now, trying make make whole activity touched enabled. please view game.java see how did it. problem is, not reacting kind of touch event! there nothing wrong code onswiptouchlistener.java because have used touch events of setting listener image view. there must problem trying make whole activity touch enabled. saying "whole activity touch enabled" mean is, need swipe across whole screen instead of adding listener imageview.

what have done wrong here? please help!
