wp7 xna手勢不起作用

Question

我想在我的代碼中使用拖動手勢。但不幸的是，它不工作。以下是我正在使用的代碼片段。它有什麼問題嗎？如果是的話，幫助我。

TouchPanel.EnabledGestures = GestureType.DragComplete | GestureType.Tap | GestureType.Pinch | GestureType.FreeDrag; 
while (TouchPanel.IsGestureAvailable) 
{ 
    GestureSample gesture = TouchPanel.ReadGesture(); 

    if (gesture.GestureType == GestureType.DragComplete) 
    { 
     // do something     
    } 
}

TouchPanel.EnabledGestures = GestureType.Tap | GestureType.DragComplete; 
      foreach (GestureSample gestureSample in input.Gestures) 
      { 
       if (gestureSample.GestureType == GestureType.Tap) 
       { 
        Debug.WriteLine("tapped "); 
       } 
       else if (gestureSample.GestureType == GestureType.DragComplete) 
       { 
        Debug.WriteLine("dragged"); 
       } 
      }
