Hello guys, may I ask why AnimatedVisibility still has ExperimentasApi annotation on 1.1.1 version ?

Hello everyone! Has anyone had trouble with navigation with a Xiaomi phone? I have a MIUI 13 that doesn’t complete the start navigation flow until you touch the screen

What is the appropriate way to implement show/hide

FloatingActionButton

when scrolling in compose?

Idea: 1-to-1 mapping from Compose to SwiftUI making Compose a cross-platform UI framework with KMM (no UI duplication).

Is there any way we can attach Bottom Sheet to Window directly without adding it in any Compose Activity inside Scaffold and invoking it. It should work like when it is needed just attach to window and display it on any composable. Any Idea ???

Hello, is there any UI Component visualization toolkit for jetpack compose? (like react storybook) Currently, I’m developing design system with jetpack compose with the team’s designers. When a new UI Component is developed, both designers and developers want to make sure that it is implemented as intented. For example, • To check how the UI Component looks in the number of cases in any state it can be (like enabled, disabled, selected) • To check which UI feedbacks (animations, state changes) are played when user interactions occur • … I’m communicating with the android studio preview of compose directly to the designers, but I want to know how to manage it more easily

@Composable
fun List<SecuritySensor>.asListOfRowImageText() = asList {
    RowImageText(
        leadingIconRes = it.icon,
        text = { it.description },
        textStyle = MaterialTheme.typography.body1
    )
}

@Composable
private fun <T> List<T>.asList(
    withDividers: Boolean = false,
    itemBuilder: @Composable (T) -> Unit,
) = Column {
    forEachIndexed { index, item ->
        itemBuilder(item)
        if (withDividers && index < lastIndex) {
            EvaDivider()
        }
    }
}

I am currently getting warning message:

Composable functions that return Unit should start with an uppercase letter

. Is there a better way of creating compose functions to avoid getting this message?

There was a section in documentation about integrating Compose in

RecyclerView

, what happened? We do not need to

setViewCompositionStrategy(ViewCompositionStrategy.DisposeOnViewTreeLifecycleDestroyed)

and

disposeComposition()

anymore?

Is there any way to preview a compose view on a nav graph xml?

I’m still struggling with displaying images from URL inside a

LazyColumn

with

coil

items(photos) { photo ->
    Card(
        modifier = Modifier.fillMaxWidth()
    ) {
        Column {
            Image(
                painter = rememberAsyncImagePainter(model = photo.url),
                contentDescription = "location image",
                contentScale = ContentScale.Crop,
                modifier = Modifier.fillMaxWidth()
                    .height(160.dp)
            )
            Text(
                text = photo.title,
                style = MaterialTheme.typography.h6,
                modifier = Modifier.padding(8.dp)
            )
            Text(
                text = "lat: ${photo.lat} / lon: ${photo.lon}",
                modifier = Modifier.padding(start = 8.dp, bottom = 16.dp)
            )
        }
    }
}

This is quite unstable, some picture loads and some doesn’t. Any idea what I’m doing wrong here?

Is there a way to listen to the Animations of

AnimatedContent

? Like if I want to get notified if an animation has finished. e.g.

AnimatedContent

gets new

targetState

, animates, calls my listener when animation has finished

I'm using HorizontalPager and listening to page updates as per the docs. This works well, but I also get notified when I programatically scroll. Is there a way to only listen to updates made by a user and not programatically? I saw the pager docs have something called Interaction source, but I couldn't figure out if its actually meant for my situation (docs dont really lead me to believe that it should be used for my case). Any suggestions?

Hello everyone. Is there a documentation anywhere about how exactly reusing in lazy layouts works behind the scenes? What is reused? Composition still needs to be re-done for every item, right?

On compose naming conventions: what would be the best name for the below method?

@Composable
fun ConfigureSystemBars(
    isContentDark: Boolean = defaultIsContentDark,
) {
    val systemUiController = rememberSystemUiController()
    val isDarkTheme = isSystemInDarkTheme()
    LaunchedEffect(isContentDark) {
        systemUiController.setSystemBarsColor(
            color = Color.Transparent,
            darkIcons = isContentDark && !isDarkTheme,
            isNavigationBarContrastEnforced = false,
        )
    }
}

It sort of feels (when using it in a component), like it’s displaying a component now. It’s not returning anything, so it cannot be called

configureSystemBars

(lower case).

Hello guy , can have been trying to create an otp validation screen having six(6) singled character outlinedtextfield and with the capability of pasting the recieve code on the fields

Hello guys, seems

set enabled

for modifier swipeable

Modifier.swipeable(enabled = false)

not work fine now, even set

enabled = false

SwipeableState.offset still keep changing any idea about this?

Anyone else had an issue if you have a BottomSheetDialogFragment with a ComposeView in the onCreateView that has a column with vertical scroll, that you cant scroll the content up without first doing a motion to scroll it down? (it drags the dialog down instead of scrolling the content up). I would assume that the scrollview would intercept the drag and scroll and not pass it to the parent dialog for dragging?

My textfield still hides behind the IME keyboard, why this is P4 issue I don’t understand. https://issuetracker.google.com/issues/192043120 any solution?

Can someone explain why

LocalConfiguration.current

line exists in

calculateWindowSizeClass(activity: Activity)

? Am I wrong in thinking that it does nothing here? 🤔 https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/[…]ndroidWindowSizeClass.android.kt;l=37?q=calculateWindowSi&sq=

Hey, I'm trying to create a simple to-do app, but I'm facing a state-related issue. There are 2 separate LazyColumns: One for completed tasks, another for incomplete. The data itself is stored in Room, but I'm also using MutableState for each item's TextField and CheckBox state. The 2 LazyColumns are recycling items' Mutable State (I think), even after retrieving updated lists from the database. Any pieces of advice? 😐

How can I use the TakePicture contract to take a picture and display it in Jetpack Compose? (Code in thread)

A

derivedStateOf

lambda walks out of a bar. The bartender waves and shouts, "Calculator!"

Has Anyone implemented In-App updates in any live *Jetpack Compose App*. if you have any references how to integrate in app. Please share. it would be of great help, Thanks in advance 🙂

LaunchedEffect not triggered when mutableStateOf has same value? I want to display a snackbar message when the user clicks on “Favorite Post” It works fine the first time but after that it is not getting triggered anymore. Here is my snackBarMessage State in ViewModel:

var snackBarMessage: MutableState<String?> = mutableStateOf(null)
    private set

and the set function:

fun setSnackbarMessage(msg: String?){
    snackBarMessage.value = null
    snackBarMessage.value = msg
}

Here is my Launcheffect which unfortunately is not getting triggered twice:

LaunchedEffect(key1 = viewModel.snackBarMessage.value){ 
    val message = viewModel.snackBarMessage.value
    message?.let {
        scaffoldState.snackbarHostState.showSnackbar(message, "Ok")
    }
}

and on Favorite button click I call:

viewModel.setSnackbarMessage("Added to Favorite")

Eventhough I set the snackBarMessage to null it is not getting retriggered, only if the string message is different from the one before. I want to show the snackbar every time the user clicks on the button and not just the first time

Hello, everyone 👋 I’m trying to setup compose in an existing project and I’m facing the following error:

NoSuchMethod: No Static method setContent

My dependencies:

dependencies {
    implementation("androidx.core:core-ktx:1.7.0")
    implementation("androidx.compose.ui:ui:1.1.1")
    implementation("androidx.compose.material:material:1.1.1")
    implementation("androidx.compose.ui:ui-tooling-preview:1.1.1")

Hi 🙂 I’m having some trouble with paddings/page resize when keyboard is opened, I’m attaching a video of the problem. It looks like if the TextField is in the very bottom of the screen, the imePadding does not work correctly. I’m using AdjustResize in my Manifest and

WindowCompat.setDecorFitsSystemWindows(window, false)

in MainActivity. My Column’s modifier is

modifier = Modifier
                    .fillMaxSize()
                    .padding(horizontal = MaterialTheme.spacing.medium)
                    .padding(paddingValues)
                    .consumedWindowInsets(paddingValues)
                    .imePadding()
                    .verticalScroll(rememberScrollState())

(Modifier.systemBarsPadding() is in the NavHost)

So i’m having trouble testing a TextField with a text style that has an explicit line height. I’m able to isolate this to a pretty simple test. It fails when i try to execute the done ime action, or if i try to do anything else on any node on the screen, including just printing the tree to a string. Removing the lineHeight attribute in the sample test allows the test to run properly

offset(5) should be less than line limit(0)
java.lang.IndexOutOfBoundsException: offset(5) should be less than line limit(0)

	at android.text.Layout.getHorizontal(Layout.java:1190)
	at android.text.Layout.getPrimaryHorizontal(Layout.java:1160)

See thread for test code.

any good reference to implement drag & drop(hold item put it next to other item) in lazyColumn?

In latest compose the “Animation duration scale” now affects the LazyList scroll animation (turning it off now causes jumps to end of scroll). Other apps (native or old compose) is not affected by it. Should this be considered as more correct?
