是否可以在垂直 recyclerview 中有一个水平 recyclerview？

Question

The main recyclerview which is vertical recyclerview shows all the deals in the layout

But what I want to achieve is:

• after the first 10 deals, I want to display a (horizontal recyclerview) of 5 recommended deal
• after the next 10 deals, I want to display a (horizontal recyclerview) of 5 recommended deal
• after the next 10 deals, I want to display a (horizontal recyclerview) of 5 recommended deal and so on…

I have attached the image of how i want the design to look.

I have no clue on how to implement this. But I have both the recyclerview working separately. Just not sure how to combine them. I'm not even sure to code in the adapters or the main activity. I have attached the image of the horizontal recyclerview adapter and vertical recyclerview adapter. Please help me by showing me how to implement this feature. Thanks

Answer 1

For that purpose you can use NestedScrollView. NestedScrollView as the name suggests is used when there is a need for a scrolling view inside another scrolling view.

you can set like this:

android:nestedScrollingEnabled="true" 

According to your requirement.

Answer 2

I can't picture what exactly you want to achieve, but if you want to have vertical recyclerview which contains horizontal recyclerview, than you need to add adapter into adapter.

Item view that you use for vertical recyclerview should also contain recyclerview.

This should be good reference on how to achieve it.
