FlipView控件和我们常见到的ListView、ListBox控件很像,今天拿它来吹一吹,是因为这个控件还挺新鲜的。
要说用文字来介绍这个控件,还真不够生动也欠缺活泼,不过,其实这个控件咱们还是见得不少的,如果你经常到应用商店下载应用的话,你肯定见过。就是这个:
就是这玩意儿,左右各有一个按钮用来导航视图,每次只能查看一个视图,比较适合用于图片浏览。
废话少说,我们来做两个实例,第一个是手动添加项,第二个是数据绑定的。
好的,先做第一个,很简单,我们在FlipView中放三个项,每个项的内容就是一个Image,看看下面的XAML就会明白了。
<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}"> <FlipView Margin="300,150"> <FlipViewItem> <Image Stretch="Uniform" Source="http://pica.nipic.com/2008-01-17/2008117205617816_2.jpg"/> </FlipViewItem> <FlipViewItem> <Image Stretch="Uniform" Source="http://pic4.nipic.com/20090914/1593169_000535237178_2.jpg"/> </FlipViewItem> <FlipViewItem> <Image Stretch="Uniform" Source="http://www.zwtuu.com.cn/upload/2008_10/08102721166304.jpg"/> </FlipViewItem> </FlipView> </Grid>
然后,我们运行一下。
好的,现在来看看第二个例子,数据绑定的。
既然要数据绑定了,肯定要数据源的了。因此,我们先伪造一些数据,注意,这数据是伪造的,如有雷同,纯属自然造化。
public class Student { public string Name { get; set; } public int Age { get; set; } public string Sex { get; set; } public string Email { get; set; } public string Remark { get; set; } } public class TestDataSource : System.Collections.ObjectModel.ObservableCollection<Student> { public TestDataSource() { this.Add(new Student { Name = "小赵", Age = 20, Sex = "男", Email = "[email protected]", Remark = "此人人品低下,经常在公共场所撒尿。" }); this.Add(new Student { Name = "小王", Age = 18, Email = "[email protected]", Sex = "女", Remark = "胆大心细脸皮厚。" }); this.Add(new Student { Name = "小刘", Age = 21, Email = "[email protected]", Sex = "男", Remark = "这厮是牛人啊。" }); } }
然后,在XAML中进行绑定UI。
<Page x:Class="FlipViewExample2.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:FlipViewExample2" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d"> <Page.Resources> <Style x:Key="t1" TargetType="TextBlock"> <Setter Property="FontSize" Value="20"/> <Setter Property="FontWeight" Value="Bold"/> <Setter Property="VerticalAlignment" Value="Top"/> <Setter Property="Margin" Value="3,2,6,2"/> </Style> <Style x:Key="t2" TargetType="TextBlock"> <Setter Property="FontSize" Value="19"/> <Setter Property="Margin" Value="3.2,2,3,2"/> <Setter Property="TextWrapping" Value="Wrap"/> </Style> <Style x:Key="jlipviewItemStyle" TargetType="FlipViewItem"> <Setter Property="HorizontalContentAlignment" Value="Center"/> <Setter Property="VerticalContentAlignment" Value="Center"/> </Style> </Page.Resources> <Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}"> <FlipView x:Name="fv" Width="500" Height="150" VerticalAlignment="Center" HorizontalAlignment="Center" ItemContainerStyle="{StaticResource jlipviewItemStyle}"> <FlipView.ItemTemplate> <DataTemplate> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="auto"/> <ColumnDefinition Width="*"/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="auto"/> <RowDefinition Height="auto"/> <RowDefinition Height="auto"/> <RowDefinition Height="auto"/> <RowDefinition Height="auto"/> </Grid.RowDefinitions> <TextBlock Style="{StaticResource t1}" Grid.Column="0" Grid.Row="0" Text="姓名:"/> <TextBlock Style="{StaticResource t2}" Grid.Column="1" Grid.Row="0" Text="{Binding Name}"/> <TextBlock Style="{StaticResource t1}" Grid.Column="0" Grid.Row="1" Text="年龄:"/> <TextBlock Style="{StaticResource t2}" Grid.Column="1" Grid.Row="1" Text="{Binding Age}"/> <TextBlock Style="{StaticResource t1}" Grid.Column="0" Grid.Row="2" Text="性别:"/> <TextBlock Style="{StaticResource t2}" Grid.Column="1" Grid.Row="2" Text="{Binding Sex}"/> <TextBlock Style="{StaticResource t1}" Grid.Column="0" Grid.Row="3" Text="电邮:"/> <TextBlock Style="{StaticResource t2}" Grid.Column="1" Grid.Row="3" Text="{Binding Email}"/> <TextBlock Style="{StaticResource t1}" Grid.Column="0" Grid.Row="4" Text="备注:"/> <TextBlock Style="{StaticResource t2}" Grid.Column="1" Grid.Row="4" Text="{Binding Remark}"/> </Grid> </DataTemplate> </FlipView.ItemTemplate> </FlipView> </Grid> </Page>
切换到代码视图,在MainPage类的构造函数中加入以下代码,设置FlipView的数据源。
public MainPage() { this.InitializeComponent(); TestDataSource source = new TestDataSource(); this.fv.ItemsSource = source; }
如果一切正常,运行后,你应该能看到以下效果。
