如何在我的listview上打電話併發送郵件給某人？

Question

如何讓我的「OnEmailTapped」和「TlfnrTapped」不是靜態的？

我想做一個聯繫人列表中的姓名，電子郵件地址和電話號碼。所以我可以發送郵件和從我的列表視圖中打電話，但現在我只能打電話「12345678」，當我點擊一個電話號碼。我想使它成爲我打電話給我的電話號碼。與電子郵件一樣，我想發郵件給郵件地址，我點擊，而不是「Something@gmail.com」。有沒有辦法做到這一點？

我的聯繫方式：

using System.Collections.Generic; 

namespace App3 
{ 
public class Kontakter 
{ 
    public string Fuldenavn { get; set; } 
    public int Tlfnr { get; set; } 
    public string Email { get; set; } 
    public string Adresse { get; set; } 
    public string Billed { get; set; } 

    public List<Kontakter> GetKontakter() 
    { 
     List<Kontakter> kontakter = new List<Kontakter> 
    { 
     new Kontakter 
     { 
      Fuldenavn = "Anders (ANSE)", 
      Email = "Random@gmail.com", 
      Tlfnr = 12345678, 
     }, 
     new Kontakter 
     { 
      Fuldenavn = "Anja (ANBI)", 
      Email = "Random@hotmail.dk", 
      Tlfnr = 87654321, 
     }, 
     new Kontakter 
     { 
      Fuldenavn = "Benn (BMR)", 
      Email = "Random@hotmail.com", 
      Tlfnr = 12876534, 
     }, 
     new Kontakter 
     { 
      Fuldenavn = "Christian (CBE)", 
      Email = "Nothing@gmail.com", 
      Tlfnr = 18273645, 
     }, 
    }; 
     return kontakter; 
    } 
} 
} 

我Main.cs：

using Plugin.Messaging; 
using System; 
using System.Linq; 
using Xamarin.Forms; 

namespace App3 
{ 
public partial class MainPage : ContentPage 
{ 
    KontaktlisteView vm; 

    public MainPage() 
    { 
     InitializeComponent(); 
     vm = new KontaktlisteView(); 
     NameslistView.ItemsSource = vm.Kontakter; 
    } 

    private async void Kontakter_ItemTapped(object sender, ItemTappedEventArgs e) 
    { 
     ((ListView)sender).SelectedItem = null; 
     var Kontakter = e.Item as Kontakter; 

     await DisplayAlert("Kontakt", "\nName: " + Kontakter.Fuldenavn + "\nTelefon: " + Kontakter.Tlfnr + "\nEmail: " + Kontakter.Email, "Luk"); 
    } 

    private void MainSearchBar_SearchButtonPressed(object sender, EventArgs e) 
    { 
     var keyword = MainSearchBar.Text; 
     NameslistView.ItemsSource = vm.Kontakter.Where(obj => (obj.Fuldenavn.Contains(keyword) || obj.Tlfnr.ToString().Contains(keyword))); 
    } 
    private void MainSearchBar_TextChanged(object sender, TextChangedEventArgs e) 
    { 
     NameslistView.ItemsSource = vm.Kontakter.Where(obj => (obj.Fuldenavn.Contains(e.NewTextValue) || obj.Tlfnr.ToString().Contains(e.NewTextValue))); 
    } 

    private void OnEmailTapped(object sender, EventArgs e) 
    { 
     var emailMessenger = CrossMessaging.Current.EmailMessenger; 
     if (emailMessenger.CanSendEmail) 

      emailMessenger.SendEmail("Something@gmail.com"); 
    } 

    private void TlfnrTapped(object sender, EventArgs e) 
    { 
     var phoneDialer = CrossMessaging.Current.PhoneDialer;

如果您的綁定是正確的：

你可以得到的電子郵件地址挖掘和使用發送電子郵件：

emailMessenger.SendEmail(((Label)sender).Text); 

與電話號碼相同：

phoneDialer.MakePhoneCall(((Label)sender).Text);
