title: Get position of 'x' item in RecyclerView
body: <p>How to get x/y of an item of a recycler view. 
  mRecyclerView.getChildAt(1) gives the child visible at position 1.
  I want to get the list child at 1st position to perform some operation when it reaches 0,0.</p>
  
  <pre><code>if(mRecyclerView.getChildAt(1).getTop() == 0){
  
  //do some operation
  
  }
  </code></pre>
