Is there a way to add hints to TextFields yet? I've seen a few hacks on stack overflow but would like to avoid those if possible

Is there any way in a Text() to remove the top and bottom font's padding ? with a TextView we had

includeFontPadding = false

but I don't think there is any solution now...

Hi! Compose discussion? Is it possible to do this?

It doesn't look like 1.0.0-beta05 of Compose will work with Kotlin 1.5.0.....are there any short term plans to release a compatible version?

I am trying to create a simple horizontal divider on a Row but I cannot make it properly match the height of the parent. I can make it fully take the height by fillMaxHeight but I just want it to take the height of the Row.

I tried to make a floating window with androidx.compose.ui.platform.ComposeView

class FloatingService : Service() {
    
    private var windowManager: WindowManager? = null
    override fun onCreate() {
        super.onCreate()
        windowManager = ContextCompat.getSystemService(this, WindowManager::class.java)
        var view = LayoutInflater.from(this).inflate(R.layout.player_popup_close_overlay, null, false)
        val closeOverlayLayoutParams = buildCloseOverlayLayoutParams()
        var composeView = view.findViewById<ComposeView>(R.id.compose_view)
        composeView.setContent {
            Button(onClick = { }) {
                Text(text = "Click Me")
            }
        }
        Objects.requireNonNull(windowManager)?.addView(view, closeOverlayLayoutParams)
    }

}

Hi - I'm working on integrating a Compose component into a View-based screen - specifically within a

RecyclerView

. The Compose component loads several images internally, and I need to know (at a given moment in time) which of the images is 100% visible on screen. In the imperative, View-based world, we query for each image view's percent visibility on screen (i.e. using its position, width, height). Is there a good way to accomplish something like this in Compose?

When using the NavHost and NavController, what is the point of restricting yourself to passing ints and strings and other serializable args, when you can have a big ViewModel object with any kind of object in it, and pass that around by reference?

Can anyone tell me what scenarios

rememberUpdatedState

applies to? I saw

rememberUpdatedState

is used in Compose Dialog to remember content, but I still can’t understand what describes in kdoc. Could someone please explain it to me. I am grateful.

Just curious, how does Compose Compiler handle Composable invocation inside inline lambda passed to inline fun? for example,

list.forEach { MyComposable(it) }

AFAIK, I cannot know the body of external declaration stubs, like stdlib here. Also heard that inlining occurs in 'linking phase'. Then does compiler plugin generate an additional group for this loop?

Quick theoretical Compose question, ladies and gents. What situations would you ever use

remember{ mutableStateOf()}

instead of

rememberSaveable{ mutableStateOf()}

? If you get saving across configuration and process death with the latter, why ever use the former?

Hello All,

My app's firebase constantly getting

java.lang.RuntimeException: Canvas: trying to draw too large(116051928bytes) bitmap

, it seems when using accompanist to load a network image that is too large to load, is there any optimization we can do to avoid this exception?

Is there a faded edge effect that I can use? The best I can do now is to use a gradient paint of the background color, but that doesn't work when the background is more complicated.

Hi Devs, kindly guide me -> how to change the status bar color in jetpack compose. I tried some solution but failed.

I think I've found a compiler bug:

@Composable 
fun Foo() {
  val bar = @Composable { }
  // this works
  val bazOk = listOf(null, bar)

  // this doesn't
  val bazNotOk = listOf(null, @Composable { })
}

the non working line crashes with

KotlinFrontEndException: Exception while analyzing expression

. Should I file it or it's already reported? cc @Leland Richardson [G]

Hi ! Let's say I'm building a kind of

Restartable

Composable

. This component needs to be restarted when the user makes a restart request. In previous Android development, this could be achieved by calling on of

Restartable

methods, if

Restartable

was designed as a class. But, talking about

Composition

, what should be a good pattern to achieve this. More on my attempt in thread.

What do you guys thing about managing values like this? https://gist.github.com/cicerohellmann/4d67109876a6077d35a9a730aab2cc28 To use like this: https://gist.github.com/cicerohellmann/c4a40618c4045be116b9b14f9953b4df

Kotlin 1.5 support is coming sooooooon! (I know that 1.5-RC was in gerrit earlier too, but this is just straight 1.5) (also, the reason I'm so excited is that there are a few bugs I'm having with gradle7/agp7 thats supposedly fixed in 1.5. Can't wait till next week!) https://android-review.googlesource.com/c/platform/frameworks/support/+/1651538

Which is the lowest version of:

com.android.tools.build:gradle

and

//services.gradle.org/distributions/gradle

that can be used together? Do we have anywhere that could tell this?

How can i use

MediaRouteButton

in composables i want have the cast icon not in the actionbar but in my composable?

Is there a way to hook into the setter of a MutableState property of my ViewModel? When it changes I want to persist it, and clear other cached data in the ViewModel. (Code in thread.)

I can’t find out why I’m getting this error: : /Users/ch/brmvuroleticsandroid/app/src/main/java/de/rocketlane/uroletics/MainActivity.kt: (18, 13): @Composable invocations can only happen from the context of a @Composable function more inside the thread…

Please keep large code snippets in threads to prevent channel flooding!

Maybe this is a general Kotlin coroutine question. Is every code block passed to

viewModelScope.launch { }

run in the same thread? I'm wondering how to avoid loading data twice in my ViewModel. I could have a property there,

isLoading

, but I'm not sure how much I need to worry about thread safety.

Hello, could someone please help me understand why my columns are not the same size, considering I am using the same code for them? 🧵

hello, can i use compose in android widgets?

The docs say I can create a

NavController

using ``val navController = rememberNavController()`` . But when I create a navController this way I get

NavHostController

instead. It works fine for my

NavGraph

but I cannot use

.navigate()

on

NavHostController

. The docs do not include anything about the difference of these two or even mention

NavHostController

.
