我想在第一页上创建一个图库图像包含该类别的缩略图,当选择缩略图时,它将打开图像和翻转视图中选定图像的描述(可以向右滑动当在之前和之后的图像中选择缩略图时向左移动)。将它应用到flipview时遇到困难。图片库与Flipview
代码: XAML的MainPage
<GridView
x:Name="itemGridView"
AutomationProperties.AutomationId="ItemGridView"
AutomationProperties.Name="Grouped Items"
Grid.RowSpan="3"
Padding="116,137,40,46"
ItemsSource="{Binding Source={StaticResource groupedItemsViewSource}}"
SelectionMode="None"
IsSwipeEnabled="false"
IsItemClickEnabled="True"
ItemClick="ItemView_ItemClick" Background="#FF6996D1" >
<GridView.ItemTemplate>
<DataTemplate>
<Grid HorizontalAlignment="Left" Width="240" Height="180">
<Border>
<Image Source="{Binding ImagePath}" Stretch="Uniform" AutomationProperties.Name="{Binding Title}"/>
</Border>
</Grid>
</DataTemplate>
</GridView.ItemTemplate>
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<ItemsWrapGrid GroupPadding="0,0,70,0"/>
</ItemsPanelTemplate>
</GridView.ItemsPanel>
</GridView>
的MainPage:
public MainPage()
{
this.InitializeComponent();
Gallery();
}
private async void Gallery()
{
var sampleDataGroups = await DataItemSource.GetGroupsAsync();
this.DefaultViewModel["Groups"] = sampleDataGroups;
}
void ItemView_ItemClick(object sender, ItemClickEventArgs e)
{
// Navigate to the appropriate destination page, configuring the new page
// by passing required information as a navigation parameter
var itemId = ((SampleDataItem)e.ClickedItem).UniqueId;
this.Frame.Navigate(typeof(ItemDetailPage), itemId);
}
ItemDetailPage XAML:
<Grid Grid.Row="1" x:Name="contentRegion" Background="#FF6996D1">
<Image Source="{Binding ImagePath}" HorizontalAlignment="Left" Height="559" Margin="84,20,0,49" VerticalAlignment="Center" Width="732"/>
<ScrollViewer x:Name="myScroll" VerticalScrollBarVisibility="Auto" Margin="852,60,50,91" VerticalScrollMode="Auto" HorizontalScrollBarVisibility="Auto">
<TextBlock Text="{Binding Description}" TextWrapping="Wrap" Height="2210" Width="425" FontSize="27" TextAlignment="Justify" />
</ScrollViewer>
</Grid>
ItemDetailPage代码:
public ItemDetailPage()
{
this.InitializeComponent();
this.navigationHelper = new NavigationHelper(this);
this.navigationHelper.LoadState += navigationHelper_LoadState;
}
private async void navigationHelper_LoadState(object sender, LoadStateEventArgs e)
{
// TODO: Create an appropriate data model for your problem domain to replace the sample data
var item = await DataItemSource.GetItemAsync((String)e.NavigationParameter);
this.DefaultViewModel["Item"] = item;
}
protected override void OnNavigatedTo(NavigationEventArgs e)
{
navigationHelper.OnNavigatedTo(e);
}
protected override void OnNavigatedFrom(NavigationEventArgs e)
{
navigationHelper.OnNavigatedFrom(e);
}
