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

Question

In My android xml layout i am applying the border by using the borderframe.xml as a background.

borderframe.xml file is looks like below:

Answer 1

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.

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>

I got the solution on one of the forums. I solved it by commenting each corner & adding to the xml in drawable. I have retained commented code below only for understanding.

XML Code-

   <?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
        <solid android:color="#fd2149" />
        <stroke android:width="1dip" android:color="#ffd102"/>
      <!--  <corners
            android:bottomLeftRadius="8dp"
            android:bottomRightRadius="8dp"
            android:topLeftRadius="8dp"
            android:topRightRadius="8dp" />
        -->
        <corners android:radius="8dp" />
    </shape>

---Edited- The above code is my back.xml in drawable folder and if required you can add padding to the same back.xml. For those who are new developers, the back.xml is referenced from your layout file as follows

  <TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tableLayout1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:textSize="20sp"
    android:scrollbars="vertical"
    android:background="@drawable/back">

Hope this helps.

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…
