title: Android refresh screen aftet button clicked
body: <p>I have an <code>Activity</code>. It's <code>Layout</code> has 2 <code>Buttons</code>. When I click the first <code>Button</code> a <code>Dialog</code> opens . <code>Dialog</code> contains a <code>ListView</code>. When I close the <code>Dialog</code> I want to do refresh on <code>Activity</code>. So the text of the first <code>Button</code> will be different. </p>
  
  <pre><code>sportSuvis.setText("Sports "); 
  sportSuvis.setOnClickListener(new View.OnClickListener() {
        @Override 
        public void onClick(View v) { 
          SportListViewDiaolog myDialog = new SportListViewDiaolog(v.getContext(),"",null); 
         myDialog.show(); 
         } 
  }); 
  </code></pre>
  
  <p>after dialog dismiss I want to do refresh</p>
  
  <p>Thanks</p>
