In android studio there is in build drawable that you can use for apply shadow to any View. That is similar like a drop shadow.

android:background="@drawable/abc_menu_dropdown_panel_holo_light"

Using this you can not change the background color of the view & its border color. If you want your own custom drawable then use layer-list

custom_drop_shadow_drawable.xml

<?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android">    <!--the shadow comes from here-->    <item        android:bottom="0dp"        android:drawable="@android:drawable/dialog_holo_light_frame"        android:left="0dp"        android:right="0dp"        android:top="0dp">    </item>    <item        android:bottom="0dp"        android:left="0dp"        android:right="0dp"        android:top="0dp">        <!--whatever you want in the background, here i preferred solid white -->        <shape android:shape="rectangle">            <solid android:color="@android:color/red" />        </shape>    </item> </layer-list>

and apply to your view like below

android:background="@drawable/custom_drop_shadow_drawable"
