I'm new to Jetpack Compose. I created an app and as a preview I get only the views, in my case a text view.
How can I preview a screen and not an individual element?
I want something like that:
I am using Android Studio 2020.3.1 Canary 8.
Use the annotation #Preview(showSystemUi = true).
More info about the preview annotations here.

Hi, I want to migrate my apps to android jetpack compose and create custom card like this. But, when I try to using my trick on xml (using same elevation value) to create shadow around the card, I can't generate the same result.
How can this be achieved using jetpack compose?
I wanted to convert the XML code to Jetpack Compose code using the Recompose plugin (https://github.com/pocmo/recompose).
The following error occurs when trying to install a plug-in: Error
My version of Android Studio: About Android Studio
Please help.
It looks like recompose has not been updated to run as a plugin in the later Android Studio versions. You can still run recompose from the command line. My experience was that it was limited and could not handle a large amount of my layout XML, as I have a good bit of logic around animations, layer-lists, themed vector assets, dynamically updated texts and drawables, and conditional visibility.
To try with the command line, you can use something like this
./gradlew recompose-cli:run --args="C:\Users\Admin\AndroidStudioProjects\SmarterGarage\sglibrary\src\main\res\layout\activity_main.xml"
any idea to make android studio Jetpack compose auto refresh like Hot reload in Flutter it's annoying! Is there Auto-refresh in Jetpack Compose viewer?
Right now, compose does not support Hot reloads.
But Literals values can be updated directly.
Some supported types.
Int
String
Color
Dp
Boolean
You can view constant literals that trigger real-time updates without the compilation step by enabling these highlighted values.
Reference
When Android Studio Electric Eel becomes stable, Live Edit is enabled by default that acts as Hot Reload. Right now its still on preview.
I have several composables with a preview in my activity. they take a long time to render, and I only need to check one composable. How do I disable the composable preview in Android Jetpack Compose?
You could use the group attribute in the Preview.
Something like:
#Composable
#Preview(group="Test")
fun test1(){ }
Then in the Preview panel you can select the preview group:
In this way you can select the preview to be displayed.
I use Compose with AS Arctic Fox v2020.3.1. When I update the code, the preview does not render in real-time. AS show the message "The preview is out of date" and I must click "Build & Refresh". I'd like it to render UI in real-time, similar to XML Design.
How do it?
Thanks in advance.
AFAIK you can't. You're able to edit string values and certain others, such as padding dp's but when adding or removing elements, you have to rebuild to view the updated layout.
