如何通過點擊標籤在Xamarin.Forms中打電話？

你好我有一個應用程序，我正在Xamarin.Forms中獲取來自Web服務的聯繫信息，然後在標籤中顯示該信息，但是我想使標籤列出電話號碼以便在點擊時撥打電話。我如何去做這件事？如何通過點擊標籤在Xamarin.Forms中打電話？

標籤是沒有互動，所以你需要使用一個手勢，使其應對水龍頭：

var tapGestureRecognizer = new TapGestureRecognizer(); 
tapGestureRecognizer.Tapped += (s, e) => { 
    // handle the tap 
}; 

// attache the gesture to your label 
number.GestureRecognizers.Add(tapGestureRecognizer);

來打個電話，你可以使用內置的Device.OpenUri()方法與「電話：1234567890" 的說法，或者使用Messaging插件：

var phoneDialer = CrossMessaging.Current.PhoneDialer; 
if (phoneDialer.CanMakePhoneCall) 
    phoneDialer.MakePhoneCall("+272193343499");

賈森感謝您的快速回復唯一的問題是，數字的變化取決於它是如何「phoneDialer.MakePhoneCall（」+ 272193343499「）」;「將無法使用它必須調用Number.text中的內容我該如何去做這件事？ – Phoneswapshop

如果你想讓它撥打標籤中的值，那麼只需使用Number.Text代替硬編碼的字符串 – Jason

工作正常！非常感謝！ – Phoneswapshop

快速片段，快使用手機的撥號程序從Xamarin形式：

var CallUsLabel = new Label { Text = "Tap or click here to call" }; 
    CallUsLabel.GestureRecognizers.Add(new TapGestureRecognizer { Command = new Command(() => { 
      Device.OpenUri(new Uri("tel:038773729")); 
     }) });
