title: Stop Recycleing or Rebinding RecyclerView top header Items
body: <p>I don't want to rebind my top header view items because its contains some graph chart that recalculation not time efficient. Suppose my recycleView is:</p>
  
  <pre><code>ItemTypeHead1
  ItemTypeHead2
  ItemTypeList
  ItemTypeList
  .
  .
  ItemTypeList
  </code></pre>
  
  <p>Normally for doing this I take some boolean value for each of header and in onBindViewHolder check that boolean value. Ex: </p>
  
  <pre><code>if (!isItemTypeHead1Created &amp;&amp; holder instanceof ItemTypeHead1) {
          ((ItemTypeHead1) holder).onBindDataUpdate(Data mData);
          isItemTypeHead1Created = true;
      }
  </code></pre>
  
  <p>So, It don't bind again. But I am looking for any better solution. 
  Please share your idea and let's discuss on it.</p>
  
  <p>Thanks</p>
