Android shape border with gradient and middle transparent

I need to create a round corner border, where border with gradient.enter link description here is working.But My page is using a image as background which is also with gradient. I need to show background image from middle of the filed. I want to create just like below image:

round_background.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="4dp"
android:color="#color/transparent" />
<gradient
android:startColor="#374533"
android:centerColor="#432727"
android:endColor="#222430"
android:angle="135"/>
<corners android:radius="10dp" />
</shape>
round_border.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:startColor="#efe301"
android:centerColor="#7dc17b"
android:endColor="#01dae6"
android:angle="180"/>
<corners android:radius="10dp" />
result_drawable.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/round_border"/>
<item android:drawable="#drawable/round_background" />
</layer-list>
Here, you can set android:width="4dp" in round_background.xml to set size of your border. use result result_drawable.xml where you want..

Android LinearLayout : Add border with shadow around a LinearLayout

I would like to create the same border of this LinearLayout as the example :
In this example, we can see that the border is not the same all around the linearLayout.
How can I create this using an XML drawable file?
For now, I have only able to create a simple border all around the LinearLayout like this :
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<corners
android:radius="1dp"
android:topRightRadius="0dp"
android:bottomRightRadius="0dp"
android:bottomLeftRadius="0dp" />
<stroke
android:width="1dp"
android:color="#E3E3E1" />
<solid android:color="#color/blanc" />
</shape>

Try this..
<?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="#CABBBBBB"/>
<corners android:radius="2dp" />
</shape>
</item>
<item
android:left="0dp"
android:right="0dp"
android:top="0dp"
android:bottom="2dp">
<shape android:shape="rectangle">
<solid android:color="#android:color/white"/>
<corners android:radius="2dp" />
</shape>
</item>
</layer-list>

That's why CardView exists. CardView | Android Developers
It's just a FrameLayout that supports elevation in pre-lollipop devices.
<android.support.v7.widget.CardView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:cardUseCompatPadding="true"
app:cardElevation="4dp"
app:cardCornerRadius="3dp" >
<!-- put whatever you want -->
</android.support.v7.widget.CardView>
To use this you need to add dependency to build.gradle:
compile 'com.android.support:cardview-v7:23.+'

I get the best looking results by using a 9 patch graphic.
You can simply create an individual 9 patch graphic by using the following editor:
http://inloop.github.io/shadow4android/
Example:
The 9 patch graphic:
The result:
The source:
<LinearLayout
android:layout_width="200dp"
android:layout_height="200dp"
android:orientation="vertical"
android:background="#drawable/my_nine_patch"

okay, i know this is way too late. but i had the same requirement. i solved like this
1.First create a xml file (example: border_shadow.xml) in "drawable"
folder and copy the below code into it.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<item>
<shape>
<!-- set the shadow color here -->
<stroke
android:width="2dp"
android:color="#7000" />
<!-- setting the thickness of shadow (positive value will give shadow on that side) -->
<padding
android:bottom="2dp"
android:left="2dp"
android:right="-1dp"
android:top="-1dp" />
<corners android:radius="3dp" />
</shape>
</item>
<!-- Background -->
<item>
<shape>
<solid android:color="#fff" />
<corners android:radius="3dp" />
</shape>
</item>
</layer-list>
2.now on the layout where you want the shadow(example: LinearLayout) add this in android:background
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="8dip"
android:background="#drawable/border_shadow"
android:orientation="vertical">
and that worked for me.

This is so simple:
Create a drawable file with a gradient like this:
for shadow below a view below_shadow.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:startColor="#20000000"
android:endColor="#android:color/transparent"
android:angle="270" >
</gradient>
</shape>
for shadow above a view above_shadow.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:startColor="#20000000"
android:endColor="#android:color/transparent"
android:angle="90" >
</gradient>
</shape>
and so on for right and left shadow just change the angle of the gradient :)

As an alternative, you might use a 9 patch image as the background for your layout, allowing for more "natural" shadows:
Result:
Put the image in your /res/drawable folder.
Make sure the file extension is .9.png, not .png
By the way, this is a modified (reduced to the minimum square size) of an existing resource found in the API 19 sdk resources folder.
I left the red markers, since they don't seem to be harmful, as shown in the draw9patch tool.
[EDIT]
About 9 patches, in case you never had anything to do with them.
Simply add it as the background of your View.
The black-marked areas (left and top) will stretch (vertically, horizontally).
The black-marked areas (right, bottom) define the "content area" (where it's possible to add text or Views - you can call the unmarked regions "padding", if you like to).
Tutorial: http://radleymarx.com/blog/simple-guide-to-9-patch/

You create a file .xml in drawable with name drop_shadow.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!--<item android:state_pressed="true">
<layer-list>
<item android:left="4dp" android:top="4dp">
<shape>
<solid android:color="#35000000" />
<corners android:radius="2dp"/>
</shape>
</item>
...
</layer-list>
</item>-->
<item>
<layer-list>
<!-- SHADOW LAYER -->
<!--<item android:top="4dp" android:left="4dp">
<shape>
<solid android:color="#35000000" />
<corners android:radius="2dp" />
</shape>
</item>-->
<!-- SHADOW LAYER -->
<item>
<shape>
<solid android:color="#35000000" />
<corners android:radius="2dp" />
</shape>
</item>
<!-- CONTENT LAYER -->
<item android:bottom="3dp" android:left="1dp" android:right="3dp" android:top="1dp">
<shape>
<solid android:color="#ffffff" />
<corners android:radius="1dp" />
</shape>
</item>
</layer-list>
</item>
</selector>
Then:
<LinearLayout
...
android:background="#drawable/drop_shadow"/>

1.First create a xml file name shadow.xml in "drawable" folder and copy the below code into 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="#CABBBBBB" />
<corners android:radius="10dp" />
</shape>
</item>
<item
android:bottom="6dp"
android:left="0dp"
android:right="6dp"
android:top="0dp">
<shape android:shape="rectangle">
<solid android:color="#android:color/white" />
<corners android:radius="4dp" />
</shape>
</item>
</layer-list>
Then add the the layer-list as background in your LinearLayout.
<LinearLayout
android:id="#+id/header_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/shadow"
android:orientation="vertical">

Use this single line and hopefully you will achieve the best result;
use:
android:elevation="3dp" Adjust the size as much as you need and this is the best and simplest way to achieve the shadow like buttons and other default android shadows.
Let me know if it worked!

If you already have the border from shape just add elevation:
<LinearLayout
android:id="#+id/layout"
...
android:elevation="2dp"
android:background="#drawable/rectangle" />

I know this is late but it could help somebody.
You can use a constraintLayout and add the following property in the xml,
android:elevation="4dp"

I found the best way to tackle this.
You need to set a solid rectangle background on the layout.
Use this code - ViewCompat.setElevation(view , value)
On the parent layout set android:clipToPadding="false"

Add only top and bottom border on LinearLayout [duplicate]

This question already has answers here:
Is there an easy way to add a border to the top and bottom of an Android View?
(25 answers)
Closed 1 year ago.
I would like to add only a bottom and a top border on my Linearlayout.
I have tried to do this :
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:bottom="1dp"
android:top="1dp">
<shape android:shape="rectangle">
<solid android:color="#FFFFFF" />
<stroke
android:width="1dp"
android:color="#000" />
</shape>
</item>
</layer-list>
But it add a border around the shape..
Could you help me please ?

I think you can create this drawable and use it as background:
<?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="#000"/>
</shape>
</item>
<item android:bottom="1dp" android:top="1dp">
<shape android:shape="rectangle" >
<solid android:color="#FFFFFF" />
</shape>
</item>
</layer-list>
Think of is as drawing a rectangle with border color first and then lay on top of it a rectangle with your background color leaving out 1dp on top and at the bottom.

Make this two file and put this code. you can set border top and bottom border,
main.xml
<TextView
android:text="This is textline"
android:background="#drawable/border_set"
/>
border_set.xml
This file located into full path project_root/res/drawable/border_set.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape
android:shape="rectangle">
<stroke android:width="1dp" android:color="#FF000000" />
<solid android:color="#FFDDDDDD" />
</shape>
</item>
<item android:top="1dp" android:bottom="1dp">
<shape
android:shape="rectangle">
<stroke android:width="1dp" android:color="#000" />
<solid android:color="#FFFFFF" />
</shape>
</item>
</layer-list>

Here is the solution. It works even with transparent background.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:left="-2dp" android:right="-2dp">
<shape android:shape="rectangle">
<stroke android:width="2dp" android:color="#color/borderColor" />
<solid android:color="#color/backgroundColor" />
</shape>
</item>
</layer-list>

I believe this is the simplest way:
<View
android:layout_width="match_parent"
android:layout_height="2dp"
android:background="#000000" />

This is my version; top border and bottom border are visible, not showing the left or right borders. And the background is transparent.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="1dp">
<item
android:left="-1dp"
android:right="-1dp"
android:top="-1dp"
android:bottom="1dp">
<shape
android:shape="rectangle">
<stroke
android:width="1dp"
android:color="#color/BlueGrey_colorPrimary" />
<solid android:color="#android:color/transparent" />
</shape>
</item>
</layer-list>

A quick way to achieve this:
Add a Text View to the bottom and/or top of your layout.
Set the TextView's width to "match_parent"
Set the TextView's height to about "1dp" or find the thickness you would like
Set the TextView's background to the color you would like the border to be
I hope this helps!

You can follow this link Is there an easy way to add a border to the top and bottom of an Android View?
I expect that you are solve from this link.
also you can solve How to add border around linear layout except at the bottom?

Its simple. Draw 3 shapes like this.
<?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="#color/menu_line_separator_in" />
</shape>
</item>
<item android:bottom="1.5dp">
<shape android:shape="rectangle" >
<solid android:color="#color/menu_line_separator_out" />
</shape>
</item>
<item android:top="1.5dp">
<shape android:shape="rectangle" >
<solid android:color="#color/menu_line_separator_out" />
</shape>
</item>
</layer-list>

Square shaped layout border with round inside edges

I’m attempting to create a layout border with corners that are square on the outside and round on the inside. I’ve gathered that I need to create an .xml drawable definition composed of two shapes: one with a stroke width and corner radius and another with a stroke width only:
The drawables
round_border.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="4dp" android:color="#FF000000" />
<padding android:left="7dp" android:top="7dp"
android:right="7dp" android:bottom="7dp" />
<corners android:radius="4dp" />
<solid android:color="#FFC0C0C0" />
</shape>
square_border.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="2dp" android:color="#FF000000" />
<solid android:color="#FFC0C0C0" />
</shape>
Each of these works independantly as a border when appliedby itself like so:
android:background="#drawable/round_border"
but when they either or both are added to an item-list drawable like so:
composite_border.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<layer-list>
<item android:drawable="#drawable/round_border"/>
<!-- <item android:drawable="#drawable/square_border"/> -->
</layer-list>
</shape>
and:
android:background="#drawable/composite_border"
The layout's background is completely black instead of just a black border.
Does anyone know how to make the layer list work for this task?

From Shape Drawable Doc you can see that shape can't have layer-list inside so you should define your composite_border.xml like this
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/square_border"/>
<item android:drawable="#drawable/round_border"/>
</layer-list>
note that I changed the order of your items inside the layer-list as stated in the documentation of layer-list
Each drawable in the list is drawn in the order of the list—the last drawable in the list is drawn on top and you want it to be squared from outside

Try this will work fine enough:
solid is background color
stroke is border
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid
android:color="#color/white"/>
<stroke android:width="1dp" android:color="#ffaaaaaa" />
<size
android:width="15dp"
android:height="15dp"/>
</shape>

Create a xml file like round_background.xml:
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid
android:color="#CCCC33"/>
<size
android:width="35dp"
android:height="35dp"/>
</shape>
In the layout set as background
<LinearLayout
android:id="#+id/layout_wellbeing"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center"
android:background="#drawable/rounded_corner_leuvan"
android:orientation="horizontal" >
</LinearLayout>

square_border.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="2dp"
android:color="#FF000000"
/>
<solid android:color="#FFC0C0C0" />
</shape>
composite_border.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<layer-list>
<item android:drawable="#drawable/round_border"/>
<!-- <item android:drawable="#drawable/square_border"/> -->
</layer-list>
</shape>
watch out the comments and the quotation marks! =]

Drawing top border on a shape on Android

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>
