title: How to access variable defined in onCreate in onCreateView
body: <p>I'm trying to access the variable "adapter" declared in the onCreate section in the onCreateView section. It's a List. Every time I check the contents outside the onCreate it's empty.</p>
  
  <p>Here is the code</p>

  <p>When I run it from onBeaconsDiscovered the count is != 0 which is correct. But anywhere else it's always 0.</p>
  
  <p>Is it that I have to use a bundle from inside the same fragment?.</p>
