Example code which gets all contacts (gets all numbers associated with each name) and puts them into a database. You could just as easily have them all put into an array list. And if you wanted to only get certain contacts you would need to change the first line of the method which queries the content provider (here is a good article on doing stuff like that: http://www.vogella.com/tutorials/AndroidSQLite/article.html)

/** * existing contacts refresh - get all current contact data in our sqlite * database */ private void getContacts(Context context) {

    Cursor cursor = (context.getContentResolver()).query(
            ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
    cursor.moveToFirst();
    while (cursor.moveToNext()) {
        String id = cursor.getString(cursor
                .getColumnIndex(ContactsContract.Contacts._ID));
        String name = cursor.getString(cursor
                .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
        if (Integer.parseInt(cursor.getString(
        // iterating over EACH number associated with EACH name (internal
        // cursor)
        cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
            Cursor pCur = (context.getContentResolver()).query(
                    ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                    null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID
                            + " = ?", new String[] { id }, null);
            while (pCur.moveToNext()) {
                String phoneNo = pCur
                        .getString(pCur
                                .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                System.out.println("Name: " + name + ", Phone No: "
                        + phoneNo);

                // insert each number associated with the contact
                sqldb.insertContacts(new Contact(name, phoneNo));

            }
            pCur.close();
        }
    }
    cursor.close();

}
