what is the right way to update List view inside widget after changes made in config file

Question

i would like to know how to refresh listview inside widget .

on my config file i use

Intent intent = new Intent();
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
setResult(Activity.RESULT_OK, intent);

after you edit the config file .

maybe i can refresh the all widget somehow ?

i guess what i am asking is :

note that if i remove the widget and add it again it shows the widget with the new config .

thanks for advance for explaining this issue .

You can get the instance of the adapter of the listview and call the notifyDataSetChanged() of the adapter instance.
