title: How to apply RatingBar border without using an image?
body: <p>I wanted to create a <code>RatingBar</code> that does not use an image to have a border. But I can't seem to get it right.</p>
  
  <p>Here's what I wanted it to look like:</p>
  
  <p><a href="https://i.stack.imgur.com/68iAg.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/68iAg.png" alt="with border"></a></p>
  
  <p>Here's what I got (filled - half empty - empty):</p>
  
  <p><a href="https://i.stack.imgur.com/nKNjA.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/nKNjA.png" alt="filled - half empty - empty"></a></p>
  
  <p>Here's my layout:</p>
  
  <pre><code>&lt;RatingBar
      android:id="@+id/ratingbar_rate"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_gravity="center"
      android:numStars="5"
      android:rating="2.5"
      android:stepSize="0.5"
      android:scaleX="3.5"
      android:scaleY="3.5"
      style="?android:attr/ratingBarStyleIndicator"
      android:isIndicator="false"
      android:progressTint="@color/star"
      android:progressBackgroundTint="@color/star_border"
      android:secondaryProgressTint="@color/star_partially_empty"
      android:backgroundTint="@color/star_partially_empty"
  /&gt;
  </code></pre>
