it can be achieved in you activity class.
1) get the reference of CustomHorizontalView
2) then it's child view.
3) in onWindowFoucs get width of CustomHorizotalView and child view.
4) and calculate the proportion of result value of above width and
horizontal length of scroll.
5) pass the resultant value to seek bar.
