  <p>Hi. In the picture above you can see a back arrow and a (part of) title. I changed the title color using the attached .xml code. But I want to color the back arrow to white too.</p>
  
  <p>I read some answer on the internet, but they look too complicated for such a simple question.</p>
  
  <p>Is the any simple why to do it?</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="false" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>    &lt;android.support.v7.widget.Toolbar
          android:id="@+id/toolbar"
          android:layout_width="fill_parent"
          android:layout_height="?attr/actionBarSize"
          android:background="@color/colorPrimary"
          android:minHeight="?attr/actionBarSize"
          app:titleTextColor="@android:color/white"/&gt;</code></pre>
  </div>
  </div>
  </p>

      protected void onCreate(Bundle savedInstanceState) {
  
          Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
          setSupportActionBar(toolbar);
          ActionBar actionBar = getSupportActionBar();
          actionBar.setDisplayHomeAsUpEnabled(true);
        //...
      }
      //...
  }</code></pre>
  </div>
