I have a horizontal recycler view inside of a vertical recycler view. Think of it as a slideshow inside a feed of content views. When the content view with the slideshow loads, it seems to load all 25 views rather than just the ones that are visible on screen. What I want to be able to do is set a limit on how many elements are loaded that are not currently visible. Is this possible with nested horizontal inside a vertical recyclerview?

Here what I tried:
I can able to achieve this layout using Wrapping Horizontal scroll view and recyclerview inside Nestedscroll view.
The problem is :
When I put recycler view inside any of the scrolling containers such as scroll view or Nested scroll view
Its loading all the items in recylerview at once which is not a implementation of recylerview,hence pagination is not achieved.
Requirement:
1.Top header cards should scroll horizontally which is of a (fixed) Limited size.
2.Label for the vertical scroll view
3.Recycler view for vertical scroll of items
All the above should scroll vertically.Please help, or suggest any better way doing this layouot.enter image description here
Yes you can achieve this by having parent layout as <nestedScrollView> and in child you can take 2 recycler view of which one of them should be horizontal and another should be vertical.
set property android:nestedScrollingEnabled:true and your are good to go.
In a app we have a activity which displays a list of textview let us take a list of numbers 1-9 or more than that.Which view is useful to display textviews either scroll view or Recycler view?
Recyclerview itself has scrollbar implemented in it. It is used when you have a large dataset.
ScrollView is used when you have a limited set of children on your UI and they are fitted out of your screen, so ScrollView is implemented here to scroll your layout to see all the children.
My question is why do wrap recycler view into nested scroll view
Does it relate to smooth scroll of recycler view
Actually i am creating app which fetch 2 images and the scroll of recycler view in that is very slow so should i wrap it into nested scroll view for smooth flow or compress images and store them
I am a bit confused on this topic ?
Wrapping Recycler view in scroll view is like a two sided blade. You should be careful about using it.
because when you use it, the recycler view will loose its advantage of recycling unneeded rows so at the same time you will have references to all those view, so if you have rows with many graphical item it will make problem for slow devices.
If you see putting the recycler view inside another nested scrollview solved your speed problem, It means you do a mess in the adapter of recycler view.
Do not do any heavy process in adapters and onBindViewHolder
Project contain the main layout with fragment included.
Included fragment contain recycle view inside the "nested scroll view",
I couldn't create multiple recycle view without using nested scroll view
So I am using nested scroll view to view multiple vertical scroll recycle views, but all images are loading at the beginning instead of loading one by one image loading.
i have a fragment which has a stationary Image View at the top , some linear layouts to display the texts and List View at the Bottom. i want the entire screen to go up(that stationary Image View and middle part) when i scroll down in the List View.
I tried to place all layouts in a single Linear Layout and put it inside Scroll View since it has only one direct child..but that makes only the List view scroll able.
Try using CoordinatorLayout and scrolling behaviour from the design library.You can find a great tutorial here
