Why no gestures yet in Compose? should we manage gestures at the Activity level and just update the ViewModel?

I have just started using Compose. Now I would like to have a Camera(X) widget in a @Composable. Can not seem to find that component. How can I go about wrapping it up myself?

is there an easy way to display a gif/loading indicator/rotate a composable?

Is there're a way to make it working?

is there a way to provide

Android Context

in

Preview

? It is needed to take some resources like Vector drawables

Feedback:

color = (+MaterialTheme.colors()).primary

is way uglier than what it used to be:

color = +themeColor { primary }

is here something like RecyclerView?

so it's impossible to create a scrollable view?

Just a quick reminder. There is a small FAQ about compose here: https://github.com/Mishkun/jetpack-compose-faq @themishkun Created just for the community, if you want something to be added just open an issue or a pr!

I want to show a box appeared from bottom after onclick. Tried using

hi all, is there any straightforward way to show image with custom width and height? currently I am using

SimpleImage

wrapped inside a

Container

. code like this

Container(width = 62.dp, height = 42.dp) {
                SimpleImage(image = image)
            }

if I change a value of some prop inside

@Model

object, will it trigger rerender of a whole "tree"? I mean not only the composable that uses this object, right?

Is it possible that

imageFromResource

does not work in

repo

?

is it okay to use a new Kotlin Plugin 1.3.60 without eap?

Hi, I'm having issues using TextField. I can't use the cursor in order to move around the text and try to delete or edit it. I'm trying to do a simple calculator and this is what happens to me

Hello, what will be the equivalent of selectors in Compose? Will we be able to set a few attributes at once (like a style) instead of a selector per xml property?

We cannot able to use

try-catch

inside composable function. I am getting the below error

Try catch is not supported around composable function invocations.

Can there only be one

@Preview

function and does it need to be in the main activity?

Please explain me the difference between

+memo

,

+state

,

+model

and when to use which one ? I know all of this observing some value and try to recompose on value changes.

Hi, how can I add or remove components of my user interface at run time? tanks

Well, I mean as an example suppose you have a button and every time you press it you add a text or any other component to a certain container...

So there is no generic addview like concept in compose, but I think I got the idea many thanks (A list of parameters in a model, and a component which draws that list)

What’s the corresponding of:

setShadowLayer

in

androidx.ui.graphics.Paint

? Is there a way to draw shadow inside

Draw {}

composable?

I’m trying to draw a circle when the user tap on the screen. I have a

var inputPosition: Offset? by +state { null as Offset? }

I updated it inside the

PressGestureDetector

observer with:

inputPosition = Offset(position.x.value, position.y.value)

then I have a

@Composable

function that accept an

Offset?

as input and

Draw { canvas, _ -> canvas.drawCircle(pos, size.value, paint = paint) }

with that position. I’m getting the following error as soon as the user tap somewhere:

Have anyone a working example with compose and Room viewing a list in a VerticalScroller setting (or any other composable) which is imitating a recyclerview? Very interesting in how to detect where/when/how to add items the best way to the VerticalScroller when scrolling, and how to update data contents to the existing items in the list the best way ?

Hey, I see that Semantic public API documentation is still in the works (https://issuetracker.google.com/issues/138173117)? I am wondering how to set accessibility label onto a view (or if I got the terminology right - a node on the semantic tree?)

How do you folks draw Rectangle stroke border without fill? it looks like when i try to draw 3 rectangle borders one of them hide somehow

Trying to build any of the compose demos in the repo fails with a compiler error:

Caused by: java.lang.AssertionError: lastLineNumber shall be not negative, but is -1

	...

Not sure they currently don't compile and you're aware of this or my setup is wrong (I only followed the steps to clone the repo and ran

repo sync

). I also tried applying the kotlinc 1.3.61 patch but nothing changed. The command I ran was

./gradlew :ui:ui-material:integration-tests:ui-material-demos:installDebug
