Please help...Thanks in advance.

Your first mistake, shape is not layout bur drawable resource and I'm sure your IDe indicated so much if you check closely.

Here is simple example
res/drawable/form_border_green.xml

<?xml version="1.0" encoding="utf-8"?>

<shape xmlns:android="http://schemas.android.com/apk/res/android"
        android:shape="rectangle">
    <stroke android:color="#00ff00" android:width="2dp"/>
    <padding android:left="15dp" android:top="15dp"
             android:right="15dp" android:bottom="15dp" />
    <corners android:radius="30dp" />
</shape>

res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
        >
    <RelativeLayout
            android:background="@drawable/form_border_green"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:layout_marginBottom="40dp"
            >
        <EditText
                android:id="@+id/email"
