Set Toolbar Icon Colour Programmatically
<p>How can I set the colour of icons (home and overflow menu icon) in a <code>Toolbar</code>/<code>AppBarLayout</code> <em>programmatically</em>?</p>

<p>I want to change the toolbar's colour scheme for a single fragment in an activity. Setting the <code>AppBarLayout</code>'s background to a light colour (e.g. light gray with <code>appBarLayout.setBackgroundResource(..);</code>) results in white icons and a white title which are barely visible.</p>

<p>Its layout is as follows:</p>

<pre><code>&lt;android.support.design.widget.AppBarLayout
    android:id="@+id/appbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:fitsSystemWindows="true"&gt;

    &lt;android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:theme="@style/ToolbarStyle"
        app:layout_scrollFlags="scroll|enterAlways"/&gt;

&lt;/android.support.design.widget.AppBarLayout&gt;
</code></pre>
