How to set the Color of the item title in navigationDrawer?

Question

I am stuck in my own code. I can't find where to set the color of the "Title" text, in the navigationDrawer, to the defualt gray.

<android.support.design.widget.NavigationView
        android:id="@+id/navigation_view"
        android:background="#000"
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        android:layout_gravity="start"
        app:headerLayout="@layout/header"
        app:itemTextColor="your color"
        app:menu="@menu/drawer" />

app:itemTextColor="your color" only changes each item, like Import, Gallery etc. But how to change the Communicate textColor with the line above?

Picture 2 (dark blue) is what it looks like in my project. I managed to "somewhere" set the color to white in my project.

Can you find my problem? Currently my "Title" text is white..

nav_header_main.xml

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingTop="@dimen/nav_header_vertical_spacing"
        android:src="@android:drawable/sym_def_app_icon"
        />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingTop="@dimen/nav_header_vertical_spacing"
        android:textColor="@color/whiteGray"
        android:text="@string/app_name"
         />


</LinearLayout>

Answer 1

Try :

<item name="android:textColorSecondary">#eeeeee</item>

Edit :

Replace :

 <style name="AppTheme.NoActionBar" parent="@style/Theme.AppCompat">
        <item name="android:windowBackground">@color/darkblue</item>
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>

With This :

<style name="AppTheme.NoActionBar" parent="@style/Theme.AppCompat">
        <item name="android:windowBackground">@color/darkblue</item>
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>

        <item name="android:textColorSecondary">#eeeeee</item>
    </style>

Edit 2 :

  <style name="AppTheme.NoActionBar" parent="@style/Theme.AppCompat">
            <item name="android:windowBackground">@color/darkblue</item>
            <item name="windowActionBar">false</item>
            <item name="windowNoTitle">true</item>

             // change header color       
           <item name="android:textColorSecondary">#eeeeee</item>
            // change separator color
            <item name="android:listDivider">#ff000000</item>
        </style>
