Answer 1

It does not exist by default,

But can be made by extending a SurfaceView (creating your own 'widget') If you handle the touch events to draw a line on the surface with the onDraw method, then save the drawing to a Bitmap image.

You can then add your custom widget to your layout to show your signature widget.

Real autograph recognition for authenticating logins and such is however a completely different and way more advanced topic.
