我正在使用LinkedIn-j从linkedIn 获取基于组 ID 的组的信息，问题是我无法获取该组的成员总数。遵循我编写的代码。这里Group的对象没有任何字段可以给我这个信息。

import com.google.code.linkedinapi.client.LinkedInApiClient;
import com.google.code.linkedinapi.client.LinkedInApiClientFactory;
import com.google.code.linkedinapi.client.enumeration.GroupField;
import com.google.code.linkedinapi.schema.Group;
代码
LinkedInApiClientFactory factory = LinkedInApiClientFactory.newInstance(apiKey, apiSecret);
LinkedInApiClient client = factory.createLinkedInApiClient(oauthUserToken, oauthUserSecret);
Set<GroupField> fields = new HashSet<GroupField>();
fields.add(GroupField.CATEGORY);
fields.add(GroupField.CONTACT_EMAIL);
fields.add(GroupField.COUNTS_BY_CATEGORY);
fields.add(GroupField.DESCRIPTION);
fields.add(GroupField.ID);
fields.add(GroupField.IS_OPEN_TO_NON_MEMBERS);
fields.add(GroupField.LOCATION);
fields.add(GroupField.NAME);
fields.add(GroupField.POSTS);
fields.add(GroupField.RELATION_TO_VIEWER);
fields.add(GroupField.RELATION_TO_VIEWER_AVAILABLE_ACTIONS);
fields.add(GroupField.RELATION_TO_VIEWER_MEMBERSHIP_STATE);
fields.add(GroupField.SHORT_DESCRIPTION);
fields.add(GroupField.SITE_GROUP_URL);
fields.add(GroupField.WEBSITE_URL);
Group group= client.getGroupById(linkedInGroupId, fields);
