Change background color of SearchView button and query

Question

For some reason my searchview has a white background instead of transparent and I cant seem to get rid of it. I am using AppCompat theme. I am using a ToolBar manually as my ActionBar.

menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto">
    <item android:id="@+id/search"
        android:title="Search"
        android:icon="@android:drawable/ic_menu_search"
        app:showAsAction="collapseActionView|ifRoom"
        app:actionViewClass="com.exposure.controls.ExposureSearchView" />
</menu>

<style name="LaunchTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="android:colorBackground">@color/app_background</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:background">@android:color/transparent</item>
        <item name="windowActionBarOverlay">true</item>
        <item name="android:windowActionBarOverlay">true</item>
        <item name="android:windowFullscreen">true</item>
        <item name="windowNoTitle">true</item>
        <item name="windowActionBar">false</item>
        <item name="searchViewStyle">@style/MySearchViewStyle</item>
    </style>

    <style name="MySearchViewStyle" parent="Widget.AppCompat.SearchView">
        <item name="queryBackground">@android:color/transparent</item>
        <item name="submitBackground">@android:color/transparent</item>
    </style>

I updated these backgrounds to transparent and it worked.

<style name="MyActionBar" parent="@style/Widget.AppCompat.Light.ActionBar.Solid">
        <item name="android:background" tools:ignore="NewApi">@android:color/transparent</item>
        <item name="background">@android:color/transparent</item>
