I setup my content in composeTestRule in

@Before

composeTestRule.setContent {
    MainNavHost()
}

How can I finish the activity completely in

@After

I tried

composeTestRule.activity.finish()

But that hangs forever

Does anyone know the rationale behind not exposing any semantic properties for text styles? All i seem to be able to validate is the text string, but not the font size, font family, etc….

Facing a strange text issue and wondering what could explain it that I may be doing wrong.

👋 I get this exception on a release build only, when using an abstactcomposeview inside a coordinator layout

ViewTreeLifecycleOwner not found from androidx.coordinatorlayout.widget.CoordinatorLayout

Is this a known issue? Any [G] here that might help perhaps? I can see similar issues on issue tracker, but all recommended that appcompat 1.3+ would fix this, but I am seeing in on 1.41.

Hello everyone, how do we test

Modifier

,

text styles

and

drawables

in compose

Hello, is there a way to apply a rotation animation with an anchor point? So far, all modifiers I've found apply the rotation at the center. There is a

rotationMatrix

method where you can specify your anchor point but I don't think it's supported by Compose yet. Am I missing something?

I have a layout where I have some common content outside of my navHost which works fine except I have some nav routes where we don’t want to display the components outside of the navHost so I’m hiding them. I have this working fine except, the animation for hiding the stuff outside of the navHost happens before the navigation within the navhost completes which results in a really bad looking transition. I was wondering if anyone else had found a good way to solve this. Details and code examples in 🧵

I need to animate item additions/removals in a

LazyColumn

, which is currently not a built-in functionality (issue: https://issuetracker.google.com/issues/150812265). How are other people solving this? No animation is quite jarring and waiting a few months for an official implementation doesn't really work.

hi all, when using compose i have the following

BoxWithConstraints {
   Image(painter = painterResource(id = R.drawable.image), contentDescription = null)
}

how can i make the image

width == parent's width

but the height to keep a constant ration as the original image?

when using `ModalBottomSheetLayout`*,* is there a straightforward way to catch a press of the back button and just dismiss the bottom sheet, rather than navigating back entirely? at the moment when I hit back, the entire screen behind the

ModalBottomSheetLayout

is popped too, and I'm trying to avoid that behaviour

⁉️ I am having trouble with

ComposeTestRule#advanceTimeBy

method. It doesn’t work as expected with animations. ▶️ Here’s more details : https://stackoverflow.com/questions/70982285/compose-advancetimeby-doesnt-work-with-animation.

Can we add extension function like

SpacedBy(4.dp) { Content() }

for

ColumnScope

and

RowScope

?

My app has 4 tabs at the bottom. On Tab1Screen I'm using a ModalBottomSheetLayout, but the "Modal" shows beneath my tabs. Is there a way to change the "z-index" of my Modal so that it shows up on top of my bottom tabs so that it's a "proper" modal?

Why would a

SaveableStateHolder

fail to save/restore the state of a

LazyList

? Ive verified that my keys are correct, and Ive stripped out any surrounding logic, yet it doesnt do its thing.

Hey, is there any way of chaining multiple animations depending on each other? Let’s say I want to animate both view’s X offset and it’s size, but the size should start animating after X offset’s animation is finished. Wondering what’s the best approach here

Hey, I have a tricky problem. I need a

Pager

in Compose that wraps its content (so the pager has the height of the largest child). I used Horizontal Pager from Accompanist, however since it is based on

LazyList

only the current item is measured and used for height calculation. If now the children have different heights this causes the content below the pager to jump around see video. So far my ideas: • Forcing the

LazyList

to measure/draw also items that are not visible (this is possible for RecyclerView), so far I could not find anything in the implementation source code to enable this behaviour. But maybe one of you has an idea? • Using

Row

instead of

LazyList

. I have an PoC for this, but it resulted in a lot of code since I had to implement Snapper for normal Rows and currently it is still a little bit buggy. I’m happy for every hint on this topic 🙂

When I add a label to my text field while it's on the screen, it shifts down just ever so slightly (to make room for the floating label text). Is there anyway to get it so that it's always at its max height so to speak even if the label is blank?

So, i’m experimenting with wrapping some of my composables in View classes to bridge the gap between the xml world and the compose world. Yes, programmers could put a raw ComposeView in and set the stuff in code, but it’s more convenient for them this way. I figured i would write a view that extends FrameLayout and adds a compose view, reads xml attribute and renders the contents of the ComposeView based on those. This works all well and good, except that it breaks the xml preview. The preview pane complains that it can’t find the viewTreeLifecycleOwner during the recomposer creation. Code and error screenshot in thread.

hi, I’m trying to pass string argument in navgraph, its crashing even after encoding more in the thread

Can I enable logging for

AsyncImage

in coil-compose?

This is probably something silly, but I just can't find a solution: I have a scrolling column of cards, with a header with a shadow (elevation) at the top (screenshot 1). For some reason, the header's shadow is not visible when a card is under it (screenshot 2). Why is that? How to fix it?

Anyone else getting java.lang.AbstractMethodError when building minified builds? This started happening when upgrading gradle to 7.1.0. When I disable obfuscation in proguard-rules.pro this exception doesn't happen. I've tried both compose 1.1.0-rc03 and 1.0.5. Thanks!

if I have a NavDrawer whose content is largely dynamic (let's say 75% of the items in it come from our API), is it a reasonable thing to do to create a ViewModel for the drawer itself? most of the code I've seen demonstrating NavDrawers in Compose all have static hardcoded items, but my use case requires dynamic content and it feels right to have a NavDrawerViewModel to manage it. does this seem like a good idea?

Hi, I have multiple textfields that can be errored, and I have a button to validate everything, and I want to only enable the validate button when no fields are errored, so I created a first-class array of strings, and when an field is errored, the name of the field is added to the array, and my button has the property

enabled = array.isEmpty()

but the problem is that the button enabled state is only updated after the array has changed Like if I have a field errored, the array has correctly a new value inside, but the button is only updated when the list is updated after this (like adding/removing an element), not directly when a new element is added to array

open class A(
    open val a: Int,
    val b: String = "Something"
)

data class B(
    override val a: Int = 20,
    val c: Int = 30
) : A(a)

I have a composable which is dependant upon

class B

.

@Composable
fun BCard(b: B) {
    // Compose something
}

BCard

recomposes when

a

nad

c

are changed, but not when

b

is changed. How can I solve this?

Why

Color.White

doesn’t work? but other colors like

Color.Red

or

Color.Blue

works! 🧵

I have seen some discussions around avoiding architecture component view models in pure compose apps because these ViewModels only work in Android. Does that also mean I should avoid Hilt as well? If yes, what is the recommended way of dependency injection in such apps?

Anyone running Compose app on old devices (2015/2016)? I'm finding it visually slow.
