title: variable width button layout
body: <p>I'm currently trying to make a button with a border around it. This border however needs a different width on different sides, for example 10px on left and rigt and 5px on top and bottom.
  I've managed to create a rectangle with a 10px border using shape. Code is below. My question is how can I decrease the border width on arbitrary sides?</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;gradient android:startColor="#FFFFFF"
                  android:endColor="#7A7A7A"
                 android:angle="270" /&gt;
  
              &lt;corners android:radius="3dp" /&gt;
             &lt;stroke android:width="10px" android:color="#000000" /&gt;
          &lt;/shape&gt;
      &lt;/item&gt;
  &lt;/layer-list&gt;
  </code></pre>
