Android ListView get current position in visible items

Question

If the ListView 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 getSelectedItemPosition but it will return the position in all data. I want the position number in visible items shows on each item.

    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
        }
    }

Answer 1

getFirstVisiblePosition() can get first visible position in all items,so you can use getSelectedItemPosition()-getFirstVisiblePosition() to make it.

Answer 2

getFirstVisiblePosition() can get first visible position and getLastVisiblePosition() can get last visible position. So getLastVisiblePosition()-getFirstVisiblePosition() returns the number of visible item.
