Customized as per your design, create a drawable file:

 <?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:top="8px">
        <layer-list>
            <item>
                <shape android:shape="rectangle">
                    <solid android:color="#08000000" />
                    <corners android:radius="4dp" />
                    <padding
                        android:bottom="3px"
                        android:left="3px"
                        android:right="3px"
                        android:top="3px" />
                </shape>
            </item>
            <item>
                <shape android:shape="rectangle">
                    <solid android:color="#09000000" />
                    <corners android:radius="4dp" />
