控件显示在设计器中但不在模拟器中

问题描述

这是我的第一个 Xamarin 应用程序.我在 Visual Studio 中设置了环境，并且有一个可以在 Android 模拟器中运行的模板项目.

This is my first Xamarin app. I have my environment set up in Visual Studio, and have a template project which I can run in the Android emulator.

将几个控件拖放到设计器界面后，我发现当我在模拟器中运行应用程序时，我添加的两个控件(一个按钮和一个开关)都没有显示在模拟器中.

Having dragged and dropped a couple of controls on to the designer surface, I find that when I run the application in the emulator, neither of the two controls that I have added (a button and a switch) display in the emulator.

我试过了:

• 清洁溶液
• 重建解决方案
• 手动删除 bin 和目标文件
• 在项目 Android 选项中取消选中使用快速部署"
• 从模拟器卸载

但每次都得到相同的结果.

But with the same result each time.

[删除项目文件]

我错过了什么吗?

推荐答案

刚刚下载并运行了您的代码.取消注释 SetContentView (Resource.Layout.Main); 它对我有用.

Just downloaded your code and ran it. Uncommenting SetContentView (Resource.Layout.Main); it worked to me.

[Activity(Label = "Tgo.AndroidApp", MainLauncher = true, Icon = "@drawable/icon")]
public class MainActivity : Activity
{
    protected override void OnCreate(Bundle bundle)
    {
        base.OnCreate(bundle);

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