WP 8.1中ThemeTransition(ReorderThemeTransition和PaneThemeTransition)
回顾下动画过渡效果ThemeTransition有哪些:
EntranceThemeTransition - 页面间跳转时的过渡效果(已介绍,不再重复了)
ContentThemeTransition - 内容改变时的过渡效果(已介绍,不再重复了)
RepositionThemeTransition - 位置改变时的过渡效果(已介绍,不再重复了)
PopupThemeTransition - 弹出时的过渡效果(在Popup那一篇博客中出现过,不再重复了)
AddDeleteThemeTransition - 添加项或删除项时的过渡效果(已介绍,不再重复了)
ReorderThemeTransition - 对集合中的元素重新排序时的过渡效果(本篇介绍)
PaneThemeTransition - 基于边缘的较大 UI 滑入和滑出时的过渡效果(本篇介绍)
EdgeUIThemeTransition - 基于边缘的较小 UI 滑入和滑出时的过渡效果(在Popup那一篇博客中出现过,不再重复了)
先是ReorderThemeTransition - 对集合中的元素重新排序时的过渡效果
贴代码之前只要注意itemsControl.Items.Insert(1, rectangle)这句代码即可
表示向ItemsControl控件Items集合中插入Rectangle元素,而位置是从第二个开始插入,原来第二个位置的挤到第三
前台XAML:
<Page x:Class="TestUnion.ReorderThemeTransitionDemo" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:TestUnion" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"> <Grid> <StackPanel> <Button x:Name="btnAdd" Content="添加" Click="btnAdd_Click" /> <ItemsControl x:Name="itemsControl"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <WrapGrid> <WrapGrid.ChildrenTransitions> <TransitionCollection> <ReorderThemeTransition/> </TransitionCollection> </WrapGrid.ChildrenTransitions> </WrapGrid> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.Items> <Rectangle Width="300" Height="50" Fill="Red"/> <Rectangle Width="300" Height="50" Fill="Blue"/> <Rectangle Width="300" Height="50" Fill="Green"/> </ItemsControl.Items> <ItemsControl.Template> <ControlTemplate> <Border BorderBrush="Coral" BorderThickness="5"> <ItemsPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/> </Border> </ControlTemplate> </ItemsControl.Template> </ItemsControl> </StackPanel> </Grid> </Page>
后台.cs:
using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Runtime.InteropServices.WindowsRuntime; using Windows.Foundation; using Windows.Foundation.Collections; using Windows.UI; using Windows.UI.Xaml; using Windows.UI.Xaml.Controls; using Windows.UI.Xaml.Controls.Primitives; using Windows.UI.Xaml.Data; using Windows.UI.Xaml.Input; using Windows.UI.Xaml.Media; using Windows.UI.Xaml.Navigation; using Windows.UI.Xaml.Shapes; // “空白页”项模板在 http://go.microsoft.com/fwlink/?LinkID=390556 上有介绍 namespace TestUnion { /// <summary> /// 可用于自身或导航至 Frame 内部的空白页。 /// </summary> public sealed partial class ReorderThemeTransitionDemo : Page { public ReorderThemeTransitionDemo() { this.InitializeComponent(); } /// <summary> /// 在此页将要在 Frame 中显示时进行调用。 /// </summary> /// <param name="e">描述如何访问此页的事件数据。 /// 此参数通常用于配置页。</param> protected override void OnNavigatedTo(NavigationEventArgs e) { } private void btnAdd_Click(object sender, RoutedEventArgs e) { Rectangle rectangle = new Rectangle(); Random random = new Random(); rectangle.Width = 300; rectangle.Height = 50; rectangle.Fill = new SolidColorBrush(Color.FromArgb(255, (byte)random.Next(0, 255), (byte)random.Next(0, 255), (byte)random.Next(255))); itemsControl.Items.Insert(1, rectangle); } } }
运行截图:
初始界面以及点击一次添加按钮,点击多次添加按钮:
(前后对比会发现从第二个位置开始插入的)
再是PaneThemeTransition - 基于边缘的较大 UI 滑入和滑出时的过渡效果
需要注意的是PaneThemeTransition和EdgeUIThemeTransition的属性Edge
Edge ----- 用来设置UI从屏幕那一边滑入滑出
例如Edge="right",则说明UI会从屏幕右侧滑入
至于Popup的HorizontalOffset,VerticalOffset,IsLightDismissEnabled
以及如何在后台设置PaneThemeTransition和EdgeUIThemeTransition的Edge属性
可以参照我的专门关于Popup控件的那篇篇博客:Windows Phone 8.1中的Popup控件
前台XAML:
<Page x:Class="TestUnion.PaneThemeTransitionDemo" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:TestUnion" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"> <Grid> <StackPanel Orientation="Vertical"> <Popup x:Name="popup" IsLightDismissEnabled="True"> <Popup.Child> <!--大UI滑入滑出--> <Border BorderBrush="Coral" Background="Green" BorderThickness="5" Width="400" Height="500"> <TextBlock Text="这是Popup里面的内容" FontSize="30"/> </Border> <!--小UI滑入滑出--> <!--<Border BorderBrush="Coral" Background="Green" BorderThickness="5" Width="350" Height="100"> <TextBlock Text="这是Popup里面的内容" FontSize="30"/> </Border>--> </Popup.Child> <Popup.ChildTransitions> <TransitionCollection> <!--默认Edge=right--> <!--大UI滑入滑出过渡效果--> <PaneThemeTransition Edge="Left" /> <!--小UI滑入滑出过渡效果--> <!--<EdgeUIThemeTransition Edge="Right" />--> </TransitionCollection> </Popup.ChildTransitions> </Popup> <Button x:Name="btnShowPane" Content="显示Pane" Click="btnShowPane_Click"/> </StackPanel> </Grid> </Page>
后台.cs:
using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Runtime.InteropServices.WindowsRuntime; using Windows.Foundation; using Windows.Foundation.Collections; using Windows.UI.Xaml; using Windows.UI.Xaml.Controls; using Windows.UI.Xaml.Controls.Primitives; using Windows.UI.Xaml.Data; using Windows.UI.Xaml.Input; using Windows.UI.Xaml.Media; using Windows.UI.Xaml.Navigation; // “空白页”项模板在 http://go.microsoft.com/fwlink/?LinkID=390556 上有介绍 namespace TestUnion { /// <summary> /// 可用于自身或导航至 Frame 内部的空白页。 /// </summary> public sealed partial class PaneThemeTransitionDemo : Page { public PaneThemeTransitionDemo() { this.InitializeComponent(); } /// <summary> /// 在此页将要在 Frame 中显示时进行调用。 /// </summary> /// <param name="e">描述如何访问此页的事件数据。 /// 此参数通常用于配置页。</param> protected override void OnNavigatedTo(NavigationEventArgs e) { } private void btnShowPane_Click(object sender, RoutedEventArgs e) { if(!popup.IsOpen) { popup.IsOpen = true; } } } }

初始界面和点击显示Pane的按钮:
还是那句话,截图看不了中间过渡动画效果,大家还是自行写一下感受下,这样印象才深一些
実に おもしろい
