Hi all. I need some advice on how to best proceed. First, a little background. I have an application that uses a ListView as it's main activity to display all of the XML files from the /data/data/package.name/files directory. There may be hundreds of these files as the app gets used, so I pass the job of scanning the directory and loading the files into the ArrayAdapter using an AsyncTask that fires up a 'Loading...' ProgressDialog onPreExecute(), and closes it down onPostExecute(). In doInBackground(), I iterate through the files returned from a listFiles() call, storing the file names into the ArrayAdapter.
In terms of the AsyncTask, I've taken some direction here from Romain Guy's Shelves application in terms of the AsyncTask properly pausing/ storing, etc when it gets interrupted, and killed on Application termination. Everything here works OK, except that the ArrayAdapter can only tie in a single value (the filename in this case) to the View, and I's like to tie in multiple values/views pairs (in my case, filename, modified date). I've seen this done in the Notepad sample application, but that uses the SimpleCursorAdapter, but my understanding is that is exclusively tied to Cursors, and thus the SQLite database, which I don't need. So, here are my issues as I try to extend the very basic app: 1) How do I bind multiple values to multiple Views in the adapter. ArrayAdapter can't do it, is there another more appropriate option, or am I looking at creating my own custom adapter? If so, any example and/or suggestions on how to best proceed? 2) Am I going down the completely wrong path here with how I am tying files into the List... is there some 'hybrid' way to tie files to a Cursor such that I could use the SimpleCursorAdapter to handle all of this? 3) As a follow-up to that, in terms of adding items, I have an OptionsMenu that launches a Note Editing function (very similar to the Notepad example). I can create XML files via this method, but on going back to the ListView, the new items are not in the List, unsurprisingly. Notepad does this via the ContentResolver.insert() method, but with physical files scanned from the directory, I'm just not sure how I should be proceeding to update the List... I'd rather not have to re-scan every time a new note is added, but that may be my only option, as far as I know. Again, any help here is much appreciated. I see ArrayAdapter has insert/remove methods, but when in the child Editing activity, I'm not sure how I can access these (ContentResolver?). Thanks for any clarification here. 3) In terms of the Uri I define for each item, I am generating it from the absolute filepath, due to the fact that it may be possible in future versions to move/store files on the SD card, and I'm trying to maintain the Uniqueness of the Uri. Anyone see any issues with this solution? A very broad question, I hope the basic gist is clear... just trying to determine the best way to star so that I can move forward in the most efficient and correct way.
