Android: Does anyone know how to finger paint on an ImageView?

If so how would you go about doing it? Sorry the question is so vague. I honestly don't know where start!

Hi Tae

Not sure about drawing to an imageview as far as I understand it an imageview is simply a placeholder for storing static images (I may be wrong).

The way I would approach it would be to create a new SurfaceView class and draw to the canvas based to the X,Y position of the touch on screen, a useful tutorial I have used in the past can be found below (There is a whole set of tutorials from this person/organisation) they are not as structured as what treehouse has to offer but do show alternative techniques.

Thanks. I followed the answer left by Raghunandan from stack overflow.

He sets the image to a linear layout. All i have have to do now is figure out how to save the image to the gallery along with the finger paint. Would you happen to know how?
