reference site : http://grishma102.blogspot.kr/2013/10/drag-and-drop-functionality-to-move.html
but, activity's zoom in, zoom out don't function when move objects on finger touch, objects zoom out , screen out.
please me..
try overriding ondrag() listener instead of ontouch()
view.setondraglistener(new view.ondraglistener() { @override public boolean ondrag(view view, dragevent dragevent) { return true; } });
