在Xamarin表单的XAML中包含按钮时，如何解决此异常？

Question

I am new to XAML and Xamarin and want to build a test app on my android device. On the first page there's a button that directs to an other page. Here's a piece of the C# code HomePage.xaml.cs:

public void Clicked(object sender, EventArgs ea)
{
    Navigation.PushModalAsync (new SecondPage ());
}

On the second page I want to load an image and a button, but as soon as I include the button, I get this exception when running the app: java.lang.reflect.InvocationTargetException . Without the button, everything works fine. Here is the xaml code of the image and the button of the second page:

<Image  Source = "image.png" 
            x:Name="image"
            VerticalOptions="Start">
    <Image.GestureRecognizers>
            <TapGestureRecognizer
            Tapped="ImageTapped"/>
    </Image.GestureRecognizers>
</Image>
<Button Text="Text"
            BackgroundColor="Aqua"
            TextColor="White"
            VerticalOptions="EndAndExpand"/>

And here the C# code of the "ImageTapped" function:

public void ImageTapped(object sender, EventArgs ea)
{
    image.IsVisible = false;
}

I have no idea what I am doing wrong and I would really appreciate it if somebody could me!

在使用<ContentPage.Content>之前，我只是通过使用<StackLayout></StackLayout>解决了该问题。
