Android contacts Display Name and Phone Number(s) in single database query?

Question

I\'m trying to obtain a list of contacts from the native database with their Display Name and Phone Number (any or all). There are many methods for obtaining this informatio

Answer 1

Phone numbers are stored in their own table and need to be queried separately. To query the phone number table use the URI stored in the SDK variable ContactsContract.CommonDataKinds.Phone.CONTENT_URI. Use a WHERE conditional to get the phone numbers for the specified contact.

private String displayName(Uri contactUri) {
        HashSet detail = ContactDetail.getInstance().getContactArray();
        Log.d("ITEM", contactUri.toString());
        String[] projection = new String[]{ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER};
        Cursor queryCursor = getActivity().getContentResolver()
                .query(contactUri, null, null, null, null);
        queryCursor.moveToFirst();
        String name = queryCursor.getString(queryCursor.getColumnIndex("display_name"));
        String id = queryCursor.getString(
                queryCursor.getColumnIndex(ContactsContract.Contacts._ID));

        if (Integer.parseInt(queryCursor.getString(queryCursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
            Cursor pCur = getActivity().getContentResolver().query(
                    ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                    null,
                    ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
                    new String[]{id}, null);
            while (pCur.moveToNext()) {
                String number = pCur.getString(pCur.getColumnIndex("data1"));
                Log.d("Contact Name: ", number);
            }
            pCur.close();
        }


        return name;
    }

Perform a second query against the Android contacts SQLite database. The phone numbers are queried against the URI stored in ContactsContract.CommonDataKinds.Phone.CONTENT_URI. The contact ID is stored in the phone table as ContactsContract.CommonDataKinds.Phone.CONTACT_ID and the WHERE clause is used to limit the data returned.
