How to Scroll ViewPager?

问题:

I am new to Android.How to use ViewPager.scrollBy(int x,int y)? ViewPager.scrollBy(int x,int y) is not updating View

new Handler().post(new Runnable() {                      @Override                     public void run() {                         // TODO Auto-generated method stub                          mainPager.scrollBy(10,0);                      }                 }); 

even this is not updating View. please tell me what is the difference between scrollTo(int x,int y) and scrollBy(int x,int y);

From what I understand scrollTo() and scrollBy() are not applicable to ViewPager; they're just methods defined by View that do not apply to ViewPager.

If you're trying to move to a specific page, use setCurrentItem(int item, boolean smoothScroll).
