android:height="1dp"
android:gravity="center">
<shape android:shape="rectangle">
<solid android:color="#ff0000" />
</shape>
</item>
<item
android:width="56dp"
android:height="56dp"
android:gravity="center">
<shape android:shape="oval">
<solid android:color="#ff0000" />
</shape>

android:layout_height="wrap_content"
android:layout_below="#+id/txtstep"
android:layout_marginLeft="30dp"
android:layout_marginRight="30dp"
android:layout_marginTop="6dp">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:background="#drawable/simple_border_white"
android:textSize="3dp" />
<TextView

hope this helps

Create your drawable file and put below code.
And change your color code red.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:bottom="10dp"
android:left="10dp"
android:right="10dp"
android:top="10dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#color/colorAccent" />
<size
android:width="10dp"
android:height="10dp" />
</shape>
</item>
<item>
<rotate
android:fromDegrees="180"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="90">
<shape
android:shape="line"
android:top="1dp">
<stroke
android:width="0.5dp"
android:color="#color/colorAccent" />
</shape>
</rotate>
</item>

Use below drawable XML into your views background :
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:width="100dp"
android:height="100dp"
android:gravity="center">
<shape android:shape="oval">
<solid android:color="#android:color/holo_red_dark" />
<!--background color of box-->
</shape>
</item>
<item
android:height="10dp"
android:gravity="center">
<shape android:shape="rectangle">
<solid android:color="#android:color/holo_red_dark" />
<!--background color of box-->
</shape>
</item>
</layer-list>

Attributes height and width in <item/> are supported since 23 api.
For earlier versions you can use following code:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:gravity="center">
<shape android:shape="rectangle">
<size android:height="1dp" />
<solid android:color="#ff0000" />
</shape>
</item>
<item android:gravity="center">
<shape android:shape="oval">
<size
android:width="30dp"
android:height="30dp" />
<solid android:color="#ff0000" />
</shape>
</item>

How to draw vertical shape in the centre of XML drawable

How can a vertical line be drawn within an XML drawable when using a layer-list? I declared 3 shapes within the drawable but for some reason it doesn't appear as expected.
<?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/green"/>
</shape>
</item>
<item android:top="0dp" android:left="1dp" android:bottom="0dp" android:right="5dp">
<shape android:shape="rectangle">
<size android:width="3dp"/>
<solid android:color="#android:color/white"/>
</shape>
</item>
<item android:top="0dp" android:left="5dp" android:bottom="0dp" android:right="1dp">
<shape android:shape="rectangle">
<size android:width="3dp"/>
<solid android:color="#android:color/white"/>
</shape>
</item>
</layer-list>
Current result
Expected result

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:width="16dp"
android:left="15px">
<shape
android:shape="rectangle">
<solid android:color="#color/colorAccent" />/>
<size android:width="5dip" />
<stroke android:color="#color/colorAccent" />
</shape>
</item>
<item
android:width="16dp"
android:left="80px">
<shape
android:shape="rectangle">
<solid android:color="#color/colorAccent" />/>
<size android:width="5dip" />
<stroke android:color="#color/colorAccent" />
</shape>
</item>
<item
android:width="16dp"
android:left="140px">
<shape
android:shape="rectangle">
<solid android:color="#color/colorAccent" />/>
<size android:width="5dip" />
<stroke android:color="#color/colorAccent" />
</shape>
</item>
</layer-list>

Try this solution
drawable/shape.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#color/colorAccent" />/>
<size android:width="5dip" />
<stroke
android:color="#color/colorAccent"
/>
</shape>
Include in the layout file the following
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<View
android:layout_width="15dip"
android:layout_height="wrap_content"
android:layout_margin="#dimen/activity_horizontal_margin"
android:background="#drawable/shape"></View>
<View
android:layout_width="15dip"
android:layout_height="wrap_content"
android:layout_margin="#dimen/activity_horizontal_margin"
android:background="#drawable/shape"></View>
<View
android:layout_width="15dip"
android:layout_height="wrap_content"
android:layout_margin="#dimen/activity_horizontal_margin"
android:background="#drawable/shape"></View>
</LinearLayout>
Change the colors and fix the margins of the layout.

Custom shape in android using xml

I am trying to draw a custom shape which I can use as a background for my layout. But I am not able to do so. Is it possible to draw a shape as below using xml in android. I am not getting how to cut the semicircle shape from the vertical centres of rectangle.

Use layer-list to make this custom shape drawable.
/res/drawable/custom_shape.xml:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Transparent Rectangle -->
<item>
<shape android:shape="rectangle">
<corners
android:topLeftRadius="8dp"
android:topRightRadius="8dp"
android:bottomLeftRadius="4dp"
android:bottomRightRadius="4dp" />
<size
android:width="300dp"
android:height="100dp" />
<solid android:color="#FFFFFF" />
</shape>
</item>
<!-- Left Half-Circle -->
<item
android:left="-10dp"
android:right="290dp"
android:top="40dp"
android:bottom="40dp">
<shape android:shape="oval">
<solid android:color="#000000" />
</shape>
</item>
<!-- Right Half-Circle -->
<item
android:left="290dp"
android:right="-10dp"
android:top="40dp"
android:bottom="40dp">
<shape android:shape="oval">
<solid android:color="#000000" />
</shape>

<shape android:shape="line">
<stroke
android:width="1dp"
android:dashWidth="10px"
android:dashGap="10px"
android:color="#ff00"/>
</shape>
</item>
</layer-list>
USE:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/custom_shape"/>

Hope this will help~

In your case it might be worth to create a resizable bitmap (9-Patch drawable). Follow this guide.

try bellow xml. save it in drawable.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<corners
android:topLeftRadius="15dp"
android:topRightRadius="15dp"
android:bottomLeftRadius="5dp"
android:bottomRightRadius="5dp"
/>
<solid
android:color="#ffffff"
/>
<padding
android:left="0dp"
android:top="0dp"
android:right="0dp"
android:bottom="0dp"
/>
<stroke
android:width="1dp"
android:color="#000000"
/>
</shape>

It is better to use 9-Patch images. If you can create an image like above you can use https://romannurik.github.io/AndroidAssetStudio/nine-patches.html to create 9-patch image(define expandable area).

Try this xml file in drawable :
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape= "rectangle">
<solid android:color="#color/primary" />
<corners android:radius="50dp"/>
</shape>

Please refer the below xml, it may help you out
<?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="#android:color/black" />
</shape>
</item>
<item
android:bottom="10dp"
android:left="10dp"
android:right="10dp"
android:top="10dp">
<shape android:shape="rectangle">
<size
android:width="200dp"
android:height="200dp" />
<solid android:color="#color/colorAccent" />
<corners android:radius="5dp" />
</shape>
</item>
<item>
<shape android:shape="line">
<solid android:color="#android:color/black" />
<stroke android:width="1dp"
android:dashWidth="10px"
android:dashGap="10px"/>
</shape>
</item>
<item
android:bottom="103dp"
android:left="-10dp"
android:right="205dp"
android:top="103dp">
<shape android:shape="oval">
<size
android:width="3dp"
android:height="3dp" />
<solid android:color="#android:color/black" />
<stroke android:width="1dp" />
</shape>
</item>
<item
android:bottom="103dp"
android:left="205dp"
android:right="-10dp"
android:top="103dp">
<shape android:shape="oval">
<size
android:width="3dp"
android:height="3dp" />
<solid android:color="#android:color/black" />
<stroke android:width="1dp" />
</shape>
</item>
</layer-list>

Try below code
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#FFFFFF" />
<corners android:radius="3dip" />
<stroke
android:width="1dp"
android:color="#ED2A3C" />
</shape>

Android banner ribbon using shape

I am trying to figure out how I would stack shapes so I can create the following ribbon(Pink/White/Pink/White/Pink part). I will then be using this as a background for my textview.

I figured it out using a layer-list
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#FFe5887c" />
<size android:width="2dp" android:height="2dp"/>
</shape>
</item>
<item android:top="2dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#FFFFFFFF" />
<size android:width="1dp" android:height="1dp"/>
</shape>
</item>
<item android:top="3dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#FFe5887c" />
<size android:width="20dp" android:height="20dp"/>
</shape>
</item>
<item android:top="23dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#FFFFFFFF" />
<size android:width="1dp" android:height="1dp"/>
</shape>
</item>
<item android:top="24dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#FFe5887c" />
<size android:width="2dp" android:height="2dp"/>
</shape>
</item>
</layer-list>
