Rotate Animation is showing some delay in every rotation -

please suggest me answer here code.

    rotate animation rotate = new rotate animation(0, 360,    animation.relative_to_self, 0.5f, animation.relative_to_self, 0.5f);      rotate.setinterpolator(new linearinterpolator());     rotate.setrepeatmode(animation.infinite);     rotate.computedurationhint();     rotate.setrepeatcount(animation.infinite);     rotate.setduration(durationsecs);     rotate.setstartoffset(-1);     rotate.setfillafter(true);     miv_bloodpumpspeed.startanimation(rotate); 

private rotateanimation setrotatedanimation(context context, float pivotx,             float pivoty, int duration) {         rotateanimation rotated = new rotateanimation(0, 360,                 animation.relative_to_self, pivotx, animation.relative_to_self,                 pivoty);         rotated.setinterpolator(context, android.r.anim.cycle_interpolator);         rotated.setrepeatcount(animation.infinite);         rotated.setrepeatmode(animation.restart);         rotated.setduration(duration);         return rotated;     }
