运用ContactModel API来读取电话本信息

在Ubuntu的手机设计中，我们可以利用ContactModel API接口来读取我们的电话本信息．我们可以通过如下的API接口：

availableManagers 

来获取我们所有的电话本的manager．也就是有多少个电话本．通过设置：

manager 

来选择不同的电话本来读取信息．所有的电话本信息，我们可以在如下的API中读取：

contacts : list<Contact>

每个 Contact包含一个电话本每个项的所有的信息：

address : Address
addresses : list<Address>
anniversary : Anniversary
avatar : Avatar
birthday : Birthday
contactDetails : list<ContactDetail>
contactId : int
displayLabel : DisplayLabel
email : EmailAddress
emails : list<EmailAddress>
extendedDetail : ExtendedDetail
extendedDetails : list<ExtendedDetail>
family : Family
favorite : Favorite
gender : Gender
geolocation : GeoLocation
globalPresence : GlobalPresence
guid : Guid
hobby : Hobby
manager : string
modified : bool
name : Name
nickname : Nickname
note : Note
onlineAccount : OnlineAccount
organization : Organization
organizations : list<Organization>
phoneNumber : PhoneNumber
phoneNumbers : list<PhoneNumber>
presence : Presence
ringtone : Ringtone
syncTarget : SyncTarget
tag : Tag
timestamp : Timestamp
type : enumeration
url : Url
urls : list<Url>
version : Version

我们可以根据我们所需要的信息来显示．

当我们显示信息的时候，我们可以通过SortOrder来排序我们的电话本中的项．

  ContactModel {
        id: mymodel
        sortOrders: [
            SortOrder {
                id: sortOrder

                detail: ContactDetail.Name
                field: Name.FirstName
                direction: Qt.DescendingOrder
            }
        ]
　　...
  }

我们也可以通过filter来过滤我们所需要的项，比如：

        filter: DetailFilter {
            id: favouritesFilter

            detail: ContactDetail.Favorite
            field: Favorite.Favorite
            value: "Yang"
            matchFlags: DetailFilter.MatchExactly
        }

这个filter将显示所有的Favorite的电话本，而如下的filter将显示lastName中有＂Yang＂的电话本：

        filter: DetailFilter {
            id: nameFilter

            detail: ContactDetail.Name
            field: Name.LastName
            value: "Yang"
            matchFlags: DetailFilter.MatchExactly
        }

我们的一个简单的例程如下:

Main.qml

import QtQuick 2.4
import Ubuntu.Components 1.3
import QtContacts 5.0
import Ubuntu.Components.ListItems 1.0 as ListItem

MainView {
    // objectName for functional testing purposes (autopilot-qt5)
    objectName: "mainView"

    // Note! applicationName needs to match the "name" field of the click manifest
    applicationName: "contactmodel.liu-xiao-guo"

    width: units.gu(100)
    height: units.gu(75)


    ContactModel {
        id: mymodel
        sortOrders: [
            SortOrder {
                id: sortOrder

                detail: ContactDetail.Name
                field: Name.FirstName
                direction: Qt.DescendingOrder
            }
        ]

        fetchHint: FetchHint {
            detailTypesHint: [ContactDetail.Avatar,
                ContactDetail.Name,
                ContactDetail.PhoneNumber]
        }

//        filter: DetailFilter {
//            id: favouritesFilter

//            detail: ContactDetail.Favorite
//            field: Favorite.Favorite
//            value: "Yang"
//            matchFlags: DetailFilter.MatchExactly
//        }

        filter: DetailFilter {
            id: nameFilter

            detail: ContactDetail.Name
            field: Name.LastName
            value: "Yang"
            matchFlags: DetailFilter.MatchExactly
        }
    }

    Component {
