Hello Blake,
Thank you for your reply! I really appreciate it.
It looks like I didn't give enough details on my problem, so here is some
more information. As I already mentioned, we have the following inheritance
chain:
CustomListView <- ListView <- AbsListView <- AdapterView<T> <- ViewGroup <-
> ...
>
In my CustomListView class I've overrode protected void layoutChildren()
{...}. From that overridden method I'm calling super.layoutChildren().
After that there is a chain of internal calls within ListView class:
layoutChildren() -> fillFromTop() -> fillDown() -> makeAndAddView() ->
> obtainView()
>
obtainView() method is defined in AbsListView class and has a default
access modifier, thus I have NO ability to override it, as my
CustomListView class belongs to the different package. As a result, I can
only hide it, if I'll define obtainView() method with the same signature.
The thing is that my method SHOULD NOT be called from makeAndAddView()
method of the ListView class, obtainView() which belongs to the AbsListView
class should be utilized instead. But my tests show that obtainView() from
my CustomListView class is called, which is not correct. If I do not define
obtainView(), call chain looks as follows:
... -> makeAndAddView() -> obtainView() -> setupChild() ->
> attachViewToParent() OR addViewInLayout()
>
Both attachViewToParent() and addViewInLayout() are defined in the
ViewGroup class and have "protected" access modifiers, thus I SHOULD have
an ability to override them. BUT if I define this methods in my
CustomListView class, attachViewToParent() or addViewInLayout() of the
ViewGroup class are called instead, which is also incorrect.
Here are the sources of:

I would really appreciate the insight of such guru as you. Thank you again
for you time!
Have a nice day!
Alex
