Draw a shape in android studio

[dal]

Hi, so all I want to do is draw a rectangle or square in android studio and fill it with a colour use RGB values without having to spend what feels like 2 years reading up on how to do it. I've tried looking at
THIS but can't get any of the code snippets to work ( even with trying to import stuff )
So if anyone could show me I would really appreciate it, thanks in advance.

The simplest way to do it right now, in a brand new project, would be to use Jetpack Compose to draw a box, clip it to the Rectangle Shape and set the color to your RGB color like so:

val color = Color(0, 255, 0, 255)
Box(modifier = Modifier.size(100.dp).clip(RectangleShape).background(color))

Thats the bare minimum and you'll see a preview like this:

Reason I said brand new project is because if you're wanting to add a rectangle to a view in an existing project then your project might use XML views opposed to Jetpack Compose since it's relatively new. I'd recommend looking at this stackoverflow post which creates a drawable, then you create a view in your XML which background uses the drawable.

Can I draw rectangle in XML?

I wonder if I can draw rectangle in XML. I know how to draw using drawRect method programmatically.
