title: inflate vs findViewById
body: <p>Suppose I have a simple layout xml like the following:</p>
  
  <p>button.xml:</p>
  
  <pre><code>&lt;Button
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/button01"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content" /&gt;
  </code></pre>
  
  <p>Are there any differences in the following calls? and which one should i use?</p>
  
  <pre><code>button = (Button) getLayoutInflater().inflate(R.layout.button, null);
  </code></pre>
  
  <p>and</p>
  
  <pre><code>View v = getLayoutInflater().inflate(R.layout.button, null);
  button = (Button) v.findViewById(R.id.button01);
  </code></pre>
