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"

EDIT: suggested solutions here offer me to draw the shadows myself. I
don't want that as the view will be animated (translationZ will change
over time) and I would like to avoid rendering the shadows myself
during the animation. I would like some solution to help
android-system recognize my shape as a background for the elevation.
If no such solution will be found, the hard way will be subclassing a
ViewOutlineProvider with convexPath, but I would really like to avoid
this.
As the name of the question suggests, I have a problem getting android's elevation to work with a rectangle of different rounded-corners. (pictures added at the end of the question)
It does work when there is only 1 default radius, i.e with this example:
rounded_rect.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid android:color="#android:color/holo_orange_dark"/>
<corners android:radius="5dp"/>
</shape>
activity.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<View
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_marginBottom="8dp"
android:layout_marginEnd="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:background="#drawable/rounded_rect"
android:elevation="5dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
But when I'm changing rounded_rect.xml to the following code, no shadows are being casted:
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid android:color="#android:color/holo_orange_dark"/>
<corners
android:bottomRightRadius="5dp"
android:bottomLeftRadius="20dp"
android:topLeftRadius="10dp"
android:topRightRadius="30dp"
/>
</shape>
I have tried adding also android:radius="5dp" into the <corners> tag in rounded_rect.xml , but it didn't add shadows.
Any help would be much appreciated!
picture working with default radius for all corners:
picture not working with different radius for each corner - no shadows:
Refer 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>
I got it to work using my custom subclass of ViewOutlineProvider . in my subclass I calculated a Path that its isConvex() returns true, and used that path as the shadow.
use this online making tool this will help you to make shapes
in that at border radius
Apply this code. Set the button as per your requirement

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>
I need to create an android shape so that only the bottom has stroke (a dashed line). When I try the following, the stroke bisects the shape right through the center. Does anyone know how to get it right? the stroke needs to be the bottom line/border. I am using the shape as a background to a TextView. Please, never mind why I need 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="#1bd4f6" />
</shape>
</item>
<item>
<shape android:shape="line" >
<padding android:bottom="1dp" />
<stroke
android:dashGap="10px"
android:dashWidth="10px"
android:width="1dp"
android:color="#ababb2" />
</shape>
</item>
</layer-list>
It's kind of a hack, but I think this is probably the best way to do it. The dashed line will always be on the bottom, regardless of the height.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle" >
<solid android:color="#1bd4f6" />
</shape>
</item>
<item android:top="-2dp" android:right="-2dp" android:left="-2dp">
<shape>
<solid android:color="#android:color/transparent" />
<stroke
android:dashGap="10px"
android:dashWidth="10px"
android:width="1dp"
android:color="#ababb2" />
</shape>
</item>
</layer-list>
Explanation:
The second shape is transparent rectangle with a dashed outline. The key in making the border only appear along the bottom lies in the negative margins set the other sides. These negative margins "push" the dashed line outside the drawn area on those sides, leaving only the line along the bottom. One potential side-effect (which I haven't tried) is that, for views that draw outside their own bounds, the negative-margin borders may become visible.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:top="-6dp"
android:left="-6dp"
android:right="-6dp"
android:bottom="0dp">
<shape android:shape="rectangle">
<solid android:color="#88FFFF00"/>
<stroke
android:width="5dp"
android:color="#FF000000"/>
</shape>
</item>
</layer-list>
This does the trick...
<item >
<shape android:shape="rectangle">
<solid android:color="#YOUR_BOTTOM_LINE_COLOR"/>
</shape>
</item>
<item android:bottom="1.5dp">
<shape android:shape="rectangle">
<solid android:color="#YOUR_BG_COLOR"/>
</shape>
</item>
I feel it is straightforward, without all this negative paddings or storks.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/main_bg_color"/>
<item android:gravity="bottom">
<shape android:shape="rectangle">
<size android:height="5dp"/>
<solid android:color="#color/bottom_bar_color"/>
</shape>
</item>
</layer-list>
This answer is for those google searchers who want to show dotted bottom border of EditText like here
Create dotted.xml inside drawable folder and paste these
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:bottom="1dp"
android:left="-2dp"
android:right="-2dp"
android:top="-2dp">
<shape android:shape="rectangle">
<stroke
android:width="0.5dp"
android:color="#android:color/black" />
<solid android:color="#ffffff" />
<stroke
android:width="1dp"
android:color="#030310"
android:dashGap="5dp"
android:dashWidth="5dp" />
<padding
android:bottom="5dp"
android:left="5dp"
android:right="5dp"
android:top="5dp" />
</shape>
</item>
</layer-list>
Then simply set the android:background attribute to dotted.xml we just created. Your EditText looks like this.
<EditText
android:id="#+id/editText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Some Text"
android:background="#drawable/dotted" />
Try next xml drawable code:
<layer-list>
<item android:top="-2dp" android:right="-2dp" android:left="-2dp">
<shape>
<solid android:color="#android:color/transparent" />
<stroke
android:width="1dp"
android:color="#fff" />
</shape>
</item>
</layer-list>
I think you do not need to use shape if I understood you.
If you are looking as shown in following image then use following layout.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:background="#1bd4f6"
android:paddingBottom="4dp" >
<TextView
android:layout_width="200dp"
android:layout_height="wrap_content"
android:background="#ababb2"
android:padding="5dp"
android:text="Hello Android" />
</RelativeLayout>
</RelativeLayout>
EDIT
play with these properties you will get result
android:top="dimension"
android:right="dimension"
android:bottom="dimension"
android:left="dimension"
try 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="#1bd4f6" />
</shape>
</item>
<item android:top="20px"
android:left="0px">
<shape android:shape="line" >
<padding android:bottom="1dp" />
<stroke
android:dashGap="10px"
android:dashWidth="10px"
android:width="1dp"
android:color="#ababb2" />
</shape>
</item>
</layer-list>
A Simple solution :
Create a drawable file as edittext_stroke.xml in drawable folder.
Add the below code:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line"
>
<stroke
android:width="1dp"
android:color="#android:color/white" >
</stroke>
</shape>
In layout file , add the drawable to edittext as
android:drawableBottom="#drawable/edittext_stroke"
<EditText
android:textColor="#android:color/white"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:drawableBottom="#drawable/edittext_stroke"
/>
Usually for similar tasks - I created layer-list drawable like this one:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#color/underlineColor"/>
</shape>
</item>
<item android:bottom="3dp">
<shape android:shape="rectangle">
<solid android:color="#color/buttonColor"/>
</shape>
</item>
The idea is that first you draw the rectangle with underlineColor and then on top of this one you draw another rectangle with the actual buttonColor but applying bottomPadding. It always works.
But when I needed to have buttonColor to be transparent I couldn't use the above drawable. I found one more solution
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#android:color/transparent"/>
</shape>
</item>
<item android:drawable="#drawable/white_box" android:gravity="bottom" android:height="2dp"/>
</layer-list>
(as you can see here the mainButtonColor is transparent and white_box is just a simple rectangle drawable with white Solid)
use this xml change the color with your choice.
<item>
<layer-list>
<item>
<shape>
<solid android:color="#color/gray_500" />
</shape>
</item>
<!-- CONTENT LAYER -->
<item android:bottom="2dp" >
<shape>
<solid android:color="#ffffff" />
</shape>
</item>
</layer-list>
</item>
In Case if you want programmatically
public static Drawable getStorkLineDrawable(#ColorInt int colorStrok, int iSize, int left, int top, int right, int bottom)
{
GradientDrawable gradientDrawable = new GradientDrawable();
gradientDrawable.setShape(GradientDrawable.RECTANGLE);
gradientDrawable.setStroke(iSize, colorStrok);
LayerDrawable layerDrawable = new LayerDrawable(new Drawable[]{gradientDrawable});
layerDrawable.setLayerInset(0, left, top, right, bottom);
return layerDrawable;
}
call this method like
Drawable yourLineDrawable= getStorkLineDrawable(yourColor, iSize, -iSize, -iSize, -iSize, 0);
easiest way to do this is put after that view where you want bottom border
<?xml version="1.0" encoding="utf-8"?>
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#color/colorPrimary" />
This worked best for me:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:top="-5dp" android:left="-5dp" android:right="-5dp" android:bottom="0dp">
<shape android:shape="rectangle">
<stroke android:width="4dp" android:color="#ff0000"/>
</shape>
</item>
</layer-list>
Shows the line on the bottom only. You can easily change with stroke width to size you like and also update the top, left, right on the accordingly.
Simply add -
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!--Minus (-) how much dp you gave in the stroke width from left right top-->
<item android:left="-10dp" android:right="-10dp" android:top="-10dp">
<shape
android:shape="rectangle">
<stroke
android:dashGap="10dp"
android:dashWidth="10dp"
android:width="10dp"
android:color="#android:color/holo_red_dark" />
<!--This is the main background -->
<solid android:color="#FFDDDDDD" />
</shape>
</item>
</layer-list>
Preview -
it is completely transparent Edittext with transparent background.
<item>
<shape android:shape="rectangle" >
<solid android:color="#color/transparent" />
</shape>
</item>
<item android:top="-3dp" android:right="-3dp" android:left="-3dp">
<shape>
<solid android:color="#android:color/transparent" />
<stroke
android:width="2dp"
android:color="#color/bottomline" />
</shape>
</item>
A Simple solution :
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:bottom="-1dp"
android:left="-1dp"
android:right="-1dp"
android:top="-1dp">
<shape android:shape="rectangle">
<solid android:color="#AARRGGBB" />
<stroke
android:width="5dp"
android:color="#android:color/red"
android:dashWidth="10dp"
android:dashGap="12dp" />
</shape>
</item>
</layer-list>
And finally we have something like that :)
This is rectangular background with bottom stroke
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<corners android:radius="4dp" />
<solid android:color="#f2f4f5" />
<stroke
android:width="3dp"
android:color="#002f34" />
<padding android:bottom="4dp" />
</shape>
</item>
<item>
<shape android:shape="rectangle">
<corners android:radius="4dp" />
<solid android:color="#f2f4f5" />
</shape>
</item>
</layer-list>
I'm able to draw border to a linear layout, but it is getting drawn on all sides. I want to restrict it to right side only, like you do in CSS (border-right:1px solid red;).
I've tried this, but it still draws on all sides:
<?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:height="2dp"
android:width="2dp"
android:color="#FF0000" />
<solid android:color="#000000" />
<padding
android:bottom="0dp"
android:left="0dp"
android:right="1dp"
android:top="0dp" />
<corners
android:bottomLeftRadius="0dp"
android:bottomRightRadius="5dp"
android:radius="1dp"
android:topLeftRadius="5dp"
android:topRightRadius="0dp" />
</shape>
</item>
Any suggestions on how to accomplish this?
BTW, I do not want to use the hack of putting a view of width 1dp on the required side.
You can use this to get border on one side
<?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">
<shape android:shape="rectangle">
<solid android:color="#000000" />
</shape>
</item>
</layer-list>
EDITED
As many including me wanted to have a one side border with transparent background, I have implemented a BorderDrawable which could give me borders with different size and color in the same way as we use css. But this could not be used via xml. For supporting XML, I have added a BorderFrameLayout in which your layout can be wrapped.
See my github for the complete source.
Easy as pie, allowing a transparent bg:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:angle="0"
android:startColor="#f00"
android:centerColor="#android:color/transparent"
android:centerX="0.01" />
</shape>
Change the angle to change border location:
0 = left
90 = bottom
180 = right
270 = top
it is also possible to implement what you want using a single layer
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:bottom="-5dp"
android:right="-5dp"
android:top="-5dp">
<shape android:shape="rectangle" >
<solid android:color="#color/color_of_the_background" />
<stroke
android:width="5dp"
android:color="#color/color_of_the_border" />
</shape>
</item>
</layer-list>
this way only left border is visible but you can achieve any combination you want by playing with bottom, left, right and top attributes of the item element
To get a border on just one side of a drawable, apply a negative inset to the other 3 sides (causing those borders to be drawn off-screen).
<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetTop="-2dp"
android:insetBottom="-2dp"
android:insetLeft="-2dp">
<shape android:shape="rectangle">
<stroke android:width="2dp" android:color="#FF0000" />
<solid android:color="#000000" />
</shape>
</inset>
This approach is similar to naykah's answer, but without the use of a layer-list.
An other great example
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetRight="-2dp">
<shape android:shape="rectangle">
<corners
android:bottomLeftRadius="4dp"
android:bottomRightRadius="0dp"
android:topLeftRadius="4dp"
android:topRightRadius="0dp" />
<stroke
android:width="1dp"
android:color="#70b23f" />
<solid android:color="#android:color/transparent" />
</shape>
</inset>
As an alternative (if you don't want to use background), you can easily do it by making a view as follows:
<View
android:layout_width="2dp"
android:layout_height="match_parent"
android:background="#000000" />
For having a right border only, place this after the layout (where you want to have the border):
<View
android:layout_width="2dp"
android:layout_height="match_parent"
android:background="#000000" />
For having a left border only, place this before the layout (where you want to have the border):
Worked for me...Hope its of some help....
I was able to achieve the effect 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="-5dp" android:top="-5dp" android:bottom="-5dp">
<shape
android:shape="rectangle">
<stroke android:width="1dp" android:color="#123456" />
</shape>
</item>
</layer-list>
You can adjust to your needs for border position by changing the direction of displacement
<?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="#f28b24" />
<stroke
android:width="1dp"
android:color="#f28b24" />
<corners
android:radius="0dp"/>
<padding
android:left="0dp"
android:top="0dp"
android:right="0dp"
android:bottom="0dp" />
</shape>
</item>
<item>
<shape>
<gradient
android:startColor="#f28b24"
android:endColor="#f28b24"
android:angle="270" />
<stroke
android:width="0dp"
android:color="#f28b24" />
<corners
android:bottomLeftRadius="8dp"
android:bottomRightRadius="0dp"
android:topLeftRadius="0dp"
android:topRightRadius="0dp"/>
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
</item>
</selector>
There is no mention about nine-patch files here. Yes, you have to create the file, however it's quite easy job and it's really "cross-version and transparency supporting" solution. If the file is placed to the drawable-nodpi directory, it works px based, and in the drawable-mdpi works approximately as dp base (thanks to resample).
Example file for the original question (border-right:1px solid red;) is here:
http://ge.tt/517ZIFC2/v/3?c
Just place it to the drawable-nodpi directory.
Borders of different colors. I used 3 items.
<?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/colorAccent" />
</shape>
</item>
<item android:top="3dp">
<shape android:shape="rectangle">
<solid android:color="#color/light_grey" />
</shape>
</item>
<item
android:bottom="1dp"
android:left="1dp"
android:right="1dp"
android:top="3dp">
<shape android:shape="rectangle">
<solid android:color="#color/colorPrimary" />
</shape>
</item>
</layer-list>
You can wrap into container and define margins for start left bottom top.
Suppose you want to provide margin for left side you can do this
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/light_blue"
>
<TextView
android:marginStart="2dp" // This is Your border
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/white"
android:padding="16dp"
android:text="a"
android:textColor="#color/light_blue"
android:textSize="25dp" />
</RelativeLayout>
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

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>
