I think you need two animations with different speeds. After the first has finished, the second gets played.

Animation anim1 = new AlphaAnimation (1, 0.5F);
anim1.setDuration (600); //The slow part.
//set other things for anim1

Animation anim2 = new AlphaAnimation (0.5F, 0);
anim2.setDuration (200); //The fast part.
//set other things for anim2

You can use Interpolators to have a variable speed during animation. Example can be found here.
