ViewPager with Fragments is overkill?

I'm trying to implement a viewPager to display an array of strings (that contains three strings). I'm trying to look up a tutorial on how I would go about something like this, but it seems that I need to use a ViewPager with fragments. Isn't there a simple was to use a ViewPager without involving fragments?

Again, I'm following the developer docs: http://developer.android.com/training/animation/screen-slide.html

But, I don't necessarily want to make the entire screen move over. I'd only like for the bottom 1/3 of my screen to swipe. Can anyone confirm that this is possible to do without fragments? Or is there another view I should use (horizontal Scroll View)

EDIT:

So I was doing something right. I was trying to use a ViewPager and a pagerAdapter but my application crashes. Anything glaringly broken about my code?

  ViewPager mPager;
            setContentView(R.layout.activity_convo_detail);

            PagerAdapter mAdapter = new PagerAdapter() {

                @Override
                public boolean isViewFromObject(View arg0, Object arg1) {
                    // TODO Auto-generated method stub
                    return false;
                }

                @Override
                public int getCount() {
                    // TODO Auto-generated method stub
                    return 3;
                }
            };
            mPager = (ViewPager)findViewById(R.id.pager);
            mPager.setAdapter(mAdapter);

You don't need Fragments for ViewPager, Have a look : http://androidtrainningcenter.blogspot.com/2012/10/viewpager-example-in-android.html

And for your second Question, this is how you take 1/3 of space:

<?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<View
    android:layout_width="fill_parent"
    android:layout_height="0dp"
    android:layout_weight="2" />

<android.support.v4.view.ViewPager
    android:id="@+id/myfivepanelpager"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1" />

</LinearLayout>

Fragments aren't that heavy, or complicated. I don't think they are overkill for this.

However, you can use a PagerAdapter without using fragments.

A ViewPager can page plain old TextViews if that is what you want.

Basically, you don't have to use FragmentPagerAdapter. Your PagerAdapter can take an array of Strings and return just a view for each.
