在gData hackstack＆hellip找到GroupContactEntry针;？

ContactGroupEntry

    // contactsService has been properly initialized...
    // hunting for the groupNameId corrisponding to the plaintext groupName

    while (list.size() < totalResults) {
        Query q = new Query(url);
        q.setStartIndex(f.getStartIndex() + f.getItemsPerPage());
        q.setMaxResults(200);
        f = this.contactsService.query(q, ContactGroupFeed.class);
        list.addAll(f.getEntries());        
    }

    for(ContactGroupEntry g : list) {
        if (groupName.compareTo(g.getPlainTextContent()) == 0) {
            groupNameId = g.getId();
            break;
        }
    }
    // return groupNameId
