I assume your ListView has a ListAdapter (probably a BaseAdapter?). In your Adapter's getView(...) method, you have a position parameter. The position is the index into your array-list of data that you'd like to show in the correct list-item-view.
You get your data-item from the Adapter given the position (getItem(position)). You create your view, if your convertView is not yet set. In that view you have your EditText/TextViews and you assign the data from the data-item to these views. Use the method 'setTag(...)' of your list-item-view and set the data-item as the list-item-view's tag. When you convertView was null, you had to create you list-item-view. When creating this, set a TextWatcher to your EditText that allows you to be notified when the user changes the text. In your TextWatcher, get hold of the list-item-view of your EditText. Get the tag from the list-item-view (getTag(...) method) and that will be the data-item associated with that list-item-view. Update the changed text from the EditText in your data-item. When saving the data to the server, get hold of you Adapter, use getCount() and getItem(...) calls to get all the data-items. It should contain the updated EditText texts.
