问题描述

任何人都可以就如何在WinRT的应用程序检测简单的触摸手势解释一下吗？我尝试使用 GestureRecognizer 类，但它没有工作：

 公开的MainPage（）
    {
        this.InitializeComponent（）;
        Windows.UI.Input.GestureRecognizer克=新Windows.UI.Input.GestureRecognizer（）;
        gr.CrossSliding + = gr_CrossSliding;
        gr.Dragging + = gr_Dragging;
        gr.Holding + = gr_Holding;
        gr.ManipulationCompleted + = gr_ManipulationCompleted;
        gr.ManipulationInertiaStarting + = gr_ManipulationInertiaStarting;
        gr.ManipulationStarted + = gr_ManipulationStarted;
        gr.ManipulationUpdated + = gr_ManipulationUpdated;
        gr.RightTapped + = gr_RightTapped;
        gr.Tapped + = gr_Tapped;
        gr.GestureSettings = Windows.UI.Input.GestureSettings.ManipulationRotate | Windows.UI.Input.GestureSettings.ManipulationTranslateX | Windows.UI.Input.GestureSettings.ManipulationTranslateY |
        Windows.UI.Input.GestureSettings.ManipulationScale | Windows.UI.Input.GestureSettings.ManipulationRotateInertia | Windows.UI.Input.GestureSettings.ManipulationScaleInertia |
        Windows.UI.Input.GestureSettings.ManipulationTranslateInertia | Windows.UI.Input.GestureSettings.Tap;    }    无效gr_Tapped（Windows.UI.Input.GestureRecognizer发件人，Windows.UI.Input.TappedEventArgs参数）
    {
        的Debug.WriteLine（gr_Tapped）;
    }
    无效gr_RightTapped（Windows.UI.Input.GestureRecognizer发件人，Windows.UI.Input.RightTappedEventArgs参数）
    {
        的Debug.WriteLine（gr_RightTapped）;
    }
    无效gr_Holding（Windows.UI.Input.GestureRecognizer发件人，Windows.UI.Input.HoldingEventArgs参数）
    {
        的Debug.WriteLine（gr_Holding）;
    }
    无效gr_Dragging（Windows.UI.Input.GestureRecognizer发件人，Windows.UI.Input.DraggingEventArgs参数）
    {
        的Debug.WriteLine（gr_Dragging）;
    }
    无效gr_CrossSliding（Windows.UI.Input.GestureRecognizer发件人，Windows.UI.Input.CrossSlidingEventArgs参数）
    {
        的Debug.WriteLine（gr_CrossSliding）;
    }
    无效gr_ManipulationUpdated（Windows.UI.Input.GestureRecognizer发件人，Windows.UI.Input.ManipulationUpdatedEventArgs参数）
    {
        的Debug.WriteLine（gr_ManipulationUpdated）;
    }
    无效gr_ManipulationStarted（Windows.UI.Input.GestureRecognizer发件人，Windows.UI.Input.ManipulationStartedEventArgs参数）
    {
        的Debug.WriteLine（gr_ManipulationStarted）;
    }
    无效gr_ManipulationCompleted（Windows.UI.Input.GestureRecognizer发件人，Windows.UI.Input.ManipulationCompletedEventArgs参数）
    {
        的Debug.WriteLine（gr_ManipulationCompleted）;
    }
    无效gr_ManipulationInertiaStarting（Windows.UI.Input.GestureRecognizer发件人，Windows.UI.Input.ManipulationInertiaStartingEventArgs参数）
    {
        的Debug.WriteLine（gr_ManipulationInertiaStarting）;
    }

解决方案

如果你会发现MainPage类有，你可以无需创建一个单独的 GestureRecognizer 。您可以通过设置 this.ManipulationMode 到 ManipulationModes.All 启用。这将让你看到的MainPages响应螺纹， RightTapped ， ManipulationStarting ，在ManipulationStarted ，在ManipulationDelta 和在ManipulationCompleted 活动。

至于获得GestureRecongnizer根据本工作，此MSDN论坛发帖您将需要处理的MainPage的 PointerMoved ， PointerReleased 和指针pressed 事件，像这样。

  Windows.UI.Input.GestureRecognizer克=新Windows.UI.Input.GestureRecognizer（）;公众的MainPage（）
{
    this.InitializeComponent（）;
    this.Pointer pressed + = MainPage_Pointer pressed;
    this.PointerMoved + = MainPage_PointerMoved;
    this.PointerReleased + = MainPage_PointerReleased;
    gr.CrossSliding + = gr_CrossSliding;
    gr.Dragging + = gr_Dragging;
    gr.Holding + = gr_Holding;
    gr.ManipulationCompleted + = gr_ManipulationCompleted;
    gr.ManipulationInertiaStarting + = gr_ManipulationInertiaStarting;
    gr.ManipulationStarted + = gr_ManipulationStarted;
    gr.ManipulationUpdated + = gr_ManipulationUpdated;
    gr.RightTapped + = gr_RightTapped;
    gr.Tapped + = gr_Tapped;
    gr.GestureSettings = Windows.UI.Input.GestureSettings.ManipulationRotate | Windows.UI.Input.GestureSettings.ManipulationTranslateX | Windows.UI.Input.GestureSettings.ManipulationTranslateY |
    Windows.UI.Input.GestureSettings.ManipulationScale | Windows.UI.Input.GestureSettings.ManipulationRotateInertia | Windows.UI.Input.GestureSettings.ManipulationScaleInertia |
    Windows.UI.Input.GestureSettings.ManipulationTranslateInertia | Windows.UI.Input.GestureSettings.Tap;
}无效MainPage_PointerReleased（对象发件人，PointerRoutedEventArgs E）
{
    VAR PS = e.GetIntermediatePoints（NULL）;
    如果（PS =空＆放大器;！＆放大器; ps.Count大于0）
    {
        gr.ProcessUpEvent（PS [0]）;
        e.Handled =真实的;
        gr.CompleteGesture（）;
    }
}无效MainPage_PointerMoved（对象发件人，PointerRoutedEventArgs E）
{
    gr.ProcessMoveEvents（e.GetIntermediatePoints（NULL））;
    e.Handled =真实的;
}虚空MainPage_Pointer pressed（对象发件人，PointerRoutedEventArgs E）
{
    VAR PS = e.GetIntermediatePoints（NULL）;
    如果（PS =空＆放大器;！＆放大器; ps.Count大于0）
    {
        gr.ProcessDownEvent（PS [0]）;
        e.Handled =真实的;
    }
}

按照你需要启用CrossSlide事件将它添加到您的GestureRecongnizer搭好CrossSlideThresholds和方向。从最后一个环节：

example:

Windows.UI.Input.CrossSlideThresholds cst = new Windows.UI.Input.CrossSlideThresholds();
cst.SelectionStart = 2;
cst.SpeedBumpStart = 3;
cst.SpeedBumpEnd = 4;
cst.RearrangeStart = 5;
gr.CrossSlideHorizontally = true;
gr.CrossSlideThresholds = cst;
gr.CrossSliding += gr_CrossSliding;

and make sure it is added to your GestureSettings

gr.GestureSettings = Windows.UI.Input.GestureSettings.ManipulationRotate | Windows.UI.Input.GestureSettings.ManipulationTranslateX |
                     Windows.UI.Input.GestureSettings.ManipulationScale | Windows.UI.Input.GestureSettings.ManipulationRotateInertia |
                     Windows.UI.Input.GestureSettings.ManipulationScaleInertia | Windows.UI.Input.GestureSettings.ManipulationTranslateInertia |
                     Windows.UI.Input.GestureSettings.Tap | Windows.UI.Input.GestureSettings.CrossSlide;
