title: The method getApplicationContext() is undefined - fragment issues
body: <p>I am getting the following errors:
  The method getApplicationContext() is undefined 
  The method findViewById(int) is undefined for the type Fragment1</p>
  
  <p>These errors seem to be eliminated when my class is extended to an Activity as oppose to a fragment, but it is important that this activity remains as a fragment, so I am not too sure how to work this out.</p>
  
  <p>Any help would be greatly appreciated.
  Thanks in advance.</p>
  
  <p>Below is the code</p>
  
  <pre><code>public class Fragment1 extends Fragment {
