Yeah - works like a charm!
Thanks, Justin!
Here the code snippets for others to reuse:
public class ProjectList extends ExpandableListActivity
implements AdapterView.OnItemSelectedListener
...
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ExpandableListView listView = getExpandableListView() ;
listView.setOnItemSelectedListener(this) ;
...
}
...
//-- Callback when an (group) item is selected in the list
public void onItemSelected(AdapterView arg0, View arg1, int
arg2, long arg3) {
Log.d( Constants.LOG_TAG, "onItemSelected()" );
...
}
//-- Callback when nothing is selected in the list
public void onNothingSelected(AdapterView arg0) {
Log.d( Constants.LOG_TAG, "onNothingSelected()" );
}
