    2. COafter that of course, call the notifyDatasetChanged() from the Adapter...make sure that the list is only changed or accessed from the UIThread( getView() is on the UIThead) and the onPostExecute() from the AsyncTask is also on the UIThread..so you can make a call to set the new populated list from there...if you do it from another thread, you will have to deal with multithreaded conditions having to synchronized your code properly..so use this as suggested that you will have no problems. Make the prototype, evaluate and adapt any improvements you find. Best of luck!

    3. COit's simple...basically the core of the idea is to build the UI completely independent of the logic or origin of the data...so to start with: define the model (ValueObjects) a simple object with getters and setters...then on your adapter you make a variable with a list of them...and ensure that the getItem fetches the object from this list, and the getView builds the view based on the object retrieved from this list...now, just build something that changes this list whenever needed, you can use a AsyncTask that fetches the data from the server, populate these objects and set them to this list.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
