Implement your subclass of BaseAdapter (e.g. JSONArrayAdapter).
Implement/override the getCount(), getItem(int position), etc. to make
your BaseAdapter a proper list-adapter around your jsonarray.
Implement the getView method; it provides the 'position' and
'contentView' parameters.
- Use position and getItem(position) to obtain an json-element from
your jsonarray.
- re-use contentView or create a brand-new one if it is null:
- Assign text/images to the contentView (or its child-view) based
on
the json-element you got.
Then assign an instance of your JSONArrayAdapter to your list- or grid-
view.
And viola. It should work :)
Take a look at the 'API Demo' in the Android SDK for examples.
