Hi Guys
recently i took the way to get into App Mobile whit Xamarin
Im new with this. so is why i need your support.

Well the case is this
In Visual Studio (whit Xamarin.Android) i would like to populate a Spinner with Key/value , like a combobox in VB.NEt/C#.Net
But is not easy to access to the items
i saw several examples , but all handle just the VALUE or one dimension.

i have this in my code:

C#

 protected override void OnCreate(Bundle bundle)
{
   base.OnCreate(bundle);

   // Set our view from the "main" layout resource
   SetContentView(Resource.Layout.Main);

   // SE CARGAN LOS CONTROLES DEL LAYOUT
        

   Button bRegistrar = FindViewById<Button>(Resource.Id.btnRegistrar);
   Spinner spinner = FindViewById<Spinner>(Resource.Id.spinner1);
   EditText sTarjeta = FindViewById<EditText>(Resource.Id.txtTarjeta);

   //SE LLENA EL SPINNER


  spinner.ItemSelected += new EventHandler<AdapterView.ItemSelectedEventArgs>(Spinner1_ItemSelected);
 
//spinner.

var adapter = ArrayAdapter.CreateFromResource(this, Resource.Array.listado_productos, Android.Resource.Layout.SimpleSpinnerItem);

            
    
    
   adapter.SetDropDownViewResource(Android.Resource.Layout.SimpleSpinnerDropDownItem);

    spinner.Adapter = adapter;

    //ASIGNAMOS EL EVENTO CLICK 
    bRegistrar.Click += BRegistrar_Click;




  }

private void BRegistrar_Click(object sender, EventArgs e)
  {
            Spinner spinner = FindViewById<Spinner>(Resource.Id.spinner1);
  }

from here... im lost.
i would like to get the key/value and assign to my variable

C#

clsParametros.SKU = spinner.GetThatItemSelectedkeyFromMySpinner();

I appreciate your support
Best regards.

i were already search in google and here, in codeproject.com but nothing

Hi guys i found a solution that Works for me. here is:

var dict = new Dictionary<int, string>();
        dict.Add(1, "Tarjeta1");
        dict.Add(2, "tarjeta2");

spinner.ItemSelected += new EventHandler<AdapterView.ItemSelectedEventArgs>(Spinner1_ItemSelected);    
ArrayAdapter adapter = new ArrayAdapter(this,Android.Resource.Layout.SimpleSpinnerItem,dict.Values.ToArray());
adapter.SetDropDownViewResource(Android.Resource.Layout.SimpleSpinnerDropDownItem);
spinner.Adapter = adapter;



private void btnButton(Object sender,EventArgs e)
{
int intValue = Convert.ToInt32(spinner.SelectedItem.ToString().Replace("Tarjeta", string.Empty).Trim());
   string strValue = intValue.ToString();
}

i hope this solution could help you.
Best regards.
