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

I ran into this and had very similar issues. I even asked it on stack overflow.

For me, in the parent of the parent of my view someone subclassed LinearLayout and overrode requestLayout() without calling super.requestLayout(). This prevented onMeasure and onLayout from being called on my ViewPager (although hierarchyviewer manually calls these). Without being measured they'll show up as blank in ViewPager.

So check your containing views. Make sure they subclass from View and don't blindly override requestLayout or anything similar.
