android scaleanimation with custom Interpolator make easing effect

Question

I created ScaleAnimation and added my custom Interpolator.i try to recieve slide animaton right to left.this is a my source

 public class HesitateInterpolator implements Interpolator {
    public HesitateInterpolator() {}
    public float getInterpolation(float x) {

        return (float) (6 * Math.pow(x, 2) - 8 * Math.pow(x, 3) + 3 * Math.pow(x, 4));
    }
}

and this is a my animation source code:

 ScaleAnimation anim = new ScaleAnimation(0.0f, 1.0f, 1.0f, 1.0f, Animation.RELATIVE_TO_SELF,1.0f, Animation.RELATIVE_TO_SELF, 0.5f);
        anim.setDuration(100);
        anim.setInterpolator(new HesitateInterpolator());

i searched about Interpolator and also i found some links for example this

Do you really need a custom `Interpolator`? Material design pages present some standard ones (`AccelerateInterpolator` and `DecelerateInterpolator`). — Bartek Lipinski, Oct 05 '15 at 09:24
yes yes i want custom Interpolator. can you show me some examples ? @BartoszLipinski Lipinski — donoachua, Oct 05 '15 at 20:06
But WHY do you need a custom one? you can use one of the standard ones (e.g. `AccelerateInterpolator` and `DecelerateInterpolator`), they will probably fit your needs. — Bartek Lipinski, Oct 05 '15 at 20:20
I have LeftToRight Animation and i want to use animation same as material design. I mean,in material design animation has different spead,i mean,firs time spead is slow and then faster please see my links@BartoszLipinski Lipinski — donoachua, Oct 05 '15 at 20:24
