How can I properly convert a

androidx.compose.ui.text.TextStyle

to

androidx.graphics.Typeface

? I'm currently doing:

val fontResourceId = ((textStyle.fontFamily as FontListFontFamily).fonts[0] as ResourceFont).resId // a lot of doubts about this
val typeface = ResourcesCompat.getFont(context, fontResourceId)

I need to ellipsize text at start, but this isn't possible yet, so I just draw that on a

Canvas

. Code in thread

I'm looking to create something similar to Threads, the Instagram messenger as a transition/animation exercise alongside routing. I'm trying to figure out how to expand a new page from the position of a list item and transition it cleanly. It seems that a lot of the animation APIs are kind of high level. Is there a good way to get positional data of a list item and share it to choreograph a transition?

Do I need to set up some kind of registry for

rememberSaveable

to work? I stopped using the standard `NavController`/`NavHost` and now it (and

rememberLazyListState

) stopped working.

Hi there, is there a way to propagate a click event to a Composable with a z-index inferior to the current one ?

how to collapse

bottomsheet

in compose when

backpressed

I was using a

BottomDrawer

but that gave me issues when the content was scrollable (swiping would actually show the drawer instead of scrolling my content), so I migrated to a

BottomSheetScaffold

, but I don't seem to find away to add a scrim/darkened layer when the bottom sheet is showing like

BottomDrawer

does. Is this not supported by

BottomSheetScaffold

?

Does anyone know why the bottom of the lazyColumn is incomplete?

I’m using the

HorizontalPager

from accompanist library. In version

0.9.0

the

offscreenLimit

parameter was removed, but it’s still in the docs… Is there any replacement for this param? cc: @cb

I would like to preview my screen content which expects a view model/presenter (custom class) object. I have made interfaces for this but I'm a bit lost how to fake the presenter object or is the suggested way to instantiate the presenter object here directly (but which leads to a render problem)?

@Preview
@Composable
private fun Preview() {
    MyTheme {
        DashboardContent(
            scaffoldState = rememberScaffoldState(),
            appBarTitle = "Preview",
            presenter = // TODO
        )
    }
}

Has anybody been able to use exoplayer to play video in a LazyColumn and scroll smoothly?

How do you run things at the end of an animation? I'm probably thinking about this wrong, but I want to use

Animatable

to move a Float from 0 to 1.0 and then set some state to null at the end. I thought

animateTo

might have an

onDone

block, but no.

Hi, I have two questions about my code. 1. at the end, when I measure the x offset of my Tile, how do I reference the maxWidth of my parent Box? 2. how can I make sure that each Tile is dragged individually rather than as a group? 🧵

Can anyone tell me how to use

BackHandler

? I want to use it to collapse

ModalBottomSheet

, but I didn't find a good way to use it

So far what's the general approach to placing a

TopAppBar

in a general case where every screen of an app has one. Do we create a single

TopAppBar

and mutate the title and menus via events or we'd rather have a

TopAppBar

defined in each screen? What bothers me in the second option is that if you animate the transition between screens, the

TopAppBar

will also be animated (I haven't looked into transition animations yet) unless we do something more custom for the app bar itself. And there are cases where the

TopAppBar

shouldn't be animated and only its title and/or menus should be updated when changing screens.

The first time I tap on my

TextField

its bottom is not fully visible but after that one time it works fine. Is this a bug or I am doing something wrong? [Gif in thread]

Hi, I was wondering what does it mean when you call

subcompose(...)

inside

SubcomposeLayout(…)

? Is there a good source that dives deep into

SubcomposeLayout

? Thanks in advance.

Looking to build some intuition around when props are specified as direct composable function parameters vs as modifiers. Is there a good rule of thumb to get started with?

Would creating compose bindings for flutter (or some layer of the flutter stack) be a potential way to get compose-ui displaying on iOS? I know nothing about the internal work that would be required. Has something like this already been experimented with?

HI , I have a list of items in lazy column view. How we can show animation when we are removing the one item from the list. I need to animate the view which is getting deleted. The delete operation is done by pressing the delete icon inside the view.

From a small portion of a composable to the initial clip rect of the composable?

The latest edition of Code Magazine has Jetpack Compose on the cover 😄 Wasn’t expecting it to be the cover story when I first wrote that article but I’ll happily take it. You can find the digital edition here - https://www.codemag.com/Magazine/Issue/MayJun21.

Hi, I'm still working on my custom layout and I have a question. The Layout modifier applies to the whole layout, unsurprisingly. If I wanted the modifier to apply to each of the placeables, how would I go about it? For instance, in the case of a

draggable

modifier, I don't really want the whole layout to be dragged, but only the individual elements of the layout. I have posted this on 😒tackoverflow:, if anyone wanted to have a look... https://stackoverflow.com/questions/67457124/how-to-apply-the-layout-modifier-to-each-placeable-individually-in-jetpack-compo . Thanks! 😊

I do not know if anyone faces same problem like I. I am using coil for Image loading and I am using rememberCoilPainter and passing an Image url. Previewing or running on device shows nothing. I have even used the deprecated CoilImage and I still have the same issue

Hello all, How to save

Color

to

room db

in Jetpack Compose?. I’m trying to save an Article to room db (One of the params is

Compose Color

). Currently it shows error like to Use

TypeConverter

for

color

field to save the data. How to achieve this?. Below I’ve attached my Model class.

Any suggestions on what is the best way to migrate a project to compose? The project is modularized by feature and uses single activity and navigation component to navigate between fragments via deep links. I know that I should keep the fragments as wrappers for composables until the whole app is fully migrated but from where should I start the migration process? The app uses bottom navigation which is being setup using the navigation component. How can I convert the bottom nav to a compose UI and set it up with the navigation component?

Hi, does anybody know how to do styling + formatted arguments with text that is being shown in a text composable? The use case is to just bold two items in the string which are getting fed in with format strings. Options in thread.

Hey folks! Is there any particular reason why

@Preview

annotation has

@Retention(AnnotationRetention.SOURCE)

but not

RUNTIME

? I'm trying to build a component gallery app, and would like to find all the Preview composables using reflection. Unfortunately I cannot do it right now without using codegen. Would it make sense for me to send a PR changing retention from

SOURCE

to

RUNTIME

?

Hi. Is it possible to use text alignments (i.e.

textAlign = TextAlign.Center

) with

ClickableText

(see https://developer.android.com/jetpack/compose/text)? The

ClickableText

API seems not to support it. My goal is to have hyperlinks on some of the words, like this: https://stackoverflow.com/a/65656351/674487 , but I would like the text to be centered
