Android 和 JXL : ArrayIndexOutOfBoundException when create WritableWorkbook

Question

我正在尝试使用 JXL 从我的 Android 设备修改一个 xls 文件。第一步，如果我已经很好地理解的话，就是复制工作簿。这是我在写入时抛出异常的代码:

java.io.File licencesFile = new java.io.File(LicencesService.getPath(mCtx) + "/" +   pFileName);
java.io.File licencesFiletmp = new java.io.File(LicencesService.getPath(mCtx) + "/" + pFileName + ".tmp");
is = new FileInputStream(licencesFiletmp);
os = new FileOutputStream(licencesFile);

Workbook workbookTmp = Workbook.getWorkbook(is);
WritableWorkbook workbookFinal = Workbook.createWorkbook(os, workbookTmp);

//TODO code will come here when it'll work.

workbookFinal.write(); // <= Here is thrown an Exception
workbookFinal.close();

我没有找到任何解决方案...有什么想法吗？

非常感谢

您需要指定写访问权限，如下所示:

WorkbookSettings settings = new WorkbookSettings();
settings.setWriteAccess("something");
WritableWorkbook workbook = Workbook.createWorkbook(out, Workbook.getWorkbook(getClass().getResourceAsStream("report.xls")),settings);
