title: Update ListView from adapter Instantly
body: <p>I'm developing an application that shows stock market information. In my application I use listactivity and my own adapter is being used. 
  The listView used to show the stocks is working fine and is updated with correct data. The only problem is, although I use </p>
  
  <pre><code> adapter.notifyDataSetChanged(); 
  </code></pre>
  
  <p>the list isn't updated until scrolling and items subjected to change, are scrolled out from the screen. When they are scrolled in, they appear with new data. 
  I need to change the data as soon as I notify the adapter.</p>
