I’m using SimpleCursorTreeAdapter for ExpandableListView. The problem is once groupCursor is utilised, then ingetChildCursor(Cursor groupCursor)groupCursor is returning unexpected columns, the columns in groupCursor are replaced with Child Cursor’s columns.

I am unable to trace why the group cursor column’s are replaced with child column’s. And is it a good way to use SimpleCursorTreeAdapter to bind database with ExpandableListView.

I am trying different ways from past 3 days in CursorTreeAdapter and SimpleCursorTreeAdapter.

Please find the below screenshots for more detailed explanation.

Constructor initialized correctly with cursor having 3 columns

In getChidrenCount(), returning correct results upto some iterations.You can see the column’s in debug are still 3

After some iterations,the column values are changed. This is where the total problem is..

Suggest me the Best possible solutions.

Thanks & Regards,
Sha.
