1. 重写panorama page, 使其达到全屏

 public class PanoramaFullScreen : Panorama { protected override System.Windows.Size MeasureOverride(System.Windows.Size availableSize) { availableSize.Width += 48; return base.MeasureOverride(availableSize); } }

2. 去掉 title 和 header，调整好margin

3. 在codebehind 中控制页面跳转

 private TouchPoint first; private const int DetectRightGesture = 20; private int startIndex = 0; private readonly int endIndex; public WhatsNewView() { InitializeComponent(); endIndex = MyStartScreen.Items.Count - 1; MyStartScreen.IsHitTestVisible = false; MyStartScreen.IsEnabled = false; Touch.FrameReported += Touch_FrameReported; TouchPanel.EnabledGestures = GestureType.HorizontalDrag; } private void Touch_FrameReported(object sender, TouchFrameEventArgs e) { try { TouchPoint mainTouch = e.GetPrimaryTouchPoint(this); if (mainTouch.Action == TouchAction.Down) first = mainTouch; else if (mainTouch.Action == TouchAction.Up && TouchPanel.IsGestureAvailable) { if (mainTouch.Position.X - first.Position.X < -DetectRightGesture) { if (startIndex < endIndex) { MyStartScreen.SlideToPage(startIndex + 1, SlideTransitionMode.SlideLeftFadeOut); startIndex++; } else { NavigateToNextPage(); } } else if (mainTouch.Position.X - first.Position.X > DetectRightGesture) { if (startIndex > 0) { MyStartScreen.SlideToPage(startIndex - 1, SlideTransitionMode.SlideRightFadeOut); startIndex--; } } } } catch { } } private void ButtonBase_OnClick(object sender, RoutedEventArgs e) { NavigateToNextPage(); } private void NavigateToNextPage() { NavigationService.Navigate(new Uri("/Views/LoginPage.xaml", UriKind.Relative)); } protected override void OnNavigatedFrom(NavigationEventArgs e) { while (NavigationService.BackStack.Any()) { NavigationService.RemoveBackEntry(); } }

4. 补充： 拓展panorama 方法，使其跳转附带动画

 public static void SlideToPage(this Panorama self, int item, SlideTransitionMode slideMode) { var slideTransition = new SlideTransition { }; slideTransition.Mode = slideMode; ITransition transition = slideTransition.GetTransition(self); transition.Completed += delegate { self.DefaultItem = self.Items[item]; transition.Stop(); }; transition.Begin(); }

不足：

SlideTransitionMode SlideTransitionMode支持动画有限，一般达不到预期效果

方案2：

将所有图片水平排列，根据手势通过左右偏移来控制显示

 public static readonly DependencyProperty SlidePageIndexProperty = DependencyProperty.Register("SlidePageIndex", typeof(int), typeof(StartScreenView), null); public int SlidePageIndex { get { return (int)GetValue(SlidePageIndexProperty); } set { SetValue(SlidePageIndexProperty, value); } }

偏移量根据不同设备决定

 _uniformImageWidth = (int)Application.Current.Host.Content.ActualWidth;

手势控制

Touch.FrameReported += Touch_FrameReported; TouchPanel.EnabledGestures = GestureType.HorizontalDrag;

 private void Touch_FrameReported(object sender, TouchFrameEventArgs e) { try { TouchPoint mainTouch = e.GetPrimaryTouchPoint(this); if (mainTouch.Action == TouchAction.Down) first = mainTouch; else if (mainTouch.Action == TouchAction.Up && TouchPanel.IsGestureAvailable) { if (mainTouch.Position.X - first.Position.X < -DetectRightGesture) { if (SlidePageIndex == MaxSlidePageCount - 1) { NavigateToLoginPage(); } SlidePageIndex++; Slide(); } else if (mainTouch.Position.X - first.Position.X > DetectRightGesture) { if (SlidePageIndex == 0) return; SlidePageIndex--; Slide(); } } } catch { } }

滑动逻辑

 private void Slide() { var storyboard = new Storyboard(); var ani = new DoubleAnimation(); ani.To = SlidePageIndex * -_uniformImageWidth; ani.Duration = TimeSpan.FromSeconds(1.0f); ani.EasingFunction = new ElasticEase() { EasingMode = EasingMode.EaseInOut, Oscillations = 0 }; Storyboard.SetTarget(ani, this.Slider); Storyboard.SetTargetProperty(ani, new PropertyPath("(Canvas.Left)")); storyboard.Children.Add(ani); storyboard.Begin(); }

此页面不可以通过back键导航??

 protected override void OnNavigatedFrom(NavigationEventArgs e) { while (NavigationService.BackStack.Any()) { NavigationService.RemoveBackEntry(); } }
