Programmatically pass (or delay) touch event to panel...?

I am working on an app with a custom GUI, controlled with multi-touches via the Gestures library. I have a three finger swipe gesture to scroll through screens.

On one screen I have standard UI elements, at the moment ListViews.

My issue is that I want to be able to delay passing touch events through to the panel containing the ListView.

ie when a touch is made on the panel containing the ListViews I need to be able to wait until I am sure that the first touch is not part of a multi-touch gesture, and only then allow it to pass to the ListView.

Any ideas would be much appreciated...

Dim r As Reflector
r.Target = your_listview
r.RunMethod2("requestDisallowInterceptTouchEvent", True, "java.lang.boolean")

Would creating a MotionEvent object be possible with the Reflection library?

Sub GD_onTouch(Action As Int, X As Float, Y As Float, MotionEvent As Object)
   Dim r As Reflector
   r.Target = your_view
   r.RunMethod4("onTouchEvent", Array As Object(MotionEvent), Array As String("android.view.MotionEvent"))
End Sub

I will answer for my own library because I know it well, of course. So, with Gesture Detector (but I think that works also with Gestures), you can pass a MotionEvent to another view this way:

B4X:

Sub GD_onTouch(Action As Int, X As Float, Y As Float, MotionEvent As Object)
   Dim r As Reflector
   r.Target = your_view
   r.RunMethod4("onTouchEvent", Array As Object(MotionEvent), Array As String("android.view.MotionEvent"))
End Sub

Beware: the X and Y positions, included in the MotionEvent data, are relatives to the top left corner of the view that first receives the event. So, if your destination view has a different size, you'll get shifted positions.

Is there a way to use this method to temporarily prevent a ScrollView from scrolling?
