i have 3000 contacts in my G1.And i need to display all of them in a app. I have used a thread to query them and set them to a view.(using Handler.)
But this is also not very fast.I need to display them all ASAP.... Now im considering about first displaying a part of the contacts ,when the user scoll the listView,then i add the other contacts. But now i have some problems. 1. How to query the first 200 contacts in the contacts. I have to use public final Cursor query (Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder). How to make up the selection? Top200? 2.Is custom cursor usefull here? What the cursor here can do ? And how to implements a Cursor?How to override all the abstract methods? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
