title: Empty RecyclerView on launch
body: <p>I have added a recyclerview on my fragment. So when the app launches there should be no items in this recyclerview. There is also a fab, which opens a alert dialog in this fragment itself. So when the user inputs some text 2 things should happen -</p>
  
  <p>1)The dialog should close AND 1st item of recyclerview should be created.</p>
  
  <p>2)and the user input text should be displayed in this item's textview.(The model for the recyclerview is already created). </p>
