问题 I was wondering, is there any guideline, on how we choose between ArrayAdapter and SimpleAdapter . For every list item, they will be presented by several TextViews and Views, which is being layout nicely. I realize I can implement both without any problem, by either using ArrayAdapter or SimpleAdapter . Is there any guideline, on how we choose among them?
