Question

我正在尝试使用JXL从我的Android设备修改xls文件。如果我很好理解，第一步是复制工作簿。这是我的代码，在写入时抛出异常：

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...任何想法？

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);

Answer 2

在我的情况下，问题是由复制工作表和设置一些工作簿设置引起的。我使用这些设置作为openWorkbook函数和createWorkbook函数的参数。从createWorkbook函数中删除它们解决了我的问题。

//Load template workbook with settings
WorkbookSettings ws = new WorkbookSettings();
ws.setEncoding("Cp1252");

Workbook templateWorkbook = Workbook.getWorkbook(this.context.getAssets().open("template.xls"), ws);

//Create new workbook from templateWorkbook without settings
this.workbook = Workbook.createWorkbook(new File(this.location), templateWorkbook);
