title: How to make a smaller RatingBar?
body: <p>I've added a <strong>RatingBar</strong> in a layout:</p>
  
  <pre><code>&lt;RatingBar 
      android:id="@+id/ratingbar"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:numStars="5"
      android:stepSize="1.0"
      /&gt;  
  </code></pre>
  
  <p>But the default style for the rating bar is too large.<br>
  I've try to change it by adding the android style : <code>style="?android:attr/ratingBarStyleSmall"</code></p>
  
  <p>But the result is too small and it's impossible to set a rate with this property.</p>
  
  <p>How could I do?</p>
