DynamicActivity.cs

namespace FragmentsBase
{
    [Activity(Label = "FragmentsBase", MainLauncher = true, Icon = "@drawable/icon")]
    public class DynamicActivity : Activity
    {
        private int count = 0;

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

            SetContentView(Resource.Layout.DynamicLayout);

            FindViewById<Button>(Resource.Id.btnDynamic).Click += (sender, e) =>
            {
                DynamicFragment dynamic = new DynamicFragment();
                dynamic.DynamicName = $"動態產生 Fragment - {count}";
                count++;

                FragmentManager
                    .BeginTransaction()
                    .Add(Resource.Id.linearDynamic, dynamic)
                    .Commit();
            };
        }
    }

DynamicFragment.cs

namespace FragmentsBase
{
    public class DynamicFragment : Fragment
    {
        public override void OnCreate(Bundle savedInstanceState)
        {
            base.OnCreate(savedInstanceState);
        }

        public string DynamicName { get; set; }

        public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
        {
            View v = inflater.Inflate(Resource.Layout.DynamicFragmentLayout, null);
            v.FindViewById<TextView>(Resource.Id.txtDynamicCount).Text = this.DynamicName;
            return v;
        }
    }
