更改导航抽屉中菜单标题标题项的文本颜色

Question

I'm trying to implement dark mode in my application. I've implemented on menu item. It is changing the color but what I want is to change the color of heading as well because when dark mode is implemented the heading menu is hidden as the color is light grey.

Navigation Menu:

   <android.support.design.widget.NavigationView
    android:id="@+id/navigation"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:background="?attr/bgColor"
    app:itemTextColor="?attr/textColor"
    app:headerLayout="@layout/nav_header_home"
    app:menu="@menu/nav_items" />

Answer 1

Add <item name="android:textColorSecondary">@color/white</item> inside your AppTheme and AppTheme.NoActionBar styles.xml file like this:

<resources>
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>

        <item name="android:textColorSecondary">@color/white</item>
    </style>

    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>

        <item name="android:textColorSecondary">@color/white</item>
    </style>
...
</resources>

where the color value <color name="white">#FFFFFF</color> is placed in colors.xml .

The result looks exactly like you wanted:
