title: Save to database from multiple Fragments
body: <p>In my Android app i have an Activity with tabs and each tab changes to a different Fragment, each with several fields the user should fill. The user can then submit all data by clicking a button in the action bar.</p>
  
  <p>Is there an easy way to access and store all data from the different Fragments at action bar button click? Am i missing something here?</p>
