changing title text color and size of menu android

I am developing android application and in my application I am using Sherlock action bar. I am using some menu into my action bar.

<menu xmlns:android="http://schemas.android.com/apk/res/android">

<item android:id="@+id/card_menu"
      android:title="C123" 
      android:showAsAction="always">
    <menu>
        <item android:id="@+id/C0"
              android:title="C0"/>
        <item android:id="@+id/c1"
              android:title="c1" />
        <item android:id="@+id/c2"
              android:title="c2" />
    </menu>
    </item>
<item android:id="@+id/notification"
  android:title="Notifications"
  android:showAsAction="always"
  android:actionLayout="@layout/notification_icon"
  android:icon="@drawable/notification"
  />
<item android:id="@+id/filter"
  android:icon="@drawable/filter"
  android:title="Filter" 
  android:showAsAction="always"
  />

</menu>

and I display this menu into my activity like this..

inflater.inflate(R.menu.menu_type2, menu);

now what I want to do is I want to change my title color of my menu item (c123). I am able to change color of sub menu from style but not able to change of that item text. I tried this in following way.

// this change my sunbmenu text color but I am not able to change color of item text(c123)
<item name="android:dropDownListViewStyle">@style/MyPopupMenu</item>
<item name="dropDownListViewStyle">@style/MyPopupMenu</item>

<style name="MyPopupMenu" parent="Widget.Sherlock.ListPopupWindow">
 <item name="android:textAppearance">@style/TextAppearance.Sherlock.Widget.PopupMenu</item>
 <item name="android:dropDownSelector">@color/white</item>
 <item name="android:dividerHeight">@dimen/divider_height</item>
 <item name="android:divider">@color/maroon</item>

</style>

<style name="TextAppearance.Sherlock.Widget.PopupMenu" parent="android:style/TextAppearance.Holo.Widget.ActionBar.Menu">
 <item name="android:textColor">@color/white</item>
</style>

I want to modify that menu item style change color and size of text and also background of that. How to do that. Need help.. Thank you..

You can change the color of the MenuItem text easily by using SpannableString instead of String.

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.your_menu, menu);

    int positionOfMenuItem = 0; // or whatever...
    MenuItem item = menu.getItem(positionOfMenuItem);
    SpannableString s = new SpannableString("My red MenuItem");
    s.setSpan(new ForegroundColorSpan(Color.RED), 0, s.length(), 0);
    item.setTitle(s);
}
