Try this,

ziehbar/navigation_text_color:

<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <!-- This is used when the Navigation Item is checked --> 
    <item android:color="#009688" android:state_checked="true" /> 
    <!-- This is the default text color --> 
    <item android:color="#E91E63" /> 
</selector> 

und Layout:

<android.support.design.widget.NavigationView 
     . 
     . 
     app:itemTextColor="@drawable/navigation_text_color"/>
