Xamarin : Alert Dialogs

Xamarin : Alert Dialog

Let's create Xamarin alert dialog with ok and cancel button.

• First create the layout dialog.xaml

  x
  <?xml version = "1.0" encoding = "utf-8"?> 
  <LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android" 
     android:orientation = "vertical" 
     android:layout_width = "fill_parent" 
     android:background = "#d3d3d3" 
     android:layout_height = "fill_parent"> 
     <Button 
        android:id="@+id/MyButton" 
        android:layout_width = "fill_parent" 
        android:layout_height = "wrap_content" 
        android:text = "confirm" 
        android:textColor = "@android:color/background_dark" 
        android:background = "@android:color/holo_green_dark" /> 
  </LinearLayout>
  

   

• Open DialogActivity.cs and create it's functionality

  x
  protected override void OnCreate(Bundle bundle) { 
     base.OnCreate(bundle); 
     SetContentView(Resource.Layout.Main); 
     Button button = FindViewById<Button>(Resource.Id.MyButton); 
     button.Click += delegate { 
        AlertDialog.Builder alertDiag = new AlertDialog.Builder(this); 
        alertDiag.SetTitle("ok or cancel"); 
        alertDiag.SetMessage("want to cancel"); 
        alertDiag.SetPositiveButton("ok", (senderAlert, args) => { 
           Toast.MakeText(this, "ok", ToastLength.Short).Show();
        }); 
        alertDiag.SetNegativeButton("Cancel", (senderAlert, args) => { 
           alertDiag.Dispose(); 
        }); 
        Dialog diag = alertDiag.Create(); 
        diag.Show(); 
     }; 
  }
