Android Question Change tabstrip height

[Pooya1]

The first question with many information
I use TabStrip in B4a
There is no problem in use this good library
But Suppose :
I add TabStrip in layout and load layout in Activity
After loadlayout,i add Scrollview intro TabStrip and add many item to Scrollview
Ok
Now i run app and it is working good and i can change page and scroll the list
There is no any problem so far
Now i like to when user scroll Scrollview to bottom,The tabs of TabStrib move to the top (Move from 0 Position to -40dip) and hide tabs
And when scroll to top of list,tabs move to main position (Move from -40dip to 0) and user can see tabs
And i dont have problem so far
My problem is height if TabStrip
When i move tabs to the top,My Tabstrip is smaller than last and i need add 40dip height to TabStrip
But i dont know how do change height of TabStrib programmatically
Is it necessary my information about question?

Sounds to me that it will be simpler to create the TabStrip with the larger height and only change the ScrollView height.
