Add drop shadow effects to EditText Field

问题:

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.

Well.. @Shalini's answer helped me in this way but still I got another way to achieve 2D shadow with EditText Field and I am going to share with you.

We need to create custom XML view with three layer for EditText, bottom shadow and right side shadow

Below is my code.

res/drawable/edittext_shadow.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

<!-- most important is order of layers -->

    <!-- Bottom right side 2dp Shadow -->
    <item >
        <shape android:shape="rectangle">
            <solid android:color="#000000" />           
        </shape>
    </item>

    <!-- Bottom 2dp Shadow -->
    <item>
        <shape android:shape="rectangle">
            <solid android:color="#000000" />   
        </shape>
    </item>

    <!-- White Top color -->
    <item android:bottom="3px" android:right="3px">
        <shape android:shape="rectangle">
            <solid android:color="#FFFFFF" />           
        </shape>
    </item> 
</layer-list>

Now we can set this shadow view to our TextField using "Background" property

like this

res/layout/main.xml

<EditText android:layout_width="wrap_content" 
            android:id="@+id/txtpin"  
            android:maxLength="4" 
            android:layout_height="37dp" 
            android:gravity="center_horizontal" 
            android:longClickable="false" 
            android:padding="2dp"

            android:inputType="textPassword|number" 
            android:password="true" 
            android:background="@drawable/edittext_shadow" 
            android:layout_weight="0.98" 
            android:layout_marginLeft="15dp">
                <requestFocus></requestFocus>
   </EditText>

---

and the result screen is like I have posted in question above.

Thanks to SO, sharing knowledge.

This works for me..

   <EditText 
       android:layout_width="fill_parent" 
       android:shadowRadius="2"  
       android:shadowColor="#0000ff"
       android:shadowDx="2"
       android:shadowDy="4" 
       android:id="@+id/EditText01" 
       android:layout_height="wrap_content" />

Hope it helps:)

From Shadow Effect for a Text in Android?, perhaps you'd consider using

android:shadowColor, 
android:shadowDx,
android:shadowDy,
android:shadowRadius;

Alternatively:

setShadowLayer()
