如何顺利导航到不同的全景项目

在全景应用程序中，我添加了一些用户导航回某个全景项目的情况。 然而，这是在一次突然的运动中完成的。 有没有办法可以通过某种forms的过渡更顺利地完成这项行动？ 或类似的东西？

Answer 1

这段代码对我有用

SlideTransition slideTransition = new SlideTransition(); slideTransition.Mode = SlideTransitionMode.SlideRightFadeIn; ITransition transition = slideTransition.GetTransition(panorama_main); transition.Completed += delegate { transition.Stop(); }; PanoramaItem pItem = (PanoramaItem)panorama_main.Items[3]; panorama_main.DefaultItem = pItem; transition.Begin(); 

Answer 2

从Inder Kumar Rathore的回答和本页的答案我来这样做：

  #region navigation public enum MainPanoramaItem { None = -1, Mag, Scan, Account, Lists, More, Help, MainPanoramaItemCount } public void PanoramaNavigateTo(MainPanoramaItemitem) { int count = (int)MainPanoramaItem.MainPanoramaItemCount; int toPosition = (int)item; int nowPosition = panorama.SelectedIndex; bool left = false; if(nowPosition > toPosition){ int rightDelta = count - nowPosition + toPosition; int leftDelta = nowPosition - toPosition; left = rightDelta > leftDelta; } else { int leftDelta = count - nowPosition + toPosition; int rightDelta = nowPosition - toPosition; left = rightDelta > leftDelta; } SlideTransition slideTransition = new SlideTransition(); slideTransition.Mode = left ? SlideTransitionMode.SlideLeftFadeOut : SlideTransitionMode.SlideRightFadeOut; ITransition transition = slideTransition.GetTransition(panorama); transition.Completed += delegate { transition.Stop(); SlideTransition slideTransitionIn = new SlideTransition(); slideTransitionIn.Mode = left ? SlideTransitionMode.SlideLeftFadeIn : SlideTransitionMode.SlideRightFadeIn; ITransition transitionIn = slideTransitionIn.GetTransition(panorama); transitionIn.Completed += delegate { transitionIn.Stop(); }; panorama.SetValue(Panorama.SelectedItemProperty, panorama.Items[(int)item]); Panorama temp = panorama; LayoutRoot.Children.Remove(panorama); LayoutRoot.Children.Add(temp); LayoutRoot.UpdateLayout(); transitionIn.Begin(); }; transition.Begin(); } protected override void OnBackKeyPress(CancelEventArgs e) { if (panorama.DefaultItem != panorama.Items[(int)PanoramaItem.Mag]) { PanoramaNavigateTo(PanoramaItem.Mag); e.Cancel = true; } } #endregion 

在MainPage.xaml.cs中它使用淡出然后淡入并保持全景的标题在它的原始位置。 我不确定它是如何对真实的应用程序做出反应的，因为我的空洞很空洞。
