Diamond shape xml background for android view

Hi anyone please suggest me how to create android xml drawable like below image?
Now I am using below code
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<rotate
android:fromDegrees="45"
android:pivotX="-40%"
android:pivotY="87%"
android:toDegrees="45">
<shape android:shape="rectangle">
<stroke
android:width="10dp"
android:color="#color/colorAccent" />
<solid android:color="#color/colorAccent" />
</shape>
</rotate>
</item>
</layer-list>
but its result is triangle but I need above shape.

Check this,
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:left="43dp"
android:top="43dp"
android:right="43dp"
android:bottom="43dp">
<rotate android:fromDegrees="45">
<shape>
<size
android:width="200dp"
android:height="200dp" />
<gradient
android:startColor="#0fdcc9"
android:endColor="#0fdcc9" />
<stroke
android:width="5dp"
android:color="#2DACA0" />
</shape>
</rotate>
</item>
</layer-list>

<?xml version="1.0" encoding="utf-8"?>
<vector xmlns:android="http://schemas.android.com/apk/res/android"

L188.706,51.8702 Z" />
</vector>
I include this in simple view:
<View
android:layout_width="100dp"
android:layout_height="40dp"
android:layout_centerInParent="true"
android:background="#drawable/ic_diamond"
/>
Here, is the result:

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:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

</layer-list>

layer-list not working as expected, I want to understand this concept

I have fair Idea about layer_list referred from here and here
here is my code
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:bottom="1dp"
android:left="1dp"
android:right="1dp"
android:top="1dp">
<shape android:shape="rectangle">
<solid android:color="#FEBB02" />
<corners android:radius="4dp" />
<size
android:width="40dp"
android:height="20dp" />
</shape>
</item>
<item
android:bottom="2dp"
android:left="10dp"
android:right="10dp"
>
<rotate
android:toDegrees="45"
android:fromDegrees="45"
android:pivotX="50%"
android:pivotY="50%">
<shape android:shape="rectangle">
<solid android:color="#3F51B5" />
<corners android:radius="2dp" />
</shape>
</rotate>
</item>
This is how it is look line in studio
but when I am applying background of Linearlayout it gives this result
I am expecting corner would be below the pointed as seen in studio.

I think you should try setting the clipToPadding and clipChildren attributes to false, inside the parent view of the linear layout.

Plz change size of Linearlayout to 150dp * 100dp.
