title: Android - Button height not decreasing to wrap text
body: <p>I set the button's height via XML. Suppose it to be X</p>
  
  <pre><code>&lt;Button
      android:layout_height="wrap_contnet"
      android:textSize = " &lt;X&gt; dp"
      ....
      ....
  /&gt;
  </code></pre>
  
  <p>If I set X to greater than 15 dp, the button's height grows to fit the text. But when I set it to something lower like 2dp, the button's height doesn't change and I can see a thick border around it as shown below:-</p>

  <p>As shown above, text size is so small but still height doesn't decrease!
  How can I force it to be of appropriate height?</p>
  
  <p>Thanx in advance!</p>
