Android - Custom Interpolator Class Reference In Xml

I have written my own custom interpolator class .

@Override
    public float getInterpolation(float t) {

        return t*t*t;

    }

I am doing Fragment slide in and slide out animation .There I want to give the reference of this interpolator class in the xml.

But In the xml I am only able to add android provided interpolators.

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://ift.tt/nIICcg">

    <translate
            android:fromXDelta="594"
            android:startOffset="0"
            android:interpolator="@android:anim/accelerate_decelerate_interpolator"
            android:toXDelta="0" 
            android:fillAfter="true"
            android:duration="400"/>



</set>

So basically I wanted to know how to give reference of Custom Interpolator class in Xml.
