ViewPager onPageScrolled event not called

The following code scrolls the 4 pages just fine. My problem is that the `onPageScrolled` event does not get triggered when the pages are scrolled. This occurs whether or not I use the `myPager.SetOffsccreenPageLimit(4)` command. After reading the docs, it is my understanding that when I have `implements ViewPager.OnPageChangeListener` included in the `MyPagerAdapter` class that the event should be triggered. What am I doing wrong? Thanks, Gary Blakely ``` public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); MyPagerAdapter adapter = new MyPagerAdapter(); ViewPager myPager = (ViewPager) findViewById(R.id.mysevenpanelpager); myPager.setAdapter(adapter); myPager.setCurrentItem(0); myPager.setOffscreenPageLimit(4); } private class MyPagerAdapter extends PagerAdapter implements ViewPager.OnPageChangeListener { public int getCount() { return 4; } public Object instantiateItem(View collection, int position) { LayoutInflater inflater = (LayoutInflater) collection.getContext() .getSystemService(Context.LAYOUT_INFLATER_SERVICE); int resId = 0; switch (position) { case 0: resId = R.layout.left; break; case 1: resId = R.layout.gps; break; case 2: resId = R.layout.map; break; case 3: resId = R.layout.right; break; } View view = inflater.inflate(resId, null); ((ViewPager) collection).addView(view, 0); return view; } @Override public void destroyItem(View arg0, int arg1, Object arg2) { ((ViewPager) arg0).removeView((View) arg2); } @Override public void onPageScrollStateChanged(int arg0) { int myint = 9; myint = myint * 2; } @Override public void onPageScrolled(int arg0, float arg1, int arg2) { int myint = 9; myint = myint * 2; } @Override public void onPageSelected(int arg0) { int myint = 9; myint = myint * 2; } } ```
