Android：將一個變量設置爲一個微調項目供以後使用

Question

因此，我正在嘗試在一個教程上學習如何在C＃中爲移動應用程序進行編碼。我一直在研究最初針對Windows Forms的教程，並且一直試圖將代碼格式化爲android版本，以便我可以在手機上進行測試。 我目前遇到的問題是從微調器中獲取一個值並稍後使用它。我想要做的就是從旋轉器上拿一把「武器」，然後用那個武器對怪物造成傷害。 原始代碼看起來像這樣爲Windows窗體：

private void btnUseWeapon_Click(object sender, EventArgs e) 
     { 
      // Get the currently selected weapon from the cboWeapons ComboBox 
      Weapon currentWeapon = (Weapon)cboWeapons.SelectedItem; 

      // Determine the amount of damage to do to the monster 
      int damageToMonster = RandomNumberGenerator.NumberBetween(currentWeapon.MinimumDamage, currentWeapon.MaximumDamage); 

      // Apply the damage to the monster's CurrentHitPoints 
      _currentMonster.CurrentHitPoints -= damageToMonster; 

      // Display message 
      rtbMessages.Text += "You hit the " + _currentMonster.Name + " for " + damageToMonster.ToString() + " points." + Environment.NewLine; 

      // Check if the monster is dead 
      if(_currentMonster.CurrentHitPoints <= 0) 
      { 
       // Monster is dead 
       rtbMessages.Text += Environment.NewLine; 
       rtbMessages.Text += "You defeated the " + _currentMonster.Name + Environment.NewLine; 

       // Give player experience points for killing the monster 
       _player.ExperiencePoints += _currentMonster.RewardExperiencePoints; 
       rtbMessages.Text += "You receive " + _currentMonster.RewardExperiencePoints.ToString() + " experience points" + Environment.NewLine; 

       // Give player gold for killing the monster 
       _player.Gold += _currentMonster.RewardGold; 
       rtbMessages.Text += "You receive " + _currentMonster.RewardGold.ToString() + " gold" + Environment.NewLine; 

       // Get random loot items from the monster 
       List<InventoryItem> lootedItems = new List<InventoryItem>(); 

       // Add items to the lootedItems list, comparing a random number to the drop percentage 
       foreach(LootItem lootItem in _currentMonster.LootTable) 
       { 
        if(RandomNumberGenerator.NumberBetween(1, 100) <= lootItem.DropPercentage) 
        { 
         lootedItems.Add(new InventoryItem(lootItem.Details, 1)); 
        } 
       } 

       // If no items were randomly selected, then add the default loot item(s). 
       if(lootedItems.Count == 0) 
       { 
        foreach(LootItem lootItem in _currentMonster.LootTable) 
        { 
         if(lootItem.IsDefaultItem) 
         { 
          lootedItems.Add(new InventoryItem(lootItem.Details, 1)); 
         } 
        } 
       } 

       // Add the looted items to the player's inventory 
       foreach(InventoryItem inventoryItem in lootedItems) 
       { 
        _player.AddItemToInventory(inventoryItem.Details); 

        if(inventoryItem.Quantity == 1) 
        { 
         rtbMessages.Text += "You loot " + inventoryItem.Quantity.ToString() + " " + inventoryItem.Details.Name +Environment.NewLine; 
        } 
        else 
        { 
         rtbMessages.Text += "You loot " + inventoryItem.Quantity.ToString() + " " + inventoryItem.Details.NamePlural + Environment.NewLine; 
        } 
       } 

       // Refresh player information and inventory controls 
       lblHitPoints.Text = _player.CurrentHitPoints.ToString(); 
       lblGold.Text = _player.Gold.ToString(); 
       lblExperience.Text = _player.ExperiencePoints.ToString(); 
       lblLevel.Text = _player.Level.ToString(); 

       UpdateInventoryListInUI(); 
       UpdateWeaponListInUI(); 
       UpdatePotionListInUI(); 

       // Add a blank line to the messages box, just for appearance. 
       rtbMessages.Text += Environment.NewLine; 

       // Move player to current location (to heal player and create a new monster to fight) 
       MoveTo(_player.CurrentLocation); 
      } 
      else 
      { 
       // Monster is still alive 

       // Determine the amount of damage the monster does to the player 
       int damageToPlayer = RandomNumberGenerator.NumberBetween(0, _currentMonster.MaximumDamage); 

       // Display message 
       rtbMessages.Text += "The " + _currentMonster.Name + " did " + damageToPlayer.ToString() + " points of damage." + Environment.NewLine; 

       // Subtract damage from player 
       _player.CurrentHitPoints -= damageToPlayer; 

       // Refresh player data in UI 
       lblHitPoints.Text = _player.CurrentHitPoints.ToString(); 

       if(_player.CurrentHitPoints <= 0) 
       { 
        // Display message 
        rtbMessages.Text += "The " + _currentMonster.Name + " killed you." + Environment.NewLine; 

        // Move player to "Home" 
        MoveTo(World.LocationByID(World.LOCATION_ID_HOME)); 
       } 
      } 
     } 

的cboWeapons Windows窗體是一個組合框。 我在我的代碼中保留了相同的命名，但它是一個微調。

Spinner cboWeapons = (Spinner)FindViewById(Resource.Id.cboWeapons); 
// Create an ArrayAdapter using the string array and a default spinner layout 
ArrayAdapter<Weapon> adapter = new ArrayAdapter<Weapon>(this, 
Android.Resource.Layout.SimpleSpinnerItem, weapons); 
adapter.SetDropDownViewResource(Android.Resource.Layout.SimpleSpinnerDropDownItem); 
cboWeapons.Adapter = adapter; 

public void onItemSelected(AdapterView<?> parent, View view, int position, long id) 
{ 
// On selecting a spinner item 
object CurrentWeapon =parent.GetItemAtPosition(position); 
Weapon currentWeapon = new CurrentWeapon(); 
} 

我的武器級轎車在發動機項目定義，我有做currentWeapon東西，我可以像Windows窗體確實後來的代碼中引用的問題。

Answer 1

這是我用它來獲得選擇的項目：

var TheSelectedIten = string.Format("{0}", SimpleSpinner.GetItemAtPosition(SimpleSpinner.SelectedItemPosition)); 

它爲我串的微調列表。
