How to display a large 2D dataset on Android ?

Question

Hello 🙂

I have a 2D dataset (r rows and c columns).
I already have used a "recyclerView" before, using a grid layout manager.
However, it seems that when we set a column count too large (let's say 200 columns), the app is lagging, even if the visible part is only 6 by 6 tiles.
So, I programmed something less "user-friendly" which consists of buttons to move around in a grid view.

Is there a way to make the recyclerView as fast (or close) as a classic use, or a totally different way to display this ?

(I want the user to be able to navigate without any buttons)

Thanks in advance, have a great day ! 😊

Answer 1

Are you using Jetpack Compose or XML? If you're using Jetpack Compose, you can try using Lazy Column.

Lazy Column is the replacement of RecyclerView. I am not sure if it's in XML though, I'm afraid. I generally only like working with JC.

Oh I am not working with Jetpack Compose for the moment... But I'll check this
