I am getting error while setting up custom views for tabs in tab layout. Every tab runs fine on the first run, but when I swipe between tabs, runtime error appears. I am just trying out tab layout for the first time, can somebody help me with this ?

The answer is simple : don't use xml fragments at all. It is bad supported, has a lot of limitations, like that with which you met.
The problem is that two same xml fragments ( without workarounds) couldn't exist together, because them share same fragment id. The crash happends when history fragment tried to recreate it's view, due to page changing process, but previous one still hadn't been garbage collected.
Sure, you still could setOffscreenPageLimit on ViewPager to 2 in your case ( all views will stay in memory) , but you should just remove you xml fragment and attach it programmatically if really needed.
