Change color of ToolBarItem in XAML

问题:

I've added a toolbaritem in my app, however i dont see a way to change its background and text color.

<ContentPage.ToolbarItems>

    <ToolbarItem Text="About" 
                 Icon="ic_action_more_vert.png"
                 Priority="0"
                 Order="Secondary"
                 Clicked="ToolbarItem_Clicked"/>

    <ToolbarItem Text="Settings"
                 Icon="ic_action_more_vert.png"
                 Priority="0"
                 Order="Secondary"/>

</ContentPage.ToolbarItems>

This is what I'd like changed. The black menu with white text, want to change that bg color and text color. Any idea how to achieve this?

As @Gerald Versluis suggested, you can do this by Android styling.

Firstly you can find the styles.xml file under the values folder of Resources in Android project:

Inside of this file, you can open this file and create a style for your menu like this:

<style name="AppToolbarTheme" parent="Theme.AppCompat.NoActionBar">
  <item name="android:colorBackground">#2196F3</item>
  <item name="android:textColor">#000080</item>
</style>

Then open the Toolbar.axml in android project

and change the app:popupTheme of Toolbar like this:

app:popupTheme="@style/AppToolbarTheme"

Update:

Here is the code of Toolbar:

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:minHeight="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    app:popupTheme="@style/AppToolbarTheme" />

I found a solution :https://forums.xamarin.com/discussion/40529/toolbaritem-textcolor

Simple add to "styles.xml":

<item name="android:actionMenuTextColor"> @color/orange </item>

I've spent hours looking for it..
