Solution 1:

You are referencing the node purchasebill, and then you are looping inside the direct children of purchasebill which are gameworld and datamination.

To solve your problem, you can add a reference to child datamination thus it won't loop inside gameworld, so you can do the following:

myRef.child("datamination").addValueEventListener(new ValueEventListener() {
    @Override
    publicvoidonDataChange(@NonNull DataSnapshot dataSnapshot) {
            billlistHelper = dataSnapshot.getValue(BilllistHelper.class);
            assert billlistHelper != null;
            account.add(billlistHelper.getAccount());
            amount.add(billlistHelper.getAmount());
            for (DataSnapshot dd : dataSnapshot.child("datedata").getChildren(){
                dateDataHelper = dd.getValue(DateDataHelper.class);

                date.add(dateDataHelper.getDate());
                month.add(dateDataHelper.getMonth());
                year.add(dateDataHelper.getYear());
            }
            intendby.add(billlistHelper.getIntendby());
            vendorname.add(billlistHelper.getVendorName());

        }
        billListAdapter.notifyDataSetChanged();

}
