问题 I am working on ViewPager but a surprising problem comes up. The ViewPager when scrolled to get next page, it got stuck if I take my finger off from screen , but normally the view should bounce back or next view should come up which it does not.

Here is preview of what I am trying to say - (different color boxes are different screenshot combined in

问题 I'm writing my first fragment-based app and running into some heavy problems which i couldn't solve with the API or Stackoverflow. I am using a viewPager to swipe between two lists.

The problem is: FragmentList A returns the debug message for FragmentList B FragmentList B returns no debug message ... // The main class public class
