How to pragmatically set/change the color of the Toolbar home icon?

Question

I have setup the following AppBarLayout + TabLayout for the main activity of my Android app.

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.LinearLayout
    android:id="@+id/main_layout"
    android:orientation="vertical"
    ...>

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar"
        ...>

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            ... />

        <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">

        </android.support.design.widget.TabLayout>
    </android.support.design.widget.AppBarLayout>

    ...

Basically it looks like this:

The question is: How can I pragmatically change the color of the home icon (the hamburger icon in the picture)?

Setting the color within my the XML syltes is no problem:

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Light">
    <item name="android:textColorSecondary">#ff00ff00</item>
    ...
</style>

But how can I change this pragmatically at runtime? There seems to be no setter for textColorSecondary...

Answer 1

As far as i know, I do not believe you can set the style programatically. What you can do, however, is changing the style ( while keeping the same values) but only changing textColorSecondary value
