title: Set the tint of an ImageView using databinding
body: <p>I use databinding to set the tint of my <code>ImageView</code>. And this is working well :</p>
  <pre><code>android:tint=&quot;@{plantEntity.isFavorite ? @color/favorite : @color/favorite_none}&quot; /&gt;
  </code></pre>
  <p>The problem is <code>android:tint</code> is deprecated. When I try to use <code>app:tint</code> instead, I have this error :</p>
  <blockquote>
  <pre><code>Cannot find a setter for &lt;android.widget.ImageView app:color&gt; that accepts parameter type 'int'
  
  If a binding adapter provides the setter, check that the adapter is annotated correctly and that the parameter type matches.
  </code></pre>
  </blockquote>
  <p>Why and what I have to do ? Create a <code>BindingAdapter</code> ?</p>
