title: Android : How do I update my textView in a Fragment
body: <p>I am trying to use fragments to build my first proper Android App.
  I have a main xml. which consists of two vertical fragments, the top fragments consists of just two TextViews.  The first of these contains static text and the second contains a value which I will eventually be getting dynamically from SQL.</p>
  
  <p>If i put this is my MainActivity.java then it happily updates the value of the TextView in my first Fragment:</p>
  
  <pre><code>public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
  
      setContentView(R.layout.activity_main);
  
      // Set the Text to try this out
      TextView t = (TextView)findViewById(R.id.viewItem);
      t.setText("Text to Display");
  }
  </code></pre>
  
  <p>I have two fragment XMLs and a java to support each so I want to put the setting of this field into the Java that supports the fragment rather than the java that is for the MainActivity.</p>
  
  <p>When I put it in the fragment it looks like this:-</p>
  
  <pre><code>    public class FragmentMainTop extends Fragment {
  @Override
  public View onCreateView(LayoutInflater inflater,
          ViewGroup container, Bundle savedInstanceState){
      // -- inflate the layout for this fragment
      return inflater.inflate(R.layout.fragmentmt, container,false);
  
      // Set the Text to try this out
      TextView t = (TextView)findViewById(R.id.viewItem);
      t.setText("Text to Display");
  }
  </code></pre>
  
  <p>But if I do this I get an error on the TextView line:</p>
  
  <p>"The method findViewById(int) is undefined for the type FragmentMainTop"</p>
  
  <p>So why does it not know this method?  I have ctl/shift/o so I know I have all the right imports.
  I don't want to end up putting all my code in the MainActivity because if I want to then use the Fragment in another activity I will have to repeat all the code.</p>
