use shape resources
like

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">

    <solid android:color="@color/red" />
    <size
        android:width="40dp"
        android:height="40dp" />
</shape>

app:calendarBackground="@drawable/red"

Thank you !!! I have tried to change background color of calendar using drawable resource. It was working when a calendar is on month mode. When I scroll to week mode the background color not working.

@kalaiarasisp I see your screenshot is the custom Adapter pattern，Custom property is invalid when in custom Adapter pattern ，You can try to change background color of calendar using drawable resource in "TestMiui10Activity"
