Android add Stroke to Drawable on Runtime

Question

I found this function. How can I now add a Stroke to my Drawable?
There is nothing like setStroke(...)

Answer 1

Try creating a paint variable with the your intended color/stroke width/ (also set style=stroke) and then use it in the onDraw method:

onDraw(Shape shape, Canvas canvas, Paint paint)

In this way, the stroke will be added when you draw. It will not be attached to your Drawable.
