title: Communicate between Recyclerviews in Fragments (ViewPager)
body: <p>i have 3 Fragments which i access with Horizontal Swiping (ViewPager). In each Fragment is a recyclerview (source, translation and description). Now i have implemented code to enable selecting items in the recyclerview. What i would love now is,that when i click on an item in the first recylcerview, an item in the second and third recylcerview also get selected. 
  Do I need to go over the activity that starts the fragments, or what would be the recommended method to do this. I dont need code, just the best possible way to do this...</p>
  
  <p>thanks very much</p>
