Hello!

hello, Joshua!

how can I help you today?

Hey, thanks for hosting this!

thanks for subscribing! :-)

So I had a question about dealing with dynamic views in a recyclerview item

I'll give you an example design

So i have this currently implemented, however its not very performant

Each of those cards are recyclerview items and inside I can have any number of rows

unless there are going to be a lot more cards, you won't actually recycle much, if anything

Yea, there wouldn't be too many generally, but even with this few.

When i scroll it lags pretty badly

I tried keeping a viewPool so I don't inflate views each time I bind

it improved a bit, but its still pretty slow

RecyclerView already does that

How would you go about designing this?

what is the maximum likely number of cards, and what is the maximum likely number of rows per card?

Number of rows could be anything honestly, same with the cards

Someone could decide to have a exercise with 100 sets (not likely but who knows)

which would mean 100 rows in one card

and you're sure that you want this all on one screen? that design seems to be aimed for a tablet

I've looked at other designs (particularly fitness apps)

This seems to be what I would want to go with

but regardless the main issue with the performance is adding those rows into the view dynamically while binding

its definitely slow

Remember the card itself is the recyclerview item, the views inside are added as the recyclerview binds the card itself

yeah, I'm not sure that I'd go about it that way

I mean, you can do it, but I would lean towards a flatter implementation, where each horizontal thing is a row in the RecyclerView, with a variety of row types

I was thinking about that

However I would like to keep the card design

you still can

Maybe I'd implement a background in each item?

right

so it looks like its a whole card

Hmm

good idea

I think I'll try that Mark!

if I am understanding what's in the RV correctly, I think you wind up with three row types:

no, sorry, four: one for the short title, one for the table heading, one for an interior row, and one for an end row

Yea

alternatively, you could consider all rows to be "interior" and have the bottom of the card be another row

Yea that sounds right

okay that sounds awesome to me

AFAIK, if you do not set up any item decorations, each RV element should be immediately adjacent to the next one

so, the cards should be seamless

Awesome.

I'll try that out Mark! Thanks for the help

you're welcome!

if you think of it, let me know how it turns out!

I'll come back in a future session for an update!

Sure!

thanks!
