Is there a way to detect a touch event on Android's Quadratic Bezier Curve?
I am fighting with path touch detection specifically with complicated Bezier Curves.
To detect whether touch has been performed on simple shape(Circle, Rectangle etc.) I am using the following method: RectF.contains(float x, float y). And this one works fine.
But the same method is not working for Curves (which is obvious since Curves should not have borders at all).
I suppose Android should have a way to detect path which is already drawn and displayed.
Have some workaround ideas but I will not be very happy if I use them.
Does someone has an idea how to solve this?
Thank you in advance.
