I am tring below code for make shape look like below image, is that possible to make below screenshot by only layer-list concept?
What i hv tried ?
This is my code :
<item>
<shape android:shape="rectangle" >
<solid android:color="#00f" />
<padding android:bottom="2dp" />
</shape>
</item>
<item android:bottom="10dp">
<shape android:shape="rectangle" >
<solid android:color="#fff" />
<padding
android:left="2dp"
android:right="2dp" />
</shape>
</item>
<item>
<shape android:shape="rectangle" >
<solid android:color="#fff" />
</shape>
</item>
<item>
<shape>
<!-- set the shadow color here -->
<stroke
android:width="2dp"
android:color="#color/generic_shadow_color" />
<!-- setting the thickness of shadow (positive value will give shadow on that side) -->
<padding
android:bottom="2dp"
android:left="-1dp"
android:right="2dp"
android:top="-1dp" />
<corners android:radius="7dp" />
</shape>
</item>
<!-- Background -->
<item>
<shape>
<solid android:color="#color/generic_shadow_color" />
<corners android:radius="7dp" />
</shape>
</item>
Result Shape i want is :

I have a button and a selector that must change color, padding and corner radius of the button. I have no problems with changing the color, but I can never see any changes with padding and corner radius.
button_color.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/button_disabled" android:state_enabled="false">
<shape
android:shape="rectangle"
android:padding="8dp">
<corners android:radius="4dp" />
</shape>
</item>
<item android:drawable="#color/button_pressed" android:state_pressed="true">
<shape
android:shape="rectangle"
android:padding="8dp">
<corners android:radius="4dp" />
</shape>
</item>
<item android:drawable="#color/button_focused" android:state_focused="true">
<shape
android:shape="rectangle"
android:padding="8dp">
<corners android:radius="4dp" />
</shape>
</item>
<item android:drawable="#color/colorAccent">
<shape
android:shape="rectangle"
android:padding="8dp">
<corners android:radius="4dp" />
</shape>
</item>
</selector>
code of the button:
<LinearLayout>
....
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/add_to_fav"
android:id="#+id/add"
android:background="#drawable/button_color"
android:textColor="#drawable/button_text_color" />
</LinearLayout>
I know some clumsy way to get the padding - put it into the layout, but 1) it would be "useless parent"; 2) I wouldn't get corner radius.
So what am I doing wrong so I have not shape?
Thanks!
Padding, color and corners should be inside shape
So try this:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false">
<shape>
<padding android:left="5dp" android:top="2dp"
android:right="5dp" android:bottom="2dp" />
<corners android:radius="4dp" />
<solid android:color="#color/colorPrimary"/>
</shape>
</item>
<item android:state_pressed="true">
<shape>
<padding android:left="5dp" android:top="2dp"
android:right="5dp" android:bottom="2dp" />
<corners android:radius="4dp" />
<solid android:color="#color/colorAccent"/>
</shape>
</item>
<item android:state_focused="true">
<shape>
<padding android:left="5dp" android:top="2dp"
android:right="5dp" android:bottom="2dp" />
<corners android:radius="4dp" />
<solid android:color="#color/colorPrimary"/>
</shape>
</item>
<item>
<shape>
<padding android:left="5dp" android:top="2dp"
android:right="5dp" android:bottom="2dp" />
<solid android:color="#color/colorPrimaryDark"/>
<corners android:radius="4dp" />
</shape>
</item>
</selector>
This way all of them will work.
The android:radius value was probly just too small for the effect to be visible. The syntax for the padding on the other hand has to be changed like this:
<item android:drawable="#color/button_focused" android:state_focused="true">
<shape
android:shape="rectangle">
<corners android:radius="20dip" />
<padding
android:left="8dip"
android:top="8dip"
android:right="8dip"
android:bottom="8dip" />
</shape>
</item>
Please note: as stated in the documentation for Shape Drawable,
Padding to apply to the containing View element (this pads the position of the View content, not the shape).
I want create in button with light button border with little 3D shade on edges like this
create an xml in your drawable
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list>
<item android:right="2dp" android:top="2dp">
<shape>
<corners android:radius="0dp" />
<solid android:color="#A09D9D"
/>
</shape>
</item>
<item android:bottom="1dp" android:left="1dp">
<shape>
<gradient android:angle="270"
android:endColor="#color/white"
android:startColor="#color/white" />
<stroke
android:width="0.5dp"
android:color="#CBCBC9" />
<corners
android:radius="0dp" />
</shape>
</item>
</layer-list>
</item>
</selector>
and use this xml as your button background
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<solid android:color="#color/white" />
<stroke android:width="1dip" android:color="#color/gray">
</stroke>
</shape>
Set this Xml on background
Is it possible to add a drop shadow to a custom shape in Android? After looking through the documentation, I only see a way to apply a text shadow.
I've tried this with no luck:
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#90ffffff"/>
<corners android:radius="12dp" />
<item name="android:shadowColor">#000000</item>
<item name="android:shadowRadius">5</item>
<item name="android:shadowDy">3</item>
</shape>
After Lots of search finally I got this
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Bottom 2dp Shadow -->
<item>
<shape android:shape="rectangle">
<solid android:color="#d8d8d8" />
<corners android:radius="7dp" />
</shape>
</item>
<!-- White Top color -->
<item android:bottom="3px">
<shape android:shape="rectangle">
<solid android:color="#FFFFFF" />
<corners android:radius="7dp" />
</shape>
</item>
</layer-list>
This is how I do it:
Code bellow for one button STATE:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- "background shadow" -->
<item>
<shape android:shape="rectangle" >
<solid android:color="#000000" />
<corners android:radius="15dp" />
</shape>
</item>
<!-- background color -->
<item

android:left="3px"
android:right="3px"
android:top="3px">

<corners android:radius="8dp" />
</shape>
</item>
<!-- over left shadow -->
<item>
<shape android:shape="rectangle" >
<gradient
android:angle="180"
android:centerColor="#00FF0000"
android:centerX="0.9"
android:endColor="#99000000"
android:startColor="#00FF0000" />
<corners android:radius="8dp" />
</shape>
</item>
<!-- over right shadow -->
<item>
<shape android:shape="rectangle" >
<gradient
android:angle="360"
android:centerColor="#00FF0000"
android:centerX="0.9"
android:endColor="#99000000"
android:startColor="#00FF0000" />
<corners android:radius="8dp" />
</shape>
</item>
<!-- over top shadow -->
<item>
<shape android:shape="rectangle" >
<gradient
android:angle="-90"
android:centerColor="#00FF0000"
android:centerY="0.9"
android:endColor="#00FF0000"
android:startColor="#99000000"
android:type="linear" />
<corners android:radius="8dp" />
</shape>
</item>
<!-- over bottom shadow -->
<item>
<shape android:shape="rectangle" >
<gradient
android:angle="90"
android:centerColor="#00FF0000"
android:centerY="0.9"

android:startColor="#99000000"
android:type="linear" />
<corners android:radius="8dp" />
</shape>
</item>
</layer-list>
Then you should have a selector with diferent versions of the button, something like:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/ic_button_red_pressed" android:state_pressed="true"/> <!-- pressed -->
<item android:drawable="#drawable/ic_button_red_selected" android:state_focused="true"/> <!-- focused -->
<item android:drawable="#drawable/ic_button_red_selected" android:state_selected="true"/> <!-- selected -->
<item android:drawable="#drawable/ic_button_red_default"/> <!-- default -->
</selector>
hope this can help you..good luck
This is my version of a drop shadow. I was going for a hazy shadow all around the shape and used this answer by Joakim Lundborg as my starting point. What I changed is to add corners to all the shadow items and to increase the radius of the corner for each subsequent shadow item. So here is the xml:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Drop Shadow Stack -->
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<solid android:color="#02000000" />
<corners android:radius="8dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<solid android:color="#05000000" />
<corners android:radius="7dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<solid android:color="#10000000" />
<corners android:radius="6dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<solid android:color="#15000000" />
<corners android:radius="5dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<solid android:color="#20000000" />
<corners android:radius="4dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<solid android:color="#25000000" />
<corners android:radius="3dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<solid android:color="#30000000" />
<corners android:radius="3dp" />
</shape>
</item>
<!-- Background -->
<item>
<shape>
<solid android:color="#0099CC" />
<corners android:radius="3dp" />
</shape>
</item>
</layer-list>
I think this method produces very good results:
<!-- Drop Shadow Stack -->
<item>
<shape>
<padding
android:top="1dp"
android:right="1dp"
android:bottom="1dp"
android:left="1dp"/>
<solid android:color="#00CCCCCC"/>
</shape>
</item>
<item>
<shape>
<padding
android:top="1dp"
android:right="1dp"
android:bottom="1dp"
android:left="1dp"/>
<solid android:color="#10CCCCCC"/>
</shape>
</item>
<item>
<shape>
<padding
android:top="1dp"
android:right="1dp"
android:bottom="1dp"
android:left="1dp"/>
<solid android:color="#20CCCCCC"/>
</shape>
</item>
<item>
<shape>
<padding
android:top="1dp"
android:right="1dp"
android:bottom="1dp"
android:left="1dp"/>
<solid android:color="#30CCCCCC"/>
</shape>
</item>
<item>
<shape>
<padding
android:top="1dp"
android:right="1dp"
android:bottom="1dp"
android:left="1dp"/>
<solid android:color="#50CCCCCC"/>
</shape>
</item>
<item>
<shape android:shape="rectangle">
<stroke android:color="#CCC" android:width="1dp"/>
<solid android:color="#FFF" />
<corners android:radius="2dp" />
</shape>
</item>
The following worked for me: Just save as custom_shape.xml.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- "shadow" -->
<item>
<shape android:shape="rectangle" >
<solid android:color="#000000"/>
<corners android:radius="12dp" />
</shape>
</item>
<item android:bottom="3px">
<shape android:shape="rectangle">
<solid android:color="#90ffffff"/>
<corners android:radius="12dp" />
</shape>
</item>
</layer-list>
I would suggest a small improvement to Bruce's solution which is to prevent overdrawing the same shape on top of each other and to simply use stroke instead of solid.
It would look like this:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Drop Shadow Stack -->
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<stroke android:color="#02000000" android:width="1dp" />
<corners android:radius="8dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<stroke android:color="#05000000" android:width="1dp" />
<corners android:radius="7dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<stroke android:color="#10000000" android:width="1dp" />
<corners android:radius="6dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<stroke android:color="#15000000" android:width="1dp" />
<corners android:radius="5dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<stroke android:color="#20000000" android:width="1dp" />
<corners android:radius="4dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<stroke android:color="#25000000" android:width="1dp" />
<corners android:radius="3dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<stroke android:color="#30000000" android:width="1dp" />
<corners android:radius="3dp" />
</shape>
</item>
<!-- Background -->
<item>
<shape>
<solid android:color="#FFF" />
<corners android:radius="3dp" />
</shape>
</item>
</layer-list>
Lastly I wanted to point out for people who would like a shadow in a specific direction that all you have to do is set the top, bottom, left or right to 0dp (for a solid line) or -1dp (for nothing)
Old question, but Elevation, available with Material Design now provides a shadow to any views.
<TextView
android:id="#+id/myview"
...
android:elevation="2dp"
android:background="#drawable/myrect" />
See the docs at https://developer.android.com/training/material/shadows-clipping.html
If you don't mind doing some custom drawing with the Canvas API, check out this answer about drop shadows. Here's a follow-up question to that one which fixes a problem in the original.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<solid android:color="#android:color/white" >
</solid>
<stroke
android:width="1dp"
android:color="#color/LightGrey" >
</stroke>
<padding
android:bottom="5dp"
android:left="2dp"
android:right="2dp"
android:top="5dp" >
</padding>
<corners
android:bottomLeftRadius="20dp"
android:bottomRightRadius="20dp"
android:radius="12dp"
android:topLeftRadius="20dp"
android:topRightRadius="20dp" />
<gradient
android:angle="90"
android:centerColor="#android:color/white"
android:centerY="0.2"
android:endColor="#99e0e0e0"
android:startColor="#android:color/white"
android:type="linear" />
</shape>
This question may be old, but for anybody in future that wants a simple way to achieve complex shadow effects check out my library here https://github.com/BluRe-CN/ComplexView
Using the library, you can change shadow colors, tweak edges and so much more. Here's an example to achieve what you seek for.
<com.blure.complexview.ComplexView
android:layout_width="400dp"
android:layout_height="600dp"
app:radius="10dp"
app:shadow="true"
app:shadowSpread="2">
<com.blure.complexview.ComplexView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:color="#fdfcfc"
app:radius="10dp" />
</com.blure.complexview.ComplexView>
To change the shadow color, use app:shadowColor="your color code".
9 patch to the rescue, nice shadow could be achieved easily
especially with this awesome tool -
Android 9-patch shadow generator
PS: if project won't be able to compile you will need to move black lines in android studio editor a little bit
I think this drop shadow value is good for most cases:
<solid android:color="#20000000" />
if you need a straight line shadow (like in bottom of toolbar) you can also use gradient xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:type="linear"
android:angle="-90"
android:startColor="#19000000" <!-- black transparent -->
android:endColor="#00000000" /> <!-- full transparent -->
</shape>
hope this help some one
For some reason shadows don't work if you set <solid> AND <stroke> on your custom background drawable. Creating a <layer-list> with separate layers for fill and borders fixes the issue:
<?xml version="1.0" encoding="utf-8"?>
<!-- Separate layers for solid and stroke, because no shadows get drawn otherwise (using elevation) -->
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#color/card_default" />
<corners android:radius="#dimen/card_corner_radius" />
</shape>
</item>
<item>
<shape android:shape="rectangle">
<stroke android:color="#color/card_border" android:width="#dimen/card_border_width"/>
<corners android:radius="#dimen/card_corner_radius" />
</shape>
</item>
</layer-list>
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:bottom="3dp"
android:left="5dp"
android:right="5dp"
android:top="5dp">
<shape android:shape="rectangle">
<gradient
android:startColor="#color/white"
android:endColor="#color/gray"
android:angle="270"
android:dither="false"/>
<corners android:radius="#dimen/_20dp" />
</shape>
</item>
<item
android:bottom="6dp"
android:left="6dp"
android:right="6dp"
android:top="6dp">
<shape android:shape="rectangle">
<solid android:color="#color/orange" />
<corners android:radius="#dimen/_20dp" />
</shape>
</item>
</layer-list>
Just set elevation to something like 10.

My question is really simple. That is about Button attrs.
I want to make Button which has only Top stoke. What can I set in layout xml ??
My xml file is
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false">
<shape>
<solid android:color="#android:color/transparent"/>
<stroke android:width="1dp" android:color="#color/btn_disable"
android:dashWidth="1dp" android:dashGap="0dp"/>
<padding android:left="9dp" android:top="2dp"
android:right="9dp" android:bottom="2dp"/>
<corners android:radius="#dimen/btn_radius" />
</shape>
</item>
<item android:state_pressed="true" >
<shape>
<solid android:color="#color/white_pressed"/>
<stroke android:width="1dp" android:color="#color/mint"
android:dashWidth="1dp" android:dashGap="0dp"/>
<padding android:left="9dp" android:top="2dp"
android:right="9dp" android:bottom="2dp"/>
<corners android:radius="#dimen/btn_radius" />
</shape>
</item>
<item>
<shape>
<solid android:color="#null"/>
<stroke android:width="1dp" android:color="#color/mint"
android:dashWidth="1dp" android:dashGap="0dp" />
<corners android:radius="#dimen/btn_radius" />
</shape>
</item>
</selector>
I cannot determine the exact shape you are looking for, but judging that you only want the top stroke, hide all other strokes, you can use a layer-list to achieve this.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle">
<solid android:color="your_stroke_colour" />
<corners
android:radius="your_radius" />
</shape>
</item>
<item
android:top="1dp"
android:bottom="0dp"
android:left="0dp"
android:right="0dp">
<shape android:shape="rectangle">
<solid android:color="your_color" />
<corners
android:radius="your_radius" />
</shape>
</item>
</layer-list>

Then you should have a selector with diferent versions of the button, something like:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/ic_button_red_pressed" android:state_pressed="true"/> <!-- pressed -->
<item android:drawable="#drawable/ic_button_red_selected" android:state_focused="true"/> <!-- focused -->
<item android:drawable="#drawable/ic_button_red_selected" android:state_selected="true"/> <!-- selected -->
<item android:drawable="#drawable/ic_button_red_default"/> <!-- default -->
</selector>
hope this can help you..good luck
This is my version of a drop shadow. I was going for a hazy shadow all around the shape and used this answer by Joakim Lundborg as my starting point. What I changed is to add corners to all the shadow items and to increase the radius of the corner for each subsequent shadow item. So here is the xml:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Drop Shadow Stack -->
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<solid android:color="#02000000" />
<corners android:radius="8dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<solid android:color="#05000000" />
<corners android:radius="7dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<solid android:color="#10000000" />
<corners android:radius="6dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<solid android:color="#15000000" />
<corners android:radius="5dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<solid android:color="#20000000" />
<corners android:radius="4dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<solid android:color="#25000000" />
<corners android:radius="3dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<solid android:color="#30000000" />
<corners android:radius="3dp" />
</shape>
</item>
<!-- Background -->
<item>
<shape>
<solid android:color="#0099CC" />
<corners android:radius="3dp" />
</shape>
</item>
</layer-list>
I think this method produces very good results:
<!-- Drop Shadow Stack -->
<item>
<shape>
<padding
android:top="1dp"
android:right="1dp"
android:bottom="1dp"
android:left="1dp"/>
<solid android:color="#00CCCCCC"/>
</shape>
</item>
<item>
<shape>
<padding
android:top="1dp"
android:right="1dp"
android:bottom="1dp"
android:left="1dp"/>
<solid android:color="#10CCCCCC"/>
</shape>
</item>
<item>
<shape>
<padding
android:top="1dp"
android:right="1dp"
android:bottom="1dp"
android:left="1dp"/>
<solid android:color="#20CCCCCC"/>
</shape>
</item>
<item>
<shape>
<padding
android:top="1dp"
android:right="1dp"
android:bottom="1dp"
android:left="1dp"/>
<solid android:color="#30CCCCCC"/>
</shape>
</item>
<item>
<shape>
<padding
android:top="1dp"
android:right="1dp"
android:bottom="1dp"
android:left="1dp"/>
<solid android:color="#50CCCCCC"/>
</shape>
</item>
<item>
<shape android:shape="rectangle">
<stroke android:color="#CCC" android:width="1dp"/>
<solid android:color="#FFF" />
<corners android:radius="2dp" />
</shape>
</item>
The following worked for me: Just save as custom_shape.xml.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- "shadow" -->
<item>
<shape android:shape="rectangle" >
<solid android:color="#000000"/>
<corners android:radius="12dp" />
</shape>
</item>
<item android:bottom="3px">
<shape android:shape="rectangle">
<solid android:color="#90ffffff"/>
<corners android:radius="12dp" />
</shape>
</item>
</layer-list>
I would suggest a small improvement to Bruce's solution which is to prevent overdrawing the same shape on top of each other and to simply use stroke instead of solid.
It would look like this:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Drop Shadow Stack -->
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<stroke android:color="#02000000" android:width="1dp" />
<corners android:radius="8dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<stroke android:color="#05000000" android:width="1dp" />
<corners android:radius="7dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<stroke android:color="#10000000" android:width="1dp" />
<corners android:radius="6dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<stroke android:color="#15000000" android:width="1dp" />
<corners android:radius="5dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<stroke android:color="#20000000" android:width="1dp" />
<corners android:radius="4dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<stroke android:color="#25000000" android:width="1dp" />
<corners android:radius="3dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="1dp" android:right="1dp" android:bottom="1dp" android:left="1dp" />
<stroke android:color="#30000000" android:width="1dp" />
<corners android:radius="3dp" />
</shape>
</item>
<!-- Background -->
<item>
<shape>
<solid android:color="#FFF" />

Lastly I wanted to point out for people who would like a shadow in a specific direction that all you have to do is set the top, bottom, left or right to 0dp (for a solid line) or -1dp (for nothing)
Old question, but Elevation, available with Material Design now provides a shadow to any views.
<TextView
android:id="#+id/myview"
...
android:elevation="2dp"
android:background="#drawable/myrect" />
See the docs at https://developer.android.com/training/material/shadows-clipping.html
If you don't mind doing some custom drawing with the Canvas API, check out this answer about drop shadows. Here's a follow-up question to that one which fixes a problem in the original.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<solid android:color="#android:color/white" >
</solid>
<stroke
android:width="1dp"
android:color="#color/LightGrey" >
</stroke>
<padding
android:bottom="5dp"
android:left="2dp"
android:right="2dp"
android:top="5dp" >
</padding>
<corners
android:bottomLeftRadius="20dp"
android:bottomRightRadius="20dp"
android:radius="12dp"
android:topLeftRadius="20dp"
android:topRightRadius="20dp" />
<gradient
android:angle="90"
android:centerColor="#android:color/white"
android:centerY="0.2"
android:endColor="#99e0e0e0"
android:startColor="#android:color/white"
android:type="linear" />
</shape>
This question may be old, but for anybody in future that wants a simple way to achieve complex shadow effects check out my library here https://github.com/BluRe-CN/ComplexView
Using the library, you can change shadow colors, tweak edges and so much more. Here's an example to achieve what you seek for.
<com.blure.complexview.ComplexView
android:layout_width="400dp"
android:layout_height="600dp"
app:radius="10dp"
app:shadow="true"
app:shadowSpread="2">
<com.blure.complexview.ComplexView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:color="#fdfcfc"
app:radius="10dp" />
</com.blure.complexview.ComplexView>
To change the shadow color, use app:shadowColor="your color code".
9 patch to the rescue, nice shadow could be achieved easily
especially with this awesome tool -
Android 9-patch shadow generator
PS: if project won't be able to compile you will need to move black lines in android studio editor a little bit
I think this drop shadow value is good for most cases:
<solid android:color="#20000000" />
if you need a straight line shadow (like in bottom of toolbar) you can also use gradient xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:type="linear"
android:angle="-90"
android:startColor="#19000000" <!-- black transparent -->
android:endColor="#00000000" /> <!-- full transparent -->
</shape>
hope this help some one
For some reason shadows don't work if you set <solid> AND <stroke> on your custom background drawable. Creating a <layer-list> with separate layers for fill and borders fixes the issue:
<?xml version="1.0" encoding="utf-8"?>
<!-- Separate layers for solid and stroke, because no shadows get drawn otherwise (using elevation) -->
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#color/card_default" />
<corners android:radius="#dimen/card_corner_radius" />
</shape>
</item>
<item>
<shape android:shape="rectangle">
<stroke android:color="#color/card_border" android:width="#dimen/card_border_width"/>
<corners android:radius="#dimen/card_corner_radius" />
</shape>
</item>
</layer-list>
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:bottom="3dp"
android:left="5dp"
android:right="5dp"
android:top="5dp">
<shape android:shape="rectangle">
<gradient
android:startColor="#color/white"
android:endColor="#color/gray"
android:angle="270"
android:dither="false"/>
<corners android:radius="#dimen/_20dp" />
</shape>
</item>
<item
android:bottom="6dp"
android:left="6dp"
android:right="6dp"
android:top="6dp">
<shape android:shape="rectangle">
<solid android:color="#color/orange" />
<corners android:radius="#dimen/_20dp" />
</shape>
</item>
</layer-list>
Just set elevation to something like 10.
