我正在尝试创建简单的多屏幕应用程序。

我添加了Content Pagebutton

MapPage.xaml.cs

[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class MapPage : ContentPage
{
    public MapPage ()
    {
        InitializeComponent ();
    }

    void ShowMap(object s, EventArgs e)
    {
    }
}

MapPage.xaml

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:local="clr-namespace:App14"
             x:Class="App14.MapPage">
    <ContentPage.Content>
        <StackLayout>
            <Label Text="Welcome to Xamarin Forms!" />
            <Button Text="show map" 
                    Clicked="ShowMap"/>
        </StackLayout>
    </ContentPage.Content>
</ContentPage>

我收到错误:ShowMap Method does not have correct signature

我做错了什么?

答案 0 :(得分:1)

将事件处理程序从private(默认情况下,如果未指定)更改为protected

protected void ShowMap(object s, EventArgs e)
        {

        }
