title: Toolbar with Gradient Background set title background transparent
body: <p>I defined a Gradient Drawable:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;shape xmlns:android="http://schemas.android.com/apk/res/android"
      android:shape="rectangle" &gt;
  
      &lt;gradient
          android:endColor="#2F3F59"
          android:startColor="#4078A7"
          android:type="linear"
          android:angle="90" /&gt;
  
  &lt;/shape&gt;
  </code></pre>
  
  <p>And I set it on my Toolbar:</p>
  
  <pre><code>&lt;style name="AppTheme.Toolbar" parent="ThemeOverlay.AppCompat.Dark.ActionBar"&gt;
      &lt;item name="android:textColorPrimary"&gt;@color/textcolorsecundary&lt;/item&gt;
      &lt;item name="actionMenuTextColor"&gt;@color/textcolorsecundary&lt;/item&gt;
      &lt;item name="android:textColorSecondary"&gt;@color/textcolorsecundary&lt;/item&gt;
      &lt;item name="android:background"&gt;@drawable/custom_background_blue&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>This is working! <strong>BUT</strong>:</p>

  <p>This is what happens with the title. It gets the same gradient. This looks really ugly so I have to change this. How can I set the background of that info text to be transparent?</p>
