问使用than循环向滚动视图中添加多个LinearLayout

EN

String query = "select * from restaurant";
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery(query);

LinearLayout data_big_layout, detail_data_layout;
TextView name, type_area, price_txt;

    data_scroll_view.addView(data_big_layout); //Cannot add data_big_layout in the next loop

    z = "Search successful";

}
isSuccess = true;
stmt.close();
rs.close();
con.close();
