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.这是我在编写时抛出异常的代码：

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……任何想法？

非常感谢

解决方法:

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);
