According to my app ui requirement it's need plain side on top of cardview so, it need to remove shadow from upper side and touch to another view.
I tried
card_view:cardElevation="0dp"
but it removed shadow from all side, so it's not useful to me.
I tried by negative margin (-5dp) applied to CardView and image view one by one but all time CardView is come over the image not under the image so,it doesn't worked for me.
App ui requirement is like this
Can any one give suggestions of do help to solve this?
I come out from this problem by creating the custom background look like card view but without top shadow.
Create one XML file in drawable folder and put this code inside and set it in background.
android:background="#drawable/custom_cardview_no_top_shadow"
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<padding android:top="0dp" android:right="10dp" android:bottom="5dp" android:left="10dp" />
<solid android:color="#color/transparent" />
</shape>
</item>
<item>
<shape>
<padding android:top="0dp" android:right="0dp" android:bottom="1dp" android:left="0dp" />
<solid android:color="#color/card_shadow_1" />
<corners android:radius="0dp" />
</shape>
</item>
<item>
<shape>
<padding android:top="0dp" android:right="0dp" android:bottom="1dp" android:left="0dp" />
<solid android:color="#color/card_shadow_2" />
<corners android:radius="0dp" />
</shape>
</item>
<!-- Background -->
<item>
<shape >
<solid android:color="#color/card_background" />
<corners android:radius="0dp" />
</shape>
</item>
</layer-list>
Here is the color for the Card view
<!-- card colors -->
<color name="card_background">#ffffff</color>
<color name="card_shadow_1">#d4d4d4</color>
<color name="card_shadow_2">#dddddd</color>
<color name="transparent">#00000000</color>
You can achieve this kind of effect by creating another view that is higher than cardview in z axis. After that you need to set its outlineProvider property to none to disable shadow effect and place it to the desired edge of CardView.
<RelativeLayout>
<CardView/>
<View
..
android:outlineProvider="none"
android:translationZ="12dp"
android:background="#color/cardViewBackgroundColor>
</View>
</RelativeLayout>

How to add border around linear layout except at the bottom ?
LinearLayout needs to have border at left, top and right side but not at the bottom.
Create an XML file named border.xml in the drawable folder and put the following code in it.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#FF0000" />
</shape>
</item>
<item android:left="5dp" android:right="5dp" android:top="5dp" >
<shape android:shape="rectangle">
<solid android:color="#000000" />
</shape>
</item>
</layer-list>
Then add a background to your linear layout like this:
android:background="#drawable/border"
EDIT :
This XML was tested with a galaxy s running GingerBread 2.3.3 and ran perfectly as shown in image below:
ALSO
tested with galaxy s 3 running JellyBean 4.1.2 and ran perfectly as shown in image below :
Finally its works perfectly with all APIs
EDIT 2 :
It can also be done using a stroke to keep the background as transparent while still keeping a border except at the bottom with the following code.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:left="0dp" android:right="0dp" android:top="0dp"
android:bottom="-10dp">
<shape android:shape="rectangle">
<stroke android:width="10dp" android:color="#B22222" />
</shape>
</item>
</layer-list>
hope this help .
Save this xml and add as a background for the linear layout....
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="4dp" android:color="#FF00FF00" />
<solid android:color="#ffffff" />
<padding android:left="7dp" android:top="7dp"
android:right="7dp" android:bottom="0dp" />
<corners android:radius="4dp" />
</shape>
Hope this helps! :)
Kenny is right, just want to clear some things out.
Create the file border.xml and put it in the folder res/drawable/
add the code
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="4dp" android:color="#FF00FF00" />
<solid android:color="#ffffff" />
<padding android:left="7dp" android:top="7dp"
android:right="7dp" android:bottom="0dp" />
<corners android:radius="4dp" />
</shape>
set back ground like android:background="#drawable/border" wherever you want the border
Mine first didn't work cause i put the border.xml in the wrong folder!
Here is a Github link to a lightweight and very easy to integrate library that enables you to play with borders as you want for any widget you want, simply based on a FrameLayout widget.
Here is a quick sample code for you to see how easy it is, but you will find more information on the link.
<com.khandelwal.library.view.BorderFrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:leftBorderColor="#00F0F0"
app:leftBorderWidth="10dp"
app:topBorderColor="#F0F000"
app:topBorderWidth="15dp"
app:rightBorderColor="#F000F0"
app:rightBorderWidth="20dp"
app:bottomBorderColor="#000000"
app:bottomBorderWidth="25dp" >
</com.khandelwal.library.view.BorderFrameLayout>
So, if you don't want borders on bottom, delete the two lines about bottom in this custom widget, and that's done.
And no, I'm neither the author of this library nor one of his friend ;-)
I want to make a drawable for my Android button, defined as drawable. I found I could set all the borders by using a rectangle, but I got kinda stuck when I wanted it on three sides. I want for example have either the top or the bottom open.
Could anyone show me how to do this?
Try doing this, though I saw it on some other post
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle" >
<solid android:color="#FFFFFF" />
<padding
//android:bottom="10dp" Remove this to avoid seeing the bottom border
android:left="10dp"
android:right="10dp"
//android:top="10dp" Remove this to avoid seeing the top border
/>
<corners android:radius="5dp" />
</shape>
</item>
<item>
<shape android:shape="rectangle" >
<padding
android:bottom="5dp"
android:left="5dp"
android:right="5dp"
android:top="5dp" />
<solid android:color="#666666" />
</shape>
</item>
</layer-list>
https://stackoverflow.com/a/10133434/1244489
If anyone is running into issues regarding padding taking effect in the accepted answer, try taking a look at: https://stackoverflow.com/a/11006931. That solution uses position attributes on the tags to achieve the same effect.
I was having trouble using the accepted answer here while creating drawables for use in an ActionBar, and the linked approach worked for me.
This might help you.
I The border on Three sides of the XML
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

I want my Spinner to have a black gradient background with white text on the left and a selector icon on the right (a white downwards pointing triangle). As I see it there are two ways of going about this:
If I set the background to an xml drawable resource I can make my Spinner look perfect, but then I need to somehow add the white triangle on the right, which I don't know how to go about:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<gradient
android:startColor="#343434"
android:endColor="#171717"
android:angle="270" />
<stroke
android:width="1dp"
android:color="#ffffff" />
<corners
android:radius="4dp" />
<padding
android:left="3dp"
android:top="3dp"
android:right="3dp"
android:bottom="3dp" />
</shape>
</item>
</selector>
I create a 9-patch image which includes the triangle and then use xml to round the corners and add a stroke to the image. I have had a go at this but was unable to make it work:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/spinnerblack" >
<stroke
android:width="1dp"
android:color="#ffffff" />
<corners
android:radius="3dp" />
<padding
android:left="3dp"
android:top="3dp"
android:right="3dp"
android:bottom="3dp" />
</item>
</selector>
Could someone either tell me what I can do for method 1 or what I have done wrong in method 2? I would prefer not to have to add the stroke and rounded corners in my 9-patch image because I don't think it ever looks as good. Also, I would prefer method 1 to method 2. Any help much appreciated.
I've done something similar to method 1 in my app. Basically you need to combine your selector with a layer-list:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list>
<item>
<shape>
<gradient
android:startColor="#343434"
android:endColor="#171717"
android:angle="270" />
<stroke
android:width="1dp"
android:color="#ffffff" />
<corners
android:radius="4dp" />
<padding
android:left="3dp"
android:top="3dp"
android:right="3dp"
android:bottom="3dp" />
</shape>
</item>
<item
android:top="12dp"
android:right="15dp">
<bitmap android:src="#drawable/arrow_bitmap"
android:gravity="top|right" />
</item>
</layer-list>
</item>
</selector>
In my xml I also added a third layer containing a <shape> that is invisible (i.e. its alpha is set to 0) but adds padding.
Using Android Shapes in xml I have defined a gradient which I use as the background for a button.
This all works nice, but there's no edge surrounding the button. I would like it to look similar to the normal Android button but I need more flexibility to control the color and look.
The shape is defined as follows:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient android:startColor="#FFFFFF"
android:endColor="#00FF00"
android:angle="270" />
<corners android:radius="3dp" />
<stroke android:width="5px" color="#000000" />
</shape>
I would expect the border to be set in the xml. Why doesn't "stroke" fix it? Stroke doesn't seem to do anything.
I checked the Android Developer spec, but couldn't find the answer there:
http://developer.android.com/guide/topics/resources/drawable-resource.html
I have also looked through all the properties of the Android Button, but as expected there's no such parameter, probably since it's built into the normal Android button. Btw, I checked ImageButton properties too.
Can someone please help?
I know there's the alternative to make an image with proper edges and use an ImageButton, but there really should be a way to fix this programmatically.
Thanks!

I had this problem a while ago. While I don't quite remember why I made each decision, the way I solved it was to use a a shape layer-list. This lets you stack one shape on top of another. For example, the following XML creates a shape with a solid black outline 2px wide, with a 'grey to white to grey' gradient across the middle:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<padding android:left="1dp"
android:top="1dp"
android:right="1dp"
android:bottom="1dp"/>
<solid android:color="#FF000000"/>
<corners android:radius="3dp"/>
</shape>
</item>
<item>
<shape>
<padding android:left="2dp"
android:top="2dp"
android:right="2dp"
android:bottom="2dp"/>
<gradient android:startColor="#FFB0B0B0"
android:centerColor="#FFFFFFFF"
android:endColor="#FFB0B0B0"
android:angle="315"/>
</shape>
</item>
</layer-list>
If you want to be able to change that color dynamically at runtime, then things get a lot messier. Again, the details of why I had to do things a certain way are hazy, but I ended up having to create a custom view class which contained a custom ShapeDrawable. I started off looking at the examples from the ApiDemos app which comes with the SDK - it's a very good resource.
EDIT: Another reason your stroke might not be appearing is that you forgot the android: before the color="...." bit.
I've had the same problem, what i observed is stroke is not applying to button as border at design time but at run time i see the border.
I jst used the following same code
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:padding="10dp">
<solid android:color="#color/black" />
<stroke android:width="1px" android:color="#color/red" />
</shape>
as steve hanley said abvoe you miss the android: for the color attribute.
Hope this helps somebody....
Probably much to late, but you have to add an extra ff before the color.
<stroke android:width="5px" color="#ff000000" />

Use ImageButton
<ImageButton
android:layout_width="40dp"
android:layout_height="30dp"
android:src="#drawable/left_arrow"
android:background="#drawable/button_selector"
android:gravity="center"/>
Use drawable selector to ImageButton and define your properties
<item android:state_pressed="true" >
<shape>
<gradient
android:startColor="#color/startColor"
android:endColor="#color/endColor"
android:angle="270" />
<stroke
android:width="0.5dp"
android:color="#color/borderColor" />
<corners
android:topLeftRadius="5dp"
android:bottomRightRadius="5dp"/>
</shape>
</item>
<item android:state_focused="true" >
<shape>
<gradient
android:startColor="#color/startColor"
android:endColor="#color/endColor"
android:angle="270" />
<stroke
android:width="0.5dp"
android:color="#color/borderColor" />
<corners
android:topLeftRadius="5dp"
android:bottomRightRadius="5dp"/>
</shape>
</item>
<item>
<shape>
<gradient
android:startColor="#color/startColor"
android:endColor="#color/endColor"
android:angle="270" />
<stroke
android:width="0.5dp"
android:color="#color/borderColor" />
<corners
android:topLeftRadius="5dp"
android:bottomRightRadius="5dp"/>
</shape>
</item>
<item android:state_enabled="false" android:drawable="#drawable/button_disabled" />
<item android:state_focused="true" android:drawable="#drawable/button_highlighted"/>
<item android:state_pressed="true" android:drawable="#drawable/button_highlighted"/>
<item>
<shape>
<gradient android:startColor="#fdfdfd" android:endColor="#f0f0f0" android:angle="270" />
<stroke android:width="1dp" android:color="#56390a" />
<corners android:radius="3dp" />
<padding android:left="10dp" android:top="10dp" android:right="10dp" android:bottom="10dp" />
</shape>
</item>
Adding stroke color #56390a will solve the problem.
I'm creating a custom progress bar (positioned under a WebView) and what I would like to draw is a 1dp-wide line between the WebView and the ProgressBar. I'm modifying existing drawable, namely progress_horizontal.xml, and tried something like this:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
(...)
<item>
<shape android:shape="line">
<stroke android:width="1dp" android:color="#FF000000" />
</shape>
</item>
</layer-list>
This line however is vertically centered but I want it to be drawn on top of the drawable. The only idea I could come up with is to use this "hacky" gradient below:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
(...)
<item>
<shape>
<gradient
android:startColor="#FF000000"
android:centerColor="#00000000"
android:centerY="0.01"
android:endColor="#00000000"
android:angle="270"
/>
</shape>
</item>
</layer-list>
Do you have better ideas how to draw a single line shape aligned to the top of the drawable defined with layer-list?
I spent a while trying to figure this out as well. Hopefully there is a better way to do it but here is the method I used, which is also kind of hackish, but in case it helps someone, I thought I would share.
The first item in your layer list should be a solid of whatever color you want to be your border. Following that would be the thing(s) you want to have the border, with padding on whatever side you want the border to be on.
For example:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="YOUR BORDER COLOR" />
</shape>
</item>
<item android:top="YOUR TOP BORDER THICKNESS">
THE THING YOU WANT A BORDER ON
</item>
</layer-list>
The idea is that the padding on the item reveals the solid shape behind it, giving the border appearance. You could add padding to any side to add a border. I imagine you could get more complicated and have different colored borders this way as well.
Seems like a hack but it worked for me.
EDIT: I said "padding" but in layer-lists it's more of an offset.
i was going through all related topics but no one could solve my problem. But some of them were very useful to understand how the layer-list or shape parameters work.
My problem was to define a button with a linear gradient and draw a top and a bottom line in different colors. After all I hacked this solution. I saved the file unter res/drawable/blue_btn.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" >
<shape android:shape="rectangle">
<solid android:color="#color/blue_end" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
<stroke
android:width="1dp"
android:color="#color/bottomline_btn" />
</shape>
</item>
<item>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle">
<solid android:color="#color/blue" />
<gradient
android:startColor="#color/blue"
android:endColor="#color/blue_end"
android:angle="270" />
</shape>
</item>
<item android:top="0dp" android:bottom="-1dp" android:left="-1dp" android:right="-1dp">
<shape android:shape="rectangle">
<stroke
android:width="1dp"
android:color="#color/topline_btn" />
<solid android:color="#00000000" />
<corners android:radius="0dp" />
</shape>
</item>
<item android:top="-1dp" android:bottom="0dp" android:left="-1dp" android:right="-1dp">
<shape android:shape="rectangle">
<stroke
android:width="1dp"
android:color="#color/bottomline_btn" />
<solid android:color="#00000000" />
<corners android:radius="0dp" />
</shape>
</item>
</layer-list>
</item>
</selector>
<color name="topline_btn">#31ffffff</color>
<color name="bottomline_btn">#31000000</color>
<color name="blue">#449def</color>
<color name="blue_end">#2f6699</color>
Did you try offsetting it by something like this
http://android.amberfog.com/?p=9
My solution is to add 9-patch as the last layer item :
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape>
<solid android:color="#color/tab_button_active_layer2" />
</shape>
</item>
<item android:bottom="#dimen/tab_button_active_bottom_bar_width">
<shape>
<solid android:color="#color/tab_button_active_layer1" />
</shape>
</item>
<!-- 9-patch drawable -->
<item android:drawable="#drawable/tab_button_border_top"/>
</layer-list>
