Is

Box

the recommended way of creating simple shapes such as this BottomSheet handle?

Does kotlin build-1.4-M2-eap-70 support compose 0.1.0-dev10?

Hi folks, there is anyway to load a Compose FontFamily from a set of files in the device that was downloaded ?

Am I doing something wrong or onSelected in BottomNavigationItem is not working? 🤔

BottomNavigationItem(
    modifier = Modifier.fillMaxWidth()
            + Modifier.ripple(enabled = false),
    alwaysShowLabels = true,
    icon = { Icon(vectorResource(item.first)) },
    text = { Text(stringResource(item.second)) } },
    selected = selectedItem == item,
    onSelected = {
        println("println statement that is not getting called")
    }
)

I am trying to use observeAsState on a LiveData, but I am getting:

Type 'State<List<MuNowNext>>' has no method 'getValue(Nothing?, KProperty<*>)' and thus it cannot serve as a delegate

I don't get that error message. I see State has this extension:

State<T>.getValue(thisObj: Any?, property: KProperty<*>)

An Nothing? is not Any?, so why does it want a Nothing? ? Code is:

@Composable
fun ChannelsList(channels: LiveData<List<MuNowNext>>) {
    val channelsList by channels.observeAsState(initial = emptyList())

There is a way to detect a swipe gesture?

This is shown in plugins

I use the following version

I've created a composable that has an higher zIndex than the other composables in the Box, so it's always visible but it doesn't receives click events. Is it a bug or my mistake?

Box {
    // here doesn't reiceive clicks, but it's visible because it has an higher zindex
    HomeToolbar(title = currentBox.name, modifier = Modifier.preferredHeight(56.dp))
    VerticalScroller {
        Column {
            Spacer(modifier = Modifier.preferredHeight(56.dp))
            PokemonList(pokemon = pokemonPreviews.value) { slot ->
                state.selectedPokemonIndex = slot
            }
            Spacer(modifier = Modifier.preferredHeight(16.dp))
        }
    }
    // here it's both visible and reiceives clicks
    HomeToolbar(title = currentBox.name, modifier = Modifier.preferredHeight(56.dp))
}

This code is put inside Box

val state = viewModel.currentState.collectAsState(viewModel.getInitialState())

Column(Modifier.fillMaxSize() + Modifier.drawBackground(color = Color.Blue)){
    AdapterList(modifier = Modifier.fillMaxSize(), data = state.value.dataList) {
        Text(
            modifier = Modifier.fillMaxWidth() + Modifier.preferredHeight(80.dp),
            text = it.title,
            color = Color.White
        )
    }
}

and gives me a runtime error while executing

LayoutNode@6292b16 children: 1 measureBlocks: MeasuringIntrinsicsMeasureBlocks@a9f8420{ measureBlock=androidx.ui.foundation.BoxKt$Box$1$1@0ed31d9 } is not measured, draw requested

When I remove AdapterList, it runs just fine EDIT: it's not working when data parameter is an empty list

When using

FilledTextField

in emulator, it is not possible to move cursor with arrow keys (<- & ->). Is this a known issue?

In case anyone else is having compilation issues, adding

'-XXLanguage:+NewInference'

does not work with google’s custom compiler

1.3.70-dev-withExperimentalGoogleExtensions-20200424

What do you think? When will compose be ready for production?

After a fling, any kind of scrollable layout (vertical/horizontal scroller & adapterlist) needs 2 clicks. The layout interprets the first click as the end of a fling and the second click as clicking on the list item. Is this a bug?

I have 2 questions about the TextField composable. How can I make the text cursor blink? How can I select the text? With a native EditText widget I can do it with a double tap/long press gesture on the text

hey will constraint layout and motion layout be ported to compose?

Created a new project tonight after updating to latest of everything (requisite half hour of looking at console updates that look like circa 1960) and it doesn’t run (asked for empty Compose Activity). The template still references

dev03

and it still has that stuff in it where kotlin version is a string in the base gradle file and you have to change that according to the app build file but then it is unhappy back in the other file. Seriously build is such a grease fire, it’s never going to be better. Probably one of the reasons Rust is gaining so much popularity… anyway time left for compose? 0

Hello, there is any way to create custom views with compose, so I can for example use them as a viewHolder view, I have the Composable fun but usually y just use inflate of the xml

And someone can tell me why this simple thing

Row {
    Text("Sample Text")
    Button("Click")
}

Is throwing IllegalStateException: No colors found!?

How to set the background color of Container ? Need help

DataTable

in compose is removed. Is there any alternative for that ?

Hi guys, is using Modifier object to something like,

Button(onClick = { state.counter++ }, modifier = Modifier.tag("testTag"))

but on my UiTests the method findByTag is not recognizing the button, any insights on this?

Hi does someone know how to use TextField with inputType of

Password

? This is showing the text still plain:

TextField(
    value = textState,
    modifier = Modifier.fillMaxWidth(),
    onValueChange = onChange,
    keyboardType = KeyboardType.Password
)

I guess this is version dev10?

This is one of my two screens, when first launched , as statusApp.lang has just been initialized the getListHeadlines is called, if I change the statusApp.fontSize, the headlines are redrawn but the headlines are not loaded which is what I want, but If I go to the next screen which is a detail screen, when I came back by pressing the back button and assigning the application screen to be again the headlines screen, I've got the elements reloaded as if stattusApp.lang would have changed.

In dev10 there is a problem with Box background color and

size

modifiers: backgroundColor not works in below code:

Box(backgroundColor = Color.Blue, modifier = Modifier.width(200.dp).height(100.dp))

works in below one:

Box(backgroundColor = Color.Blue, modifier = Modifier.size(200.dp))

I'm trying to write a music player style composable but I'm a bit stuck on how you would go about implementing the swipe motion where the current element on the screen is swiped off to the left while a new item appears from the right. Any ideas?

Is it possible to take a

CompositionReference

from a composable function, pass it through to a

FrameLayout

hosted inside the composition, and have that legacy view pass that reference through to a composable hosted inside itself? I.e. so that any ambients in effect where the legacy view is added to the composition get propagated to the leaf composable inside the legacy view. I’m doing the naïve thing right now of just having the legacy view call

setViewContent

instead of

setContent

, which takes a

CompositionReference

. However, the leaf composable doesn’t seem to be getting model updates, and throws an `IllegalStateException`: “Unsupported node type LayoutNode” if I try composing something like a

Text

. I’m sure all this infrastructure is full of holes right now, but is this something that’s ideally supposed to work?

setViewContent

has a TODO on it to remove, and the only other API that seems relevant here is

subcomposeInto

but that requires a

ComponentNode

which I haven’t tried to figure out how to get yet.

this is the error from the build: https://github.com/moonlitdoor/mld-amessage-android/runs/669546358#step:5:830
