compose-samples VS header-decor

The official documentation provides a comprehensive guide on the basics of Jetpack Compose, components, layouts, theming, and more advanced topics.

Apparently Jetpack Compose is an Android copy of SwiftUI?

Only two HN threads with comments: https://hn.algolia.com/?q=jetpack+compose

If you want to take a look at code, we have the Jetnews sample app that support different screen sizes. And Jetcaster also implements features such as table top mode.

check this out : https://github.com/android/compose-samples/tree/main/Crane

So I would say that instead if learning everything from Android SDK, you should just set a goal to create some app. Learn about Activities, their lifecycle, layouts (or Compose if you want to be more up to date). Try to implement your app based on this. Then improve your app using Fragments and their lifecycle. If you truly want to understand Views, which are essentially the building blocks of Android UI then I would recommend implementing your own custom View, which will have completely custom look - it is cool thing to try and you will learn how it all works inside.

The compose samples by Google are a good reference to look into: https://github.com/android/compose-samples

Basic understanding of Jetpack Compose.

The compose-samples repo has a comprehensive list of samples ranging from low to complex projects which might be worth a look.

For instance, there is a link to this repository, that contains all sorts of samples, that are up to date and ready to use. That's cutting edge, which is a recommended start.

https://github.com/ebarrenechea/header-decor this lib worked wonders for me back in the day

RecyclerView is easy. I'm sure you can't do a two-level sticky header with Compose that easily, and SubcomposeLayout truly is not easier than, well, anything really.

We had to use it for our design spec using https://github.com/ebarrenechea/header-decor because it was split up by date and by location within the list iirc but it looked pretty cool actually

Then you have "advanced concepts" that you actually need in your everyday life like subcomposition. No one so far has been able to answer "how to make a two-level sticky header virtual list with lazy loading using Jetpack Compose", and unless someone knows the answer, nobody actually truly understands Jetpack Compose.

How do I make a 2-level sticky header in Jetpack Compose please guide me

I used to use https://github.com/ebarrenechea/header-decor it's a shame it's deprecated but the idea should still work (item decorations)

We were using this https://github.com/ebarrenechea/header-decor
