Android - How combining Shape drwable and text color different states for button?

I have some troubles managing Android State List for a button. I specified some Shape drwable item for different states, but i also need to change textColor depending on the current state.

My actual state list xml is:

<?xml version="1.0" encoding="utf-8"?>    
<selector
    xmlns:android="http://schemas.android.com/apk/res/android">
 <item android:state_pressed="true">
        <shape>
            <gradient
                android:startColor="@color/white"
                android:endColor="@color/light_gray"
                android:angle="270" />
            <stroke
                android:width="3dp"
                android:color="@color/classic_red1" />
            <corners
                android:radius="3dp" />
            <padding
                android:left="10dp"
                android:top="10dp"
                android:right="10dp"
                android:bottom="10dp" />

    <item>
        <shape>
            <gradient
                android:startColor="@color/classic_red1"
                android:endColor="@color/classic_red2"
                android:angle="270" />
            <stroke
                android:width="2dp"
                android:color="@color/white" />
            <corners
                android:radius="3dp" />
            <padding
                android:left="10dp"
                android:top="10dp"
                android:right="10dp"
                android:bottom="10dp" />
        </shape>
    </item>
</selector>

            android:endColor="@color/light_gray"
            android:angle="270" />
        <stroke
            android:width="3dp"
