?

How do I troubleshoot why Preview annotation isn't working in my project? It does work on very simple UIs, where I show a text box, for example, that is hard-coded. I am using Kotlin 1.6.10 on compose 1.2.0-alpha07

Hello everyone! I want to implement floating search bar like on google app (video in thread) with lazylist underneath. I’ve tried to react on list scroll and it’s working almost as I need: search hides but then shows on every new list item

Hello, I have a page with a custom

TopBar

mimic(it is not a Scaffold

TopBar

, rather just a

Box

due to transparency) and I need to use a sticky header in my

LazyColumn

but the header doesn’t stick to custom

Box(TopBar mimic)

as it probably doesn’t treat it as a

TopBar

. How do I manage to have a sticky header with a custom mimic?

Is there a better way of doing this animation?

🤔 Subjective question: What is the size (LOC) of

@Composable

function when you ask yourself "should I divide this into separate composables/files"? 1️⃣ 50 lines 2️⃣ 100 lines 3️⃣ 200 lines 4️⃣ 300 lines 5️⃣ It's not dependant on number of lines but rather number and cohesion of parameters 6️⃣ It's fine as long it does "one thing". 7️⃣ Other 👉 comment

When will rememberSaveable's data actually be cleared?

Is it possible to determine if a modifier is used such as clickable? Or is it possible to clear the clickable modifier? Or is it possible to ensure a modifier passed as a param is only able to have a subset of modifiers?

Are there plans to open

androidx.compose.foundation.lazy.layout.LazyLayout

, or even better smaller parts like

LazyLayoutItemContentFactory

and

LazyLayoutPrefetcher

? They would help so much for creating custom lazy layouts.

In

LazyColumn

, I'm using fading animation for item animation. When item is added, all the items on the screen animate. How to get only that item animated and rest of the items shift the positions? Details in the 🧵

My business layer doesn't include Compose, but I'd like a method in it to suspend while waiting for the user to respond to a dialog. Showing the dialog uses

@Composable

, which doesn't exist in the business layer. Any patterns on how to structure that? I'll put what I have so far in the thread.

How can I nest LazyColumn inside LazyColumn? The page as a whole is a LazyColumn, but its subcards also need to be a list

Any way to keep it vertically centered when the field has focus?

Does this answer still hold true? "What's the purpose of paddingvalues in a scaffold?" https://stackoverflow.com/a/70210638

Hi, how can I set a Column element to have a maximum width as a fraction ? (like

fillMaxWidth()

but I only want to limit the maximum size)

Can I get hold of the “Window” object from a composable function, or do I have to send that in as a parameter?

im sure this has been asked before, but at my company with a rather large app, migration will take time to Compose. We currently have a few screens that make use of shared element transitions. is there any support for shared element transitions between traditional UI and Compose?

Can someone advise on using

MultiplePermissionsState

as the

key

in a LaunchedEffect?

If using AGP 7.1+, will compose’s baseline profiles automatically be bundled with APKs/App Bundles, or does the app module need to declare a dependency on

androidx.profileinstaller:profileinstaller:1.2.0-alpha01

? According to the docs, it seems like that dependency is only necessary when creating custom profiles, but just double-checking 🙏🏼

I want a composable to have a max height of 80%. Is there a way to do that other than this?

BoxWithConstrain {
   val maxHeight = maxHeight
   Box(
     Modifier.heightIn(min = 0.dp, max = maxHeight * .8f)
   )
}

I want to slowly migrate to Jetpack Compose view by view and I have a horizontal

RecyclerView

in my

NavigationView

. When I use the

LazyRow

or

Row(Modifier.horizontalScroll())

the touch events are not intercepted properly and instead of scrolling the row, the

NavigationView

is closing. Is there any way to make the

ComposeView

intercept touch events?

I also want to migrate to Jetpack Compose, I created a component that is fixed at the bottom of screen and it has a section that expands on click. When I used it in a compose activity, it worked fine, but when I used the same component in a old activity using

ComposeView

inside a

ConstraintLayout

it began flickering when it is expanding or contracting. Anyone can help me? I created a minimal example of it happening here (video on README.md)

Hi, how can i get LazyColumn scroll percentage ?

private fun <T : Any> SavedStateHandle.saveableMutableStateOf(
    key: String,
    saver: Saver<T, out Any> = autoSaver(),
    init: () -> T,
): MutableState<T> {
    @Suppress("UNCHECKED_CAST")
    (saver as Saver<T, Any>)
    val value = mutableStateOf(restoreOrInit(key, saver, init))
    saveToStateHandle(key, saver, value)
    return value
}

private fun <T : Any> SavedStateHandle.restoreOrInit(
    key: String,
    saver: Saver<T, Any>,
    init: () -> T,
): T = run {
    val restored = get<Bundle>(key)?.get("value")?.let(saver::restore)
    restored ?: init()
}

private fun <T : Any> SavedStateHandle.saveToStateHandle(
    key: String,
    saver: Saver<T, Any>,
    value: MutableState<T>,
) = setSavedStateProvider(key) {
    val saverScope = SaverScope { true }
    with(saver) {
        bundleOf("value" to saverScope.save(value.value))
    }
}

...
//usage
private var _state by savedStateHandle.saveableMutableStateOf(STATE) { initialState }

this used to work but now in

1.2.0-alpha07

setting

_state

doesn’t save value to

SavedStateHandle

I have a

data class

, and i created a mutableStateOf<MyClass>(). What is the best way to update this data class with mutable state on ViewModel? • Set value directly:

myClass.property = "value"

• Or use copy function:

myClass.copy(property = "value")

New compose generate crash

java.lang.IllegalArgumentException: Inconsistency between the count of nodes tracked by the state (0) and the children count on the SubcomposeLayout (3). Are you trying to use the state of the disposed SubcomposeLayout?

with LazyList. Anyone can explain more the error so I can build a repro before opening an issue ?
