title: rxJava how to fetch data from sqlite and showing in recycler view
body: <p>Recently started using <code>rxJava</code> in one of my projects. There are several demoes out there showcasing the use of <code>retrofit</code> and its observables for display but can somebody show an example of doing this with our own database. </p>
  
  <p>I tried it myself ref: <a href="https://stackoverflow.com/questions/38984241/rxjava-observer-onnext-not-called-second-time?noredirect=1#comment65334872_38984241">this question</a></p>
  
  <p>But am unable to think of a way to properly combine all the generated object <code>observables</code> into a list that can be updated inside the adapter in one go. <code>toList</code> seems to terminate the <code>observable</code> after the first run, thus can't be used directly.</p>
  
  <p>Thanks! </p>
