title: Save Fragment View when popbackstack from Fragment B to A (like. finish in activity)
body: <p>I have two fragments <strong>FRAGMENT A</strong> and <strong>FRAGMENT B</strong>. WhenI go from <strong>FRAGMENT A</strong> to <strong>FRAGMENT B</strong> I am adding <strong>FRAGMENT A</strong> in backstack using <code>addtobackstack(null)</code> and also using <code>replace()</code> method. The problem is when I call <code>popbackstack()</code> from <strong>FRAGMENT B</strong> --> <strong>FRAGMENT A</strong> then <code>OnCreateView()</code> and <code>onViewCreated()</code> calls again and It loads the recycler view again in <strong>FRAGMENT A</strong>. I know all the instance are not loaded again 
  but the problem is I do not want to load view again. Ex. in activity when i call finish previous activity remain same as we left.</p>
  
  <p><strong>NOTE</strong> : I don't want to use <code>add()</code> method in <code>beginTransaction</code> because it overlap other fragment. </p>
  
  <p>Thanks     </p>
