I would like to ask, what is the latest Compose implementation of pan and rotate animation?

I’m trying to adjust the

TextField

size so it’s adjusting to the size of the text that’s currently set. I thought that

wrapContentSize()

would do the job but I couldn’t be more wrong 😬 So having this:

TextField(
        modifier = Modifier.wrapContentSize(),
        textStyle = TextStyle(textAlign = TextAlign.End),
        value = text,
        onValueChange = { text = it },
        label = { Text("Label") }
    )

Gave me such result in preview 👇 which arises 2 questions: 1. Why

TextAlign.End

set it around 40% of the width and what is the empty space behind it? 2. Why

Modifier.wrapContentSize()

doesn’t wrap it around the value or label at least? 🤔

I've been running some experiments based on the excellent post by @Zach Klippenstein (he/him) [MOD] regarding scope of recomposition. I feel like I'm getting different results, and I'm not sure where I'm going wrong in my analysis. Details in 🧵 .

I updated to AS Canary 14 (no release notes?) and it prompted me to upgrade the android gradle plugin AND move to gradle 7.0 RC 1. Is that mandatory? Is anyone using gradle 7 RC 1 and any risks?

I have some strange behavior. I have 2 view models which both extend from a base view model. The base view model holds state:

var uiState: UiState by mutableStateOf(UiState.Loading)
        private set

I also have 2 screens, each of them uses its own view model. viewModelScreenA and viewModelScreenB. When I print the uiState in both view models like:

init {
        Timber.e("VM A - uiState: $uiState")
    }

The uiState of both view models are identical

UiState$Loading@220c954

. I would expect that they are different, not?

Should I use

FloatTweenSpec

or

tween<Float>

, …

FloatSpringSpec

or

spring<Float>

?

Hello, everyone! 👋 I’m facing some issues with Compose and SplitScreen support. When my application first loads in Split Screen, it works fine. But if I try to resize it, the UI no longer loads. If I resize for a second time, it loads again. Basically, the first resize does work, the second does not, the third does works and goes on. Is it a Compose issue? Am I doing something wrong? Could someone help me, please? Thanks a lot in advance. ❤️

I noticed a problem with

tryAwaitRelease()

on beta04. It’s always returning false… 🤔

I've got yet another problem, sigh... I have a rectangle that covers the whole canvas. I am using detectTapGestures to detect presses. When I press somewhere within the rectangle, I only get success some of the time - it's really inconsistent. I have no idea what is wrong with my simple code. Any ideas? Code in thread.

Has anyone ran into the Bottom Sheet automatically expanding in the

BottomSheetScaffold

? Video of the erroneous behaviour in the thread.

What version of

kotlin-gradle-plugin

are we meant to be using? I'm on 1.4.32 and experiencing some ... issues

one question how can i bind a service before setcontent in MainActvity? i have a exoplayer instance i create in service. and want to give ist to my mainscreen in the set content in oncreate? i implement the way google recommend but in oncreate my player instance is every time null

ClickableText does not seem to work inside of SelectionContainer. I assume this a bug? I'm fairly sure it was working at one point (pre-beta).

Is there a way to get the marker annotations (particularly

@Immutable

) in a separate, common artifact? I have some data definitions in a common module that doesn't have compose dependencies, and would like to mark them as immutable.

How do you set the maximum value for a manually-controlled scroll? I can’t set the

maxValue

on

ScrollState

because it’s internal… I’m using

verticalScroll

modifier on my component, but can’t figure out how to set its limits…

I have a (quite) complex composable compound of several pieces modifying a common state. I'd like to avoid giving plenty of callbacks everywhere in favor of centralizing such logic in a "state" object consumed by all my composables. I can't make it work so far. I think I read somewhere how to deal with that, to avoid tons of

value, onValueChanged: () -> Unit

, extract it in a "state". Does it ring a bell to someone? Any advice on how to manage my use case? (I can detail more if needed)

I have a custom

Layout

component, that does all the measurements and placements. Now, I want to draw some adornments on the canvas, kinda like

drawBehind

, but I need to know placements of the children. How would I do it?

One thing I'm having really difficulties with compose is naming. How do I name my things? Let's say I have a counter: Intuitively, I'd create a function called:

@Compsable fun Counter()

But now I need to separate the logic and UI and need to create a counter class that is the actual counter and not the ui. Intuitively I'd call that counter

class Counter

. Now having both of these named the same is obviously a bad idea, but what's the solution to this? Consistently suffixing every composable ui function as

CounterUI

? Or

CounterView

? How do you handle this?

Any idea why "Deploy Preview" button of a

@Preview

is grayed out and inactive? Using AS Canary 14 with Compose

beta04

(tried

beta03

- same thing). Is this a known issue?

Hi ! Looking at https://developer.android.com/jetpack/compose/state, it is written that we may need to create custom object saver to pass custom data to

rememberSaveable

, but how should I build such object ? Let's say for

data class Point(val x: Int, val y:Int)

? Because there is not any example in the documentation, and I did not understand this sentence (

build a custom object saver

), what interface should the saver have ? What is the Android class/object responsible for such interface ? Should I create a

Bundle

myself ?

I see that many people do games with Compose, including myself :) may be we need #compose-gamedev? I’m not totally sure, just asking for crowd wisdom. #gamedev looks too broad. Or may be not?

I'm running in a kind-of state problem. I have an audiobook player. On the playback screen I show a Slider with the current position in the chapter. The backing state periodically emits with the current position. So for the slider value, I can't just use remember, else while playing, the track would not be updated. Instead I have passed the current time as the key to the remember function. In theory this works. However when you try to seek while on playback, the slider continues to be updated which causes visual glitches. Any idea how I can come around that? Here is my current implementation: https://github.com/PaulWoitaschek/Voice/blob/aad9fd7eafe734e739b7e20e4d908f242a95ce51/playbackScreen/src/main/java/voice/playbackScreen/views/PlaybackSlider.kt

I'm having some weird behavior with

IntrinsicSize

and

Arrangement.SpacedBy

(code in thread)

has anyone seen decent examples of master/detail apps built with Compose? looking at building something which I’d like to run on both phones and tablets with a slightly enhanced tablet view. last time I had to do this was before Android Architecture components even existed (so pre-ViewModel etc).. I’m wondering if anyone has seen anything with a master/detail tablet view which is using modern architecture, and specifically Compose?

I'm looking for a specific function that allows to make multiple changes to a state before recompose is triggered. I can't find it. Can someone help?

Is it possible to configure a LazyColumn/Row to always snap to discrete item positions after a scroll? It looks like this was possible previously with

FlingConfig

(now

FlingBehaviour

?) but I cant see how I can specify a list of anchors or snap points easily

help composers, why this is not animating ? I put log statement which gets printed with the changing float values (1f to 1.5f)

Wrote about my experience using Compose to write an animated collapsable button (https://abhishekdewan101.github.io/learning-to-code/blog/Animating/). Compared to the old system, I found the way of thinking of animation in compose easier to get used to.
