title: How to use tools:context to associtate Fragment files?
body: <p>Recently I came across the use-case of using <code>tools:context</code> in my layout files for activities.
  I learned that I can use it to associate an Activity class file to my layout file.</p>
  
  <p>But how can I use it to associate a Fragment class file to any layout?</p>
  
  <p>Bacuase as I have tried, it is only showing Activity list in autocomplete suggestion.</p>
