xmlversion="1.0"encoding="UTF-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">

            <solidandroid:color="#FFFFFF"/>
            <cornersandroid:radius="5dip"/>

         <padding
              android:left="10dp"
              android:top="10dp"
              android:right="10dp"
              android:bottom="10dp"
          />
shape>

main.xml
