给出以下“项目详细信息”页面:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="App1.Views.ItemDetailPage"
Title="{Binding Title}">
<ScrollView>
<StackLayout Spacing="2" Padding="15">
<Label Text="Date:" FontSize="Small" FontAttributes="Bold"/>
<Label Text="{Binding Item.Date}" FontSize="Small" />
<Label Text="School:" FontSize="Small" FontAttributes="Bold"/>
<Label Text="{Binding Item.School}" FontSize="Small"/>
<Label Text="Description:" FontSize="Small" FontAttributes="Bold" />
<Label Text="{Binding Item.Description}" FontSize="Small"/>
<Label Text="Condition:" FontSize="Small" FontAttributes="Bold"/>
<Label Text="{Binding Item.Condition}" FontSize="Small"/>
<Label Text="Offnormal:" FontSize="Small" FontAttributes="Bold"/>
<Label Text="{Binding Item.Offnormal}" FontSize="Small"/>
<Label Text="EventType:" FontSize="Small" FontAttributes="Bold"/>
<Label Text="{Binding Item.EventType}" FontSize="Small"/>
<Label Text="BaseState:" FontSize="Small" FontAttributes="Bold"/>
<Label Text="{Binding Item.BaseState}" FontSize="Small"/>
<Label Text="Code:" FontSize="Small" FontAttributes="Bold"/>
<Label Text="{Binding Item.Code}" FontSize="Small"/>
<Label Text="Account:" FontSize="Small" FontAttributes="Bold"/>
<Label Text="{Binding Item.Account}" FontSize="Small"/>
<Label Text="RestoreFor:" FontSize="Small" FontAttributes="Bold"/>
<Label Text="{Binding Item.RestoreFor}" FontSize="Small"/>
</StackLayout>
</ScrollView>
</ContentPage>
如何在网格或列表视图中显示? 当我尝试将相同的/相似的代码用于将SelectedItem属性发送到此详细信息页面的Listview / Grid时,我得到了除标题之外的空白页面。
任何帮助将不胜感激。
谢谢

我知道了。为了清楚起见,我的问题是发送SelectedItem并可以很好地用于Label绑定,但是ListView ItemsSource需要一个List。我对此进行了相应的更改,并且可以进行以下工作:
<ScrollView>
<!--Spacing="2" Padding="15">-->
<StackLayout >
<Label Text="Date:" FontSize="Small" FontAttributes="Bold"/>
<Label Text="{Binding Item[0].Date}" FontSize="Small" />
<ListView x:Name="ItemsListView2"
ItemsSource="{Binding Item}"
VerticalOptions="FillAndExpand"
HasUnevenRows="true"
IsRefreshing="{Binding IsBusy, Mode=OneWay}"
CachingStrategy="RecycleElement">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Grid BackgroundColor="White" ColumnSpacing="0" RowSpacing="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Label Grid.Column="0" Text ="{Binding Date}" HorizontalOptions="Fill" BackgroundColor="LightBlue" HorizontalTextAlignment="Center" Margin="1"></Label>
</Grid>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
</ScrollView>
