I am trying to make a layout half transparent what I am trying is to make the red part transparent and the part which is not colored with strong color .I am able to set this with placing a black layer in the back of one layer but I want to make it half transparent like the red part will show the image placed in the back side how can I do this ?
this is the xml I tried
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="0.5dp"
android:color="#color/white" />
<corners
android:bottomLeftRadius="150dp"
android:bottomRightRadius="1000dp"
android:topLeftRadius="0dp"
android:topRightRadius="0dp" />
<padding
android:bottom="0dp"
android:left="0dp"
android:right="0dp"
android:top="0dp" />
<solid android:color="#color/red"
/>
So you have managed that curved shape I guess. To make this transparent, Use its color transparent instead of simple red color. Try following code with your xml.
<gradient
android:angle="45"
android:endColor="#aaF00"
android:centerColor="#aaF00"
android:startColor="#aaF00" />
So the whole file look like:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="0.5dp"
android:color="#color/white" />
<corners
android:bottomLeftRadius="150dp"
android:bottomRightRadius="1000dp"
android:topLeftRadius="0dp"
android:topRightRadius="0dp" />
<padding
android:bottom="0dp"
android:left="0dp"
android:right="0dp"
android:top="0dp" />
<gradient
android:angle="45"
android:endColor="#aa000000"
android:centerColor="#aa000000"
android:startColor="#aa000000" />
/>
I've added alpha to your red color. Refer this link for more information about alpha scale.
You can also visit this for exact information about colors and especially alpha scale to make color transparent.
Hope this will help you :)
You can put this shape drawable inside a layer-list drawable:
<?xml version="1.0" encoding="utf-8"?>
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- black background -->
<item android:drawable="#android:color/black"/>
<!-- red shape on top of black background -->
<item android:drawable="#drawable/curved_shape"/>
</layer-list>
Then use this layer-list drawable as your background.
Just place your layout inside one with black background.
<LinearLayout 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"
android:orientation="horizontal"
android:background="#000000">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:background="#drawable/your_shape">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!" />
</LinearLayout>
</LinearLayout>
Good afternoon,
I am doing an app who needs 3 buttons aligned under the TabLayout, like in the picture below :
I do not know what is the best way to do them, because each one has different borders.
Anyone can help me ?
Thank you !
I finally did it :
buttons.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"

android:layout_weight="1"
android:background="#drawable/button_shape_one" />
<Button

</shape>
Result :
Thank you all!
You need to create a Shape drawable for all of your buttons. For eg the center button can use below drawable as background.
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#606060"/>
<stroke android:color="#303030" android:width="2dp" />
</shape>
For the other two you need rounded edges only on left and right.For that you may follow This post on SO.
*Note: change the colors according to your needs and you will also require a selector to be applied on each button to highlight the selection.
The left and right borders can also be removed using shape drawable.For more details please see This post
The more easier approach will be to use This Library.
Set width to "0dp" and weight to "1" for all your buttons and wrap them inside a horizontal LinearLayout
roundedbuttons.xml in drawable
?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#ffffffff"/>
<stroke android:width="3dp"
android:color="#ff000000"
/>
<corners android:bottomRightRadius="7dp"
android:bottomLeftRadius="7dp"
android:topLeftRadius="7dp"
android:topRightRadius="7dp"/>
</shape>
Edit the shape according to your preference
In your xml layout
LinearLayout(Horizontal)
- Buttons with background(roundedbuttons.xml) and weight="1"
Why don't you use one linear layout with blue border as parent of 3 textViews with background. No need to make it complicated.
I want to create the shape of autocomplete textview shown in the figure and text should come in center of it.
Currently I am trying to implement it as
<item>
<shape android:shape="rectangle" >
<corners android:radius="15dip" />
<solid android:color="#color/blue_text" />
<padding
android:bottom="5dip"
android:left="15dip"
android:right="15dip"
android:top="5dip" />
</shape>
</item>
<AutoCompleteTextView
android:id="#+id/autoComp"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="center"
android:background="#drawable/bg_autocompletetext"
android:textColor="#color/white"
</AutoCompleteTextView>
But it would just make the corners of the textview round. It does make it completely round. Please specify any solution for it.
try this code of shape
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<corners
android:radius="100dp"/>
<solid
android:color="#2137FF"/>
<size
android:width="250dp"
android:height="60dp"/>
</shape>
try this tool
Its better to use 9 patch image as a background of your TextView.
With using 9 patch image you can set proper resolution for different resolution device.And it will give you better result .
You write a seperate xml layout(shape.xml) having code:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#DCDCDC" />
<stroke android:width="2.5dp"
android:color="#DCDCDC" />
<corners
android:radius="10dp"/>
</shape>
Then in your main layout add:
<AutoCompleteTextView
android:id="#+id/autoComp"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="center"
android:background="#drawable/shape"
android:textColor="#color/white"
</AutoCompleteTextView>
Hope this help.
Try this, working for rounded text view
<?xml version="1.0" encoding="utf-8"?>
<!-- res/drawable/rounded_textview.xml -->
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<solid android:color="#284A89" />
<corners
android:bottomLeftRadius="30dp"
android:bottomRightRadius="30dp"
android:topLeftRadius="30dp"
android:topRightRadius="30dp" />
</shape>
Add Following file in drawables "searchtextbox_border.xml"
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<corners
android:radius="100dp"/>
<stroke android:color="#color/light_grey"
android:width="1dp">
</stroke>
</shape>
Then Add it as background in your AutocompleteTextview as follows:
<AutoCompleteTextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="32dp"
android:padding="#dimen/padding_10dp"
android:background="#drawable/searchtextbox_border"
android:hint="Search" />
I need to draw a border to an imageview or a textview in my app, but I need to draw it only in one corner, like the image.
I do a shape but i get border in all 4 sides:
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="1px" android:color="#FF000000" />
<solid android:color="#ffffffff"/>
<padding android:left="1px" android:top="1px"
android:right="0px" android:bottom="0px" />
<corners android:topLeftRadius="8px" />
</shape>
How can I to do make it like in the image?
Thanks, Mattia
Use this code will solve it :
<?xml version="1.0" encoding="utf-8" ?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#FF0000" />
<corners android:topLeftRadius="15dp" />
</shape>
</item>
<item android:left="10dp" android:top="10dp">
<shape android:shape="rectangle">
<solid android:color="#000000" />
<corners android:topLeftRadius="15dp" />
</shape>
</item>
</layer-list>
you have to make adjustment in the ( layout Xml ) also as:
android:layout_width
android:layout_height
android:paddingTop
android:paddingLeft
this is the output :
hope this help.
This is how I achieved. Using inset drawable we can achieve this easily and more customization we can do with less code. Use this twoside_border.xml
<?xml version="1.0" encoding="UTF-8"?>
<!-- inset: It can remove border from any other side-->
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetBottom="-15dp"
android:insetRight="-15dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/rectangle">
<stroke
android:width="20dp"
android:color="#ED302F" />
<!--<corners
android:topLeftRadius="20dp"
/>-->
<!--<solid android:color="#f50a0a" />-->
</shape>
insetBottom & insetRight -dp values helps to hide the border where we do not need and as a output :
two side border image
to get corner curve remove the commented line in the above code
<corners android:topLeftRadius="20dp"/>
now we can see the curve bend
border with curve image
Use this xml in frame layout like below how I did & adjust the padding or margin according to your need, so that it fit inside the border image which look like a frame.
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingLeft="5dp"
android:paddingRight="5dp"
android:paddingTop="5dp"
android:scaleType="centerCrop"
android:src="#drawable/your_image_file" />
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/twoside_border" />
</FrameLayout>
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"

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: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);

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.
