Android – horizontal scrolling of multiple viewable items

This one has surprisingly easy answer, I’m not even sure why it wasn’t posted right away. All that I needed to do to get the exact effect was to override PagerAdapter#getPageWidth method. By default it returns 1 but if you set it to 0.5 you will get 2 pages, 0.33 will give you 3, etc. Depending on width of the separator between pager items you may have to slightly decrease the value.

See the following snippet:

    @Override
    public float getPageWidth(final int position) {
        // this will have 3 pages in a single view
        return 0.32f;
    }
