title: How to set the application to fullscreen from an Intent, Not from the main activity
body: <p>My Application Has 4 Tabs, Each tab creates a subview ( intent ) now I have a handler for options/menu button within each intent , of the menu items is "Toggle Fullscreen" this doesn't work as the intent isn't the parent view while the activity containing the TabHost is the parent View, Now I need to know how do I Set the whole app. to FullScreen mode or how to Refer to the Parent Activity to Set the full screen mode through it.</p>
  
  <p>Here's a snippet of my code </p>
  
  <pre><code>    public class MainActivity extends TabActivity {
  
      public void toggleFullScreen(){
      // This has the code to set App. to full screen
      }
  
      public void onCreate(Bundle savedInstanceState) {
  
          super.onCreate(savedInstanceState);
          Intent myIntent = new Intent(this, MywebviewActivity.class);
          tabHost.addTab(             
                  tabHost.newTabSpec("SomeName")
                  .setIndicator("Some Title")
                  .setContent( myIntents ));
  </code></pre>
  
  <p>Now I need to set fullscreen mode from "MywebviewActivity" not from my MainActivity</p>
