how to create a button with shadow

How to create such button with shadow:
I don't know how to modify this button drawable:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item >
<shape android:shape="rectangle">
<gradient android:angle="90" android:startColor="#0F9D58" android:endColor="#0F9D58" />
<stroke android:width="1dp" android:color="#BABABA" />
<corners android:radius="4dp" />
<padding android:bottom="10dp" android:top="10dp" android:left="20dp" android:right="20dp" />
</shape>
</item>
Thanks!
UPDATE. Finally , the code should be as follows:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list>
<item android:left="5dp" android:right="5dp" android:top="5dp">
<shape>
<corners android:radius="3dp" />
<solid android:color="#0F4858" />
</shape>
</item>
<item android:bottom="2dp" android:left="0dp" android:right="0dp">
<shape>
<gradient android:angle="270"
android:endColor="#0F9D58" android:startColor="#0F9D58" />
<padding android:bottom="10dp" android:left="10dp"
android:right="10dp" android:top="10dp" />
</shape>
</item>
</layer-list>
</item>
</selector>

Read this thread
Basically, you need create a xml for your custom button, like:
button_selector.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list>
<item android:right="5dp" android:top="5dp">
<shape>
<corners android:radius="3dp" />
<solid android:color="#D6D6D6" />
</shape>
</item>
<item android:bottom="2dp" android:left="2dp">
<shape>
<gradient android:angle="270"
android:endColor="#E2E2E2" android:startColor="#BABABA" />
<stroke android:width="1dp" android:color="#BABABA" />
<corners android:radius="4dp" />
<padding android:bottom="10dp" android:left="10dp"
android:right="10dp" android:top="10dp" />
</shape>
</item>
</layer-list>
</item>
And now, you can use it, doing reference to the file with:
<Button
android:background="#drawable/button_selector"
...
..
/>

creating gradient stroke using layer-list

I am trying to use layer-list to create a gradient stroke (i.e. perimeter/border) as the background of my view. But it's not working.
Here is my code
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle" >
<gradient
android:angle="270"
android:centerColor="#FFFFFFFF"
android:endColor="#FFCCCCCC"
android:startColor="#FFCCCCCC"
android:type="linear" />
</shape>
</item>
<item>
<shape android:shape="rectangle" >
<solid android:color="#F0F1F3" />
<margin
android:bottom="4dp"
android:left="4dp"
android:right="4dp"
android:top="4dp" />
</shape>
</item>
</layer-list>
The first item is not visible at all. only the second item fills the screen. Any thoughts on how to fix this?

Maybe this can be of use, it create some shadow effect
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- Drop Shadow Stack -->
<item>
<shape>
<corners android:radius="12dp" />
<padding
android:bottom="1dp"
android:left="1dp"
android:right="1dp"
android:top="1dp" />
<solid android:color="#00CCCCCC" />
</shape>
</item>
<item>
<shape>
<corners android:radius="12dp" />
<padding
android:bottom="1dp"
android:left="1dp"
android:right="1dp"
android:top="1dp" />
<solid android:color="#10CCCCCC" />
</shape>
</item>
<item>
<shape>
<corners android:radius="12dp" />
<padding
android:bottom="1dp"
android:left="1dp"
android:right="1dp"
android:top="1dp" />
<solid android:color="#20CCCCCC" />
</shape>
</item>
<item>
<shape>
<corners android:radius="12dp" />
<padding
android:bottom="1dp"
android:left="1dp"
android:right="1dp"
android:top="1dp" />
<solid android:color="#30CCCCCC" />
</shape>
</item>
<item>
<shape>
<corners android:radius="12dp" />
<padding
android:bottom="1dp"
android:left="1dp"
android:right="1dp"
android:top="1dp" />
<solid android:color="#50CCCCCC" />
</shape>
</item>
<!-- Background -->
<item>
<shape>
<solid android:color="#android:color/black" />
<corners android:radius="12dp" />
</shape>
</item>
</layer-list>

You can try something like this
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape
android:innerRadius="80dp"
android:shape="ring"
android:thickness="20dp"
android:useLevel="false">
<size
android:width="200dp"
android:height="200dp" />
<gradient
android:endColor="#00ff0000"
android:gradientRadius="200"
android:startColor="#ffff0000"
android:type="radial" />
</shape>
</item>
<item
android:bottom="20dp"
android:left="20dp"
android:right="20dp"
android:top="20dp">
<shape android:shape="oval">
<stroke
android:width="1dp"
android:color="#ff0000" />
</shape>
</item>
</layer-list>
