how to hide Fragment element from another fragment in Android - issue android

I wanted to hide component of a Fragment from another Fragment. I am using ViewPager for  Fragments. previously I transfer data from one Fragment to another Fragment, that time I before FragmentTransaction replace I added Bundle to ListDetailsFragment. so that was pretty easy stuff. i use FrameLayout Fragments. And it this case ViewPager is in place.

I was able to pass data to Activity with interface, but unable to update date as fragment is already created. looking Fragment life cycle I was hopeful that onStart() will help me to update data when that particular Fragment is displayed. But I was wrong due to ViewPager  in place. than I have my answer in https://stackoverflow.com/questions/18375288/fragment-lifecycle-which-method-is-called-upon-show-hide.

Here is the solution code I am come out with.

[Objective selecting Hide / Show radio button in FragmentOne, I will Hide / Show text in FragmentTwo]
