android - Animate image Button in circular motion -

i'm trying animate image button objectanimator move in circular motion

propertyvaluesholder tranx = propertyvaluesholder.offloat(view.translation_x, path); propertyvaluesholder trany = propertyvaluesholder.offloat(view.translation_y, path); objectanimator scaleanimation =             objectanimator.ofpropertyvaluesholder(scalebutton, pvhx, pvhy); scaleanimation.setrepeatcount(1); scaleanimation.setrepeatmode(valueanimator.reverse); 

i tried make path :

path path_x = new path(); path path_y = new path(); for(i = 0; < 2* math.py; += 0.1)   {     \\save path cos , sin        } 

but don't know method use inside loop if it's possible

i try other way create circular motion
