Answered 2021-Jun-14 at 19:55If anyone stumbles over this question:
This is a known bug in the current Jetpack Compose build (1.0.0-beta08) which is supposed to be fixed with the next version.
As a workaround I was able to do it the other way round, creating the SurfaceView as well as a ComposableView in XML and adding my content to the ComposableView.
QUESTION
In my project I use JetPack Compose and the AndroidView to use an XML View.

Answered 2021-Jun-10 at 07:33You can use the update
block.
From the doc:
The
update
block can be run multiple times (on the UI thread as well) due to recomposition, and it is the right place to setView
properties depending on state. When state changes, the block will be reexecuted to set the new properties. Note the block will also be ran once right after thefactory
block completes
QUESTION
Most likely a newbie question, as i'm fairly new to Android dev - I am having troubles preserving the state of AndroidView in my @Composable on configuration change/navigation , as factory block is called (as expected) and my chart gets reinstantiated.
...ANSWER
Answered 2021-Jun-09 at 07:10I'd say your instincts were correct to move the chart instance into the view model, but, as you noted, context dependencies can become a hassle when they are required for objects other than views. To me, this becomes a question of dependency injection where the dependency is the context or, in a broader sense, the entire data chart. I'd be interested in knowing how you source your view model, but I'll assume it relies on an Android view model provider (via by viewModels()
or some sort of ViewModelProvider.Factory
).
An immediate solution to this issue is to convert the view model into a subclass of an AndroidViewModel
which provides reference to the application context via the view model's constructor. While it remains an anti-pattern and should used sparingly, the Android team has recognized certain use cases to be valid. I personally do not use the AndroidViewModel
because I believe it to be a crude solution to a problem which could otherwise be solved with refinements to the dependency graph. However, it's sanctioned by the official documentation, and this is only my personal opinion. From experience, I must say its use makes testing a view model quite a nightmare after-the-fact. If you are interested in a dependency injection library, I'd highly recommend the new Hilt
implementation which recently launched a stable 1.0.0
release just this past month.
With this aside, I'll now provide two possible solutions to your predicament: one which utilizes the AndroidViewModel
and another which does not. If your view model already has other dependencies outside of the context, the AndroidViewModel
solution won't save you much overhead as you'd likely already be instantiating a ViewModelProvider.Factory
at some point. These solutions will be considering the scope of an Android Fragment
but could easily be implemented in an Activity
or DialogFragment
as well with some tweaks to lifecycle hooks and whatnot.

QUESTION
I'm trying to implement simple map view inside scrollable column. The problem is that I can't scroll map vertically, as scroll event is captured by column and instead of map, whole column is scrolling. Is there any way to disable column scrolling on map element? I thought about using .nestedScroll()
modifier, but I can't find a way to make it work as desired.

Answered 2021-May-15 at 03:14Okay, so after I posted a question I tried to fix a problem again, and I found a working solution. However I'm not sure if it's the best way to achieve desired effect.

In Android using jetpack-compose, is there currently a way to display a text containing links in a @Composable Text
?
In legacy TextView,
we used Markwon with linkify plugin. Markwon creates a Spanned object that we can set into the TextView
's text.
Is there a way to proceed with the same with @Composable Text
? Or do we have to use a legacy TextView
embedded within a @Composable AndroidView
?
