Refresh ListView if I changed the contents of ListItem

Question

I have a ListView in my Android activity. And I populate the ListView with a subclass of BaseAdaptor (which returns the View method in getView ()).

What should I do if in my click listener there are buttons in the list item view I

• change the text of the textview in the list view or
• resize the view of the list item by adding / removing children of the list of list items.

What is effective for updating my list? I do not want listView to re-run the request because there are no data changes.

Thank.

Answer 1

If you just change the contents of your child view, you do not need to do more than that TextView.setText(newText).

ListView, BaseAdaptor.notifyDataSetChanged()
