title: Android ListView get current position in visible items
body: <p>If the <code>ListView</code> only shows 5 items, and the all data is 40 items. How can I get the current selection is which position in visible items (1~5)? I have tried  <code>getSelectedItemPosition</code> but it will return the position in all data. I want the position number in visible items shows on each item.</p>
  
  <pre><code>    class MyAdapter extends BaseAdapter {
          @Override 
          public int getCount(){
           ...
          }
          @Override 
          public Object getItem(int position){
           ...
          }
          @Override    
          public View getView(int position, View convertView, ViewGroup parent)
          {  
             // I want to get the position number in visible items here
          }
      }
  </code></pre>
