title: Change RecyclerView scrollBar width
body: <pre><code>    &lt;android.support.v7.widget.RecyclerView
          android:id="@+id/recyclerView"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:background="#ddd"
          android:fadeScrollbars="true"
          android:scrollbarSize="12dp"
          android:orientation="vertical"
          android:scrollbars="vertical"/&gt;
  </code></pre>
  
  <p>I am testing the code on 5.1.1. Changing <code>android:scrollbarSize</code> has no effect. I tried increasing and decreasing it, no change.</p>
  
  <p>How to change the width?</p>
