Example 1
@Override
public void transformItem(View item, float position) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        ImageView avatarView = item.findViewById(R.id.list_item_passphrase_avatar);

        float translationZ = (float) Math.abs(SELECTED_TRANSLATION_Z - ((Math.pow(2, Math.abs(position)) - 1) * SELECTED_TRANSLATION_Z));
        avatarView.setTranslationZ(translationZ);
    }

    pivotX.setOn(item);
    pivotY.setOn(item);
    float closenessToCenter = 1f - Math.abs(position);
    float scale = minScale + maxMinDiff * closenessToCenter;
    item.setScaleX(scale);
    item.setScaleY(scale);
}
