Question

所以我正在尝试学习如何使用C＃为移动应用程序编写代码。我一直在研究最初用于Windows Forms的教程，我一直在尝试将代码格式化为Android版本，以便我可以在手机上测试它。我目前遇到的问题是从微调器中获取值并在以后使用它。我想做的是从旋转器中获取“武器”，然后使用该武器对怪物造成伤害。对于Windows窗体，原始代码看起来像这样：

 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));
                }
            }
        }

Windows窗体中的cboWeapons是一个组合框。我在代码中保留了相同的命名，但它是一个微调器。

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();
}

我的武器类是在一个引擎项目中定义的，我遇到了一些问题，我可以在后面的代码中像Windows窗体那样引用currentWeapon。

Answer 1

这是我用来获取所选项目的内容：

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

它适用于我的字符串微调列表。

Android：将变量设置为微调器项以供以后使用
