How to remove the title background from a transparent ActionBar?

Question

I'm using a transparent ActionBar with a white title. Unfortunately the title has its own background.

This is my styles.xml:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:windowActionBar">false</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:colorPrimary">@color/app_color</item>
    <item name="android:colorPrimaryDark">#ff077fb1</item>
    <item name="android:colorAccent">@color/app_color</item>
    <item name="android:windowActionModeOverlay">true</item>
    <!-- Support library compatibility -->
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="windowActionBarOverlay">true</item>
    <item name="colorPrimary">@color/app_color</item>
    <item name="colorPrimaryDark">#ff077fb1</item>
    <item name="colorAccent">@color/app_color</item>
    <item name="windowActionModeOverlay">true</item>
</style>
<style name="MyActionBar" parent="Theme.AppCompat.NoActionBar">
    <item name="android:textColorPrimary">@android:color/white</item>
    <item name="android:textColorSecondary">@android:color/white</item>
    <item name="actionMenuTextColor">@android:color/white</item>
    <item name="android:background">@drawable/actionbar_background</item>
    <item name="background">@drawable/actionbar_background</item>
</style>

Here is the toolbar used:

<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:sothree="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:elevation="4dp"
android:minHeight="?attr/actionBarSize"
sothree:theme="@style/MyActionBar">

How can I get rid of that blue title background?

Answer 1

I solved this by removing

<item name="android:background">@drawable/actionbar_background</item>
<item name="background">@drawable/actionbar_background</item>

from styles.xml and adding the background color programatically to the toolbar using

toolbar.setBackgroundColor(myColor);
