My suggestion would be -- generally don't do this. Animations during activity transitions are done by the window manager, on their windows. Prior to 2.0, these were turned off by default (though could be turned on by the user), and as of 2.0 they are turned on by default.
Trying to create your own animation in your own view, is (a) inconsistent with the standard Android UI, (b) not following the user's preference, and (c) going to interact extremely poorly with the normal activity animations when they are shown. There can of course be exceptions to this, for example perhaps the next activity is translucent in which case there is no animation on it normally and an animation within the previous activity's UI would not conflict with it. But that kind of thing is going to be very, very rare. Also as of 2.0 there are some new APIs to customize the actual activity animation for a particular transition... though again, I would highly recommend not doing this except under extremely special circumstances, since it makes your application inconsistent with whatever standard animations the user sees. And one other thought on animations: the animations that are shown during UI transitions have a very strong impact on the user's perception on how they are moving through the UI and where they are. Replacing the standard ones with gratuitous custom ones has a very high chance of harming the user experience, because it tells the user "something really importantly different happened here;" if what happened was actually a normal navigation (such as between two activities), then this can end up being very misleading and confusing.
