    @Override

    }

        imageView.setImageDrawable(mImages.get(position));
        ((ViewPager) container).addView(imageView, 0);
        return imageView;
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        ImageView imageView = (ImageView) object;
        ((ViewPager) container).removeView(imageView);
    }

    @Override

        return POSITION_NONE;
    }
