Output like

It can be done using ConstraintLayout.
Alight your profile pic in vertical center of top border of your rectangle and apply some start(left) margin to it.

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>

Create xml Chat Bubble With the Shape As in the .png File

Could I please ask if anyone knows how to create an xml shape of the chat bubble below? The only examples I found online were two separate shapes that were put as two separate backgrounds in a layout - a triangle and a rectangle. I tried combining the triangle and rectangle to no avail. The triangle seems to hide in the rectangle.
Setting a top attribute to the triangle to move it down makes the ImageView object blank.
Please see what I tried:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<!--rectangle with rounded corners-->
<item android:top="0dp" android:bottom="20dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#android:color/black" />
<size
android:width="106dp"
android:height="20dp"/>
<stroke
android:width="1dp"
android:color="#000" />
<corners android:radius="8dp" />
</shape>
</item>
<!--triangle-->
<item android:bottom="0dp" android:top="20dp" android:gravity="center_horizontal|bottom">
<rotate
android:fromDegrees="45"
android:toDegrees="45"
android:pivotX="135%"
android:pivotY="15%">
<shape android:shape="rectangle">
<solid android:color="#android:color/black" />
<size
android:height="10dp"
android:width="10dp"/>
</shape>
</rotate>
</item>
</layer-list>
This is the usage in the imageView:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="net.eventilate.shapes.Balloon">
<ImageView
android:layout_width="106dp"
android:layout_height="30dp"
android:id="#+id/imageView2"
android:contentDescription="#string/test"
android:background="#drawable/balloon"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>

You can Use this code
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:top="0dp" android:bottom="10dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#android:color/holo_blue_light" />
<size
android:width="106dp"
android:height="20dp"/>
<stroke
android:width="1dp"
android:color="#40adc2" />
<corners android:radius="4dp" />
</shape>
</item>
<item android:bottom="0dp"
android:top="0dp"
android:gravity="center_horizontal|bottom">
<rotate
android:fromDegrees="45"
android:toDegrees="45"
android:pivotX="135%"
android:pivotY="15%">
<shape android:shape="rectangle">
<solid android:color="#android:color/holo_blue_light" />
<size
android:height="10dp"
android:width="10dp"/>
</shape>
</rotate>
</item>
</layer-list>
it get this result:

This is exactly what you need:

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">

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"

</layer-list>
USE:
<LinearLayout

android:layout_height="wrap_content"
android:background="#drawable/custom_shape"/>
OUTPUT:
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="#color/colorAccent" />
<corners android:radius="5dp" />
</shape>
</item>
<item>

android:height="3dp" />
<solid android:color="#android:color/black" />
<stroke android:width="1dp" />
</shape>
</item>
</layer-list>

Try below code
