How to correctly implement a repeating nested nested layout in a list?

Question

Android

Available for Layout:
- sub_lay1 c 24 TextView c onClick (only half is used in run);
- sub_lay2 as ExpandableLay with 48 TextView (to display amounts if necessary).
Fill item_main_lay:
- 2 pcs. sub_lay1;
- 2 pcs. sub_lay2.
In activity_main in HorizontalScrollView we insert 10 pcs. item_main_lay.
This is my special case. For clarity.
And in general terms, the question sounds like this - how to correctly implement lists with
layouts stuffed with a large number of Views?

Answer 1

RecyclerView + AdapterDelegates.
I assume that most views are the same, and therefore will be reused.
Even if they are all different (which I will be surprised), they will still be created lazily as needed.
In particularly difficult cases, you will have to write your own LayoutManager for this.
