Hi,
I posted this on another forum it might be of help and you might be
able to answer questions!!
Very pleased :) with the way ExpandableListView works but am unclear
how to set the clicked view as invalid.
In the onChildClick(ExpandableListView parent, View v, int
groupPosition, int childPosition, long id)
{
I call the Dialog "Enter" and wait for dismiss so:-
Value = new Value_Input(test2.this,0, custno, itemno, day);
Value.show();
Value.setOnDismissListener(new OnDismissListener() {
public void onDismiss(DialogInterface arg0) {
getExpandableListView().invalidateViews();
}
});
}
the invalidateViews() seems a bit heavyweight when I only want to
redraw the clicked view.
(it also has side effects (mine) which I want to avoid. ) :(
the other options are:-
getExpandableListView().invalidate();
getExpandableListView().invalidate(dirty);
getExpandableListView().invalidate(l, t, r, b)
getExpandableListView().invalidateChild(child, dirty)
getExpandableListView().invalidateChildInParent(location, dirty)
getExpandableListView().invalidateDrawable(drawable)
basically how do I get from groupPosition, childPosition to the View
after the event??
or how to use one of the above??
any suggestions would gratefully received!!

Alas there is more - I have a command to expand the group and move it
to the top of the display:-
case 1:// "Move to Top")
getExpandableListView().setSelectedGroup(groupPosition);
getExpandableListView().expandGroup(groupPosition);
getExpandableListView().invalidateViews();
break;
This does not cause the children to be redrawn indeed there is no
subsequent call to getChildrenCount(int groupPosition)
getExpandableListView().setSelectedGroup(groupPosition); <- I was
hoping this might move group to top of screen!
