android - 在 Xamarin 中处理按钮单击事件

Question

我是 Xamarin 的新手，英语不是很好，无法阅读相关的手册。
有人可以告诉我如何在 Xamarin 的代码隐藏中处理此按钮的点击事件方法吗？

public class App : Application
{
    public App ()
    {
        // The root page of your application
        MainPage =new ContentPage{
            Content= new Button{Text="Click me",BackgroundColor=Color.Black,HorizontalOptions=LayoutOptions.Center,VerticalOptions=LayoutOptions.Center,TextColor=Color.White}
    };
}

Answer 1

public class App : Application
{
    public App ()
    {
        // The root page of your application
        MainPage =new LaunchPage();
    }
}
public class LaunchPage:ContentPage
{
    public LaunchPage ()
    {
        var button=new Button{Text="Hello World",BackgroundColor=Color.Black,HorizontalOptions=LayoutOptions.Center,VerticalOptions=LayoutOptions.Center,TextColor=Color.White};
        button.Clicked += ButtonClicked;
        Content = button;
    }
    void ButtonClicked(object sender, EventArgs args)
    {
        DisplayAlert ("Button Clicked", "This Button has been clicked", "OK");
    }
}
