Question

I create my page view from images on sd card, and it take some time (around 2 seconds). All operations I do in thread. When thread is finished, the isCreated flag set as true.

How do I prevent to show next page of ViewPager if isCreated is false?

I must override touch event?

Answer 1

you have some choices to do that:

• you can tell the user in a progress dialog “Please wait, loading images … blah”
• you can disable page scrolling by extends the ViewPager: overwrite the function “canScroll”
  and handle by your self if a user can scroll to the next/previous page
