title: Recycler View GridLayoutManager - Weights for each row
body: <p>I'm trying to implement a RecyclerView with a GridLayoutManager that accomplishes the following behavior:</p>
  
  <pre><code>  -------------
    |           |
    |           |
    -------------
    |       |   |
    |       |   |
    -------------
    |   |       |
    |   |       |
    -------------
    |       |   |
    |       |   |
    -------------
    |   |       |
    |   |       |
    -------------
  </code></pre>
  
  <p>The idea is that the first item always occupy the full row, then the next rows are divided in 3 spaces, with 2 items, with one item having a weight of 2 and the other a weight of 1 (similar to a LinearLayout).</p>
  
  <p>How can I accomplish such behavior?</p>
