I tried out vector drawables a few months ago with Compose. The loading of the vector drawables was async, which created issues for me with pop-in after the page was being displayed. Is there a way around that?

For supporting dark theme, the documentation says I have to use

private val DarkColors = darkColors(
    primary = Yellow200,
    secondary = Blue200,
    // ...
)
private val LightColors = lightColors(
    primary = Yellow500,
    primaryVariant = Yellow400,
    secondary = Blue700,
    // ...
)

but these can hold like 10 variables, I need my own custom color variables which change depending on the theme. Its super easy to do using XML resources but I am unsure if that's what I should do. Should I just use xml resources for this? or is there a way to handle those in Compose?

Is there anything similar to animateLayoutChanges on Compose? I am trying to toggle the visibility of a layout using AnimatedVisibility but the final animation does not run as smoothly as animateLayoutChanges would but just toggling the visibility of a View. Also my Spacer fully disappears when its placed in an AnimatedVisibility which I am not sure why

Do navigation routes have a length limit? seeing some weird behaviour where if my route is over a certain length (i.e.

workouts/{id}/edit

) it navigates to the next shortest route instead (

workouts/{id}

)

Hi All, After updating to beta04 for compose. I'm seeing a lots of unresolved references regarding the Kotlin based ArrayList that i was using

Please help. Didn’t find way to make it. I need shadow with offset and alpha 0.08 but elevation don’t allow it. See attached

In beta04 the keyboard navigation indeed works out of the box, but I find that if modifiers are in order

Modifier.focusModifier().onFocusChanged { ... }

, the

onFocusChanged

handler is not called, while if they're reversed

Modifier.onFocusChanged { ... }.focusModifier()

, it is called.

Where can i find documentation / samples on compose for the web and desktop? What i found for the web wasn't what i expected coming from Android. Instead of using

Box

,

Row

,

Column

, it used functions like

h1

which are closer to html.

Hi all, not sure if this is the right channel. Given the following minimal code (not sure this is Android / Compose specific),

class MainActivity : ComponentActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        setContent {
            var clicksAmount by remember { mutableStateOf(0) }

            fun onItemClick(index: Int): () -> Unit = { repeat(index) { clicksAmount++ } }

            BasicText(text = "Clicks: $clicksAmount")
            LazyRow(
                contentPadding = PaddingValues(12.dp),
                content = { items(listOf(1, 2, 3)) { Example(it, onItemClick(it)) } }
            )
        }
    }
}

@Composable
fun Example(index: Int, onClick: () -> Unit) {
    Column(
        horizontalAlignment = Alignment.CenterHorizontally,
        modifier = Modifier.padding(top = 12.dp).clickable { onClick() }
    ) {
        Image(painterResource(android.R.drawable.star_on), contentDescription = null)
        BasicText(text = index.toString())
    }
}

I get a huge build error when trying to build it. By the way, the combination of

by

(

var clicksAmount by

) and

++

(

clicksAmount++

) is the cause. For instance,

var clicksAmount = remember { ... }

or

clicksAmount += 1

builds just fine. Is this an issue? I tried to google but didn't find anything, probably missed the right keywords

Is it possible to run Compose with older Android Gradle Plugin versions? Looks like 7.0.+ versions causes

./gradlew check

to fail with weird lint errors we never had before.

Hello! Is it possible to have 'ThreadLocal' anolog for compossibles? I need to put parameter of the composable function to such structure to be able to take it from subcomposables without passing it as parameter. Globals can't solve this, cause it is possible to call such function with different parameter values and each should hold it's own 'ThreadLocal' value.

If I have a suspend function with some important long running code, and want to trigger it from a composable function, what is the standard way to start this long running function so that it is not cancelled when the component recomposes? Not clear on how to use the effect stuff for this

Is there any way to force all items in a Row to show? For example, if I have a row with text and a checkbox, then it looks good, but if the text is really long, it pushes the checkbox out of the row.

is there a way write a composable screen which support keyboard awareness, which mean when keyboard show or hide, it will re-compose.

I am trying to use

val parentViewModel = hiltNavGraphViewModel<ParentViewModel>("Parent")

but no matter what I do it imports the wrong hiltNavGraphViewModel which takes backStackEntry as a param and does not work in the end. When I type hiltNavGraphViewModel I can see the option for the one that has a String param but even after I select it and Android Studio auto completes the code to

hiltNavGraphViewModel(route = )

it is still the one that requires backStackEntry and route is red

Is LocalSoftwareKeyboardController.current Supposed to return a new instance every time it's called? Cause currently it does return a new instance every single time I call it

Is there any way to achieve

Reorder LazyColumn

items with

drag & drop

?

Is it possible for a Composable to have its size modifier recomposed, but say a gesture modifier on the same Composable not?

How can I vertically center a composable in a Row? If I use fillMaxHeight it will fill the whole screen. I cannot find a way to make it just fill the parent height.

Hi compose geeks. I am struggling a bit with state management, bottomNavigationBar and the map 😛 . I am using the approach from

AdvancedNavigationSample

, so every Tab has its own navGraph. I got three main screens: Map, List and settings(which is also the list TBH). The screens with lists works fine, the scroll position is maintained, nested fragments are maintained, etc. The Map view is recreated each time. Not all the components, but the map, which is added in

AndroidView

composable is recreated. I am saving the last location as a state, so the map shown the exact same place when I am coming back to it, but it always “calculates” or draw tiles again. Is that something for map specific that cannot be changed or something might be wrong with my

AndroidView

implementation?

It is recommended to only use Compose navigation? or should we use fragments etc instead? It doesnt look like Compose navigation supports animations yet.

Can I somehow disable the clipping behavior for scrollable lists? I'm trying to build a drag & drop and want to be able to move items (horizontally) out of the list, but they're clipped at the list bounds when using offsets.

I’m thinking about an alternative way to augment component appearance in response to

interactionSource

.

Indication

only allows to draw something, but not change how component renders itself, e.g. pseudo-3d button actually moving slightly when pressed, or a component shaking a bit if attempted to interact with it, doing component-specific hover effects, etc. I wonder if anyone already gave it a thought and have ideas/approaches on how to design it?

Do we have something for when we want to use one value for Preview and another one for Build?

is there a way to add a header(like a

Text

) to the a

LazyVerticalGrid

?

Is there a suggested way to create a preview if I use a ViewModel? Create a preview with mocked data? I just saw the IDE said it didn't support for viewmodels, so I was curious what the best practice will be

Is it better to use LiveData in a ViewModel or use

by remember { mutableStateOf(X) }

Using remember takes less time but I am not sure if its recommended over livedata? Although I am not sure if it matters in the end of the day at all or not

So I released a compose app for beta testing a few days ago and one of the testers experienced crashes while casually browsing the app. However, I don't see any crashes on crashlytics or ANRs on play console. Could this be related to compose?

Possibly related: it seems as though the compose compiler plugin is somehow deleting

init

blocks my plugin adds. Things work fine without the compose plugin, but adding it causes the my init blocks to not be present in bytecode (despite them showing up when dumping the IrClass from my plugin). Any idea how to debug this?
