title: how to use keypress events in mvvmcross for android?
body: <p>i have some problems trying to get the keyboard typing event ...so what i want is 
  execute the command "GoContratoCommand" when the user press the "enter" button on the keyboard</p>
  
  <p>this is part of  my ViewModel:</p>
  
  <pre><code>using System;
  using System.Collections.Generic;
  using Cirrious.MvvmCross.ViewModels;
  using MultiPage.Core.Services;
   namespace MultiPage.Core.ViewModels
   {
   public class FirstViewModel
      : MvxViewModel
       {
  
  
  
      private Cirrious.MvvmCross.ViewModels.MvxCommand _goContratoCommand;
      public System.Windows.Input.ICommand GoContratoCommand
      {
          get{
  
                  _goContratoCommand = _goContratoCommand ?? new Cirrious.MvvmCross.ViewModels.MvxCommand(inv_prod_pareja);
                       return _goContratoCommand;
                 }
  
          }
  
  
      }
      }
  </code></pre>
  
  <p>and this is my activity(or view as you want to call it) on the path: views/FirstView.cs</p>
  
  <pre><code>using Android.App;
  using Android.OS;
  using Android.Widget;
  using Cirrious.MvvmCross.Droid.Views;
  
  namespace MultiPage.Droid.Views
  {
      [Activity(Label = "View for FirstViewModel")]
      public class FirstView : MvxActivity
      {
          protected override void OnCreate(Bundle bundle)
          {
              base.OnCreate(bundle);
              //SetContentView(Resource.Layout.FirstView);
              SetContentView(Resource.Layout.screen01);
              var contrato= FindViewById&lt;EditText&gt;(Resource.Id.txtMembershipNumber);
              contrato.EditorAction += EventHandlerContrato;
          }
          public void EventHandlerContrato(object MyObject,EditText.EditorActionEventArgs e){
              e.Handled = false;
              if (e.ActionId == Android.Views.InputMethods.ImeAction.ImeNull ||
                  e.ActionId == Android.Views.InputMethods.ImeAction.Next ||
                  e.ActionId == Android.Views.InputMethods.ImeAction.Unspecified ||
                  e.ActionId == Android.Views.InputMethods.ImeAction.None ||
                  e.ActionId == Android.Views.InputMethods.ImeAction.Send ||
                  e.ActionId == Android.Views.InputMethods.ImeAction.Go)
              {
                  var algo=((Core.ViewModels.FirstViewModel)this.DataContext).GoContratoCommand;
                  e.Handled = true;
  
              }
          }
