title: Android - button background color shrinks the height of the button
body: <p>I have this button</p>
  
  <pre><code>&lt;Button
  android:id="@+id/learn"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:layout_marginTop ="5dp"
  android:text="Hello StackOverflow"
  style="@style/home_page_buttons"    
  /&gt;   
  </code></pre>
  
  <p>and I am trying to give it this style</p>
  
  <pre><code>&lt;style name="home_page_buttons"&gt;  
      &lt;item name="android:layout_marginLeft"&gt;15dp&lt;/item&gt;
      &lt;item name="android:layout_marginRight"&gt;15dp&lt;/item&gt;
  
      &lt;item name="android:textColor"&gt;@color/light_best_blue&lt;/item&gt; 
      &lt;item name="android:textStyle"&gt;bold&lt;/item&gt;   
      &lt;item name="android:color"&gt;@color/white&lt;/item&gt;  
       &lt;item name="android:background"&gt;@color/white&lt;/item&gt;
  
  &lt;/style&gt;
  </code></pre>
  
  <p>This line:</p>
  
  <pre><code> &lt;item name="android:background"&gt;@color/white&lt;/item&gt;
  </code></pre>
  
  <p>makes the backgrond white as I wanted, but for some reason, it shrinks down the height of the button and makes it ugly.</p>
  
  <p>Any idea why that happens and how to stop this side effect?</p>
  
  <p>Thanks!    </p>
