How to add a drop shadow to a Rectangular Shape in Android

Question

I am developing an Android App in which I need to use a Rectangular shape which should have a drop_shadow. I have designed a rectangular shape but somehow i am not able to add a drop shadow to it on (right and left sides). PS: this rectangular shape is added as a background attribute.

Try this:

    <?xml version="1.0" encoding="utf-8"?>
    <layer-list    
        xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <solid android:color="#CABBBBBB"/>
            <corners android:radius="2dp" />
        </shape>
    </item>

    <item
        android:left="0dp"
        android:right="1dp"
        android:top="0dp"
        android:bottom="2dp">

        <shape android:shape="rectangle">
            <solid android:color="@android:color/white"/>
            <corners android:radius="1dp" />
        </shape>
   </item>
</layer-list>
