Add CheckBox in ListView WP RT

How do I add a CheckBox in my ListView in MainPage.xaml.cs? This is my code where I populate my Listview

foreach (char parameter in App.dados)
            {
                dados += parameter.ToString();
                espaco = dados.IndexOf(" \n ");
                if (espaco >= 0)
                {
                    ListViewItem lvItem = new ListViewItem();
                    lvItem.Holding += ListViewItem_Holding;
                    lvItem.FontSize = 25;                        
                    lvItem.Width = 500;
                    lvItem.Content = dados;
                    listView.Items.Add(lvItem);
                    dados = "";
                }
            }
