Using Coil, I want to in case I got no internet or whatever to simply fill my image with a simple androidx.compose.ui.graphics.Color.
Now, the .placeholder and .error function on Coil’s builder take in a Drawable, but I can’t figure out a way to get a hold of a Drawable in a simple way in Compose without going for xml drawables or something like that. Is there some API I’m missing?

there is a ColorDrawable

Right, I can use this and provide it a color defined in my xml resources. I guess this will do for now, but if I were to have a pure compose app and my theme was specified in code, are there no alternatives? 🤔

the compose Color has a toARGB function that you can pass to the constructor of the ColorDrawable

Aha! The int parameter which is annotated with @ColorInt means this ColorInt. Which reads Denotes that the annotated element represents a packed color int, AARRGGBB. If applied to an int array, every element in the array represents a color integer.
I thought it was referring to an xml source! Thanks a lot! This seems to be exactly what I was looking for.

IIRC Coil Compose has a placeholder parameter and you can use a ColorPainter.

Yeah I was still using rememberAsyncImagePainter as I was migrating from 1.x but you’re right I now tried this with the AsyncImage API which does take a Painter and that is super straightforward to use. I can just do ColorPainter(hedvigBlack). And I had a BitmapDrawable I was drawing before, but now I can just do BitmapPainter(myBitmapDrawable.bitmap.asImageBitmap()) and that works just fine too, thanks a lot!
