Question

I get records from the system by quering a ContentResolver. I maintain the order of the items in the database. So I want to display the items in the order taken from my database.

How do I merge these two informations?

EDIT 1

I am looking after an alternative way now. As what I ideally want is:

• get order of contacts by a custom order held in my database (this involves joining CR with my DB cursor, and doing an order by, later seams it’s not possible with CursorJoiner)
• but there is more, if the join is not unique I want to sort by contact’s name as last measure

which is impossible using Cursor and Joiners, because of the missing feature of order bys, also I need to return a Cursor, as I will be using the in an ExpandableList

Also this translated to TSQL it would look like

select * from contactsdata 
left join category on contactsdata.catid=category.id
order by category.pos asc, contact.display_name asc

So I am looking now after an alternative.
I have in mind to load in a temporary DB table all data from CR, then do the query on the temporary table where I can join tables and do order bys? How does this sound to you?

Answer 1

Take a look at CursorJoiner.

If that doesn’t work, you can roll your own equivalent with a fair amount of pain, whiskey, or both.
