From android doc:

android:toXDelta

Float or percentage. Ending X offset. Expressed either: in pixels relative to the normal position (such as "5"), in percentage relative to the element width (such as "5%"), or in percentage relative to the parent width (such as "5%p").

Assuming your button width is 20% of it's parent width, you must specify your toXDelta as

50%p-(20%p/2) = 40%p

The problem with this solution is that you probably don't know the button width in terms of "% of it's parent width" (not sure since you didn't post the xml). So I would suggest to define your animation programmatically.
