                      public void finish() {
                          super.finish();
                          // override transitions to skip the standard window animations
                          overridePendingTransition(0, 0);
                      }

#ImageView transition with ViewPager click view to see detail in other layout...

Feature:

1.original view: just like normal imageview but with zoom effect
2.detail view:
① single click back to pre layout with shrink effect
② double click to zoom effect(*2.5)
③ more gesture see details code
3.if u have more than one imageview can display with ViewPager
random click original imageview,and scroll ViewPager to any position,
than u press back key,or single click detail,u will see original view's
position is the same as ViewPager‘s current position.

And also ViewPager has rebound effect when edge of ViewPager is available..
