React Native - How to get Y Offset Value of a view from ScrollView?

I am trying to get the scroll position of a view. But the value for Y offset to page which is not related to the view's position.

ScrollView Hierarchy:

<ScrollView>
  - MyComponent1
  - MyComponent2
    - SubView1
       - SubView2
         - <View> (Added ref to this view and passing Y offset value through props)
  - MyComponent3
 </ScrollView>

SubView2 Component:

this.myComponent.measure( (fx, fy, width, height, px, py) => {
   console.log('Component width is: ' + width)
   console.log('Component height is: ' + height)
   console.log('X offset to frame: ' + fx)
   console.log('Y offset to frame: ' + fy)
   console.log('X offset to page: ' + px)
   console.log('Y offset to page: ' + py)

   this.props.moveScrollToParticularView(py)
})

<View ref={view => { this.myComponent = view; }}>

I have checked the exact position of a SubView2 view on onScroll method. But did match with the measure value. I can figure it out the measure value is wrong.

Is it ScrollView hierarchy problem?
