How to obtain all details of a contact in Android
Given a contact id, I can obtain various contact details (like name, phone, email-id, etc) by making different queries for a each of these fields.
But is 开发者_运维技巧there a method to obtain all the details associated with this contact id by making a single query?
Had to change a bit of the tutorial on Content Providers since it referenced deprecated classes, this might help.
import android.provider.ContactsContract.Contacts;
import android.database.Cursor;
// Form an array specifying which columns to return, you can add more.
String[] projection = new String[] {
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone
ContactsContract.CommonDataKinds.Email
};
Uri contacts = ContactsContract.Contacts.CONTENT_LOOKUP_URI;
// id of the Contact to return.
long id = 3;
// Make the query.
Cursor managedCursor = managedQuery(contacts,
projection, // Which columns to return
null, // Which rows to return (all rows)
// Selection arguments (with a given ID)
ContactsContract.Contacts._ID = "id",
// Put the results in ascending order by name
ContactsContract.Contacts.DISPLAY_NAME + " ASC");
