Bob,
The error is caused by addHeaderView wrapping your ListView adapter.
public void addHeaderView (View v)
Since: API Level 1
Add a fixed view to appear at the top of the list. If addHeaderView is
called more than once, the views will appear in the order they were
added. Views added using this call can take focus if they want.
NOTE: Call this before calling setAdapter. *This is so ListView can
wrap the supplied cursor with one that will also account for header
and footer views.*
So if you call getAdapter right after calling setAdapter (and in case
there was a prior addHeaderView), you will not get back the same object,
you will get a HeaderViewListAdapter. It's actually in your logcat.
Your adapter implements Filterable, but
android.widget.HeaderViewListAdapter does not. Hence the class cast
exception.
I can think of two ways to fix this:
- Do not use addHeaderView, instead add the header layout into the
ListView's parent, positioned right above.
- Might also work: keep a reference to your original adapter object, the
one that implements Filterable, and use that object reference for
casting to Filterable.

OK, that eliminates that.
((Filterable) adapter).getFilter().filter(s);
Does your adapter extend Filterable?
