Xamarin.Forms客户端第一版

作为TerminalMACS的一个子进程模块，目前完成第一版：读取展示手机基本信息、联系人信息、应用程序本地化。

功能简介
详细功能说明
关于TerminalMACS

1. 功能简介

1.1. 读取手机基本信息

主要使用Xamarin.Essentials库获取设备基本信息，Xam.Plugin.DeviceInfo插件获取App Id，其实该插件也能获取设备基本信息。

1.2. 读取手机联系人信息

Android和iOS工程具体实现联系人读取服务，使用到DependencyService获取服务功能。

1.3. 应用本地化

使用资源文件实现本地化，目前只做了中、英文。

2. 详细功能说明

2.1. 读取手机基本信息

Xamarin.Essentials库用于获取手机基本信息，比如手机厂商、型号、名称、类型、版本等；Xam.Plugin.DeviceInfo插件获取App Id，用于唯一标识不同手机，获取信息见下图：

代码结构如下图：

ClientInfoViewModel.cs

using Plugin.DeviceInfo;
using System;
using Xamarin.Essentials;

namespace TerminalMACS.Clients.App.ViewModels
{
    /// <summary>
    /// Client base information page ViewModel
    /// </summary>
    public class ClientInfoViewModel : BaseViewModel
    {
        /// <summary>
        /// Gets or sets the id of the application.
        /// </summary>
        public string AppId { get; set; } = CrossDeviceInfo.Current.GenerateAppId();
        /// <summary>
        /// Gets or sets the model of the device.
        /// </summary>
        public string Model { get; private set; } = DeviceInfo.Model;
        /// <summary>
        /// Gets or sets the manufacturer of the device.
        /// </summary>
        public string Manufacturer { get; private set; } = DeviceInfo.Manufacturer;
        /// <summary>
        /// Gets or sets the name of the device.
        /// </summary>
        public string Name { get; private set; } = DeviceInfo.Name;
        /// <summary>
        /// Gets or sets the version of the operating system.
        /// </summary>
        public string VersionString { get; private set; } = DeviceInfo.VersionString;
        /// <summary>
        /// Gets or sets the version of the operating system.
        /// </summary>
        public Version Version { get; private set; } = DeviceInfo.Version;
        /// <summary>
        /// Gets or sets the platform or operating system of the device.
        /// </summary>
        public DevicePlatform Platform { get; private set; } = DeviceInfo.Platform;
        /// <summary>
        /// Gets or sets the idiom of the device.
        /// </summary>
        public DeviceIdiom Idiom { get; private set; } = DeviceInfo.Idiom;
        /// <summary>
        /// Gets or sets the type of device the application is running on.
        /// </summary>
        public DeviceType DeviceType { get; private set; } = DeviceInfo.DeviceType;
    }
}

ClientInfoPage.xaml

        </StackLayout>
    </ContentPage.Content>
</ContentPage>

2.2. 读取手机联系人信息

Android和iOS工程具体实现联系人读取服务，使用到DependencyService获取服务功能，功能截图如下：

2.2.1. TerminalMACS.Clients.App

代码结构如下图：

2.2.1.1. 联系人实体类：Contacts.cs

目前只获取联系人名称、图片、电子邮件（可能多个）、电话号码（可能多个），更多可以扩展。

namespace TerminalMACS.Clients.App.Models
{
    /// <summary>
    /// Contact information entity.
    /// </summary>
    public class Contact
    {
        /// <summary>
        /// Gets or sets the name
        /// </summary>
        public string Name { get; set; }
        /// <summary>
        /// Gets or sets the image
        /// </summary>
        public string Image { get; set; }
        /// <summary>
        /// Gets or sets the emails
        /// </summary>
        public string[] Emails { get; set; }
        /// <summary>
        /// Gets or sets the phone numbers
        /// </summary>
        public string[] PhoneNumbers { get; set; }
    }
}

2.2.1.2. 联系人服务接口：IContactsService.cs

包括：

一个联系人获取请求接口：RetrieveContactsAsync
一个读取一条联系人结果通知事件：OnContactLoaded

该接口由具体平台(Android和iOS)实现。

using System;
using System.Collections.Generic;
using System.Threading;
using System.Threading.Tasks;
using TerminalMACS.Clients.App.Models;

namespace TerminalMACS.Clients.App.Services
{
    /// <summary>
    /// Read a contact record notification event parameter.
    /// </summary>
    public class ContactEventArgs:EventArgs
    {
        public Contact Contact { get; }
        public ContactEventArgs(Contact contact)
        {
            Contact = contact;
        }
    }

    /// <summary>
    /// Contact service interface, which is required for Android and iOS terminal specific 
    ///  contact acquisition service needs to implement this interface.
    /// </summary>
    public interface IContactsService
    {
        /// <summary>
        /// Read a contact record and notify the shared library through this event.
        /// </summary>
        event EventHandler<ContactEventArgs> OnContactLoaded;
        /// <summary>
        /// Loading or not
        /// </summary>
        bool IsLoading { get; }
        /// <summary>
        /// Try to get all contact information
        /// </summary>
        /// <param name="token"></param>
        /// <returns></returns>
        Task<IList<Contact>> RetrieveContactsAsync(CancellationToken? token = null);
    }
}

2.2.1.3. 联系人VM：ContactViewModel.cs

VM提供下面两个功能：

全部联系人加载。
联系人关键字查询。

using System;
using System.Collections;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Input;
using TerminalMACS.Clients.App.Models;
using TerminalMACS.Clients.App.Resx;
using TerminalMACS.Clients.App.Services;
using Xamarin.Forms;

namespace TerminalMACS.Clients.App.ViewModels
{
    /// <summary>
    /// Contact page ViewModel
    /// </summary>
    public class ContactViewModel : BaseViewModel
    {
        /// <summary>
        /// Contact service interface
        /// </summary>
        IContactsService _contactService;
        private string _SearchText;
        /// <summary>
        /// Gets or sets the search text of the contact list.
        /// </summary>
        public string SearchText
        {
            get { return _SearchText; }
            set
            {
                SetProperty(ref _SearchText, value);
            }
        }
        /// <summary>
        /// The search contact command.
        /// </summary>
        public ICommand RaiseSearchCommand { get; }
        /// <summary>
        /// The contact list.
        /// </summary>
        public ObservableCollection<Contact> Contacts { get; set; }
        private List<Contact> _FilteredContacts;
        /// <summary>
        /// Contact filter list.
        /// </summary>
        public List<Contact> FilteredContacts

        {
            get { return _FilteredContacts; }
            set
            {
                SetProperty(ref _FilteredContacts, value);
            }
        }
        public ContactViewModel()
        {
            _contactService = DependencyService.Get<IContactsService>();
            Contacts = new ObservableCollection<Contact>();
            Xamarin.Forms.BindingBase.EnableCollectionSynchronization(Contacts, null, ObservableCollectionCallback);
            _contactService.OnContactLoaded += OnContactLoaded;
            LoadContacts();
            RaiseSearchCommand = new Command(RaiseSearchHandle);
        }

        /// <summary>
        /// Filter contact list
        /// </summary>
        void RaiseSearchHandle()
        {
            if (string.IsNullOrEmpty(SearchText))
            {
                FilteredContacts = Contacts.ToList();
                return;
            }

            Func<Contact, bool> checkContact = (s) =>
            {
                if (!string.IsNullOrWhiteSpace(s.Name) && s.Name.ToLower().Contains(SearchText.ToLower()))
                {
                    return true;
                }
                else if (s.PhoneNumbers.Length > 0 && s.PhoneNumbers.ToList().Exists(cu => cu.ToString().Contains(SearchText)))
                {
                    return true;
                }
                return false;
            };
            FilteredContacts = Contacts.ToList().Where(checkContact).ToList();
        }

        /// <summary>
        /// BindingBase.EnableCollectionSynchronization
        ///     Enable cross thread updates for collections
        /// </summary>
        /// <param name="collection"></param>
        /// <param name="context"></param>
        /// <param name="accessMethod"></param>
        /// <param name="writeAccess"></param>
        void ObservableCollectionCallback(IEnumerable collection, object context, Action accessMethod, bool writeAccess)
        {
            // `lock` ensures that only one thread access the collection at a time
            lock (collection)
            {
                accessMethod?.Invoke();
            }
        }

        /// <summary>
        /// Received a event notification that a contact information was successfully read.
        /// </summary>
        /// <param name="sender"></param>

        private void OnContactLoaded(object sender, ContactEventArgs e)
        {
            Contacts.Add(e.Contact);
            RaiseSearchHandle();
        }

        /// <summary>
        /// Read contact information asynchronously
        /// </summary>
        /// <returns></returns>
        async Task LoadContacts()
        {
            try
            {
                await _contactService.RetrieveContactsAsync();
            }
            catch (TaskCanceledException)
            {
                Console.WriteLine(AppResource.TaskCancelled);
            }
        }
    }
}

2.2.1.4. 联系人展示页面：ContactPage.xaml

简单的布局，一个StackLayout布局容器竖直排列，一个SearchBar提供关键字搜索功能。

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"

            <SearchBar x:Name="filterText"
                        HeightRequest="40"
                        Text="{Binding SearchText}"
                       SearchCommand="{Binding RaiseSearchCommand}"/>
            <ListView   ItemsSource="{Binding FilteredContacts}"
                        HasUnevenRows="True">
                <ListView.ItemTemplate>
                    <DataTemplate>

                                        x:Name="image"
                                        Aspect="AspectFit"
                                        HeightRequest="60"/>
                                <StackLayout VerticalOptions="Center">

                    </DataTemplate>
                </ListView.ItemTemplate>
            </ListView>
        </StackLayout>
    </ContentPage.Content>
</ContentPage>

2.2.2. Android

代码结构如下图：

AndroidManifest.xml：写入读、写联系人权限请求。
ContactsService.cs：具体的联系人权限请求、数据读取操作。
MainActivity.cs：接收权限请求结果
MainApplicaion.cs：此类未添加任务关键代码，但必不可少，否则无法正确弹出权限请求窗口。
PermissionUtil.cs：权限请求结果判断

2.2.2.1. AndroidManifest.xml添加权限

只添加下面这一行即可：

<uses-permission android:name="android.permission.READ_CONTACTS" />

2.2.2.2. ContactsService.cs

Android联系人获取实现服务，实现IContactsService。注意命名空间上的特性代码，必须添加上这个特性后，在前面的联系人VM中才能使用DependencyService.Get()获取此服务实例，默认服务是单例的：

[assembly: Xamarin.Forms.Dependency(typeof(TerminalMACS.Clients.App.iOS.Services.ContactsService))]

                requestStop = true;
                taskCompletionSource.TrySetCanceled();
            });

            _isLoading = true;

            var hasPermission = await RequestPermissionAsync();
            if (hasPermission)
            {

                NSError error = null;

2.2.2.3. MainActivity.cs

代码简单，只在OnRequestPermissionsResult方法中接收权限请求结果：

// The contact service processes the result of the permission request.
ContactsService.OnRequestPermissionsResult(requestCode, permissions, grantResults);

2.2.3. iOS

代码结构如下图：

ContactsService.cs：具体的联系人权限请求、数据读取操作。
Info.plist：权限请求时描述文件

2.2.3.1. ContactsService.cs

iOS具体的联系人读取服务，实现IContactsService接口，原理同Android联系人服务类似，本人无调试环境，iOS此功能未测试。

2.2.3.2. Info.plist

2.3. 应用本地化

使用资源文件实现本地化，目前只做了中、英文。

资源文件如下：

指定默认区域性

要使资源文件可正常使用，应用程序必须指定 NeutralResourcesLanguage。在共享项目中，应自定义 AssemblyInfo.cs 文件以指定默认区域性。以下代码演示如何在 AssemblyInfo.cs 文件中将 NeutralResourcesLanguage 设置为 zh-CN (摘自官方文档：https://docs.microsoft.com/zh-cn/samples/xamarin/xamarin-forms-samples/usingresxlocalization/，后经测试，注释下面这段代码也能正常本地化)：

[assembly: NeutralResourcesLanguage("zh-CN")]

XAML中使用

引入资源文件命名空间

xmlns:resources="clr-namespace:TerminalMACS.Clients.App.Resx"

具体使用如

<Label Text="{x:Static resources:AppResource.ClientName_AboutPage}" FontAttributes="Bold"/>

3. 关于TerminalMACS及本客户端

3.1. TermainMACS

多终端资源管理与检测系统，包含多个子进程模块，目前只开发了Xamarin.Forms客户端，下一步开发服务端，使用 .NET 5 Web API开发，基于Abp vNext搭建。

3.2. Xamarin.Forms客户端

作为TerminalMACS系统的一个子进程模块，目前只开发了手机基本信息获取、联系人信息获取、本地化功能，后续开发服务端时，会配合添加通信功能，比如连接服务端验证、主动推送已获取资源等。
