重新想象 Windows 8 Store Apps 之?ListView 和 GridView
示例
1、ListView 的 Demo
ListViewDemo.xaml
<Page x:Class="XamlDemo.Controls.ListViewDemo" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:XamlDemo.Controls" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d"> <Page.Resources> <DataTemplate x:Key="ItemTemplate"> <StackPanel Orientation="Vertical"> <TextBlock TextWrapping="Wrap" FontSize="14.667" Text="{Binding Name}" HorizontalAlignment="Left" /> <TextBlock TextWrapping="Wrap" FontSize="14.667" Text="{Binding Age}" HorizontalAlignment="Left"/> </StackPanel> </DataTemplate> <Style x:Key="ItemContainerStyle" TargetType="ListViewItem"> <Setter Property="Width" Value="292" /> <Setter Property="Height" Value="80" /> <Setter Property="Padding" Value="0" /> <!-- 即使将 Margin 设置为“0”，也无法去掉 item 之间的 margin 如果想要去掉 item 之间的 margin，请将此 Margin 属性设置为“-4” --> <Setter Property="Margin" Value="0" /> <Setter Property="Background" Value="Blue" /> </Style> </Page.Resources> <Grid Background="Transparent"> <Grid Margin="120 0 0 0"> <TextBlock Name="lblMsg" FontSize="14.667" /> <StackPanel Orientation="Horizontal" VerticalAlignment="Top" Margin="0 30 0 0"> <CheckBox Name="chkIsSwipeEnabled" Content="IsSwipeEnabled" /> <CheckBox Name="chkIsItemClickEnabled" Content="IsItemClickEnabled" Margin="10 0 0 0" /> </StackPanel> <!--后台绑定方式为 ListView 提供数据--> <ListView x:Name="listView" Width="300" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="0 60 10 10" BorderThickness="1" BorderBrush="Red" Background="LightBlue" ItemTemplate="{StaticResource ItemTemplate}" ItemContainerStyle="{StaticResource ItemContainerStyle}" ScrollViewer.VerticalScrollBarVisibility="Auto" ScrollViewer.HorizontalScrollBarVisibility="Auto" SelectionMode="Single" SelectionChanged="listView_SelectionChanged_1" IsSwipeEnabled="{Binding IsChecked, ElementName=chkIsSwipeEnabled}" IsItemClickEnabled="{Binding IsChecked, ElementName=chkIsItemClickEnabled}" ItemClick="listView_ItemClick_1"> </ListView> <!-- xaml 方式为 ListView 添加内容 <ListView> <ListView.Items> <ListViewItem> ... </ListViewItem> <ListViewItem> ... </ListViewItem> ... </ListView.Items> </ListView> --> </Grid> </Grid></Page>ListViewDemo.xaml.cs
/* * ListView - 列表控件 * IsItemClickEnabled - item 是否可被点击 * IsSwipeEnabled - 是否支持 swipe 操作（对于 ListView 来说，左右猛击 item 称之为 swipe） * SelectionMode - item 的选中模式（Windows.UI.Xaml.Controls.ListViewSelectionMode 枚举） * None - 不能被选中 * Single - 只能单选 * Multiple - 仅通过鼠标多选 * Extended - 通过鼠标和辅助键多选（ctrl 或 shift） * SelectedItems - 被选中的 items 集合 * ItemClick - item 被单击时触发的事件 * SelectAll() - 选中全部 items * ScrollIntoView(object item, ScrollIntoViewAlignment alignment) - 滚动到指定的 item * ScrollIntoViewAlignment.Default - 与该 item 的最近边缘对齐 * ScrollIntoViewAlignment.Leading - 与该 item 的前边缘对齐 * * * 注： * IsItemClickEnabled == false && IsSwipeEnabled == false 无法响应单击事件，单击则意味着选中，无法 swipe * IsItemClickEnabled == true && IsSwipeEnabled == false 可以响应单击事件，无法响应选中事件，无法 swipe * IsItemClickEnabled == false && IsSwipeEnabled == true 无法响应单击事件，单击和 swipe 均意味着选中 * IsItemClickEnabled == true && IsSwipeEnabled == true 可以响应单击事件，swipe 则意味着选中 * * 关于 SemanticZoom, item的拖动, item的尺寸可变等之后通过 GridView 来介绍 * * 关于分页加载内容在“数据绑定”一节做介绍 */using System.Collections.Generic;using Windows.UI.Xaml.Controls;using XamlDemo.Model;namespace XamlDemo.Controls{ public sealed partial class ListViewDemo : Page { public ListViewDemo() { this.InitializeComponent(); // 绑定数据 List<Employee> dataSource = TestData.GetEmployees(); listView.ItemsSource = dataSource; } // 单击行为的事件 private void listView_ItemClick_1(object sender, ItemClickEventArgs e) { lblMsg.Text = "被单击的 employee 的 name 为：" + (e.ClickedItem as Employee).Name; } // 选中行为的事件 private void listView_SelectionChanged_1(object sender, SelectionChangedEventArgs e) { if (e.AddedItems.Count > 0) lblMsg.Text = "此次操作被选中的 employee 的 name 为：" + (e.AddedItems[0] as Employee).Name; else lblMsg.Text = "此次操作没有被选中的 employee"; } }}
2、GridView 的 Demo
GridView/Demo.xaml
<Page x:Class="XamlDemo.Controls.GridView.Demo" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:XamlDemo.Controls.GridView" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d"> <Page.Resources> <DataTemplate x:Key="ItemTemplate"> <StackPanel Orientation="Vertical"> <TextBlock TextWrapping="Wrap" FontSize="14.667" Text="{Binding Name}" HorizontalAlignment="Left" /> <TextBlock TextWrapping="Wrap" FontSize="14.667" Text="{Binding Age}" HorizontalAlignment="Left"/> </StackPanel> </DataTemplate> <Style x:Key="ItemContainerStyle" TargetType="GridViewItem"> <Setter Property="Width" Value="292" /> <Setter Property="Height" Value="80" /> <!-- 即使将 Margin 设置为“0”，也无法去掉 item 之间的 margin 如果想要去掉 item 之间的 margin，请将此 Margin 属性设置为“-4” --> <Setter Property="Margin" Value="0" /> <Setter Property="Background" Value="Blue" /> </Style> <ItemsPanelTemplate x:Key="ItemsPanel"> <!-- 注：WrapGrid 继承自 VirtualizingPanel，而 VariableSizedWrapGrid 并未继承 VirtualizingPanel --> <WrapGrid MaximumRowsOrColumns="3" Orientation="Vertical" VerticalChildrenAlignment="Top" HorizontalChildrenAlignment="Left" /> </ItemsPanelTemplate> </Page.Resources> <Grid Background="Transparent"> <StackPanel Margin="120 0 0 0"> <TextBlock Name="lblMsg" FontSize="14.667" /> <StackPanel Orientation="Horizontal" Margin="0 10 0 0"> <CheckBox Name="chkIsSwipeEnabled" Content="IsSwipeEnabled" /> <CheckBox Name="chkIsItemClickEnabled" Content="IsItemClickEnabled" Margin="10 0 0 0" /> </StackPanel> <!--后台绑定方式为 ListView 提供数据--> <GridView x:Name="gridView" VerticalAlignment="Top" Margin="0 10 10 0" BorderThickness="1" BorderBrush="Red" Background="LightBlue" ItemTemplate="{StaticResource ItemTemplate}" ItemContainerStyle="{StaticResource ItemContainerStyle}" ItemsPanel="{StaticResource ItemsPanel}" ScrollViewer.VerticalScrollBarVisibility="Auto" ScrollViewer.HorizontalScrollBarVisibility="Auto" SelectionMode="Single" SelectionChanged="gridView_SelectionChanged_1" IsSwipeEnabled="{Binding IsChecked, ElementName=chkIsSwipeEnabled}" IsItemClickEnabled="{Binding IsChecked, ElementName=chkIsItemClickEnabled}" ItemClick="gridView_ItemClick_1"> </GridView> <!-- xaml 方式为 ListView 添加内容 <GridView> <GridView.Items> <GridViewItem> ... </GridViewItem> <GridViewItem> ... </GridViewItem> ... </GridView.Items> </GridView> --> </StackPanel> </Grid></Page>GridView/Demo.xaml.cs
/* * GridView - 网格控件 * IsItemClickEnabled - item 是否可被点击 * IsSwipeEnabled - 是否支持 swipe 操作（对于 GridView 来说，上下猛击 item 称之为 swipe） * SelectionMode - item 的选中模式（Windows.UI.Xaml.Controls.ListViewSelectionMode 枚举） * None - 不能被选中 * Single - 只能单选 * Multiple - 仅通过鼠标多选 * Extended - 通过鼠标和辅助键多选（ctrl 或 shift） * SelectedItems - 被选中的 items 集合 * ItemClick - item 被单击时触发的事件 * SelectAll() - 选中全部 items * ScrollIntoView(object item, ScrollIntoViewAlignment alignment) - 滚动到指定的 item * ScrollIntoViewAlignment.Default - 与该 item 的最近边缘对齐 * ScrollIntoViewAlignment.Leading - 与该 item 的前边缘对齐 * * * 注： * IsItemClickEnabled == false && IsSwipeEnabled == false 无法响应单击事件，单击则意味着选中，无法 swipe * IsItemClickEnabled == true && IsSwipeEnabled == false 可以响应单击事件，无法响应选中事件，无法 swipe * IsItemClickEnabled == false && IsSwipeEnabled == true 无法响应单击事件，单击和 swipe 均意味着选中 * IsItemClickEnabled == true && IsSwipeEnabled == true 可以响应单击事件，swipe 则意味着选中 */using System.Collections.Generic;using Windows.UI.Xaml.Controls;using XamlDemo.Model;namespace XamlDemo.Controls.GridView{ public sealed partial class Demo : Page { public Demo() { this.InitializeComponent(); // 绑定数据 List<Employee> dataSource = TestData.GetEmployees(); gridView.ItemsSource = dataSource; } // 单击行为的事件 private void gridView_ItemClick_1(object sender, ItemClickEventArgs e) { lblMsg.Text = "被单击的 employee 的 name 为：" + (e.ClickedItem as Employee).Name; } // 选中行为的事件 private void gridView_SelectionChanged_1(object sender, SelectionChangedEventArgs e) { if (e.AddedItems.Count > 0) lblMsg.Text = "此次操作被选中的 employee 的 name 为：" + (e.AddedItems[0] as Employee).Name; else lblMsg.Text = "此次操作没有被选中的 employee"; } }}
