Динамически созданная TableRow, а затем RelativeLayout не отображается

Я перебираю результаты запроса, создающего RelativeLayouts в TableRows. Если я попытаюсь установить LayoutParams для RelativeLayout, ничего не появится и не будет ошибок. Если я этого не сделаю, все появится, но с макетом, установленным на WRAP_CONTENT. Я пробовал несколько примеров и не могу заставить его работать. Ниже мой код:

            TableLayout tblItems = (TableLayout) findViewById(R.id.tblItems);

            // Fields from the database (projection)
            String[] projection = new String[] { ItemsTable.ITEM_ID,
                                                ItemsTable.ITEM_NAME,
                                                ItemsTable.ITEM_PRICE,
                                                ItemsTable.ITEM_PICTURE };          
            Cursor cursor = getContentResolver().query(ItemsTable.CONTENT_URI, projection, null, null, null);                   
            startManagingCursor(cursor);        

            // Establish the item mapping
//          String[] columns = new String[] {"name", "price"};
//          int[] to = new int[] {R.id.tv_description, R.id.tv_price};

//          adapter = new SimpleCursorAdapter(this, R.layout.item_list_select, cursor, columns, to, 0);
//          lvSelectItems.setAdapter(adapter);

/*          
            adapter.setViewBinder(new SimpleCursorAdapter.ViewBinder() { 

                public boolean setViewValue(View view, Cursor cursor, int columnIndex) { 
                    if(columnIndex == cursor.getColumnIndexOrThrow(OrderDetailTable.ORDERDETAIL_PRICE)) { 

                  //          String createDate = aCursor.getString(aColumnIndex); 
                  //          TextView textView = (TextView) aView; 
                  //          textView.setText("Create date: " + MyFormatterHelper.formatDate(getApplicationContext(), createDate)); 

                            double total = cursor.getDouble(columnIndex);
                            TextView textView = (TextView) view;
                            textView.setText("$" + String.format("%.2f",dRound(total, 2)));

                            return true; 
                    } 
                    return false; 
                } 

            });
*/          
            // tblItems

            int totalRows = 0;
            int tcolumn = 1;

            int numItems = cursor.getCount();
            double tempRow = numItems / 2;

            if (numItems > 0) {
                itemsFound = true;

            boolean ifFirst = true;

            // Get user input
            iPart = (long) tempRow;
            fPart = tempRow - iPart;

            if (fPart > 0) {
                totalRows = (int) (iPart + 1);
            } else {

            }

            TableRow row = null;
