I have a ExpandableListView with some groups, and each group haves only one
child, with a string on it.
I have a thread that get's some updated data and *each second* calls a
handler that updates the string of one of the childs of the
ExpandableListView and then calls this method to refresh the view and show
the updated data to the user: ((BaseExpandableListAdapter)
mAdapter).notifyDataSetChanged();
This is the update handler:
infoUpdateHandler = new Handler(){
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
children[2][0]=getUpdatedInfo();
((BaseExpandableListAdapter) mAdapter).notifyDataSetChanged();
}
};
The problem is that when i'm scrolling the expandable list view, i can see
how the scroll is showing low performance, it stops sometimes. I think that
it is because this call ((BaseExpandableListAdapter)
mAdapter).notifyDataSetChanged(); is updating all the ExpandableListView.
*Does not exist a better way to update a expandable list view? Maybe a way
to update only the child that you want to update?*
Thanks
