BaseAdapter?

[Alexsun]

I dont understand the BaseAdapter very well.
There are some fuctions needed to override.

public int getCount()
public Object getItem(int position)
public long getItemId(int position)
public View getView(int position, View convertView,
ViewGroup parent)

how the system works?
Especially, how the system knows the parameter of position, cuz i never mannually pass this parameter to these functions.

Somebody can explain it?

Thanks very much.
