I'm trying to figure out how to change the background and text colors of the dialog box that shows when you tap a date or time picker. This is in a Xamarin forms project, specifically the android app. Those properties are not exposed anywhere in the DatePicker control or the renderer that I can find... currently it shows up as this bright pink... thanks!

Add item : "android:datePickerDialogTheme" in your style.xml

<item name="android:datePickerDialogTheme">@style/AppCompatDialogStyle</item>

<style name="AppCompatDialogStyle" parent="Theme.AppCompat.Light.Dialog">
        <item name="colorAccent">#2196F3</item>
    </style>

Complete style.xml

    <?xml version="1.0" encoding="UTF-8"?>
<resources>
    <style name="MyTheme" parent="MyTheme.Base">
    </style>
    <!-- Base theme applied no matter what API -->
    <style name="MyTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
        <!--If you are using revision 22.1 please use just windowNoTitle. Without android:-->
        <item name="windowNoTitle">true</item>
        <!--We will be using the toolbar so no need to show ActionBar-->
        <item name="windowActionBar">false</item>
        <!-- Set theme colors from http://www.google.com/design/spec/style/color.html#color-color-palette-->
        <!-- colorPrimary is used for the default action bar background -->
        <item name="colorPrimary">#2196F3</item>
        <!-- colorPrimaryDark is used for the status bar -->
        <item name="colorPrimaryDark">#2196F3</item>
        <!-- colorAccent is used as the default value for colorControlActivated
         which is used to tint widgets -->
        <item name="colorAccent">#2196F3</item>
        <!-- You can also set colorControlNormal, colorControlActivated
         colorControlHighlight and colorSwitchThumbNormal. -->
        <item name="windowActionModeOverlay">true</item>
        <item name="android:datePickerDialogTheme">@style/AppCompatDialogStyle</item>
    </style>
    <style name="AppCompatDialogStyle" parent="Theme.AppCompat.Light.Dialog">
        <item name="colorAccent">#2196F3</item>
    </style>
    <style name="MyDatePickerStyle" parent="@android:style/Widget.Material.Light.DatePicker">
        <item name="android:headerBackground">#2196F3</item>
    </style>
    <style name="MyDatePickerDialogTheme" parent="android:Theme.Material.Light.Dialog">
