If I were to make an app like this word finder game in Compose, what gesture detector would I need to use? As it stands I can get each letter using the onpress gesture detector , but I guess this is more of a swipe gesture. Is this possible in Compose or would I need to use a games engine? See picture in thread.

Is there something special in AlertDialogs and focus/keyboard?

LaunchedEffect(Unit) {
	focusRequester.requestFocus()
	keyboardController?.show()
}

Does not work I need to add a delay before the show() but this feels hacky and random value 😞

In general, will individual state variables be faster than a single data class that holds all the state for a screen? I know that when using individual variables, Compose will only re-render Composables that use the value of the variable that was changed. When using a single data class, is Compose smart enough to only re-render Composables that use the fields that changed, or will it re-render every Composable that uses any field of the single state variable?

with navigation animations via Accompanist library, does anyone know if there's a way to define your animation(s) at the time of calling

navController.navigate()

? my use case is that I have a dynamic screen which can be accessed by either tapping through the UI, and it can be nested many levels deep, and my animation for sliding in and out works great there, but this dynamic screen can also be accessed via the hamburger menu, and when it's accessed from there, I want to clear the backstack (which is the easy part) but I also want the transition to be different, because sliding in feels and looks totally wrong there is this possible? or will I need to create entirely different routes and

composable(transition = )

declarations and just use different routes to display the same screen but with alternate transition animations?

So, if i'm using the accompanist pager library, and I have a horizontal pager, I would like to add some sort of callback to know when the user actually swiped to change pages (as opposed to just a general change of pages which could also be triggered programmatically as say a response to a button click). I'm not sure how i'd do that, but my first instinct was a custom FlingBehavior, but that doesn't really seem to be the right thing. Is it even possible to get a callback like this? I also thought of setting a flag or something in the onClick callback to indicate if the button was clicked so that as i collect the changes in the pageState, i would know if it was a swipe or click.

Hi, Recently I have been trying Maps Compose https://twitter.com/i_am_rooparsh/status/1489892409534480386?s=21 Today, I noticed some strange behaviour in Maps. As per my emulator location spoofing, my location was supposed to be between 2 towns (Ludhiana and Patiala) which lie in India. But on maps, My location was shown somewhere in United States. On Further digging, I found that the issue was with latitude and longitude returned from Location class in gms package. Attaching a screen recording, wherein you can see lat and long that are in emulator and that my app is receiving. Not sure where the issue is .

I have a composable function that gets 3 State<T> params. Is it better to send State/MutableState in params or the value inside them?

Hi, Is Compose Animation’s

Crossfade

can do a subset of what

AnimateContent

can do? Or does

Crossfade

has more to offer that can’t be done by

AnimateContent

? (Just curious, why do we need a

Crossfade

function specifically, given looks like

AnimateContent

can achieve what

Crossfade

offers). More detail in https://stackoverflow.com/questions/71006883/is-jetpack-compose-crossfade-just-a-subset-functionality-of-animatecontent Thanks.

What’s the best way to get a callback when an item is 100% visible in a

How to create a custom layout with AndroidView?. For some reason, the measured height of the AndroidView occupies all height. I checked, and it is the wrapper view that has that size. The real view has it’s size correct. Any help ?

Is there a way to wrap the content of the TextField below minimum width, which I've found out in source to be

280.dp

? So I want width to wrap around letters as you enter them and delete. I've been trying to resolve this for days. It just seems there's no solutions.

Is there a way to implement a sort of recursive navigation route with compose navigation? In this app, you can navigate to, e.g.

topics/topic1

, or

topics/topic1/topics/topic2

. The depth of recursion is undefined.. I’m not sure how to implement this, as implementing a composable for each possible level, e.g.

composable(topic/{topicId}/subTopic{subTopicId}/moreSubtopic/{moreSubTopicId}

doesn’t seem practical

If I know that a variable is `@Immutable`; but I cant mark it directly myself - is there another way to acheive the same thing/optimizations? 🧵👀

Hello is there any way to test with compose-ui-test that a Text has the text color that I expect? Or a Row/Column that has the background color that I expect?

Hi! Does compose navigation support deep link with multiple domains?

Is there something akin to

.replace

that works on

TextFieldValue

(takes cursor / selection into account)? I'm trying to have forbidden characters (like @) in my

TextField

so I'm just doing

.replace("@", "")

inside

onValueChange

but this means the cursor will stay on the position of the removed character (i.e. behaves like "insert" key is on). I feel this is simple to solve, but just wanted to check if there's some builtin method I'm missing.

So, i’m having an interesting issue that i’m not sure is technically a compose bug or an android studio bug. If i create a view that extends AbstractComposeView, and then reference that in an xml file, i can’t get a preview, and see this error. Looking for input on wherew to submit this bug. (for the record, i’m using ConstraintLayout 2.0.4)

Hey all, can someone explain to me in layman terms what this means.: Jetpack Compose is an instrumentation test,you can use a test framework such as Espresso. thanks

Guys, is there a way to enable/disable the OS back button but not to override the default behaviour? The only thing that is available right now is this

BackHandler(!state.isLoading) {}

If I do like this, the back button doesn't work even if the

isLoading

variable is

false

.

Wrapping a

I get from Room into either a

SharedFlow

or a

seems to prevent it from working (I get the initial list of items from Room, but it never updates). What could be causing this? (code in first reply)

Hey all, trying to write some tests. Can I get some help with the method please. thanks

Hello everyone, 👋 I was wondering if anyone has any suggestions on the best way to approach building a curved/arced horizontally scrolling list of items with "Snap to Center" behavior + having the beginning of the list positioned in the center of the screen. I've found an article that does something like what I am trying to do, but with RecyclerView + custom layout manager. Posted gif from link below for quick reference as well.

Hey, have you ever had any problems or weird behaviours when chaining modifiers? I’m passing

Modifier.requiredSize(50.dp)

to

MyTestComposable

, and I expected that I would override the size with the new value -

50.dp

. And yeah, the size is being modified, but somehow when I try to use

MyTestComposable

in a Column it looks like another view is being drawn on top of

MyTestComposable

- take a look at the picture attached in thread.

@Composable
private fun MyTestComposable(
    modifier: Modifier = Modifier,
) {
    Box(
        modifier = Modifier
            .border(1.dp, Color.Blue)
            .requiredSize(25.dp)
            .then(modifier)        ,
    )
}

Hi all, when using a

Scaffold

how can we get the

TopAppBar

and

BottomAppBar

to be transparent and have the body background visible top and bottom?

I can use

maxLines = 5

on a

Text

to limit it to 5 lines, but how do I make it always take the space of 5 lines, even if there is less text? I'm looking for a

minLines = 5

, if there was one.

Hi, does TextField always keep focus? I want it to loose focus whenever I click outside of it but that isn't happening. Even when I open a dialog box, after the dialog box closes it keeps focus. How can I remove TextField focus whenever I click outside of it?

Hi, I build the app complete app using jetpack compose now we need to add tooltips for onboarding which looks kind of overlay on the UI as shown in the screenshot. Any Idea how to build it. Should I use a constraint layout and create overlay Ui on each screen

Hi @Doris Liu, an animation related inquiry. I can’t seems to find any additional benefit of

MutableStateTransition

compare to normal
