XML file:

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

    <item android:top="200px">
        <shape>
            <solid android:color="#6bcbf4" />
        </shape>
    </item>



    <item android:bottom="900px">
        <shape android:shape="oval">
            <solid android:color="#FFF8F8F8"
                />
        </shape>
    </item>



</layer-list>
