Join Contact data with my table in Android

I have table with contacts identified by LOOKUP_KEY and I need JOIN it with system contact data to get real name and photo. Is possible do this? Or I must read contact data for every contact item CursorAdapter and开发者_如何学Python get required information about contact?

This question is related to: https://stackoverflow.com/questions/7222297/custom-contacts-view-join-or-combine-contactscontract-with-sqlite-table. But it's without reply.

Maybe a CursorJoiner would do the trick?

The only way to do that is going to be to read the data through the Content Provider, and put it in your own database. Afterwards you can perform JOIN queries with the data.
