如果用户加入房间后，想要了解此房间的成员构成，可以调用 queryRoomMemberList 接口，传入参数 roomID，config，然后通过 ZIMRoomMemberQueriedCallback 中的 onRoomMemberQueried 回调接口，返回房间内成员列表。

参数	参数类型	是否必填	描述
nextFlag	string	是	分页查询的标识位。首次查询时，请将此字段设为空字符串。若回调的 "nextFlag" 字段不是空字符串，说明还未查询完所有用户，此时需要将其设置为当前位置，以继续下一页的查询。
count	int	是	查询一次，可获取的成员数量。注意事项：分页获取消息以降低开销，建议单次获取 100 个成员以内。
