Add Zoom in/out to ListView of Images?

I have a fragment which contains a ListView and multiple images (7-10) are displaced each time fragment is launched.

I tried using different libraries for the zooming purpose but the ListView won't show up as then I will have to replace ImageView with library's defined ImageView

How can I add zoom in/out for those images?

EDIT: I want to add zoom in/out to the ListView that contain different number of images on each load, as my question states.

EDIT 2: This is getview method of my Custom Adapter. How do I attach PhotoViewAttacher in it?

public View getView(int position, View convertView, ViewGroup parent) {
    View iv = convertView;
    ViewHolder holder = null;

    if (iv == null) {
        LayoutInflater inflater = ((Activity) context).getLayoutInflater();
        iv = inflater.inflate(layoutResourceId, parent, false);
        holder = new ViewHolder();

        holder.image = (ImageView) iv.findViewById(R.id.imagview);
        iv.setTag(holder);
    } else {
        holder = (ViewHolder) iv.getTag();
    }

    Picasso.with(context)
            .load((Integer) data.get(position))
            .resize(999, 720)
            .onlyScaleDown()
            .centerInside()
            .into(holder.image);

    return iv;
}

static class ViewHolder {
    ImageView image;
    PhotoViewAttacher mAttacher;
}

}

This is how I made it work

After importing PhotoView

In layout file (if you use layout):

<uk.co.senab.photoview.PhotoView
    android:id="@+id/your_photo_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    ... />

And in adapter

PhotoView photoView = (PhotoView) findViewById(R.id.your_photo_view);

Picasso.with(context)
    .load(file)
    ...
    .into(photoView);

Thanks everyone for your time.

Instead of taking simple ImageView in BaseAdapter's getView list item add TouchImageView
