Incase this ends up helping someone... We were animating visibility of a collapsible section in our lazy list by setting the "invisible" items to 0px height and this was causing a lot of latency.

If it's collapsible, why animate its measurement manually? Just use the AnimatedVisibility(Boolean) block around your composable, or take a look at the Animations docs to see how to handle performance, if it is the built in function really isn't suitable for your use case. My guess is you're skipping steps that makes it performant, and AnimatedVisibility would handle it. Just keep in mind that each an every step of the animation (every pixel you reduce by) triggers a recomposition of the specific composable, and every single change to the specific composable triggers a recomposition of the Lazy list. Also don't measure performance in a non release build (if you are). I've been collapsing cards in lists since Compose was beta, and I've never experience any jank, so just revise those manual implementations.

Greet! but there's no documentation to how to implement custom LazyLayout
@andreykulikov18442 жыл бұрын
Yes, we in fact intentionally didn't show it as the api is in its early stages and can change a lot. We didn't want this video to became outdated because of that. LazyLayout is not yet production ready, but I hope that the public documentation and the ability to read the sources of our components will allow the early adopters to try it out

HOW DO I UPDATE THE LIST WHEN I ADD/REMOVE ITEMS
@FrankOtten3 ай бұрын
You must make sure your items are passed through as state. When one of the children gets removed or added after the initial load you bubble it up back to the parent by using lambda's as parameters for the add/remove actions. Once something within the state changes it will automatically re-compose for you (and only the items which have changed).

Great video. Thanks! I tried adding a custom Arrangement.Vertical to my app and that part shown on the video by Andrey worked well but then tried adding spacing to it like what Arrangement.spacedBy does and failed. Are there any examples of a custom arrangement with item spacing?
@andreykulikov91662 жыл бұрын
When you implement your own Arrangement.Vertical you can also override spacing property, it is defined on the same interface

@@andreykulikov9166 i have overriden the spacing property but still havent got the spacing applied. I was thinking I would need to factor the spacing in the calculations for outPositions?
@andreykulikov91662 жыл бұрын
@@adrian110288 yeah, you need to provide your spacing for the spacing property, this will be used when you have enough items to fill the whole viewport, and then also take into the account the spacing manually when you do the outPositions calculations for the case when you have less items than needed to fill the viewport

Yet Compose saves loads of time. I am reading through the entire docs section from the android developer website and it makes things very clear and easy. First I was like wtf is up with those remember items and stuff, then later I realized for like nearly all composables they made separate remember functions so you can easily re-use them in your composables for both re-usability and easy programming. I am still fairly new to programming but seeing how Compose works makes me quite enthusiastic!
