Path way from Values to XML in android studio

I'm trying to find the pathway from the XML folder in Android Studio to the Values folder which holds my list-array that I'm going to enter as the "entries" array, but I can't seem to figure it out, please help!

    <ListPreference
    android:title="Units"
    android:defaultValue=""
    android:entries=""
    android:summary=""
    ></ListPreference>
