如何從Xamarin Android中的單選按鈕獲取值？

Question

我需要獲取單選按鈕的文本。在代碼中有4個radiogroups和13個單選按鈕，如果有人選擇了按鈕3，我需要將這個文本發送給一個變量，然後發送一封電子郵件給帶有CC的投票人+他的經理。

     string toast = string.Format("Colaborador selecionado: {0}", spinner.GetItemAtPosition(e.Position)); 
     Toast.MakeText(this, toast, ToastLength.Long).Show(); 
    } 



    } 
} 

我應該使用rdbIntegridade.getCheckedRadioButtonId（）; ？

我也想知道如何創建一個按鈕來發送一個電子郵件傳遞單選按鈕值+一個評論，將在一個EditText字段。

Answer 1

我需要獲取單選按鈕的文本。

您可以訂閱的Click事件的每RadioButton，例如像這樣：

RadioButton rbtn = FindViewById<RadioButton>(Resource.Id.rbtn); 
rbtn.Click += Rbtn_Click; 

在Click事件：

private void Rbtn_Click(object sender, EventArgs e) 
{ 
    var radiobtn = sender as RadioButton; 
    var text = radiobtn.Text; 
} 

所以，你可以訂閱的RadioButton所有Click事件與像Rbtn_Click這樣的處理程序。

我也想知道如何創建一個按鈕來發送一個電子郵件傳遞的radiobuttons值+一個評論，將在一個EditText字段。

對於發送電子郵件部分，您可以參考官方文檔Send an Email。

//send to 
email.PutExtra (Android.Content.Intent.ExtraEmail, 
new string[]{"person1@xamarin.com", "person2@xamrin.com"}); 
//cc to 
email.PutExtra (Android.Content.Intent.ExtraCc, 
new string[]{"person3@xamarin.com"}); 
//subject 
email.PutExtra (Android.Content.Intent.ExtraSubject, "Hello Email"); 
//content 
email.PutExtra (Android.Content.Intent.ExtraText, 
"Hello from Xamarin.Android");
