I have a fragment with RecyclerView attached with the LinearSnapHelper so to get the view in the center and highlight it by scaling its size.

it is working fine , but when pop this fragment from backstack on back press, it throws following exception.

E/UncaughtException: java.lang.IllegalStateException: View with id 2131689939: android.support.v7.widget.RecyclerView#onMeasure() did not set the measured dimension by calling setMeasuredDimension()

I solved this by simply calling mRecyclerView.setLayoutManager(new LinearLayoutManager(this)); and it worked, I hope it'll help somebody.

Okay, I just fixed it as @Kevin Robatel mentioned. In my case, I was initializing the layout manager only once in the onCreate(), then using it onViewCreated() or onResume()(i.e, in multiple places).

So, the fix is "re-initialize the layout manager everytime you need to set the layout manager".

It's a lessen for me too, cheers!

In my case i have more than 1 recycler view but i create linearlayout manager only once.

i create linearlayout manager for each recycler view and it worked.
