I am using systemuicontroller for changing navigation bar and status bar colors. I succeed but as you see in screenshot I cannot change the color icons even by putting true or false for the darkIcons parameter. What I’m doing wrong?

Hey guys, Is there some way to draw only behind the status bar and not behind the navigation bar while going edge-to-edge? Right now I am using a workaround by adding a

navigationBarsPadding

modifier for my entire app content. But is there any other way?

Hi, is it possible for

LazyRow

items (with content image / title / max 3 lines) to fill to the height of the

LazyRow

?

fillParentMaxHeight

doesn’t seem to work

I'm probably missing the reason the compiler is angry about using the

composed

modifier here.

@SuppressLint("UnnecessaryComposedModifier")
@Stable
fun Modifier.clickableNoIndication(onClick: () -> Unit): Modifier = composed {
    clickable(onClick = onClick, indication = null, interactionSource = remember { MutableInteractionSource() })
}

I have to add the suppression otherwise it complains. But if I don't use it, I can't use remember. Am I missing something simple?

Hello everyone, i'm facing a problem with LazyVerticalGrids that causes my app to crash. I'm using a LazyGrid to display a list of photos (receiving the image url from an api and loading in my view using Glide) that can be cleared whenever the user sends a request with a differente filter, but when the list is cleared my application crashes with an Index out Of Bounds Exception

this might be a really obvious and common recomposition issue, but can anyone point me in the right direction with this? • large list of data being loaded by LazyColumn (fills max height of screen) • when scrolling down, scroll is smooth and fast with no issues • when scrolling up, if any of the items in LazyColumn are taller than the screen itself, the scroll looks like it jitters and kind of gets “stuck” when it tries to scroll past those items • this jittering does not occur scrolling past smaller items, in that case going up is just as smooth as going down.. it’s only with taller items it feels like maybe recomposition is occurring, but I don’t quite understand it. any tips? does this sound familiar to someone?

Hello everyone, I'm having an issue with an

OutlinedTextField

if I try to use it for number input only and restrict it to 2 digits after the decimal separator, see code in thread

Is there an established convention for handling different status bar colors for different screens? Currently I’m changing the colors with the Accompanist

System UI Controller

on the root of every screen

I want to change black color to red but when I set tint also purple element goes to red. Is it possible to change only black elements? That image is vector .xml

Image(
    painter = painterResource(id = R.drawable.wifi),
    contentDescription = "",
    colorFilter = ColorFilter.tint(Color.Red)
)

How do we test resources with Compose UI Testing? I have a valid context with:

InstrumentationRegistry.getInstrumentation().targetContext

Then calling the resulting

context

with

getString(R.string.app_name)

returns: Using

Method threw 'android.content.res.Resources$NotFoundException' exception.

It does this in my project along with the default compose template project in Android Studio. It would be handy if we had resources to test since we can then test multiple languages with UI tests and produce screenshots for this to send to our QA team as part of a release build. One project is using the latest alpha version, and the other is using the latest stable version.

Im getting errors while loading images on some devices.

java.lang.RuntimeException: Canvas: trying to draw too large(105294960bytes) bitmap.

is there a way to fix this? I also tried accomponist

Hello, I'm using the deep link trick to navigate to a composable from a notification, and there's an issue I'm having that I didn't have when I was using separate activities and pendingintents without deeplinks: The state of the previous destination is always lost on navigating from the link, the entire activity being destroyed, even after navigating multiple times from the very same deep link uri. I'd like to not have that useless recreation and state loss happen when the deep link points to the destination already on top. Is that possible at the moment, or shall I file a feature request? Note that I specified

android:launchMode="singleTop"

in the

AndroidManifest.xml

for the host Activity.

Would it be a bad idea to use

animateXYZAsState

in a composable thats used literary everywhere? Use-case: Its a Text composable, and Id like to animate changes to its state (dim, highlight, etc).

Hey, I have

HorizontalPager

with

x many

items (can be 1 can be 20+) and each one of the item needs to call a BackEnd to fill it's information. So every time i receive a pageIndex i call

viewmodel.getMeSomeCake(index)

and when i receive it i want to fill the screen. I want to use StateFlow but i got the same problem as if it's a fragment with ViewPager. Pager creates the

n-1

,

n

,

n+1

pages so the data i got is not the one for the visible page. is there any recommended ways to do it on compose?

Can we already use Material You with Compose?

If im using

Canvas

composable i have access to its size inside

DrawScope

. I want to use this size to create

Path

and then clip it out. However, i shouldn’t allocate Path object there, right? So i want to use

remember

, but i can’t in

DrawScope

. Am i missing something, or the only way to do this is to measure constraints outside of Canvas, create Path with remember, and then use it inside DrawScope?

So I want to use mutableStateOf in my ViewModel like this:

private var _state: State by mutableStateOf(Loading)
    override val state: State = _state

    fun onLoadClicked() {
        _state = Loading
        viewModelScope.launch {
            _state = when (val content: Content? = loadData()) {
                null -> Error
                else -> PresentData(content)
            }
        }
    }

So now I would like to test the behaviour of onLoadClicked. But I do not know how to verify that calling that function sets the state to Loading and than to PresentData/Error. I could observe a liveData and remember all states is was set to but how do I do it with mutableStateOf?

So, i’m looking to put some logging into a NavHostController. I started with a state object that has an empty route string, and then a destination listener that updated the state object’s route string. The problem then is that i want to listen to the state object and do some logging as it changes. I tried a SideEffect, but for whatever reason, it’s only getting called a single time with the initial version of the state. When i create the nav graph i would have assumed that it would update the state (which it does), but it never triggers the side effect for that first update (subsequent updates work fine).

I'm confused by this exception

java.lang.IllegalStateException: Nesting scrollable in the same direction layouts like LazyColumn and Column(Modifier.verticalScroll()) is not allowed.

when the compose docs clearly state

Automatic nested scrolling: Simple nested scrolling requires no action on your part. Gestures that initiate a scrolling action are propagated from children to parents automatically, such that when the child can't scroll any further, the gesture is handled by its parent element

The docs then go on to give a sample of nesting one vertical scrolling box inside another vertically scrolling box.

Is it normal that

NestedScrollConnection

is not called at all when `listState.scrollToItem`is called manually?

Animation: What is

FloatTweenSpec

? and how is it different from

tween

? 🤔

I have a

LazyColumn

with

AndroidView

items and I’m just noticing that

AndroidView#update

is getting called on every scroll/recomposition. Is this expected?

Is it possible to call a parent's onClick method or Clickable modifier inside of a ClickableText's onClick method? I want clicks to bubble up if the user did not press a link.

I have a compose Button onClick handler that saves important information. It's too slow to just run it on the main thread. GlobalScope.launch{} pops out a warning about that API being delicate. I don't want the coroutine to be suspended and cancelled if the view is dismissed, so LaunchedEffect seems to be the wrong approach. Where is the appropriate place to situate the coroutine scope?

but i don’t see

animateBoundsAsState

? 🤔 removed or its doc mistake?

I have random rare crash that makes no sense at all that seems to be generated from

Modifier.weight(1f, fill = false)

Error:

Is there something I miss in the stack trace?

have started to play around with MotionLayout but getting a lot of jank when using it with LazyColumn so wondering whether what I'm doing wrong. Basically I'm creating a collapsible style header style, but have simplified the code down for the purposes here, so I have a box to represent the header with the rest of the screen taken up as a LazyColumn. With only a handful of items (simply

Text

) in the list the animation becomes jerky. In comparison, having only the button in the list the animation is relatively smooth. (Videos attached) (Code and videos in thread)

When I set

isError = true

to the TextField the border's color not becomes only Red but I see it's combination of PrimaryColor and Red, any tips about the issue?

Are there plans to make a Jetpack Compose date/time picker? (You can use Android's views but these change from os version to os version etc. And the material library's date time picker uses fragments which is annoying)
