Different color for disabled dates CalendarView

I created a custom CalendarView that looks as follows:

enter image description here

I want all of the past days to be in a different color.

My XML is:

<CalendarView
    android:id="@+id/cv_Calendar"
    android:layout_width="match_parent"
    android:layout_height="300dp"
    android:layout_marginStart="16dp"
    android:layout_marginEnd="16dp"
    android:background="@drawable/cv_background"
    android:dateTextAppearance="@style/CalenderViewDateCustomText"
    android:theme="@style/CalenderViewCustom"
    android:weekDayTextAppearance="@style/CalenderViewWeekCustomText"
    app:layout_constraintTop_toBottomOf="@+id/tv_With" />

And my styles are:

<style name="CalenderViewCustom" parent="Theme.AppCompat">
    <item name="colorAccent">@color/colorLightGray</item>
    <item name="colorPrimary">@color/colorLightPurple</item>
    <item name="android:textColorPrimary">@color/colorGrayText</item>
</style>

<style name="CalenderViewDateCustomText" parent="android:TextAppearance.Holo.Small">
    <item name="android:textColor">@color/colorLightPurple</item>
    <item name="android:weekNumberColor">@color/colorLightPurple</item>
</style>

<style name="CalenderViewWeekCustomText" parent="android:TextAppearance.DeviceDefault.Small">
    <item name="android:textColor">@color/colorLightPurple</item>
</style>

I set the minimum date programmatically:

calendarView = findViewById( R.id.cv_Calendar );
calendarView.setMinDate( System.currentTimeMillis() );
calendarView.setOnDateChangeListener( (arg0, year, month, date) -> {
    GregorianCalendar cal = new GregorianCalendar( year, month, date );
    dateInMillis = cal.getTimeInMillis();
} );

Any idea how to change the color?

Thank you

I'm not sure if you still need an answer for this, but in case anyone else comes across this question, here's how you do it:

Basically you need to change the textColor attribute you're using to reference a selector that should look like this:

selectorDateTextColor.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
        
    <!-- The color used by the disabled dates (i.e. everything outside the range you set with minDate and maxDate) -->
    <item android:color="@color/gray" android:state_enabled="false" />
    
    <!-- The color used by everything else -->
    <item android:color="@color/colorLightPurple" />
</selector>

And your style would be:

<style name="CalenderViewDateCustomText" parent="android:TextAppearance.Holo.Small">
    <item name="android:textColor">@color/selectorDateTextColor</item>
    <item name="android:weekNumberColor">@color/colorLightPurple</item>
</style>

You can also add more states such as android:state_activated="true" to change the text color of the date selected by the user.

And if you want to change the color of the circle around the selected date you should add <item name="colorControlActivated">@color/blue</item> to the theme used by your CalendarView.
