FlipView控制項和我們常見到的ListView、ListBox控制項很像,今天拿它來吹一吹,是因為這個控制項還挺新鮮的。
要說用文字來介紹這個控制項,還真不夠生動也欠缺活潑,不過,其實這個控制項咱們還是見得不少的,如果你經常到市集下載應用的話,你肯定見過。就是這個:
就是這玩意兒,左右各有一個按鈕用來導航視圖,每次只能查看一個視圖,比較適合用於圖片瀏覽。
廢話少說,我們來做兩個執行個體,第一個是手動添加項,第二個是資料繫結的。
好的,先做第一個,很簡單,我們在FlipView中放三個項,每個項的內容就是一個Image,看看下面的XAML就會明白了。
<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>
然後,我們運行一下。
好的,現在來看看第二個例子,資料繫結的。
既然要資料繫結了,肯定要資料來源的了。因此,我們先偽造一些資料,注意,這資料是偽造的,如有雷同,純屬自然造化。
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 = "小趙", Age = 20, Sex = "男", Email = "rubbish@163.com", Remark = "此人人品低下,經常在公用場所撒尿。" }); this.Add(new Student { Name = "小王", Age = 18, Email = "kaozhu@163.com", Sex = "女", Remark = "膽大心細臉皮厚。" }); this.Add(new Student { Name = "小劉", Age = 21, Email = "ak800@foxmail.com", Sex = "男", Remark = "這廝是牛人啊。" }); } }
然後,在XAML中進行綁定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="年齡:"/> <TextBlock Style="{StaticResource t2}" Grid.Column="1" Grid.Row="1" Text="{Binding Age}"/> <TextBlock Style="{StaticResource t1}" Grid.Column="0" Grid.Row="2" Text="性別:"/> <TextBlock Style="{StaticResource t2}" Grid.Column="1" Grid.Row="2" Text="{Binding Sex}"/> <TextBlock Style="{StaticResource t1}" Grid.Column="0" Grid.Row="3" Text="電郵:"/> <TextBlock Style="{StaticResource t2}" Grid.Column="1" Grid.Row="3" Text="{Binding Email}"/> <TextBlock Style="{StaticResource t1}" Grid.Column="0" Grid.Row="4" Text="備忘:"/> <TextBlock Style="{StaticResource t2}" Grid.Column="1" Grid.Row="4" Text="{Binding Remark}"/> </Grid> </DataTemplate> </FlipView.ItemTemplate> </FlipView> </Grid></Page>
切換到程式碼檢視,在MainPage類的建構函式中加入以下代碼,設定FlipView的資料來源。
public MainPage() { this.InitializeComponent(); TestDataSource source = new TestDataSource(); this.fv.ItemsSource = source; }
如果一切正常,運行後,你應該能看到以下效果。
