Expandable Listview With Sqlite Data

问题

I want to create an expandable listview that gets data from a table in Sqlite Database.

The table is Named as Consumer table.

I want the Account Number and Consumer Name to be the Parent.

I've watched lots of tutorials but all data are static and not from Sqlite Database.

can someone help me with this? thank you..
