似乎无法摆脱的TouchPanel触摸输入的Windows Phone 7 [英] Can't seem to get touch input from TouchPanel in Windows Phone 7

问题描述

我已经开始在Visual Studio中一个新的项目，并已试图用静态的TouchPanel类来获得输入。我已经启用通过EnabledGestures属性'点击'的姿态，但是当我点击屏幕手势不登记（即TouchPanel.IsGestureAvailable返回false）。

I've started a new project in Visual Studio and have been trying to use the static TouchPanel class to get input. I have enabled the 'Tap' gesture through the EnabledGestures property, however when I tap the screen the gesture does not register (i.e. TouchPanel.IsGestureAvailable returns false).

其他的事情如Mouse.GetState（）。LeftButton == ButtonState.Pressed永远不要证明是正确的，即使在我以前的项目（这是基于微软样本项目），它总是工作没有任何问题。

Other things such as Mouse.GetState().LeftButton == ButtonState.Pressed do not ever prove true even though in my previous project (which was based on a Microsoft sample project) it always worked without any problems.

任何人有任何想法，为什么我不能似乎能够从设备得到任何形式的输入？

Anyone have any ideas why I can't seem to be able to get any form of input from the device?

推荐答案

下面是我如何设置它 - 在页面构造函数中我设置的动作类型：

Here is how I set it up - in the page constructor I set the gesture type:

// Constructor
public MainPage()
{
    InitializeComponent();
    TouchPanel.EnabledGestures = GestureType.Tap;
}

然后，在XAML标记为格主我把它链接到一个在ManipulationCompleted事件处理程序：

Then, in the XAML markup for the main grid I link it to a ManipulationCompleted event handler:

<Grid ManipulationCompleted="LayoutRoot_ManipulationCompleted" x:Name="LayoutRoot" Background="Transparent">
</Grid>

然后，在相同的事件处理程序：

Then, in the same event handler:

private void LayoutRoot_ManipulationCompleted(object sender, ManipulationCompletedEventArgs e)
{
    if (TouchPanel.IsGestureAvailable)
    {
        if (TouchPanel.ReadGesture().GestureType == GestureType.Tap)
        {
            Debug.WriteLine("A");
        }
    }
}

在Silverlight对我的作品项目。在XNA，你必须还添加了手势类型的构造器：

Works for me in a Silverlight project. In XNA, you would have to add the gesture types also in the constructor:

public Game1()
{
    graphics = new GraphicsDeviceManager(this);

    TargetElapsedTime = TimeSpan.FromTicks(333333);
    TouchPanel.EnabledGestures = GestureType.Tap;
}

然后在Update方法你有相同的验证b
$ b

Then in the Update method you have the same verification:

protected override void Update(GameTime gameTime)
{
    // Allows the game to exit
    if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
        this.Exit();

    if (TouchPanel.IsGestureAvailable)
    {
        if (TouchPanel.ReadGesture().GestureType == GestureType.Tap)
        {
            Debug.WriteLine("A");
        }
    }

    // TODO: Add your update logic here

    base.Update(gameTime);
}
