Draw bitmap outside the canvas boundaries

Question

I wish to draw bitmap icon on top of view like this:

I tried answer for similar question, but it doesn't work for me

override fun onDraw(canvas: Canvas) {
    super.onDraw(canvas)
    if (checkIconBitmap != null) {
        canvas.drawBitmap(checkIconBitmap,
                canvas.width - centerPosition.toFloat(),
                canvas.height - centerPosition.toFloat(),
                paint)
    }
}

Is this Xamarin or something? looks like a cross between iOS and android — Notsileous, Jan 30 '18 at 16:01

Probably because you are using Swift code? Override fun is not actual android code. It should look more like this:

@Override
protected void onDraw(canvas Canvas) {
super.onDraw(canvas)
if (checkIconBitmap != null) {
    canvas.drawBitmap(checkIconBitmap,
            canvas.width - centerPosition.toFloat(),
            canvas.height - centerPosition.toFloat(),
            paint)
    }
}

No, it's a kotlin. – Mishel Jan 30 '18 at 17:55
You need to provide that sort of info, there are now multiple platforms and they all have different syntax. – Notsileous Jan 30 '18 at 17:57
syntax does not matter, it is a question of canvas flexibility. – Mishel Feb 01 '18 at 10:36
If you want people to understand your code, yeah it does matter. – Notsileous Feb 01 '18 at 16:04
