I have a shape with a gradient that I'm using as a divider between ListView items. I've defined it as follows:
<?xml version="1.0" encoding="UTF-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#ccd0d3"
android:centerColor="#b6babd"
android:endColor="#ccd0d3"
android:height="1px"
android:angle="0" />
</shape>
I would like to add 6 pixels of padding on either side of the gradient, so that it doesn't extend from edge to edge of the screen.
However, no matter where I put an android:left="6px" and android:right="6px", it doesn't seem to take effect. I can put it in the <shape> element, the <gradient> element, or in a separate <padding> child of <shape>, and it doesn't change anything.
How can I add padding on the left and right of my list divider?
I guess you could combine it like this:
<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:left="6dp"
android:right="6dp">
<shape android:shape="rectangle">
<gradient android:startColor="#ccd0d3"
android:centerColor="#b6babd"
android:endColor="#ccd0d3"
android:height="1px"
android:angle="0"/>
</shape>
</item>
</layer-list>
Another solution using inset:
<?xml version="1.0" encoding="UTF-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetLeft="6dp"
android:insetRight="6dp" >
<shape
android:shape="rectangle">
<gradient
android:startColor="#ccd0d3"
android:centerColor="#b6babd"
android:endColor="#ccd0d3"
android:height="1px"
android:angle="0" />
</shape>
</inset>
One solution seems to be to "wrap" my drawable with another drawable that specifies the appropriate padding.
For example, list_divider.xml would be:
<?xml version="1.0" encoding="UTF-8"?>
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:left="6dp"
android:right="6dp"
android:drawable="#drawable/list_divider_inner" />
</layer-list>
And then list_divider_inner.xml would be the original drawable:
<?xml version="1.0" encoding="UTF-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#ccd0d3"
android:centerColor="#b6babd"
android:endColor="#ccd0d3"
android:height="1px"
android:angle="0" />
</shape>
This results in two files to specify a simple divider though. I don't know if there's a way to do it with only one file though.

when creating a background with a gradient, it is possible to set the gradient in multiplications of 45
how can I set the gradient angle to 60 for instance?
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<gradient
android:angle="45"
android:startColor="#color/gradient_bottom"
android:endColor="#color/gradient_top"
android:type="linear" />
</shape>
</item>
</selector>
You can use like this.
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle"
>
<gradient
android:startColor="#color/purple"
android:endColor="#color/pink"
android:angle="60" />
</shape>
If you use shape then it's working fine.
I need to create a round corner border, where border with gradient.enter link description here is working.But My page is using a image as background which is also with gradient. I need to show background image from middle of the filed. I want to create just like below image:
round_background.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="4dp"
android:color="#color/transparent" />
<gradient
android:startColor="#374533"
android:centerColor="#432727"
android:endColor="#222430"
android:angle="135"/>
<corners android:radius="10dp" />
</shape>
round_border.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:startColor="#efe301"
android:centerColor="#7dc17b"
android:endColor="#01dae6"
android:angle="180"/>
<corners android:radius="10dp" />
result_drawable.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/round_border"/>
<item android:drawable="#drawable/round_background" />
</layer-list>
Here, you can set android:width="4dp" in round_background.xml to set size of your border. use result result_drawable.xml where you want..
Enjoy. :}
I am using the following xml code to show smooth top white strip and bottom white strip on list item selection. The problem is that it shows gradient on list item selection.I think, I am missing something in xml,Please help me.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<gradient
android:startColor="#android:color/white"
android:centerColor="#android:color/transparent"
android:endColor="#android:color/white"
android:angle="90" />
</shape>
</item>
</selector>
<!-- If you simply want a background for your list item, use the following -->
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle"><stroke android:color="#color/popup_border" android:width="1dp"/> <!-- For border/outline(Remove this line if you don't want border/outline)-->
<gradient android:startColor="#android:color/white" android:centerColor="#android:color/transparent" android:endColor="#android:color/white" android:angle="270" />
</shape>
</item>
</selector>
Essentially, I am trying to create the following background:
The traditional gradient which use in the drawable that I use for background only supports start color, middle color and end color.
However, as you can see from the mockup, I am trying to create only a slight overlay/shadow at the top and bottom of the shape, with a #50000000 color (black with 50% opacity).
If you're using this inside a Layout view, then you can simply create a View with a gradient background and place it in the beginning and in the end of the Layout.
For example:
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/parent">
<View
android:layout_width="fill_parent"
android:layout_height="5dp"
android:background="#drawable/gradient" />
<!-- Your other child views -->
<View
android:layout_width="fill_parent"
android:layout_height="5dp"
android:background="#drawable/gradient" />
</LinearLayout>
And your gradient.xml file will have this:
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient android:startColor="#FFFFFF" android:endColor="#000000" android:angle="90"/>
</shape>
You can specify the blue background color to the parent layout.
You'll essentially get something like this:
[EDIT]
You can create two drawables - gradient_top.xml and gradient_bottom.xml to get the angle right
I prefer doing this than having to mess around with 9-Patches. Although, having said that, I wish Google would get on with providing built-in support for drop shadows, since they're so common.
Just to build on JoelFernandez solution with a more complete example:
The Container:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="[your_container_height]"
android:background="#drawable/container_bg_color">
<View
android:layout_width="match_parent"
android:layout_height="12dp"
android:layout_alignParentTop="true"
android:background="#drawable/container_gradient_top"/>
<View
android:layout_width="match_parent"
android:layout_height="12dp"
android:layout_alignParentBottom="true"
android:background="#drawable/container_gradient_bottom" />
<!-- Insert your content here -->
</RelativeLayout>
The Background Color (container_bg_color.xml):
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:thickness="0dp"
android:shape="rectangle">
<gradient android:startColor="#4a6fb4"
android:endColor="#color/deepBlue"
android:angle="135"/>
</shape>
The Top Gradient (container_gradient_top.xml):
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:thickness="0dp"
android:shape="rectangle">
<gradient
android:startColor="#00222222"
android:centerColor="#11111111"
android:endColor="#44000000"
android:angle="90"/>
</shape>
The Bottom Gradient (container_gradient_bottom.xml):
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:thickness="0dp"
android:shape="rectangle">
<gradient
android:startColor="#44000000"
android:centerColor="#11111111"
android:endColor="#00222222"
android:angle="90"/>
</shape>
Result:
Elaborating #ramaral's answer, build this drawable:
<?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="#FF408DAA"/>
</shape>
</item>
<item android:top="0dip" android:bottom="32dip">
<shape android:shape="rectangle">
<gradient android:startColor="#00000000" android:endColor="#50000000" android:angle="90"/>
</shape>
</item>
<item android:top="32dip" android:bottom="0dip">
<shape android:shape="rectangle">
<gradient android:startColor="#50000000" android:endColor="#00000000" android:angle="90"/>
</shape>
</item>
</layer-list>
You would need to set a fixed height in the view, in order to achieve the best result. In my case I was setting the height to "36dip". Notice that the "32dip" is the amount of space from where the gradient ends to the end of the drawable, so that would leave me with a top and bottom gradients of "4dip" (36-32=4 :p)
Start with this:
Create a drawable:
<?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="#408DAA"/>
</shape>
</item>
<item >
<shape android:shape="rectangle">
<solid android:color="#50000000"/>
</shape>
</item>
<item android:top="10dip" android:bottom="10dip">
<shape android:shape="rectangle">
<solid android:color="#408DAA"/>
</shape>
</item>
</layer-list>
Use it as background of any view.
Adjust top, bottom and color="#408DAA" according your needs
I'd like to have a background color of a RelativeLayout similar to that of an image shown in the link below. Ignore the black strip in the bottom half of the image.
I don't want to use the image as a background of the layout. Can you give me an idea of how to proceed?
You can use gradient. Set different gradient in selector as you want. Done!
GradientDrawable.class
This is what you want, set your colors. Enjoy!
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:bottom="30dp">
<shape android:shape="rectangle" >
<corners
android:topRightRadius="8dip"
android:topLeftRadius="8dip" />
<gradient
android:startColor="#030303"
android:endColor="#3B3B3B"
android:angle="270" />
</shape>
</item>
<item android:top="30dp" >
<shape android:shape="rectangle" >
<corners
android:bottomLeftRadius="8dip"
android:bottomRightRadius="8dip" />
<gradient

android:endColor="#4B5059"

<size android:height="30dp" />
</shape>
</item>
</layer-list>
just try with shape file structure. I think this may give the solution.
//save this below code as gradient and use as background of your layout as
android:background="#drawable/gradient"
//gradient.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient android:startColor="#232323" android:endColor="#4B5059"
android:angle="270"/>
</shape>
