You are using a AccelerateInterpolator. The behavior you describe is how this class is made, as specified in the API. You may want to use the LinearInterpolator instead, if you want it to move at a constant rate. There are also other subclasses of Interpolator to chose from.

If you wish for the animation to be shorter or longer this is done with the setDuration method, in milliseconds, as you've set it to 1 minute in your example.
