I have a listview with 200 items. I use a custom view for each row. There is a code that takes some time to calculate, and because of this the list hangs out on scrolling and loads in slow (2-3sec).
I have subclassed SimpleCursorAdapter, and using Filterable and SectionIndexer.
I have in mind to show initially the name of the record, and put in a thread the calculation, and will show up later when it's done.
How do I push back some work, and later update the listview to include the calculated data? This should show up on fly without user interaction.
