XNA wp7 gesture detection issue

Question

I have to use both type of input in my app (gestures and simple touch). And i got a problem with it. For example i use double tap gesture and before it detected i have one detection of simple touch. This in not that way i expect, because simple touch has its own logic, which brings me lot of problems. The same issue with Drag, before detecting drag again first decetced simple touch. How can i handle gestures without handling simple touch logic. Here the way im trying to do that:

TouchPanel.EnabledGestures = GestureType.DoubleTap | GestureType.VerticalDrag;
        while (TouchPanel.IsGestureAvailable)
        {
            isGesture = true;
            GestureSample gestureSample = TouchPanel.ReadGesture();
            switch (gestureSample.GestureType)
            {
                case GestureType.DoubleTap:

                    //some logic
                    break;
                case GestureType.HorizontalDrag:
                    //some logic
                    break;
            }
        }


        if (Consts.TouchCollection.Count == 1) 
        {
            var touch = Consts.TouchCollection[0]; //here needed only first touch

            switch (touch.State)
            {
                case TouchLocationState.Pressed:
                     //This one called first if used double tap

                    break;
                case TouchLocatiomState.Moved:
                    //smth
                    break;
                case TouchLocationState.Released:
                    //smth
                    break;
            }
        }

When double tap gesture is used this code calls Pressed -> Released -> DoubleTap -> Pressed I want to handle only double tap case. how to fix this? Feel sorry for my english, hope my question is clear. Any help will be appreciated

Answer 1

To avoid handling the simple touch event after handling the gestures, add a Boolean flag that you set at the beginning of your touch handling to true , lets call it handleSimpleTouch . If you process a gesture, set handleSimpleTouch to false. Then before you process a simple touch, check the valu of handleSimpleTouch , if it's true, then process normally, otherwise, do nothing.

我得出的结论是，唯一可行的方法是不使用TouchPanel.EnabledGestures编写自己的输入。
