Android 和 JXL : ArrayIndexOutOfBoundException when create WritableWorkbook

我正在尝试使用 JXL 从我的 Android 设备修改一个 xls 文件。第一步，如果我很好理解的话，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......知道吗？

非常感谢

最佳答案

在我的情况下，问题是由复制工作表并设置一些 WorkbookSettings 引起的。我将这些设置用作 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);
