Ideally an adapter is an object to adapt a particular dataset to render a view within a listview. So you should have a data structure (class object) for every row visible in that list view and put it in an array list. Based on the position in getView method, retrieve the data for the row and initialize views from this data. Now this data set can be saved on server or in local memory in any format preferably in JSON and can be retrieved back in future.
