Set Animation Speed?

I have 3 different image view and the animation runs very slow. Is there a way to speed up the animation?

mFlipper.setInAnimation(AnimationUtils.loadAnimation(this,android.R.anim.fade_in));
mFlipper.setOutAnimation(AnimationUtils.loadAnimation(this,android.R.anim.fade_out));

I would like to change have the image change every 1 sec. Is this possible? Thanks.
