How am I supposed to preview composable function which invokes

viewModel()

function?

This is my implementation for

Marquee

. Is this correct?

@Composable
fun MarqueeText(announcement: String, marqueeSpeed: MarqueeSpeed, modifier: Modifier = Modifier) {
    val scrollState = rememberScrollState()
    val scope = remember { CoroutineScope(SupervisorJob() + Dispatchers.Main.immediate) }
    onDispose { scope.cancel() }
    ScrollableRow(scrollState = scrollState, modifier = modifier, children = {
        Row {
            repeat(1000) {
                Text(
                    text = announcement, maxLines = 1
                )
            }
        }
        val scrollBy = when (marqueeSpeed) {
            MarqueeSpeed.SLOW -> 2f
            MarqueeSpeed.MEDIUM -> 6f
            MarqueeSpeed.FAST -> 9f
        }
        scrollState.smoothScrollBy(scrollBy)
        scope.launch {
            while (true) {
                scrollState.smoothScrollBy(scrollBy)
                delay(50)
            }
        }

    })
}

How to use legacy xml layouts in compose? seems like

AndroidView(resId)

has been removed in the snapshot build. Should I use

LayoutInflator

inside viewblock?

Does Compose support Fragment Transitions with common Views? e.g. ImageView transitioning from LazyItem list to detail screen header, etc?

Guys, I have a questions about colors. I created a splash screen composable which is a constraintlayout with two Text() inside. Color of both of text components is setted to yellow. But when I get this screen on my app, both of them are blue. If I add backgroundColor to ConstraintLayout() it becomes also light blue. Anybody knows what is the problem? Maybe I need to add somewhere Surface()?

Is there any obvious reason why the modifier

drawOpacity

enables clipping in addition to the alpha value. From my point of view this seems to be a mistake, because it is not 100% clear from the modifier name or its description.

/**
 * Draw content with modified opacity (alpha) that may be less than 1.
 *
 * Example usage:
 * @sample androidx.compose.ui.samples.OpacitySample
 *
 * @param opacity the fraction of children's alpha value.
 */
@Stable
fun Modifier.drawOpacity(
    @FloatRange(from = 0.0, to = 1.0) opacity: Float
) = drawLayer(alpha = opacity, clip = true)

Hi, has

AppBarIcon

been removed?

Has anyone measured the compilation time of compose? I’m curious because I know compose uses a different version of the Kotlin compiler or something or other. I’m not exactly sure how it works, so I’m curious if there are any problems with it in terms of scaling compose in large projects.

What I'm doing wrong?

Does anyone know a good article/demo of focus management using Compose? I'm adding Compose into my existing tv app and I'm not able to move focus to my buttons using tv control

Hi! One question... What's the best way to have a list of themes? SO we can create a theme switcher

is there any compose counterpart of customlayout manager of recyclerview?

is there native way to calculate and apply diff to lazy column items like DiffUtils for recycler view?

has anyone built OTP Composable?

How to center text vertically?

Text(
                text = money,
                modifier = Modifier
                        .weight(.3f)
                        .wrapContentWidth(Alignment.End)
                        .wrapContentHeight(Alignment.CenterVertically),
                fontSize = 12.sp
        )

On a Samsung phone (SM-G960U1) I get a white line on the bottom of the screen with a grey pull-up bar. This does not happen on other android phones. Any way to overcome this in compose?

It seems that since 1.0.0-alpha05,

Text

is no longer selectable by default. How can we make it selectable again?

Why it is taking so long to fix the getValue/setValue auto import 🤔 ?

I'm just getting started with compose.. I want to interop with Flow.. But this doesn't render a list:

I have a weird problem with upgrading to alpha05. The elements inside

ConstraintLayout

will have a probability to be rendered or not. I also discovered this issue in Owl project.

Has anyone used Hilt with Compose? I'm willing to inject different instances of same type based on some condition. Also, is it possible to inject dependencies directly into a composable? I think 'Ambient' is another way of maintaining dependencies.

Hi Guys, Do we have dropdown spinner in Android Compose, I want to make Textfield with dropdown spinner to select the item in the country list . what are the options to make this ?

Hello, How could I find the sample provided in the source code through the

tag: just like:

@sample androidx.compose.animation.core.samples.KeyframesBuilderForPosition

.I did't find it in the github. Could anyone give me a link?Tanks a lot!

Is there hotkey to turn this

ButtonText(text = "Text", onClick = {}, modifier = Modifier.padding(top = 16.dp))

into this

ButtonText(
      text = "Text",
      onClick = {},
      modifier = Modifier.padding(top = 16.dp)
)

I am so tired to do this manually.

Hey, What should I use to show

horizontal progress

in compose. Should I use

slider

?

Has

navigation-compose

alpha released? Where can I track the new releases?

Scrolling lists via LazyColumnFor should have been significantly improved from alpha05. These lists are still slow in our projects however. Were anyone else able to notice significant improvements or the current state is still quite slow in your opinion? I’d like to hear your thoughts. Also hoping that the API still has a lot of points of performance improvement that can be theoretically worked on (I understand it’s currently an experimental API).
