Question

我想知道您是否可以帮助我了解 Xamarin 教程中的编程语言 C#（按钮添加动态选项卡），我可以添加一个按钮来添加选项卡，例如 firefox 中的选项卡

You can add tabs dynamically but have no idea what you mean like in firefox. To add tabs dynamically you can do something like this:

public class MainActivity : Activity
{
    private int _count; 

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

        SetContentView(Resource.Layout.Main);
        var button = FindViewById<Button>(Resource.Id.MyButton);

        ActionBar.NavigationMode = ActionBarNavigationMode.Tabs;

        button.Click += AddTab;
    }

    private void AddTab(object sender, EventArgs e)
    {
        _count += 1;
        var tab = ActionBar.NewTab();
        tab.SetTag("Tab" + _count);
        tab.SetText("tab - " + _count);
        var temp = _count;
        tab.TabSelected +=
            (o, args) => { Toast.MakeText(this, "Tab " + temp + " selected!", ToastLength.Long).Show(); };
        ActionBar.AddTab(tab);
    }
}
