Hey! Does compose support

fitsSystemWindows

flag? The

TopAppBar

is being displayed below status bar, and needs to be shift below device status bar.

Sometimes designers use "lineHeight" attribute in Figma to expand a text style height. For example on the below image textSize is

15dp

, but lineHeight is

24dp

. And that's used across all screens (UiKit). How would you encode this universally with Compose?

TextStyle.lineHeight

works only on paragraphs, and setting

Modifier.height(24.dp)

on

Text

doesn't center it vertically inside. So far the only solution that works is having a

Box

around the text, but that feels like rather verbose solution... or not? UPD. screen shot in the thread

Hi! I’m attempting to animate item entry and exit in a

Row

with

AnimatedVisibility

,

expandHorizontally

, and

shrinkHorizontally

.

shrinkHorizontally

works just fine, but

expandHorizontally

unexpectedly moves the content vertically too. If I lock the row height to the same height as the items, the item doesn’t move as much but it still jiggles a bit. Am I missing something or is this a bug?

(Compose Ui/Android) How can I lay

Dialog

under the system decorators(status bar etc.)? I enabled

setDecorFitsSystemWindows

and I want to implement full screen dialog. I saw in

1.0.0-rc01

usePlatformDefaultWidth

is added so I can fit full width and height(excluding decors) but cannot fully implement full screen dialog.

What do you guys think of that spinner? And also can I center the text ('m using BasicTextField because of some bugs with the other ones)

Is there an easy way to put a vertical grid inside a

LazyColumn

? Using

LazyVerticalGrid

throws an exception which says I cannot use two scrollable layouts in one direction & I cannot find a non scrollable version of

Grid

to use. I do not want to grid scroll independently, I just want to put a grid inside my

LazyColumn

. I know I can manually implement it using Rows & Columns but I am trying to avoid that especially since my grid is adaptive and the number of items on each row depend on the device.

I have a ComposeView in a Fragment, that doesn't get it's state restored when from popping the back stack for a fragment transaction. I've tried using an XML with an id set on the ComposeView which normally would save view state for non-compose views. This is resetting my LazyColumn position to the top. I can work around it by having a LazyListState in the Fragment ViewModel. Having to save all view state in the VM to be restored when popping the back stack doesn't seem optimal. Am I doing something wrong?

Is there a way to add a touch listener to a composable, which is called even if the touch started outside of the composable? i.e. when I press down on a star in a rating bar, and drag my finger to another star, I want to register a touch event in that other star to update the rating.

Is it possible to apply a transform matrix on

ComposePath

directly? I would like to draw multiple paths with different transform matrices (including scale and rotation). but I am not sure how to draw it correctly in Compose

I am having weird behaviour with

BoxWithConstraints

composable. The closure that is being passed to it gets called multiple times with the height being different values each times. There is no animation or no state that can cause it to be recomposed. P.S. I am using

1.0.0-rc01

version of compose. The code and stack trace in 🧵

I have a list of items composed via LazyColumn. If any one of the item gets changed in the list, how can I make sure only that particular item of LazyColumn gets recomposed instead of the entire LazyColumn.

Can we have some tooling to count recompositions by screen areas?

I have Column > Box > Column hierarchy. All have

fillMaxSize

modifier, while box also has

verticalScroll

. As soon as box has scroll, its child column can no longer be at max size. Is this expected? Feels like a bug to me. Screenshots and code in thread

I have two types of approaches, which is good? Code in thread 🧵

Hey everyone, is there no way to get the scroll offset from the start of a LazyList?

val lazyListState = rememberLazyListState()

Here

lazyListState

only has the properties

firstVisibleItemScrollOffset

and

firstVisibleItemIndex

. The

firstVisibleItemScrollOffset

resets to 0 after each item scroll. I know I can do

firstVisibleItemScrollOffset + firstVisibleItemIndex ª itemHeight

, but sometimes getting the

itemHeight

is tricky or impossible

How do we change the screen orientation dynamically in compose? @Adam Powell @Andrey Kulikov

Is it possible to create home screen widgets using compose? Has anyone tried it?

I have a question about testing. I'm using IntentsTestRule to start "Activity1". When i click there on a button "Activity2" will open. Now i want to verify that Activity2 is shown by checking if a String is displayed. Activity2 is using Compose, Activity1 classic Views. I can't find the String, because inside the View Hierarchy of Actvity2 is only a AndroidComposeView. Is there any way to make a Composable findable for the "normal" Espresso assertions?

Hi @Doris Liu, just wondering if there is any guide around animating TextSize change? Would it be enough to simply create a

State

holder for the font size? Just would want to be sure that this is the correct way since with `View`s (Correct me if I’m wrong), animating the font size directly isn’t the suggested (optimize) way of doing it.

I show a

Dialog

when the user clicks on an item in a

LazyColumn

. Is there a way to make the

Dialog

's position depend on the items position? Basically showing the dialog above/below the item instead of in the center of the screen.

Does it possible using UI Automator on Jetpack Compose UI?

is it possible to make Text() font size fixed (not scale with font scale)?

Hi, how can I modify the color of a Button when clicked ?

AnimatedImageVector has been temporarily removed in rc01. Will it be added back in rc02 or later? I wasn't able to find any information and it is still mentioned in the resources compose documentation. Thank you!

A small Typo In Official Documentation... :blob-thinking-upside-down: How to report it ?

Is it possible to anchor a snackbar to a FAB in Compose, preferably using scaffolds? I'm looking for a similar behaviour we can implement this using CoordinatorLayout, which the snackbar pushes the FAB up when it shows.

I have a method with the signature :

fun map(name: String): @Composable ()->Unit

. I need to generate this function using

KotlinPoet

but I can’t add

@Composable

to the return type, any clues how to do it ?

Does retaining a scroll position of a LazyRow via LazyListState work without compose navigation?

why its not possible to preview a AlertDialog? is there a way to do it? i use for preview the beta09 in android studio bumblebee canary 3? or is there a bug?
