this need exactly

here suggestions , depend on needs

  1. you should create own class extends imageview or whichever widget using hold image , override ondraw , there draw pixel wherever want.

  2. if needs on more permanent pixel location. should create bitmap image , draw pixel , after assign bitmap whichever widget want.

if need move marker go first suggestion, , in opposite case second

hope helps , enjoy work.
