Bug : getting a gap on the header area in case the scrollView's LinearLayout child removes views

[AndroidDeveloperLB]

Scenario:
make the app have the FadingActionBar , with parralex effect and an imageView in the header.
The bottom area (the content) should be a vertical LinearLayout and a lot of views, enough to be able to scroll.
At runtime, scroll a bit down and then cause the LinearLayout to remove some of its views.

The bug:
the imageView on the top gets an empty gap below itself, which doesn't contain anything.

How do I solve this?

For the above scenario, you could try the following option:

1. Get the removed view height
2. Get the current ObservableScrollview scrollY position
3. Deduct the scrollY value with the removed view height and get the newscrollY value
4. call the ObservableScrollview.scrollTo(0,newscrollY)

Then the gap wont appear

i have this issue using a listview if i reinitialize the adapter. any ideas how i would go about sorting this issue for a listview that doesn't have the observablescrollview property?

[doodlleus]

actually I can see a way forward. by making the base class' onNewScroll() method public, i can call it using the necessary offset.

+1 for the problem. M trying with the logic but not clear about the offset i need to use. any help @doodlleus ? did u make it work?
