Firs you should connect to your project these jars.

你应该把这些罐子连接到你的项目。

Then use this code for reading

然后使用此代码进行阅读

public static void readXLSXFile() throws IOException
    {
        InputStream ExcelFileToRead = new FileInputStream("C:/Test.xlsx");
        XSSFWorkbook  wb = new XSSFWorkbook(ExcelFileToRead);

        XSSFWorkbook test = new XSSFWorkbook(); 

        XSSFSheet sheet = wb.getSheetAt(0);
        XSSFRow row; 
        XSSFCell cell;

        Iterator rows = sheet.rowIterator();

        while (rows.hasNext())
        {
            row=(XSSFRow) rows.next();
            Iterator cells = row.cellIterator();
            while (cells.hasNext())
            {
                cell=(XSSFCell) cells.next();

                if (cell.getCellType() == XSSFCell.CELL_TYPE_STRING)
                {
                    System.out.print(cell.getStringCellValue()+" ");
                }
                else if(cell.getCellType() == XSSFCell.CELL_TYPE_NUMERIC)
                {
                    System.out.print(cell.getNumericCellValue()+" ");
                }
                else
                {
                    //U Can Handel Boolean, Formula, Errors
                }
            }
            System.out.println();
        }

    }

Updated your code to able to read and write the .XLSX and .XLS files

更新了您的代码，以便能够读取和写入.XLSX和.XLS文件

InputStream is = context.getAssets().open("sample.xlsx"));
Workbook workbook = WorkbookFactory.create(is);
Sheet sheet = workbook.getSheetAt(0);
Cell cell = sheet.getRow(0).getCell(0);
String value = cell.getStringCellValue() + "";
