我不知道为什么使用POI编写的文件无法被Microsoft Excel 2013打开,但该文件仍可被POI读取。(单元格值可更改)
这里是文件中出现的错误。
以下是代码:
FileInputStream fis = null;
try {
fis = new FileInputStream(fileUri); //not error at fileUri
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
String urii = fileUri.replace(".xls", "0.xls"); //not error
File fisx = new File(urii);
Workbook workbook = null;
workbook = new HSSFWorkbook(fis);
Sheet sheet = workbook.getSheetAt(0);
Row row = sheet.getRow(0);
Cell cell = row.getCell(0);
String p = cell.getStringCellValue();
TextView a = (TextView) findViewById(R.id.txtUri);
cell.setCellValue(new String("popo"));
String x = cell.getStringCellValue();
TextView b = (TextView) findViewById(R.id.txtFile);
a.setText(p);
b.setText(x);
OutputStream fos = null;
fos = new FileOutputStream(fisx);
workbook.write(fos); //main problem
fos.flush();
fos.close();
谢谢您的帮助!!
