Add shadow to custom shape on Android

Question

Is it possible to add a drop shadow to a custom shape in Android? After looking through the documentation, I only see a way to apply a text shadow.

I've tried this with no luck:

<?xml version="1.0" encoding="UTF-8"?> 
   <shape xmlns:android="http://schemas.android.com/apk/res/android" 
   android:shape="rectangle"> 
     <solid android:color="#90ffffff"/>
       <corners android:radius="12dp" />
     <item name="android:shadowColor">#000000</item> 
     <item name="android:shadowRadius">5</item> 
     <item name="android:shadowDy">3</item> 
   </shape>

Answer 1

After Lots of search finally I got this

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

<!-- Bottom 2dp Shadow -->
<item>
    <shape  android:shape="rectangle">

        <solid android:color="#d8d8d8" />
        <corners android:radius="7dp" />

    </shape>
</item>

<!-- White Top color -->
<item android:bottom="3px">

    <shape  android:shape="rectangle">

    <solid android:color="#FFFFFF" />
    <corners android:radius="7dp" />


    </shape>

</item>


</layer-list>
