Dotted dash vertical line with gradient color

I want to make dotted line vertically with the gradient color effect. But I'm unable to do that. How can I approach. I am using this code on drawable for the dotted line
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:left="3px"
android:right="-5px"
android:top="-5px"
android:bottom="-5px">
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="4px"
android:color="#color/colorPrimary"
android:dashGap="20px"
android:dashWidth="20px" />
</shape>
</item>
</layer-list>
Anyone knows please help
Thanks in advance

create a drawable like below
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:bottom="-5px"
android:left="3px"
android:right="-5px"
android:top="-5px">
<shape>
<gradient
android:angle="270"
android:centerColor="#00ff00"
android:endColor="#ff0000"
android:startColor="#0000ff"/>
<stroke
android:width="2dp"
android:color="#fff"
android:dashWidth="8dp"
android:dashGap="16dp"/>
</shape>
</item>
</layer-list>
now in layout you need to use a view and set this shape as background to it.
<View
android:layout_width="4dp"
android:layout_height="match_parent"
android:background="#drawable/your_shape"/>
you might need to change widht settings as per your requirements. Here is what I got

You can use shape Try this...
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line">
<stroke
android:color="#000000"
android:dashWidth="10px"
android:dashGap="10px"
android:width="1dp"/>
</shape>

Create shape for drawable

I have ListView, and i have a background for the list items:
Is there any way to recreate this background as a shape in drawable XML? The most outer grey is not part of the item background, it is actually the ListView.

You can try following with the values of your choice. It will make the bottom two corners rounded.
rounded_rectangle.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<gradient android:angle="270" android:endColor="#404040" android:startColor="#404040" />
<stroke android:width="1dp" android:color="#808080" />
<corners android:bottomLeftRadius="11dp" android:bottomRightRadius="11dp"/>
</shape>
</item>
</selector>
then use it as a background to your listitem as follows
android:background="#drawable/rounded_rectangle"

You can try this shape drawable:
<?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>

Layout with different colors

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:startColor="#4B5057"
android:endColor="#4B5059"
android:angle="270" />
<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>

how to make stroke for 3 sides for a shape in android?

I am using a stroke to make a colored border to a shape in xml layout in android .
Can I make the stroke for only 3 edges ( left,top,bottom) the right NO ?

You can achieve this by using a layerlist and messing with the padding. You'll need 3 elements:
1: A border.xml shape, which is just a solid shape in the color of your border: border.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#ff0000"/>
</shape>
2: The 'inner' shape, the shape where you want the border to appear around: inner.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#00ff00"/>
</shape>
3: A layer list, which will put these 2 on top of eachother. You create the border by setting the padding on the inner shape: layerlist.xml
<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/border"/>
<item android:drawable="#drawable/inner"
android:top="3dp" android:right="0dp" android:bottom="3dp"
android:left="3dp" />
</layer-list>

Using #Mopper answer, you can like that too.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<solid android:color="#ff0000" />
</shape>
</item>
<item
android:bottom="3dp"
android:left="3dp"
android:right="0dp"
android:top="3dp">
<shape>
<solid android:color="#00ff00" />
</shape>
</item>
</layer-list>

Here's my solution, which works if you want transparent or semi-transparent background colors.
<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetLeft="-1dp"
>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke
android:color="#c45b5b5b"
android:width="1dp"/>
<corners
android:bottomLeftRadius="0dp"
android:bottomRightRadius="5dp"
android:topLeftRadius="0dp"
android:topRightRadius="5dp"
/>
</shape>
</inset>
</item>
<item
android:top="1dp"
android:right="1dp"
android:bottom="1dp"
android:left="0dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#color/infoBox_Background"/>
<corners
android:bottomLeftRadius="0dp"
android:bottomRightRadius="5dp"
android:topLeftRadius="0dp"
android:topRightRadius="5dp"
/>
</shape>
</item>
</layer-list>

Another approach would be to use a 9-Patch png file for your background. You do this by taking a normal png file and then using a tool like this to define:
The area where your content goes in the png.
The area of your png that stretches as the underlying control grows in either width or height.
Once you generate the 9-patch png file, add it to your drawables (define files for various resolutions). Then just set the drawable as your control background.
android:background="#drawable/my9_patch_file_name"

Square shaped layout border with round inside edges

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

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

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

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

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