Hi there,
Here is the situation. In a TabbedView, one of three tabs is an
ExpandableListViewActivity. My application is using SQL Lite to store the
data bound to the ExpandableListView. When I change the SQL Lite data in
another activity, I need to refresh the ExpandableListView and show the new
data. If I am drawing the tab for the first time after adding new data, the
list shows correctly after the tab switch. If I am in the
ExpandableListViewActivity when I add new data to the list or edit existing
data, then I do not see the change. In this case, when I exit the
application and restart, I see the modified data was stored in SQL Lite as
expected. Can anyone suggest how I might get the tab to redraw the list?
The partially working code looks like this:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent
intent) {
super.onActivityResult(requestCode, resultCode, intent);
//stuff deleted
if((requestCode == EDITOR) && resultCode==RESULT_OK) {
tabs.setCurrentTab(1);
tabs.getCurrentView().invalidate();
}
}
The constructor for the list adapter is where I execute the code to populate
the groups and children. Do I want to drop and create a new list adapter?
That seems like a waste of perfectly good rows. Is it something I should do
in the ExpandableListViewActivity, rather than the TabHost? The fact that
this is an expandable list is probably irrelevant; I am stuck where an
object on the screen that has changed is not redrawn automatically.
Your help is deeply appreciated.
Best regards,
Beth
