Xamarin Forms如何将ListView用于显示字符串[]，该字符串是显示在CarouselView中的同一JS

Question

所有字段都显示ok，只有Specilities字符串[]显示错误。。。请记住，json响应上有两个不同的fid，我们有Speciality，它是OK和show OK……我们有Specilities字符串[]，问题在哪里。。。。检查json响应

这是json响应

Answer 1

此

<ListView ItemsSource="{Binding .}"

应该是

<ListView ItemsSource="{Binding Specialities}"

和这个

<Label FontSize="3" Text="{Binding Specialities}" />

应该是

<Label FontSize="3" Text="{Binding .}" />
