title: Android Firestore, Click on Collection to Display Documents
body: <p>I'm wondering is it possible to display the Collections in a List, add a listener to each list item, then when the user clicks a list item (the collection name), that then points to the corresponding documents, and a list can be generated of all the documents. </p>
  
  <p>For Example: The list display all Collections, If the user clicked "Roscommon" the list would then display "Forest Park, Rockfield" and the same again when the user picked one it would display the details. </p>
