Android Question GestureDetector And Scrollview

[alon]

Hi,
I have an app that need to have the ability to let the customer to sign on it.
so i am using the GestureDetector lib.
I create the GestureDetector on a label wich the customer need to sign on it.
the problem is that the label is on a scrollview so when i am trying to sign on the label,
the scrollview is moving and I cannot sign on the label.

Is there a way to disable the scrolling while signing

Thanks...

You can prevent the ScrollView from intercepting touch events. See my answer here: https://www.b4x.com/android/forum/threads/google-maps-vs-custom-list-view-scrolling.73607/

If you aren't able to solve it then please create a small project with the ScrollView and the label and upload it.

Hi Erel,
Sorry but I was not able to solve it.
I also notice that the event lbl_Touch is not working at all.
So I did as you ask , and attached a small app with a lable.

I would have used Reflector.SetOnTouchListener for this.

However the important point is to disable the ScrollView when the touch starts with:

Dim jo As JavaObject = svJobInfo
jo.RunMethod("requestDisallowInterceptTouchEvent", Array(False))

And reenable it when the touch ends in (UP action):

Dim jo As JavaObject = svJobInfo
jo.RunMethod("requestDisallowInterceptTouchEvent", Array(True))

Sorry but still not working for me.
I tries to put it in the Gesture_onPointerDown and Gesture_onPointerUp
I also tried to use Reflector and it is not working.

What am i missing here?

Try this!

Sub Gesture_onTouch(Action As Int, X As Float, Y As Float, MotionEvent As Object) As Boolean
    If Action=GD.ACTION_DOWN Then
        Dim jo As JavaObject = SV
        jo.RunMethod("requestDisallowInterceptTouchEvent", Array(True))       
    Else If Action = GD.ACTION_UP Then
        Dim jo As JavaObject = SV
        jo.RunMethod("requestDisallowInterceptTouchEvent", Array(False))
        'Removes the first painter from the list
        Gesture_onPointerUp(0, 0, MotionEvent)
    End If
    Return True
End Sub

Because I'm looking for examples

I don't know if the landlord has solved this problem. This is my solution, so I sent it out to everyone for reference

You should have created new thread for this to puplish. Posting to old threads is a mistake.

Nostalgia.
And in any case, before answering a question, you need to think carefully in order to give correct advice.
