Anybody tried LazyColumn or LazyGrid on Android TV? For me, they don't scroll down. See the attached video, first example is with

LazyColumn

, second one is just

Column

with

verticalScroll

modifier. Edit: Looks like this is related to d-pad navigation because when I swipe using

scrcpy

, all the rows are there.

Do you think it’s a bug with your code or bug with compose in general? What did any official forums say about it?

I think it's a bug with Compose given that swiping works fine and because there's been issues with d-pad navigation in compose in the past but I'm open to suggestions. The roadmap says d-pad navigation is in-focus so I'm guessing this would be the right time to bring up any bugs with it.

Bet they’d appreciate your video and a report of what is happening! 🤔

In the past, I've posted here and verified a behaviour before submitting an issue.

There is a known issue on lazy lists not scrolling at the moment

@Jon Boekenoogen is it for Android TV only or for Phones too?

Lazy list scrolling with dpad in general (tv, chrome os, phones)

We’ve solved this by using

rememberLazyListState

and

scrollBy(px)

to center the items upon focus (

scrollToIndex()

also should work). We’re on version 1.0.5. We experienced the same issue as you, and it seems it’s related to the items not being visible.

@Tarjeison Did that completely solve the problem? I tried

scrollBy

and

scrollToIndex

, I think

scrollBy

worked but

animateScrollBy

didn’t. Would it be possible for you to share that part of the code by any chance?

I think this is an issue which occurred in version 1.1.0 and might be the same same as this issue: https://issuetracker.google.com/issues/212982472 I’ve also added a gist in the issue. My team decided to wait for a built in focus navigation support for compose before implementing it on AndroidTV. https://issuetracker.google.com/issues/184670295

Ah, that makes a lot of sense because I only tried it with 1.1.0. I see that Ralston Da Silva is actively working on it in this CL: https://android-review.googlesource.com/c/platform/frameworks/support/+/1967229. Looks like a while before it’s all done though. I tried it locally a few patch sets ago 🙂
