I've got a ViewPager made by ImageViews implemented like this:

```
@Override
    public Object instantiateItem(View collection, int position) {
        ImageView iv = new ImageView(ctx);
        if (pageList.size() > position)
            iv.setImageBitmap(pageList.get(position));
        else
            iv.setImageResource(R.drawable.loading);

        iv.setOnTouchListener(this);
        ((ViewPager) collection).addView(iv, 0);
        System.out.println("POS: " + position);
        return iv;
    }

```

Any chance i can have that ImageView zoomable by double tap (and swipe the image) or pinch zoomable?
