title: How to force an entire layout View refresh?
body: <p>I want to force the main layout resource view to redraw / refresh, in say the Activity.onResume() method. How can I do this ? </p>
  
  <p>By main layout view, I mean the one ('R.layout.mainscreen' below) that is called in my Activity.onCreate(), like this:-</p>
  
  <pre><code>protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.mainscreen);
  }
  </code></pre>
