ViewPager does not redraw content, remains/turns blank

Question

We\'re suffering from a very strange issue with ViewPager here. We embed lists on each ViewPager page, and trigger notifyDataSetChanged both on the list adapter and the view

Answer 1

For me the problem was coming back to the activity after the app process was killed. I am using a custom view pager adapter modified from the Android sources.The view pager is embedded directly in the activity.

Calling viewPager.setCurrentItem(position, true);

(with animation) after setting the data and notifyDataSetChanged() seems to work, but if the parameter is set to false it doesn't and the fragment is blank. This is an edge case which may be of help to someone.
