как оптимизировать вложенный цикл в lda, код модели темы в r

Хорошо, я исправляю элемент «click». Я получаю правильные значения. Но скажите, как использовать LongClick? и получить значения для этого элемента в новой форме? Это новый код для BaseAdapter:

using System;
using System.Collections.Generic;

using Android.App;
using Android.Content;
using Android.Views;
using Android.Widget;
using NovaAndroid.Model;

namespace NovaAndroid.Adapters
{
[Activity(Label = "ContactListBaseAdapter")]
public partial class ContactListBaseAdapter : BaseAdapter<the_SetSubjModel>
{

    IList<the_SetSubjModel> contactListArrayList;
    private LayoutInflater mInflater;
    private Context activity;
    the_SetSubjModel model = new the_SetSubjModel();
    Dictionary<int, the_SetSubjModel> items;
    private Context mContext;
    private int mRowLayout;


    public ContactListBaseAdapter(Context context, IList<the_SetSubjModel> results, 
int rowLayout) 
    {
        this.activity = context;
        this.items = items;
        context = context;
        mContext = context;
        mRowLayout = rowLayout;
        contactListArrayList = results;
        mInflater = 
 (LayoutInflater)activity.GetSystemService(Context.LayoutInflaterService);
    }

    public override int Count
    {
        get { return contactListArrayList.Count; }
    }

    public override long GetItemId(int position)
    {
        return position;
    }

    public override the_SetSubjModel this[int position]
    {
        get { return items[position]; }
    }



    public override Java.Lang.Object GetItem(int position)
    {
        return position;
    }



    public override View GetView(int position, View convertView, ViewGroup parent)
    {

        View view = convertView;
        if(view==null)
        {
           // view = LayoutInflater.From(mContext).Inflate(mRowLayout, parent, 
  false);
            //view = Layou   // view = 
  context.tInflater.From(mContext).Inflate(mRowLayout, parent, false);
            //view = 
  LayoutInflater.From(mContext).Inflate(Resource.Layout.list_row_contact_list, null);
        }
        //ImageView btnDelete;
        //ContactsViewHolder holder = null;

            view = mInflater.Inflate(Resource.Layout.list_row_contact_list, null);
            //holder = new ContactsViewHolder();
            //// Show item in listView
            //holder.txtacSubject = view.FindViewById<TextView> 
 (Resource.Id.lr_fullName);
            //holder.txtacAddress = view.FindViewById<TextView> 
 (Resource.Id.lr_address);
            //holder.txtEmail = view.FindViewById<TextView>(Resource.Id.lr_email);
            //holder.txtPib = view.FindViewById<TextView>(Resource.Id.lr_pib);



            //view.Tag = holder;





        TextView txtacSubject = view.FindViewById<TextView>(Resource.Id.lr_fullName);
        txtacSubject.Text = contactListArrayList[position].acSubject;

        TextView txtacAddress = view.FindViewById<TextView>(Resource.Id.lr_address);
        txtacAddress.Text = contactListArrayList[position].acAddress;

        TextView txtEmail = view.FindViewById<TextView>(Resource.Id.lr_email);
        txtEmail.Text = contactListArrayList[position].acPost;

        TextView txtPib = view.FindViewById<TextView>(Resource.Id.lr_pib);
        txtPib.Text = contactListArrayList[position].acCode;


        if (position % 2 == 0)
        {
            view.SetBackgroundResource(Resource.Drawable.list_selector);
        }
        else
        {
            view.SetBackgroundResource(Resource.Drawable.list_selector_alternate);
        }

        view.Click += delegate
          {
              Toast.MakeText(mContext, contactListArrayList[position].acSubject, 
        ToastLength.Short).Show();
          };

        view.LongClick += delegate
          {

          };


        return view;


    }



    public IList<the_SetSubjModel> GetAllData()
    {
        return contactListArrayList;
    }

    public class ContactsViewHolder : Java.Lang.Object
    {
        public TextView txtacSubject { get; set; }
        public TextView txtacAddress { get; set; }
        public TextView txtEmail { get; set; }
        public TextView txtPib { get; set; }            
        public TextView txtacName2 { get; set; }
        public TextView txtacPhone { get; set; }
        public TextView txtacRegNo { get; set; }
        public TextView txtanRebate { get; set; }


    }

    class ContactListBaseAdapterViewHolder : Java.Lang.Object
    {
        //Your adapter views to re-use
        //public TextView Title { get; set; }
    }
}
}

Это моя новая форма, где я должен показывать данные для элемента «Long Long»
