Have a look at the answer mentioned here . He's pretty much done the same thing as you, but if you look at the first comment on the highest rated answer, Cdsboy got it working by implementing OnDown and returning true. I'm not sure why that is needed, but it worked for me.
As a complement to @Abhinav 's answer (that btw helped me too), I'd like to say that I think overriding onDown() is needed because its default implementation in SimpleOnGestureListener is to return false. Being ACTION_DOWN the first one to reach the listener, it would make it discard the event, whatever it is.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
