What I want to do is draw a line that will follow my finger and move that line. I've created a custom view, and I have an onTouchEvent() that works.
I can draw a static line in the onDraw() method without much trouble.

use touchdown to store the first x1,y1, and then touchup to store x2,y2 and also on touchup invalidate() after you get the coordinates – JRowan Oct 12 '13 at 16:09
