I ended up getting this solved as follows.
I basically just created a new adapter every time the data set needed
to change and replaced the adapter for the view pager.
InternalContentAdapter adapter = new InternalContentAdapter();
adapter.loadContents(someContentList);
this.internalContentPager.setAdapter(adapter);
This is my pager adapter. I'm using internal web views as my views.
This probably isn't the best explanation (or implementation) but it
works for me. Let me know if you have any questions.
/**
* Pager Adapter to handle internal web view pages. This drives
the swipe navigation for the internal content.

private class InternalContentAdapter extends PagerAdapter{
/** The content objects represented by this pager. */
private List<Content> contents;
/** The starting position. */
private int startPosition = 0;
/** The starting content id. */
private String startContentId = null;
/** Flag for whether or not to set the starting position. */
private boolean setPrimary = true;
@Override
public int getCount() {
// Send back the contents size
return this.contents.size();
}

@Override
public Object instantiateItem(ViewGroup container, int
position) {
// Load up the page
InternalWebView page = new InternalWebView(ctx, repo);
page.loadInternalPage(this.contents.get(position).getContentId());
page.setInternalWebViewListener(getListener());
//this.parentActivity.registerForContextMenu(page);
// Need to add this without the position
container.addView(page);
return page;

view) {
((ViewPager) container).removeView((InternalWebView)
view);
}
