title: Remove text padding in Button view
body: <p>I would like to remove the padding around text in Button view.
  The first screenshot is the result I would achieve, and the second one is the state of the art.</p>

  <p>Of course, I have defined a custom drawable to get the button appearance. But even if I set the padding attribute to 0dp the result does not change.</p>
  
  <p>Any suggestion, please?</p>
  
  <p><strong>EDIT</strong>
  Here is the xml code of the button</p>
  
  <pre><code>&lt;Button
          android:id="@+id/btnCancel"
          style="@style/dark_header_button"
          android:layout_width="wrap_content"
          android:layout_marginLeft="10dp"
          android:layout_height="wrap_content"
          android:includeFontPadding="false"
          android:padding="0dp"
          android:layout_alignParentLeft="true"
          android:layout_centerVertical="true"
          android:text="@android:string/cancel" /&gt;
  </code></pre>
  
  <p>Here is the style xml file:</p>
  
  <pre><code>&lt;style name="dark_header_button"&gt;
      &lt;item name="android:background"&gt;@drawable/bkg_dark_header_button&lt;/item&gt;
      &lt;item name="android:shadowDy"&gt;-1&lt;/item&gt;
      &lt;item name="android:shadowColor"&gt;#000000&lt;/item&gt;
      &lt;item name="android:shadowRadius"&gt;1&lt;/item&gt;
      &lt;item name="android:textSize"&gt;14sp&lt;/item&gt;
      &lt;item name="android:textColor"&gt;#ffffff&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>and here is the drawable xml file:</p>
  
  <pre><code>&lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
  
  &lt;item android:state_pressed="true"&gt;
      &lt;shape&gt;
  
          &lt;corners android:radius="10dp" /&gt;
  
          &lt;gradient 
              android:angle="90" 
              android:endColor="#060606"
              android:startColor="#707070"
              android:type="linear" /&gt;
  
      &lt;/shape&gt;
  &lt;/item&gt;
  &lt;item&gt;
      &lt;shape&gt;
  
          &lt;corners android:radius="10dp" /&gt;
  
          &lt;gradient 
              android:angle="90" 
              android:endColor="#707070" 
              android:startColor="#060606" 
              android:type="linear" /&gt;
  
          &lt;stroke 
              android:width="0.5dp" 
              android:color="#2b2b2b" /&gt;
  
      &lt;/shape&gt;
  &lt;/item&gt;
  
  
  &lt;/selector&gt;
  </code></pre>
