title: Using setVisibility in Android?
body: <p>According to android docs,
  <code>void setVisibility(int visibility)</code> has One the following parameters <code>VISIBLE</code>, <code>INVISIBLE</code>, or <code>GONE</code>.</p>
  
  <pre><code>View dp2 = findViewByid(R.id.title);
  dp2.setVisibility(View.GONE);
  </code></pre>
  
  <p>So why do we have to use <code>View.GONE</code>, instead of <code>dp2.setVisibility(GONE);</code></p>
