I need to show 6 items that the user can scroll through horizontally.  Of these 6 items, the first 2 should be showing first.  Then, as the user scrolls, the first 2 scroll left and the next 2 scroll into view.  For the next scroll, only the 5th item scrolls into view.  And then the 6th item on the next scroll.  

The items also have titles.  The first 2 items have a single title, the next 2 have a single title, and each of 5th and 6th have their own titles as well.  So, something like this:

    screen1title
item1          item2


— now the user scrolls left and the next screen snaps into place:

    screen2title
item3          item4


— scroll again, and we see:
...

I tried using a RecyclerView with a horizontal LinearLayoutManager and a LinearSnapHelper which snaps the items into place.  I kept only the items in the RecyclerView and the titles in a separate textview that I can scroll manually in a RecyclerView.OnScrollListener.  The problem I have is getting the RecyclerView to show 2 items on the first 2 screen and only 1 item on each of the next 2 screens.  How can I solve this problem?

I’ve tried setting the width for the first 4 items at runtime like this:
   view.getLayoutParams().width = mDisplayMetrics.widthPixels / 2;

This works but now the LinearSnapHelper is still snapping 1 item into the middle of the screen.  For example, it snaps item2 into the middle and you see half of item1 on the left and half of item3 on the right.
