question: public static int dragViewTo ( View v , int gravity , int toX , int toY ) { int [ ] xy = new int [ 2 ] ; getStartLocation ( v , gravity , xy ) ; int fromX = xy [ 0 ] ; int fromY = xy [ 1 ] ; int deltaX = fromX - toX ; int deltaY = fromY - toY ; int distance = ( int ) Math . sqrt ( deltaX * deltaX + deltaY * deltaY ) ; drag ( fromX , toX , fromY , toY , distance ) ; return distance ; }
target:  Simulate touching a view and dragging it to a specified location.
