title: Radius in making border is given from inside instead of outside?
body: <p>I am using below XML for creating border for a <code>TextView</code>.</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; 
  
  &lt;layer-list xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;item&gt;
          &lt;shape android:shape="rectangle"&gt;
              &lt;solid android:color="@color/dark_gray" /&gt;
          &lt;/shape&gt;
      &lt;/item&gt;
      &lt;item android:bottom="1dp"&gt;
          &lt;shape android:shape="rectangle"&gt;
              &lt;solid android:color="@color/dark_gray" /&gt;
          &lt;/shape&gt;
      &lt;/item&gt;
      &lt;item
          android:bottom="2dp"
          android:top="2dp"&gt;
          &lt;shape android:shape="rectangle"&gt;
              &lt;solid android:color="@color/dark_gray" /&gt;
          &lt;/shape&gt;
      &lt;/item&gt;
      &lt;item
          android:bottom="2dp"
          android:left="2dp"
          android:right="2dp"
          android:top="2dp"&gt;
          &lt;shape android:shape="rectangle"&gt;
              &lt;solid android:color="@color/white" /&gt;
              &lt;corners android:radius="@dimen/padding_4dp"/&gt;
          &lt;/shape&gt;
      &lt;/item&gt;
  &lt;/layer-list&gt;
  </code></pre>
  
  <p>When I give radius as <code>&lt;corners android:radius="@dimen/padding_4dp"/&gt;</code>, it gives radius to corners but from inside, not from outside. So, as a result, corners remain sharp from outside. Like below:

  <p>Am I doing wrong somewhere?</p>
