 Hi I'm trying to clean up some code and now I'm determined to get this
seemless ListView updating working...

I want my ListView to be updated when I call notifyDataSetChanged()
but nothing happens... I'm also passing the autoRequery flag to true
when creating my CursorAdapter.

Cursor c = FavoritesHandler.getCategoryFavorites(getSQLiteInstance(),

Any help is greatly appreciated!

That sounds wrong to me. Unless you have a really, really complex UI.

If you have a local database you should be able to engineer your app to
fetch data using queries as required for display, rather than
loading monolithic arrays.

Whether or not this is possible, this sounds awful from a user-experience

2. Disable all input on ListView

I have a layout that looks like this


When i press the image view i toggle the visibility of the last
LinearLayout holding the AutoCompleteTextViews.
I wonder if there is a solution to this problem.

When the LinearLayout holding the AutoCompleteTextViews gets visible
and drawn over the list I can still scroll the listview, click the
items in it and scroll up/down on the scroll wheel on the nexus one
makes the component selection behave strange.

I can solve some of the issues by setting setFocusable(false) and
setting the setOnItemClickListener(null) on the listView. But the user
can still scroll the "background panel" which is the list view. Please
help me out
