I have a textview containing numbers 1,2,3.... I want to have a circle around the numbers, something along the lines of;
The code for my textview is;
<TextView
android:id="#+id/position"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_weight="0.20"
android:textStyle="bold"
android:layout_gravity="center"
android:layout_margin="5dp"
android:background="#drawable/circlebg"
android:textSize="20dp"/>
and I have a xml background file, which contains;
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<corners android:radius="10dip"/>
<stroke android:color="#ff0000" android:width="2dip"/>
<solid android:color="#android:color/transparent"/>
</shape>
the outcome of this is;
What I want to know is how can I get the result of this to be like shown in the first screenshot. Any help is welcomed.
activity.xml
<Button
android:id="#+id/fragment_pos_inventory_Add"
android:layout_width="25dp"
android:layout_height="25dp"
android:background="#drawable/layer_list" />
layer_list.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="false">
<shape android:shape="oval">
<solid android:color="#fa09ad" />

</item>
<item android:state_pressed="true">
<shape android:shape="oval">
<solid android:color="#ffffff"/>
<padding android:left="2dp"

android:bottom="2dp"/>
</shape>
</item>
</layer-list>
Have you tried ViewBadger or BadgeView? These may help you. You can later make changes on that.
You are on the right track, all you have to do is make the textview's layout_height and layout_width a fixed value e.g 50dp, instead of using "wrap_content". When the textView's layout_height and layout_width are equal, you get a circle.
I want to create a custom View based on ImageView to make a widget as below where the drawable source is the camera and the background is the rectangle with the tick sign:
The problems are:
I can not create the border with the tick sign on the right: the tick is stretched fullscreen instead of staying at the bottom right.
The tick sign is sometime behind the image if I set it with android:background.
Here are my xml files:

Thanks for your time.
I'm not sure if this is the sort of solution you'd be looking for but instead of having an xml file with the styling in it, I believe it would be better to have a layout file which defines your layout for your custom Widget, Something like this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/customWidgetBox"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/customCheckmark"
android:gravity="bottom|right" />
</LinearLayout>
And to the drawable folder you would need to add both the customCheckmark.xml and customWidgetBox.xml
customCheckmark.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<item android:drawable="#drawable/check_mark">
<stroke android:width="3dp" android:color="#color/blue_button_border" />
</item>
</shape>
customWidgetBox.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<item android:drawable="#drawable/camera">
<stroke android:width="3dp" android:color="#color/blue_button_border" />
</item>
</shape>
Not sure if this code accomplish exactly what you want, but it'll be a good help to get you started because this is definitely the way to do it! :)

how to put a border around an android textview
Tips & Tricks -XML Drawables Part 1
I have a textview and want its corner to be in round shape. I already know it can be done using android:background="#drawable/somefile". In my case, this tag is already included so cannot use again. e.g android:background="#drawable/mydialogbox" is already there to create image in background
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_gravity="top"
android:background="#drawable/mydialogbox"
android:orientation="horizontal" >
<TextView
android:id="#+id/textview_name"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
</LinearLayout>
</RelativeLayout>
so when I want textview(textview_name) also with round corner, how this can be achieved.
Create rounded_corner.xml in the drawable folder and add the following content,
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<stroke
android:width="1dp"
android:color="#color/common_border_color" />
<solid android:color="#ffffff" />
<padding
android:left="1dp"
android:right="1dp"
android:bottom="1dp"
android:top="1dp" />
<corners android:radius="5dp" />
</shape>
Set this drawable in the TextView background property like so:
android:background="#drawable/rounded_corner"
I hope this is useful for you.
Beside radius, there are some property to round corner like topRightRadius, topLeftRadius, bottomRightRadius, bottomLeftRadius
Example TextView with red border with corner and gray background
bg_rounded.xml (in the drawables folder)
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke
android:width="10dp"
android:color="#f00" />
<solid android:color="#aaa" />
<corners
android:radius="5dp"
android:topRightRadius="100dp" />
</shape>
TextView
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/bg_rounded"
android:text="Text"
android:padding="20dp"
android:layout_margin="10dp"
/>
Result
With the Material Components Library you can use the MaterialShapeDrawable.
With a TextView:
<TextView
android:id="#+id/textview"
../>
You can programmatically apply a MaterialShapeDrawable:
float radius = getResources().getDimension(R.dimen.corner_radius);
TextView textView = findViewById(R.id.textview);
ShapeAppearanceModel shapeAppearanceModel = new ShapeAppearanceModel()
.toBuilder()
.setAllCorners(CornerFamily.ROUNDED,radius)
.build();
MaterialShapeDrawable shapeDrawable = new MaterialShapeDrawable(shapeAppearanceModel);
ViewCompat.setBackground(textView,shapeDrawable);
If you want to change the background color and the border just apply:
shapeDrawable.setFillColor(ContextCompat.getColorStateList(this,R.color.....));
shapeDrawable.setStroke(2.0f, ContextCompat.getColor(this,R.color....));
Since your top level view already has android:background property set, you can use a <layer-list> (link) to create a new XML drawable that combines both your old background and your new rounded corners background.
Each <item> element in the list is drawn over the next, so the last item in the list is the one that ends up on top.
<?xml version="1.0" encoding="utf-8"?>
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<bitmap android:src="#drawable/mydialogbox" />
</item>
<item>
<shape>
<stroke
android:width="1dp"
android:color="#color/common_border_color" />
<solid android:color="#ffffff" />
<padding
android:left="1dp"
android:right="1dp"
android:top="1dp" />
<corners android:radius="5dp" />
</shape>
</item>
</layer-list>
There is Two steps
1) Create this file in your drawable folder :- rounded_corner.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="10dp" /> // set radius of corner
<stroke android:width="2dp" android:color="#ff3478" /> // set color and width of border
<solid android:color="#FFFFFF" /> // inner bgcolor
</shape>
2) Set this file into your TextView as background property.
android:background="#drawable/rounded_corner"
You can use this drawable in Button or Edittext also
create an xml gradient.xml file under drawable folder
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle" >
<corners android:radius="50dip" />
<stroke android:width="1dip" android:color="#667162" />
<gradient android:angle="-90" android:startColor="#ffffff" android:endColor="#ffffff" />
</shape>
</item>
</selector>
then add this to your TextView
android:background="#drawable/gradient"
You can use the provided rectangle shape (without a gradient, unless you want one) as follows:
In drawable/rounded_rectangle.xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="5dp" />
<stroke android:width="1dp" android:color="#ff0000" />
<solid android:color="#00ff00" />
</shape>
Then in your text view:
android:background="#drawable/rounded_rectangle"
Of course, you will want to customize the dimensions and colors.
Right Click on Drawable Folder and Create new File
Name the file according to you and add the extension as .xml.
Add the following code in the file
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="5dp" />
<stroke android:width="1dp" />
<solid android:color="#1e90ff" />
</shape>
Add the line where you want the rounded edge android:background="#drawable/corner"
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/background">
<shape>
<corners android:radius="5dp" />
<solid android:color="#ffffff"/>
</shape>
</item>
</layer-list>
Put your TextView inside MaterialCardView:
<com.google.android.material.card.MaterialCardView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:cardCornerRadius="25dp"
>
<com.google.android.material.textview.MaterialTextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/emergency_sms_template"
android:padding="6dp"
android:textSize="11sp"
/>
</com.google.android.material.card.MaterialCardView>
You can use SVG for rounding corners and load into an ImageView and use ConstraintLayout to bring ImageView on TextView
I used it for rounded ImageView and rounded TextView
Simply using an rounded corner image as the background of that view
And don't forget to have your custom image in drawable folder
android:background="#drawable/my_custom_image"
I have a TextView and I'd like to add a black border along its top and bottom borders. I tried adding android:drawableTop and android:drawableBottom to the TextView, but that only caused the entire view to become black.
<TextView
android:background="#android:color/green"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:drawableTop="#android:color/black"
android:drawableBottom="#android:color/black"
android:text="la la la" />
Is there a way to easily add a top and bottom border to a View (in particular, a TextView) in Android?
In android 2.2 you could do the following.
Create an xml drawable such as /res/drawable/textlines.xml and assign this as a TextView's background property.
<TextView
android:text="My text with lines above and below"
android:background="#drawable/textlines"
/>
/res/drawable/textlines.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="#FFDDDDDD" />
<solid android:color="#00000000" />
</shape>
</item>
</layer-list>
The down side to this is that you have to specify an opaque background colour, as transparencies won't work. (At least i thought they did but i was mistaken). In the above example you can see that the solid colour of the first shape #FFdddddd is copied in the 2nd shapes stroke colour.
I've used a trick so that the border is displayed outside the container. With this trick only a line is drawn so the background will be shown of the underlying view.
<?xml version="1.0" encoding="utf-8"?>
<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="1dp"
android:color="#FF000000" />
<solid android:color="#00FFFFFF" />
<padding android:left="10dp"
android:right="10dp"
android:top="10dp"
android:bottom="10dp" />
</shape>
</item>
</layer-list>
To add a 1dp white border at the bottom only and to have a transparent background you can use the following which is simpler than most answers here.
For the TextView or other view add:
android:background="#drawable/borderbottom"
And in the drawable directory add the following XML, called borderbottom.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:top="-2dp" android:left="-2dp" android:right="-2dp">
<shape android:shape="rectangle">
<stroke android:width="1dp" android:color="#ffffffff" />
<solid android:color="#00000000" />
</shape>
</item>
</layer-list>
If you want a border at the top, change the android:top="-2dp" to android:bottom="-2dp"
The colour does not need to be white and the background does not need to be transparent either.
The solid element may not be required. This will depend on your design (thanks V. Kalyuzhnyu).
Basically, this XML will create a border using the rectangle shape, but then pushes the top, right and left sides beyond the render area for the shape. This leaves just the bottom border visible.
Option 1: Shape Drawable
This is the simplest option if you want a border around a layout or view in which you can set the background. Create an XML file in the drawable folder that looks something like this:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#8fff93" />
<stroke
android:width="1px"
android:color="#000" />
</shape>
You can remove the solid if you don't want a fill. The set background="#drawable/your_shape_drawable" on your layout/view.
Option 2: Background View
Here's a little trick I've used in a RelativeLayout. Basically you have a black square under the view you want to give a border, and then give that view some padding (not margin!) so the black square shows through at the edges.
Obviously this only works properly if the view doesn't have any transparent areas. If it does I would recommend you write a custom BorderView which only draws the border - it should only be a few dozen lines of code.
<View
android:id="#+id/border"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/image"
android:layout_alignLeft="#+id/image"
android:layout_alignRight="#+id/image"
android:layout_alignTop="#+id/main_image"
android:background="#000" />
<ImageView
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_...
android:padding="1px"
android:src="#drawable/..." />
If you're wondering, it does work with adjustViewBounds=true. However, it doesn't work if you want to have a background in an entire RelativeLayout, because there is a bug that stops you filling a RelativeLayout with a View. In that case I'd recommend the Shape drawable.
Option 3: 9-patch
A final option is to use a 9-patch drawable like this one:
You can use it on any view where you can set android:background="#drawable/...". And yes it does need to be 6x6 - I tried 5x5 and it didn't work.
The disadvantage of this method is you can't change the colours very easily, but if you want fancy borders (e.g. only a border at the top and bottom, as in this question) then you may not be able to do them with the Shape drawable, which isn't very powerful.
Option 4: Extra views
I forgot to mention this really simple option if you only want borders above and below your view. You can put your view in a vertical LinearLayout (if it isn't already) and then add empty Views above and below it like this:
<View android:background="#000" android:layout_width="match_parent" android:layout_height="1px"/>
The currently accepted answer doesn't work. It creates thin vertical borders on the left and right sides of the view as a result of anti-aliasing.
This version works perfectly. It also allows you to set the border widths independently, and you can also add borders on the left / right sides if you want. The only drawback is that it does NOT support transparency.
Create an xml drawable named /res/drawable/top_bottom_borders.xml with the code below and assign it as a TextView's background property.
<?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="#DDDD00" /> <!-- border color -->
</shape>
</item>
<item
android:bottom="1dp"
android:top="1dp"> <!-- adjust borders width here -->
<shape android:shape="rectangle">
<solid android:color="#FFFFFF" /> <!-- background color -->
</shape>
</item>
</layer-list>
Tested on Android KitKat through Marshmallow
So I wanted to do something slightly different: a border on the bottom ONLY, to simulate a ListView divider. I modified Piet Delport's answer and got 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/background_trans_light" />
</shape>
</item>
<!-- this mess is what we have to do to get a bottom border only. -->
<item android:top="-2dp"
android:left="-2dp"
android:right="-2dp"
android:bottom="1px">
<shape
android:shape="rectangle">
<stroke android:width="1dp" android:color="#color/background_trans_mid" />
<solid android:color="#null" />
</shape>
</item>
</layer-list>
Note using px instead of dp to get exactly 1 pixel divider (some phone DPIs will make a 1dp line disappear).
Add file to res/drawable
<?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="1dp"
android:color="#000000" />
</shape>
</item>
</layer-list>
Add link on this file to background property
Just as #Nic Hubbard said, there is a very easy way to add a border line.
<View
android:layout_width="match_parent"
android:layout_height="2dp"
android:background="#000000" >
</View>
You can change the height and background color to whatever you want.
You can also wrap the view in a FrameLayout, then set the frame's background color and padding to what you want; however, the textview, by default has a 'transparent' background, so you'd need to change the textview's background color too.
My answers is based on #Emile version but I use transparent color instead of solid.
This example will draw a 2dp bottom border.
<?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="2dp"
android:color="#50C0E9" />
<solid android:color="#android:color/transparent" />
</shape>
</item>
<item android:bottom="2dp" >
<shape android:shape="rectangle" >
<stroke android:width="2dp"
android:color="#color/bgcolor" />
<solid android:color="#android:color/transparent" />
</shape>
</item>
</layer-list>
#color/bgcolor is the color of the background on wich you draw your view with border.
If you want to change the position of the border change the offset with one of:
android:bottom="2dp"
android:top="2dp"
android:right="2dp"
android:left="2dp"
or combine them to have 2 or more borders:
android:bottom="2dp" android:top="2dp"
You can do this by this code snippet -
<?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-->
<item android:left="-10dp" android:right="-10dp">
<shape
android:shape="rectangle">
<stroke android:width="10dp" android:color="#android:color/holo_red_dark" />
<!--This is the main background -->
<solid android:color="#FFDDDDDD" />
</shape>
</item>
</layer-list>
Preview -
Why not just create a 1dp high view with a background color? Then it can be easily placed where you want.
To change this:
<TextView
android:text="My text"
android:background="#drawable/top_bottom_border"/>
I prefer this approach in "drawable/top_bottom_border.xml":
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<gradient
android:angle="270"
android:startColor="#000"
android:centerColor="#android:color/transparent"
android:centerX="0.01" />
</shape>
</item>
<item>
<shape>
<gradient
android:angle="90"
android:startColor="#000"
android:centerColor="#android:color/transparent"
android:centerX="0.01" />
</shape>
</item>
</layer-list>
This only makes the borders, not a rectangle that will appear if your background has a color.
Simplest way to add borders to inset the borders using InsetDrawable,following will show top border only :
<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetBottom="-2dp"
android:insetLeft="-2dp"
android:insetRight="-2dp">
<shape android:shape="rectangle">
<solid android:color="#color/light_gray" />
<stroke
android:width=".5dp"
android:color="#color/dark_gray" />
</shape>
</inset>
Just to add my solution to the list..
I wanted a semi transparent bottom border that extends past the original shape (So the semi-transparent border was outside the parent rectangle).
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle" >
<solid android:color="#33000000" /> <!-- Border colour -->
</shape>
</item>
<item android:bottom="2dp" >
<shape android:shape="rectangle" >
<solid android:color="#164586" />
</shape>
</item>
</layer-list>
Which gives me;
First make a xml file with contents shown below and name it border.xml and place it inside the layout folder inside the res directory
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="1dp" android:color="#0000" />
<padding android:left="0dp" android:top="1dp" android:right="0dp"
android:bottom="1dp" />
</shape>
After that inside the code use
TextView tv = (TextView)findElementById(R.id.yourTextView);
tv.setBackgroundResource(R.layout.border);
This will make a black line on top and bottom of the TextView.
Simply add Views at the top and bottom of the View
<?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="match_parent"
android:layout_height="1dp"
android:background="#color/your_color"
app:layout_constraintBottom_toTopOf="#+id/textView"
app:layout_constraintEnd_toEndOf="#+id/textView"
app:layout_constraintStart_toStartOf="#+id/textView" />
<TextView
android:id="#+id/textView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginTop="32dp"
android:gravity="center"
android:text="Testing"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#color/your_color"
app:layout_constraintEnd_toEndOf="#+id/textView"
app:layout_constraintStart_toStartOf="#+id/textView"
app:layout_constraintTop_toBottomOf="#+id/textView" />
</android.support.constraint.ConstraintLayout>
Write down below code
<View
android:layout_width="wrap_content"
android:layout_height="2dip"
android:layout_below="#+id/topics_text"
android:layout_marginTop="7dp"
android:layout_margin="10dp"
android:background="#ffffff" />
Try wrapping the image with a linearlayout, and set it's background to the border color you want around the text. Then set the padding on the textview to be the thickness you want for your border.
You can also use a 9-path to do your job. Create it so that colored pixel do not multiply in height but only the transparent pixel.
Based on accepted answer of Pi Delport and Emile, I made it a little simpler

Just Add this TextView below the text where you want to add the border
Just to enforce #phreakhead ´s and user1051892 ´s answers, <item android:bottom|android:left|android:right|android:top> if negative, must to be greater than <stroke android:width>. If not, item´s painting will be mixed with stroke´s painting and you may think these values are not working.
I have a TextView and I'd like to add a black border along its top and bottom borders. I tried adding android:drawableTop and android:drawableBottom to the TextView, but that only caused the entire view to become black.
<TextView
android:background="#android:color/green"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:drawableTop="#android:color/black"
android:drawableBottom="#android:color/black"
android:text="la la la" />
Is there a way to easily add a top and bottom border to a View (in particular, a TextView) in Android?
In android 2.2 you could do the following.
Create an xml drawable such as /res/drawable/textlines.xml and assign this as a TextView's background property.
<TextView
android:text="My text with lines above and below"
android:background="#drawable/textlines"
/>
/res/drawable/textlines.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="#FFDDDDDD" />
<solid android:color="#00000000" />
</shape>
</item>
</layer-list>
The down side to this is that you have to specify an opaque background colour, as transparencies won't work. (At least i thought they did but i was mistaken). In the above example you can see that the solid colour of the first shape #FFdddddd is copied in the 2nd shapes stroke colour.
I've used a trick so that the border is displayed outside the container. With this trick only a line is drawn so the background will be shown of the underlying view.
<?xml version="1.0" encoding="utf-8"?>
<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="1dp"
android:color="#FF000000" />
<solid android:color="#00FFFFFF" />
<padding android:left="10dp"
android:right="10dp"
android:top="10dp"
android:bottom="10dp" />
</shape>
</item>
</layer-list>
To add a 1dp white border at the bottom only and to have a transparent background you can use the following which is simpler than most answers here.
For the TextView or other view add:
android:background="#drawable/borderbottom"
And in the drawable directory add the following XML, called borderbottom.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:top="-2dp" android:left="-2dp" android:right="-2dp">
<shape android:shape="rectangle">
<stroke android:width="1dp" android:color="#ffffffff" />
<solid android:color="#00000000" />
</shape>
</item>
</layer-list>
If you want a border at the top, change the android:top="-2dp" to android:bottom="-2dp"
The colour does not need to be white and the background does not need to be transparent either.
The solid element may not be required. This will depend on your design (thanks V. Kalyuzhnyu).
Basically, this XML will create a border using the rectangle shape, but then pushes the top, right and left sides beyond the render area for the shape. This leaves just the bottom border visible.
Option 1: Shape Drawable
This is the simplest option if you want a border around a layout or view in which you can set the background. Create an XML file in the drawable folder that looks something like this:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#8fff93" />
<stroke
android:width="1px"
android:color="#000" />
</shape>
You can remove the solid if you don't want a fill. The set background="#drawable/your_shape_drawable" on your layout/view.
Option 2: Background View
Here's a little trick I've used in a RelativeLayout. Basically you have a black square under the view you want to give a border, and then give that view some padding (not margin!) so the black square shows through at the edges.
Obviously this only works properly if the view doesn't have any transparent areas. If it does I would recommend you write a custom BorderView which only draws the border - it should only be a few dozen lines of code.
<View
android:id="#+id/border"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/image"
android:layout_alignLeft="#+id/image"
android:layout_alignRight="#+id/image"
android:layout_alignTop="#+id/main_image"
android:background="#000" />
<ImageView
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_...
android:padding="1px"
android:src="#drawable/..." />
If you're wondering, it does work with adjustViewBounds=true. However, it doesn't work if you want to have a background in an entire RelativeLayout, because there is a bug that stops you filling a RelativeLayout with a View. In that case I'd recommend the Shape drawable.
Option 3: 9-patch
A final option is to use a 9-patch drawable like this one:
You can use it on any view where you can set android:background="#drawable/...". And yes it does need to be 6x6 - I tried 5x5 and it didn't work.
The disadvantage of this method is you can't change the colours very easily, but if you want fancy borders (e.g. only a border at the top and bottom, as in this question) then you may not be able to do them with the Shape drawable, which isn't very powerful.
Option 4: Extra views
I forgot to mention this really simple option if you only want borders above and below your view. You can put your view in a vertical LinearLayout (if it isn't already) and then add empty Views above and below it like this:
<View android:background="#000" android:layout_width="match_parent" android:layout_height="1px"/>
The currently accepted answer doesn't work. It creates thin vertical borders on the left and right sides of the view as a result of anti-aliasing.
This version works perfectly. It also allows you to set the border widths independently, and you can also add borders on the left / right sides if you want. The only drawback is that it does NOT support transparency.
Create an xml drawable named /res/drawable/top_bottom_borders.xml with the code below and assign it as a TextView's background property.
<?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="#DDDD00" /> <!-- border color -->
</shape>
</item>
<item
android:bottom="1dp"
android:top="1dp"> <!-- adjust borders width here -->
<shape android:shape="rectangle">
<solid android:color="#FFFFFF" /> <!-- background color -->
</shape>
</item>
</layer-list>
Tested on Android KitKat through Marshmallow
So I wanted to do something slightly different: a border on the bottom ONLY, to simulate a ListView divider. I modified Piet Delport's answer and got 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/background_trans_light" />
</shape>
</item>
<!-- this mess is what we have to do to get a bottom border only. -->
<item android:top="-2dp"
android:left="-2dp"
android:right="-2dp"
android:bottom="1px">
<shape
android:shape="rectangle">
<stroke android:width="1dp" android:color="#color/background_trans_mid" />
<solid android:color="#null" />
</shape>
</item>
</layer-list>
Note using px instead of dp to get exactly 1 pixel divider (some phone DPIs will make a 1dp line disappear).
Add file to res/drawable
<?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="1dp"
android:color="#000000" />
</shape>
</item>
</layer-list>
Add link on this file to background property
Just as #Nic Hubbard said, there is a very easy way to add a border line.
<View
android:layout_width="match_parent"
android:layout_height="2dp"
android:background="#000000" >
</View>
You can change the height and background color to whatever you want.
You can also wrap the view in a FrameLayout, then set the frame's background color and padding to what you want; however, the textview, by default has a 'transparent' background, so you'd need to change the textview's background color too.
My answers is based on #Emile version but I use transparent color instead of solid.
This example will draw a 2dp bottom border.
<?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="2dp"
android:color="#50C0E9" />
<solid android:color="#android:color/transparent" />
</shape>
</item>
<item android:bottom="2dp" >
<shape android:shape="rectangle" >
<stroke android:width="2dp"
android:color="#color/bgcolor" />
<solid android:color="#android:color/transparent" />
</shape>
</item>
</layer-list>
#color/bgcolor is the color of the background on wich you draw your view with border.
If you want to change the position of the border change the offset with one of:
android:bottom="2dp"
android:top="2dp"
android:right="2dp"
android:left="2dp"
or combine them to have 2 or more borders:
android:bottom="2dp" android:top="2dp"
You can do this by this code snippet -
<?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-->
<item android:left="-10dp" android:right="-10dp">
<shape
android:shape="rectangle">
<stroke android:width="10dp" android:color="#android:color/holo_red_dark" />
<!--This is the main background -->
<solid android:color="#FFDDDDDD" />
</shape>
</item>
</layer-list>
Preview -
Why not just create a 1dp high view with a background color? Then it can be easily placed where you want.
To change this:
<TextView
android:text="My text"
android:background="#drawable/top_bottom_border"/>
I prefer this approach in "drawable/top_bottom_border.xml":
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<gradient
android:angle="270"
android:startColor="#000"
android:centerColor="#android:color/transparent"
android:centerX="0.01" />
</shape>
</item>
<item>
<shape>
<gradient
android:angle="90"
android:startColor="#000"
android:centerColor="#android:color/transparent"
android:centerX="0.01" />
</shape>
</item>
</layer-list>
This only makes the borders, not a rectangle that will appear if your background has a color.
Simplest way to add borders to inset the borders using InsetDrawable,following will show top border only :
<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetBottom="-2dp"
android:insetLeft="-2dp"
android:insetRight="-2dp">
<shape android:shape="rectangle">
<solid android:color="#color/light_gray" />
<stroke
android:width=".5dp"
android:color="#color/dark_gray" />
</shape>
</inset>
Just to add my solution to the list..
I wanted a semi transparent bottom border that extends past the original shape (So the semi-transparent border was outside the parent rectangle).
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle" >
<solid android:color="#33000000" /> <!-- Border colour -->
</shape>
</item>
<item android:bottom="2dp" >
<shape android:shape="rectangle" >
<solid android:color="#164586" />
</shape>
</item>
</layer-list>
Which gives me;
First make a xml file with contents shown below and name it border.xml and place it inside the layout folder inside the res directory
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="1dp" android:color="#0000" />
<padding android:left="0dp" android:top="1dp" android:right="0dp"
android:bottom="1dp" />
</shape>
After that inside the code use
TextView tv = (TextView)findElementById(R.id.yourTextView);
tv.setBackgroundResource(R.layout.border);
This will make a black line on top and bottom of the TextView.
Simply add Views at the top and bottom of the View
<?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="match_parent"
android:layout_height="1dp"
android:background="#color/your_color"
app:layout_constraintBottom_toTopOf="#+id/textView"
app:layout_constraintEnd_toEndOf="#+id/textView"
app:layout_constraintStart_toStartOf="#+id/textView" />
<TextView
android:id="#+id/textView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginTop="32dp"
android:gravity="center"
android:text="Testing"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#color/your_color"
app:layout_constraintEnd_toEndOf="#+id/textView"
app:layout_constraintStart_toStartOf="#+id/textView"
app:layout_constraintTop_toBottomOf="#+id/textView" />
</android.support.constraint.ConstraintLayout>
Write down below code
<View
android:layout_width="wrap_content"
android:layout_height="2dip"
android:layout_below="#+id/topics_text"
android:layout_marginTop="7dp"
android:layout_margin="10dp"
android:background="#ffffff" />
Try wrapping the image with a linearlayout, and set it's background to the border color you want around the text. Then set the padding on the textview to be the thickness you want for your border.
You can also use a 9-path to do your job. Create it so that colored pixel do not multiply in height but only the transparent pixel.
Based on accepted answer of Pi Delport and Emile, I made it a little simpler
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item> <!--divider TOP and BOTTOM-->
<shape android:shape="rectangle">
<stroke
android:width="1dp"
android:color="#color/divider" />
</shape>
</item>
<!--background surface-->
<item
android:top="1dp"
android:bottom="1dp">
<shape android:shape="rectangle">
<solid android:color="#color/background" />
</shape>
</item>
// Just simply add border around the image view or view
<ImageView
android:id="#+id/imageView2"
android:layout_width="90dp"
android:layout_height="70dp"
android:layout_centerVertical="true"
android:layout_marginRight="10dp"
android:layout_toLeftOf="#+id/imageView1"
android:background="#android:color/white"
android:padding="5dip" />
// After that dynamically put color into your view or image view object
objView.setBackgroundColor(Color.GREEN);
//VinodJ/Abhishek
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#color/light_grey1" />
<stroke
android:width="1dip"
android:color="#color/light_grey1" />
<corners
android:bottomLeftRadius="0dp"
android:bottomRightRadius="0dp"
android:topLeftRadius="5dp"
android:topRightRadius="5dp" />
</shape>
<TextView
android:id="#+id/textView3"
android:layout_width="match_parent"
android:layout_height="2dp"
android:background="#72cdf4"
android:text=" aa" />
Just Add this TextView below the text where you want to add the border
Just to enforce #phreakhead ´s and user1051892 ´s answers, <item android:bottom|android:left|android:right|android:top> if negative, must to be greater than <stroke android:width>. If not, item´s painting will be mixed with stroke´s painting and you may think these values are not working.
