Hi Peli
here i attach my code, to be added , i have ressolved the issue of double
image by getting rawX() value of the event , and setting my absolute layout
according to that.
but here i get a unique problem, whenever i click the button and try to drag
it, the mouse tip comes to a certain pixels above from the topleft corner of
the button,like a offset distance,if you run the code on the emulator u wil
find this problem.
