Android StartActivityForResult and Finish (with video)

Question

I have a MainActivity class with an Add Element button and a list and AddItemActivity class with a text box and a Save button. The user must click "Add Item", go to the AddItemActivity screen, enter the item, click "Save", and then return to the updated MainActivity screen.

(BTW, I am using MonoDroid, but I do not think it is necessary for a specific problem with MonoDroid).

My element "Add element" click (by main activity):

    private void addItemButton_Click(object sender, EventArgs e)
    {
        var intent = new Intent();
        intent.SetClassName(this, "monoApp.AddItemClassName");
        StartActivityForResult(intent, 0);
    }

My Save event click (when adding activity to an element):

    private void saveButton_Click(object sender, EventArgs e)
    {
        var itemname = FindViewById<EditText>(Resource.id.itemName);

        _repo.SaveItem(new Item() {Name = itemname.Text.ToString()});

        Toast.MakeText(this, "You saved: " + itemname.Text, ToastLength.Short).Show();

        var intent = new Intent();
        SetResult(Result.Ok, intent);
        Finish();
    }

And again in the main activity:

    protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
    {
        base.OnActivityResult(requestCode, resultCode, data);

        RefreshTheList();
    }
