<corners android:radius="5dp" />
</shape></item>
</layer-list></item>
</selector>

If rajan ks' answer does't work, you can try wrapping the button in a CardView (android.support.v7.widget.CardView), and give the CardView some elevation using its app:cardElevation attribute.
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:cardElevation="4dp"
app:cardPreventCornerOverlap="false">
<Button />
</android.support.v7.widget.CardView>

shadow.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>
</selector>
and Add this code to your Button
android:background="#drawable/shadow"
Have a look at this for Material Kind of Shadow: Shadow Background Android

Android selector showing error

In my android xml file I have one edittext .I was trying to customize that edittext the xml is looks like :--
<EditText
android:id="#+id/edi"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ems="10"
android:layout_marginTop="10dp"
android:layout_gravity="center"
android:hint="Username"
android:background="#layout/textbox001"
android:drawableLeft="#drawable/usernameicon"
/ >
and in layout the textbox001 is:--
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<item android:state_pressed="true" >
<shape>
<gradient
android:startColor="#e4e4e2"
android:endColor="#d5d5d5"
android:angle="270" />
<stroke
android:width="0dp"
android:color="#282a2f" />
<corners
android:topLeftRadius="10dp"
android:topRightRadius="10dp"
android:bottomLeftRadius="0dp"
android:bottomRightRadius="0dp" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
</item>
<item>
<shape>
<gradient
android:endColor="#e4e4e2"
android:startColor="#d5d5d5"
android:angle="270"
/>
<stroke
android:width="0dp"
android:color="#282a2f" />
<corners
android:topLeftRadius="10dp"
android:topRightRadius="10dp"
android:bottomLeftRadius="0dp"
android:bottomRightRadius="0dp" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
</item>
</selector>
but its showing errors in selector..i.e:--
element selector does not have required attribute android:layout_width
element selector does not have required attribute android:layout_height
Where is the problem???how can I correct it??
In xml graphic it is also showing that:--
The graphics preview in the layout editor may not be accurate:
Different corner sizes are not supported in Path.addRoundRect. (Ignore for this session)

I think you should place your selector file in drawable folder, not in layout folder !

Its working fine only :
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<item android:state_pressed="true" >
<shape>
<gradient
android:startColor="#e4e4e2"
android:endColor="#d5d5d5"
android:angle="270" />
<stroke
android:width="0dp"
android:color="#282a2f" />
<corners
android:topLeftRadius="10dp"
android:topRightRadius="10dp"
android:bottomLeftRadius="0dp"
android:bottomRightRadius="0dp" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
</item>
<item>

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"
...
..
/>

Simple customized button in android

I've used the tutorial in this link which demonstrates a great way of using different colors for buttons.
He has demonstrated all the colors for the buttons as below
Ex:: for red He mentions as
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" >
<shape>
<solid
android:color="#ef4444" />
<stroke
android:width="1dp"
android:color="#992f2f" />
<corners
android:radius="3dp" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
</item>
<item>
<shape>
<gradient
android:startColor="#ef4444"
android:endColor="#992f2f"
android:angle="270" />
<stroke
android:width="1dp"
android:color="#992f2f" />
<corners
android:radius="3dp" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
</item>
</selector>
But he has not mentioned the color for Orange in the
Can someone give a demonstration with Orange color
Specifications must be same as the ones mentioned for other colors
but color must be orange

Check all color codes here
just replace your desired color in
<item>
<shape>
<gradient
android:startColor="#ef4444"
android:endColor="#992f2f"
android:angle="270" />
<stroke
android:width="1dp"
android:color="#992f2f" />
<corners
android:radius="3dp" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
</item>
These two lines
android:startColor="#ef4444"
android:endColor="#992f2f"
padding is the inside spacing and stroke is the width of boundary of button. just replace the colors in gradient tag and make your desired button.

I just wanted to post the code for answer ( thanks to Brontok & Tanis .7x)
I found the solution::
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" >
<shape>
<solid
android:color="#ff8800" />
<stroke
android:width="1dp"
android:color="#992f2f" />
<corners
android:radius="3dp" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
</item>
<item>
<shape>
<gradient
android:startColor="#ff8800"
android:endColor="#992f2f"
android:angle="270" />
<stroke
android:width="1dp"
android:color="#992f2f" />
<corners
android:radius="3dp" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
</item>
</selector>

Android - How combining Shape drwable and text color different states for button?

I have some troubles managing Android State List for a button. I specified some Shape drwable item for different states, but i also need to change textColor depending on the current state.
My actual state list xml is:
<?xml version="1.0" encoding="utf-8"?>
<selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
<shape>
<gradient
android:startColor="#color/white"
android:endColor="#color/light_gray"
android:angle="270" />
<stroke
android:width="3dp"
android:color="#color/classic_red1" />
<corners
android:radius="3dp" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
</item>
<item>
<shape>
<gradient
android:startColor="#color/classic_red1"
android:endColor="#color/classic_red2"
android:angle="270" />
<stroke
android:width="2dp"
android:color="#color/white" />
<corners
android:radius="3dp" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
</item>
</selector>
