Как мне сохранить свои данные в электронной таблице?

Question

Я хотел бы, чтобы мои сотрудники заполняли это в конце каждого дня.Как я смогу сохранять данные за каждый день в новую таблицу?Однажды я также попытаюсь сделать пользовательский интерфейс для удобства использования.Кстати, он еще далеко не закончен, все же необходимо добавить способ сохранения двух наборов данных за один день, поскольку в один и тот же день могут работать два гонщика.И пока не обнаружено ошибок.

Answer 1

Вы можете воспользоваться помощью APACHE POI , чтобы записать свои данные в электронную таблицу.

Смотрите здесь - https://www.tutorialspoint.com/apache_poi/apache_poi_spreadsheets.htm

Короче говоря, логика поможет вам добавить электронную таблицу в существующий файл Excel.

HSSFWorkbook workbook = null; // creating a new workbook
File file = new File(context.getExternalFilesDir(null), "Sample.xls"); //getting a file with this name if not exist will create a new excel file with this in below steps
FileOutputStream fileOut = new FileOutputStream(file); // output stream is used to write to a file

if (file.exists()) { // if file exists add a new workbook to it 
    try {
        workbook = (HSSFWorkbook)WorkbookFactory.create(file);
    } catch (InvalidFormatException e) {
        e.printStackTrace();
    }
    //add logic to convert the input to excel rows and write it into a wrokbook like this
    HSSFSheet sheet = workbook.createSheet("Sample sheet2");

}
else{ // create a new workbook
    workbook = new HSSFWorkbook();
    // for the first time if nothing is there this will execute 
    //add logic to convert the input to excel rows and write it into a wrokbook like this
    HSSFSheet sheet = workbook.createSheet("Sample sheet1");
}
workbook.write(fileOut); // closing the workbook after all operations
fileOut.close(); // closing the output stream

Это может показаться немного сложным, если вы не знакомы с JAVA, но я бы порекомендовал вам задавать вопросы, если что-то здесь не имеет смысла.

Answer 2

Вы можете использовать связанные с poi зависимости ， так же, как это

 WritableWorkbook book = Workbook.createWorkbook(new File("c:\\test.xls"));
 WritableSheet sheet = book.createSheet("sheet1", 0);
 Label label = new Label(0, 0, "test");
 sheet.addCell(label);
 jxl.write.Number number = new jxl.write.Number(1, 0, 555.12541);
 sheet.addCell(number);
 book.write();
 book.close();

Это может редактировать Windows Excel, вы можете узнать, связанные с poi операций через Google. Конечно, я думаю, что лучший способ - создать веб-проект с помощью javaEE
