c# - monodroid - 默认新的未修改模板项目无法在 android 模拟器中运行

Question

我最近使用 Visual Studio 2010 Professional 安装了 monodroid 和附加组件。它似乎在新项目中有部分编码，而且它似乎不是一个有效的示例代码。它通过使用菜单中的“构建解决方案”编译得很好，但它在 android 模拟器中不起作用。我期待一个只有文件结构的空白项目，但它似乎给了我一个不完整的示例项目。这在 visual studio 2010 pro 和 monodevelop 中都会发生。

是否存在只有文件结构的空白项目？如果可以，我在哪里可以访问它们？ 如果这应该是一个空白模板，那么为什么会有一些看起来像按钮计数器的代码。

谢谢 乔恩

activity.cs 中的代码来自新的/未修改的项目

using System;

using Android.Widget;
using Android.OS;

namespace helloworld_a3
{
    [Activity(Label = "helloworld_a3", MainLauncher = true, Icon = "@drawable/icon")]
    public class Activity1 : Activity
    {
        int count = 1;

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

            // Set our view from the "main" layout resource
            SetContentView(Resource.Layout.Main);

            // Get our button from the layout resource,
            // and attach an event to it
            Button button = FindViewById<Button>(Resource.Id.MyButton);

            button.Click += delegate { button.Text = string.Format("{0} clicks!", count++); };
        }
    }
}
