Android Drawable Horizontal Line

Is it possible to make line to be like this with xml? or there's some way to do that..?
I already made some drawable with shape but it's not really like i want
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners
android:bottomLeftRadius="30dp"
android:bottomRightRadius="30dp"
android:topLeftRadius="0dp"
android:topRightRadius="0dp" />
<padding
android:bottom="0dp"
android:left="0dp"
android:right="0dp"
android:top="0dp" />
<stroke
android:width="0.8dp"
android:color="#color/colorPrimaryDark" />
<solid android:color="#android:color/transparent" />
</shape>

We can create a drawable file also for this. May be helpful for someone.
Drawable file:
<?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/white" />
</shape>
</item>
<item>
<shape android:shape="rectangle">
<stroke
android:width="5dp"
android:color="#android:color/holo_blue_dark" />
<solid android:color="#android:color/white" />
<corners android:radius="20dp" />
</shape>
</item>
<item android:bottom="25dp">
<shape android:shape="rectangle">
<stroke
android:width="2dp"
android:color="#android:color/white" />
<solid android:color="#android:color/white" />
</shape>
</item>
</layer-list>
Result :

<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetLeft="-5dp"
android:insetRight="-5dp"
android:insetTop="-10dp">
<shape android:shape="rectangle">
<solid android:color="#android:color/transparent" />
<stroke
android:width="3dp"
android:color="#color/colorPrimaryDark" />
<corners
android:bottomLeftRadius="25dp"
android:bottomRightRadius="25dp" />
</shape>
</inset>

Try this
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<stroke
android:width="1dp"

android:width="10dp"
android:color="#ffffff" />
<solid android:color="#android:color/transparent" />
<corners android:radius="20dp" />
</shape>
</item>
</layer-list>
USE like this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

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.

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:
