title: How to pragmatically set/change the color of the Toolbar home icon?
body: <p>I have setup the following <code>AppBarLayout</code> + <code>TabLayout</code> for the main activity of my Android app. </p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;android.support.v4.widget.LinearLayout
      android:id="@+id/main_layout"
      android:orientation="vertical"
      ...&gt;
  
      &lt;android.support.design.widget.AppBarLayout
          android:id="@+id/appbar"
          ...&gt;
  
          &lt;android.support.v7.widget.Toolbar
              android:id="@+id/toolbar"
              ... /&gt;
  
          &lt;android.support.design.widget.TabLayout
              android:id="@+id/tabs"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              app:tabMode="scrollable"
              app:tabGravity="fill"&gt;
  
          &lt;/android.support.design.widget.TabLayout&gt;
      &lt;/android.support.design.widget.AppBarLayout&gt;
  
      ...
  </code></pre>
  
  <p>Basically it looks like this:</p>
  
  <p><a href="https://i.stack.imgur.com/hprqa.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/hprqa.png" alt="enter image description here"></a></p>
  
  <p><strong>The question is:</strong> How can I <strong>pragmatically</strong> change the color of the <strong>home icon</strong> (the hamburger icon in the picture)?</p>
  
  <p>Setting the color within my the XML syltes is no problem:</p>
  
  <pre><code>&lt;style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Light"&gt;
      &lt;item name="android:textColorSecondary"&gt;#ff00ff00&lt;/item&gt;
      ...
  &lt;/style&gt;
  </code></pre>
  
  <p>But how can I change this pragmatically at runtime? There seems to be no setter for textColorSecondary...</p>
