  <p>How can I change the navigation bar color?
  I would like to use a white style.</p>

  <hr>
  
  <p>Edit: In my resources, I tested the style:</p>
  
  <pre><code>&lt;item name="android:navigationBarColor" tools:targetApi="21"&gt;@android:color/white&lt;/item&gt;
  </code></pre>
  
  <p>But the buttons are white. I would like the same renderer as the second image.</p>
