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:color="#de0b0b" />
<solid android:color="#ffffff" />
<corners android:radius="20dp" />
</shape>
</item>
<item
android:bottom="5dp"
android:top="0dp">
<shape android:shape="rectangle">
<stroke
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"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"

android:background="#drawable/test"
android:text="Nilesh"
android:gravity="center"
android:layout_margin="#dimen/_5sdp"
android:padding="#dimen/_5sdp">
</TextView>
</LinearLayout>

Try this
<?xml version="1.0" encoding="utf-8"?>

I have this image of the seekbar that I want to build:
But my seekbar is looking like this:
My seekbar has no transparency and I can not make it thinner.
How can I do this?
Here are the codes:
Seekbar:

------- I am using them like
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="wrap_content"
android:layout_height="wrap_content" >

android:paddingBottom="5dp"
android:paddingTop="5dp"
android:background="#drawable/right_bubble_chat_drawable">
</RelativeLayout>
</RelativeLayout>
Please suggest me how can I add shadow effect below the bubble as in the image below

You can try by implementing a layer-list that will act as the background for the LinearLayout and add your view inside this.
Quote from an answer to this question:
Add background_with_shadow.xml file to res/drawable. Containing:
<?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/darker_gray" />
<corners android:radius="5dp"/>
</shape>
</item>
<item android:right="1dp" android:left="1dp" android:bottom="2dp">
<shape
android:shape="rectangle">
<solid android:color="#android:color/white"/>
<corners android:radius="5dp"/>
</shape>
</item>
</layer-list>
Then add the the layer-list as background in your LinearLayout.
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/background_with_shadow"/>
EDIT
You can create seprate xml for creating gray image like thsis:
----right_bubble_shdw_chat_drawable
<?xml version="1.0" encoding="utf-8"?>
<shape android:shape="rectangle" xmlns:android="http://schemas.android.com/apk/res/android">

<padding
android:bottom="10dp"
android:left="10dp"
android:right="10dp"
android:top="10dp" />
<size
android:height="#dimen/normal_button_height"
android:width="#dimen/normal_button_width" />
--- for corner pointer 'chat_laftarraow_shdw'
<?xml version="1.0" encoding="utf-8"?>

<rotate

creating a drawable file to make a separator

I'm using the following code to display a separator view in my activity:
<View
android:id="#+id/view"
android:layout_width="2dp"
android:layout_height="wrap_content"
android:layout_marginRight="15dp"
android:layout_toLeftOf="#id/signoutbutton"
android:background="#drawable/separator" />
My separator.xml file is as follows:
<?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:height="54dp"
android:width="1dp"
android:color="#FFFFFF" />
<solid android:color="#FFFFFF" />
</shape>
</item>
<item>
<shape android:shape="rectangle" >
<stroke
android:height="54dp"
android:width="1dp"
android:color="#color/blue" />
<solid android:color="#color/blue" />
</shape>
</item>
</layer-list>
however, I am achieving this
The problem is that only the blue color is shown and not the white as I had stated in the drawable file. How can I correct this?

you should try to use as below:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle" >
<gradient
android:endColor="#FFFFFF"
android:startColor="#color/blue"
android:angle="90" />
</shape>
</item>
</layer-list>

Hope this help you
