kotlinlang #compose

Is it possible to “clearContent” before starting it again? Some of my tests are flaky because I need to mix it up with Espresso. ☹️ Thanks in advance!

one question ! How can i use my own imported svg in a icon?

Icon(
    imageVector = Icons.Default.PlayArrow,
    modifier = Modifier.padding(8.dp),
    contentDescription = null,
)

but i want the pause icon from the material icon without to import the whole lib ? how can i get a ImageVector from painterResource?

🧵 I have one query related to "transitionState" for animations in jetpack compose. I have created an expandable list which on the icon click expands and collapse, which certain animations. What i'm seeing is that the Composable function which shows expanded content, is being executed 4 times. And that is the same number of transition i'm applying.

I’m using a nested nav graph called “authenticated” to represent all the authenticated routes of my app. I want launch some tasks (fetch data, connect to a bluetooth device) when the user navigates to any route within this nested graph. Since

NavGraphBuilder.navigation

is an extension function and not a composable, I can’t see any way call

LaunchedEffect

from a nested graph. Do I need to use nested NavHost’s here instead?

Does Beta means one still needs to run arctic fox to run Compose with Preview?

Just want to say a very big congratulations on this HUGE milestone! This has been a monumental undertaking and y’all have stayed on track so far. This gives me full confidence that even if there’s something critical missing, y’all will take care of it in time. Even the community that’s formed around this is special and I’ve enjoyed being a part of it. Excited about the rest of the year and how we form more opinions around Compose 🥳 👏🏼

Updated to beta01, can’t find

anymore, there’s no info about it in the changelog AFAIK.

Is Android Studio Arctic Fox suitable for production use? If it isn't, that still means that Compose can't be used for production 😔

Since the

DrawerState.open()

is now

suspend

, is there a new recommended way to open it from the onclick of the menu Icon? I suppose there is a better way than

GlobalScope.launch

In alpha12 I used the factory function

FlingConfig

which produces function

adjustTarget

from the list of

anchors

. Do I need to recreate it manually now or is there an analogue?

What's the difference between

Button(onClick = {})

and

Button(modifier = Modifier.clickable {})

? Any reason why there are two different API's for telling the button what to do on click? Which one do people generally use?

Bummer. I can’t use Compose because it requires IR, but my app crashes with IR enabled due to my use of Kotlin.Result (https://youtrack.jetbrains.com/issue/KT-44722). And the fix won’t be released until 1.5. 😞

Hello. I am very excited about the release of Compose Beta. I am reading new documentation and noticed on some topics values that represent size or offsets used as raw values without conversion from DP to Pixels. Was this intentional or by mistake? Thanks.

Previously there was

pressIndicatorGesture

, I am using this to immitate that :

Modifier.pointerInput(Unit) {
    detectTapGestures(
        onLongPress = { doingSomething }
    )
}

how can I listen when you have left/cancel the long press?

You could add an

onPress

handler invoking

awaitRelease

, or more simply, just writing the code after

detectTapGestures

returns may work for you.

With either approach, you will probably need to add an extra variable like

var didLongPress = false

and set it in your long-press handler in order to distinguish long presses from other types of presses

Thank you @Alexandre Elias [G], I used for my usecase like this:

Modifier.pointerInput(Unit) {
        detectTapGestures(
            onLongPress = {
                doingSomething(true)
            },
            onPress = {
                doingSomething(true)
                if (this.tryAwaitRelease()) {
                    doingSomething(false)
                }
            }
        )
    }

I used

tryAwaitRelease()

as it returned me a boolean value to check when gesture is cancelled
