我尝试更改项目导航视图菜单的颜色:

styles.xml

<item name="android:activatedBackgroundIndicator">@drawable/activated_background</item>

activated_background.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@color/White" />
    <item android:state_focused="true" android:drawable="@color/White" />
    <item android:state_activated="true" android:drawable="@color/White" />
    <item android:drawable="@android:color/transparent" />
</selector>

drawer.xml:

<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android">

<group
    android:id="@+id/group_1">
    <item
        android:id="@+id/drawer_menu_account"
        android:checked="false"
        android:title="@string/menu_account"
        android:icon="@drawable/ic_account_grey600_24dp" />
    <item
        android:id="@+id/drawer_menu_my_post"
        android:checked="false"
        android:title="@string/menu_my_post"
        android:icon="@drawable/ic_pin_grey600_24dp" />
</group>
[...]

背景颜色不改变..我做错了什么？
