hello everyone, I am just starting composing… is there a way to put a ripple effect on a

Surface

? I have tried:

Surface(modifier=Modifier.clickable(indication=….))

but

indication

is not resolved what is the correct way to do that?

Hey guys! Just started using compose in a live-graph implementation which uses an existing view that live updates from values being produced from Rx. Has anyone had issues with their app freezing due to updating views frequently within the main compose view? Code in thread

Hi! Does Compose have a simple or idiomatic way to create a button which calls an onPressed function every N milliseconds as long as it remains pressed?

Hi folks, I have noticed that the

Text

have some

padding top

by default. Anyone knows how to remove it?

Hey ! I was wondering - is there any reason for which `androidx.compose.ui.layout.ContentScale`is not a

fun interface

?

I’ve just submitted my “Newton’s Timer” for Week 2 of #AndroidDevChallenge ✌️ https://twitter.com/MaciejCiemiega/status/1369403866454896652

what is the equivalent of ValueAnimator on jetpack compose?

is

onGloballyPositioned

supposed to be called more than once after a layout? Or is supposed to only be called once it’s positioned? I ask because I have a composable that is constantly calling

onGloballyPositioned

despite not moving or recomposing (at least to my knowledge).

Hey all, I’m using the Material ListItem ‘trailing’ property, and trying to align my trailing content in a column.. with difficulty

Is it possible to make games in compose? Or is Unity more for that stuff?

Repost of an earlier question that didn't get much traction, but I want to make sure I'm not missing something. Does compose material give you a "toggle button group" composable like this out of the box like the legacy view system?

(RxJava3) If you're creating an observable to emit values and subscribing in your composable with

subscribeAsState()

, is there a way to unsubscribe from that? Code in thread

What would cause this exception? I’ve narrowed it down to an ExoPlayer view, but the problem is I don’t know why it’s doing it

My app sometimes crashes when I change code in the IDE. There's a large tombstone and some java stacktrace about trying to attach an agent, etc... A HotReloader is mentioned a few times. Is that something that can be disabled, because it's very annoying.

How can I make a

Row

wrap its content, but have a max width of half its parent?

Is it possible for a child composable to ignore the padding of the parent?

Does anyone knows how

item{}

works in LazyColumn? I’m having a weird issue with it If i have 2

item

block inside a LazyColumn when i scroll pass the all the elements in the first item block and scroll back to it, all the composable in the first item block got recomposed even if the data haven’t changed.

The width of the first element fluctuates when using fillParentMaxSize inside a LazyRow, is it a bug or am I doing something wrong?

Hi, I have some properties on my view model which my view subscribes to. One of these is created by “derivedStateOf”. I am trying to keep my view light so when this derived state changes i need to do a bunch of steps inside in a function in my view modell. Is there any way to subscribe to “derivedStateOf” inside a view model (ie outside of the composable) or do i need to instead make these properties a flow so i can subscribe to them both inside and outside of a composable? Thanks!

So i'm using a ModalBottomSheetLayout inside an LazyColumn. The Modalsheet comes up on the button click which is one of the item of the LazyColumn. And i'm getting this error

java.lang.IllegalStateException: Nesting scrollable in the same direction layouts like ScrollableContainer and LazyColumn is not allowed.

when working with

NavigationComponenet

and

BottomNavigation

I have a problem with tabs being selected (code in thread)

My indeterminate progress indicator keeps re-starting, looks it keeps switching to it's initial state after a second. How should I combat this?

CircularProgressIndicator()

I have a very naive algorithm to generate an hsv color palette by using a nested loop to walk through each pixel, calculate the correct color for it, and then draw it to a canvas (using Painter), and then creating an Image for it. The problem is that it doesn't scale well for sizes larger than a few hundred pixels. Is there a more performant API I can use in common compose, or would I have to delegate to the platforms (Android and desktop in this case)?

I’m trying to grasp how the lifecycle for the composables works comparing to the traditional lifecycle of activity or fragment. Let’s say that I have functionality that is fetching data from the backend every second while the screen is visible. For example, with activity/fragment I would start fetching data in onResume and I would stop it in onPause. How should I implement such functionality with Compose? When I’m using navigation components then viewmodel is still alive even when another screen is pushed above the one that should be stopped. Could somebody explain this to me? Thanks.

Hi Guys ! why my simple state handling isn't working ?

class Core {
    val texts:MutableList<String> = mutableListOf("Salam !","Hello World !")
    fun add (text:String):Core{
        texts.add(text)
        return this
    }
}
fun main() = Window {
    var core by remember { mutableStateOf(Core()) }
    MaterialTheme {
        Button(onClick = {
            core = core.add("salam ! salam !")
        }) {
            Column {
                core.texts.map {
                    Text (it)
                }
            } } } 
}

Hi, I'm trying to use rememberSaveable with Enum but it's not working, not sure what I'm doing wrong here.

So while clicking on any of the clickable component in Compose, i see that there is a grey color bar comes up for a sec, can we customise that effect, may be to a different color
