Styling the fragments

Many attributes are provided to style the fragments views and theme.

Changing an attribute

You can change attribute in your app's styles.xml

<style name="AppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar">
    <item name="recurrencePickerStyle">@style/RecurrencePickerStyleCustom</item>
</style>

<!-- Recurrence picker theme -->
<style name="RecurrencePickerStyleCustom" parent="RecurrencePickerStyle">
    <!-- You can customize the recurrence picker style here -->
    <!-- This line changes the text appearance of subtitle text views -->
    <item name="rpPickerSubtitleTextAppearance">@style/MySubtitleTextAppearance</item>
</style>

<style name="MySubtitleTextAppearance" parent="RpPickerSubtitleTextAppearance">
    <!-- Don't forget to specify the parent! -->
    <item name="android:allCaps">true</item>
</style>

Parent style name is always the same as the attribute name but starts with a capital letter. It's important to specify the parent, because the parent style might define some attributes that you don't.
