Why i am not able to create the round border for specific corner?

I am also facing the same problem. But for that I use layer-list. I post my answer here which may help you.
Please check output screen

<?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="#c1c1c1" />            <solid android:color="#c1c1c1" />            <corners android:radius="20dp"/>        </shape>   </item>   <item android:right="20dp"        >      <shape         android:shape="rectangle">            <stroke android:width="1dp" android:color="#c1c1c1" />            <solid android:color="#c1c1c1" />        </shape>   </item></layer-list>

You'll have to do that, assuming you only want a rounded top left corner:

<shape xmlns:android="http://schemas.android.com/apk/res/android"       android:shape="rectangle">  <corners      android:radius="20sp"      android:topRightRadius="0dp"      android:bottomRightRadius="0dp"      android:bottomLeftRadius="0dp" />  <gradient      android:startColor="@color/logo_blue"      android:endColor="@color/blue"      android:angle="0"/></shape>

Explanation: Every corner must (initially) be provided a corner radius greater than 1, or else no corners are rounded. If you want specific corners to not be rounded, a work-around is to use android:radius to set a default corner radius greater than 1, but then override each and every corner with the values you really want, providing zero ("0dp") where you don't want rounded corners. ^[source]

As a consequence, you need to define your drawable as:

<?xml version="1.0" encoding="UTF-8"?><shape     xmlns:android="http://schemas.android.com/apk/res/android">    <stroke         android:width="1dip"         android:color="#ffffff"/>    <solid         android:color="#95865F"/>    <corners        android:radius="10px"      android:topRightRadius="0dp"      android:bottomRightRadius="0dp" />    <padding         android:left="1dp"        android:right="1dp"        android:top="1dp"        android:bottom="1dp"/> </shape>

Update

From The Shape Drawable Resource Android Documentation:

android:radius Dimension. The radius for all corners, as a dimension value or dimension resource. This is overridden for each corner by the following attributes.

overridden is the keyword for your problem…

I'm using SDK tools 19, platform-tools 11 and running the app in Android 4.0.3. Using the following XML works for me:

<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android"     android:shape="rectangle">    <solid android:color="#dd000000"/>    <padding         android:left="7dp"        android:top="7dp"        android:right="7dp"        android:bottom="7dp" />    <corners        android:bottomLeftRadius="25dp"        android:bottomRightRadius="25dp"        android:topLeftRadius="0dp"        android:topRightRadius="0dp" /></shape>

The Eclipse warning is about not being able to show the preview. In het app it shows up correct.
