GestureService OnFlick [英] GestureService OnFlick

问题描述

如何在代码隐藏（即不在XAML中）中添加GestureService和Flick事件的处理程序？

How can I add the GestureService and a handler for the Flick event in code-behind (i.e. not in XAML)?

推荐答案

首先，请确保您已经添加了对用于Windows Phone 7的Silverlight工具包（特别是Microsoft）的引用。 Phone.Controls.Toolkit.dll程序集。然后确保您具有Microsoft.Phone.Controls命名空间的XML命名空间引用：

Firstly, make sure you've added a reference to the Silverlight Toolkit for Windows Phone 7, specifically the Microsoft.Phone.Controls.Toolkit.dll assembly. Then make sure you have an XML namespace reference for the Microsoft.Phone.Controls namespace:

xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"

然后，添加 GestureService.GestureListener 到要在其上处理手势的控件：

Then, add the GestureService.GestureListener to the control you want to handle gestures on:

<TextBlock x:Name="test" Text="Test">
    <toolkit:GestureService.GestureListener>
        <toolkit:GestureListener Flick="TextBlock_Flick" />
    </toolkit:GestureService.GestureListener>
</TextBlock>

然后，您只需要在事件处理程序中实现逻辑即可。

Then you just need to implement your logic in the event handler.

更新：以上方法用于在XAML中使用 GestureService ；要在代码后面使用 GestureService ，请使用 GetGestureListener 方法：

Update: The above approach is for using the GestureService in XAML; to use the GestureService in code-behind you use the GetGestureListener method:

var listener = GestureService.GetGestureListener(this.test);
listener.Flick += this.TextBlock_Flick;
