Can anyone guide me how to accomplish this task?

Answer 1

you need to remove the item from the position and then set the adapter again so that the list will be refreshed.

listofitems.remove(tempPosition);

setListAdapter(customAdapter );

to remove from the database. use the position to get the id.

c.moveToPosition(position);
         id= c.getInt(c.getColumnIndex("_id"));

using the id you can delete

myDataBase.delete(tablename, "_id=?", new String[] {Integer.toString(id)});
