v_required field to be dynamically configured based on other view types

[aurangzaibumer]

I have one spinner and one edit text field
in spinner i have two options
if user selects an option A from spinner - the required should be set true for edit text field (user has to enter data into edit text field)
if user selects an option B from spinner - the required should be set false for edit text field (user may skip entering data into edit text field)

is this possible?

Thanks
