Ok I must apologize for the out animation thing. It is actually a completely different thing. The setOutAnimation(...) is a method of ViewAnimator used by a couple of widgets like the ViewSwitcher for example.
Sorry about that.
Anyway lets go back to the point. Each View has a setAnimation(Animation) and startAnimation(Animation) methods.
Take a look here
for examples of how to define, load and use animations.
If you still have problems with that stuff post me a PM and we'll work them out.
Edit: You also might wanna have a look at LayoutAnimationController
