Closed

Description

@Burgov

Did you verify this is a real problem by searching the NativeScript Forum and the other open issues in this repo?

yes

Tell us about the problem

The getX() method of the touch event on a scrollview yields different results in Android vs iOS if the scrollview is scrolled.

Which platform(s) does your issue occur on?

Both

Please provide the following version numbers that your issue occurs with:

See playground app

Please tell us how to recreate the issue in as much detail as possible.

  • scroll the scrollview to have the number 3 in the center of the view
  • tap on the 3
  • a touch handler will register the output of event.getX() on a component property x

example:
in iOS the result is 602.5
in Android the result is 173.05

the difference between the two is exactly equal to scrollView.horizontalOffset.
