Custom CursorLoader notify data change

问题

I was looking at the answer for making a Custom CursorLoader, and was wondering that if the data changes would there will be a notification of the data changing so that the list updates?

回答1:

I'm using the compatibility library loader framework. When content changes I just call this and everything gets updated:

    getSupportLoaderManager().getLoader(YOUR_LOADER).onContentChanged();

回答2:

You could call notifyDataSetChanged on your adapter so that the ListView will display the updated cursor content.

From the documentation:

Notifies the attached observers that the underlying data has been changed and any View reflecting the data set should refresh itself.
