Etes-vous en train d'essayer de changer la couleur de textView quand il est pressé? –

Pouvez-vous publier votre code XML auquel le TextView est lié? –

C'est le cas, John. – Kubs

Changer votre sélecteur comme ci-dessous:

<?xml version="1.0" encoding="utf-8"?> 
    <selector xmlns:android="http://schemas.android.com/apk/res/android"> 
     <item android:state_selected="false" android:color="@color/colorAccent" /> 
     <item android:state_selected="true" android:color="@color/colorPrimary" /> 
    </selector>
