the touch of the inner recyclerview and pass it to the parent recycler view. But this disables the click events of the children in the inner recycler view, I do not want that.
You need to set the nested scrolling flag to false for inner recycler views.
mSomeInnerRecyclerView.setNestedScrollingEnabled(false);
I have a situation where I have a Recyclerview which slides horizontally inside a ScrollView. Now the situation is when I do a horizontal swipe on the Recyclerview, instead of scrolling the cardviews inside Recyclerview, it scrolls the screen up, which disturbs the user experience.
Any solution or approach to avoid vertical scrolling when the person is doing a horizontal swipe on Recyclerview?
The solution is actually quite simple.
put the horizontal RecycleView as an item in a RecycleView, instead of using a scrollview.
then when you scroll it behaves as you want it to.
Thats what I did and it works perfectly
