title: ListView get slow when the Base adapter.getview() method is called
body: <p>I have been debugging my application and i saw that when i was scrolling the listview the method getView() of the class BaseAdapter is called to generate new views </p>
  
  <pre><code>public View getView(int position, View convertView, ViewGroup parent) {
      Article article = this.articles.get(position);
      return new MainView(this.context, articulo.getTitle() , articles.getDescription(),articles.getImgUrl());)  }
  </code></pre>
  
  <p>when i scroll the listActivity to see the new items  this method is invoked again to create the below list view items, as a consequence that the list items have images the ListActivity get slow, is there any way to create all the items view once, and not create ListItems when we are scrolling the listActivity</p>
