Gestures and color drawing

Question

I am detecting gestures on one of my activities - I am using it to navigate through photos. Every time I am doing a gesture, yellow line is being drawn on the screen. Is there any way to set GestureColor as transparent?

Answer 1

if you write the color in the form of "#aarrggbb", then 'aa' represent the transparency. Thus the color #00000000 is completely transparent.

Cheers,
