title: Use RecyclerView inside ScrollView with flexible Recycler item height
body: <p>I want to know if there is any possible way to use <strong>RecyclerView</strong>?</p>
  
  <p>Before this, I used RecyclerView with <strong>fixed height</strong> inside a <strong>ScrollView</strong> but this time I don't know the height of the item. </p>
  
  <p><strong>Hint</strong>: I read all question and solution on stack question before asking this question.</p>
  
  <p><strong>update:</strong> 
  Some solution show how to scroll <strong>RecyclerView</strong> on its own but I want to show it expanded.</p>
