Hi, 1 - You are most likely seeing issues caused by the list view "recycling" item views. An ExpandableListView is a subclass of ListView, and item view recycling is common to both of them.
Look it up, there are plenty of tutorials. The main thing is to always set your child view's state completely in getChildView, even if convertView != null. 2 - You could set a tag in the checkbox or the root of your child item layout, and use it to refer back to the data item (a database row or an in-memory object). Look up View.setTag. -- Kostya 2011/6/7 juliagrig <[email protected]> > Hi All, > I am working in an expandable list view by an simple expandable list > adapter.
