I am trying to design an EditText Field having Shadows (bottom and right side) like this

tried googling & hunted many SO discussions but all are for TextView not EditText.
This is my code adding shadow to Input Text but not to TextField
<EditText android:id="@+id/txtpin" 
        android:maxLength="4" 
        android:layout_marginLeft="10dp" 
        android:layout_height="37dp" 
        android:gravity="center_horizontal" 
        android:inputType="textPassword" 
        android:longClickable="false" 
        android:layout_width="160dp" 
        android:shadowColor="@color/Black"
        android:shadowDx="1.2"
        android:shadowDy="1.2"
        android:shadowRadius="1.5" 
        android:background="@color/White">
            <requestFocus></requestFocus>
        </EditText>
I guess it needs some custom xml view in drawable but not getting exact idea. What will be the logic to achieve this.
Any help would be appreciated.
