title: How to modify a drawable in a Resource File?
body: <p>I'd like to modify already existing drawable objects in an external resource-file, like:</p>
  
  <pre><code>    &lt;?xml version="1.0" encoding="utf-8"?&gt;
      &lt;resources&gt;
          &lt;drawable name="replyIcon" &gt;
              &lt;!--
              get icon from resources
              set color filter
              ...
              --&gt;
          &lt;/drawable&gt;
      &lt;/resources&gt;
  </code></pre>
  
  <p>Is it possible? Because Android Studio suggests me "drawable" when I input an "&lt;" inside a "&lt; resources>"-file where I can also add style- and color- tags.</p>
