How to add an item in sorted order in listview?

Postby jclova » Thu Nov 12, 2009 4:03 pm

I know if you're to display entire list in sorted order,
simply do 'ORDER BY' to sort database cursor.

However, I have a thread to insert a new item.
How can I add so that it doesn't add at the bottom but add in sorted order?

Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1.  
  2.  
  3. list.clear();
  4.  
  5. for (int i = 0; i < c.getCount(); i++)
  6.  
  7. {
  8.  
  9.      list.add(item);
  10.  
  11. }
  12.  
  13. myAdapter.setListItems(list)
  14.  
  15. this.setListAdapter(myAdapter);
Parsed in 0.010 seconds, using GeSHi 1.0.8.4


Isn't this inefficient?

is there a way to:

But to add in sorted order?

Thanks in advance~!
