读取Java Apache POI中的Excelcheckbox值
我花了无数小时试图find解决办法。 我已经尝试了Apache POI，JExcel和JXLS，但没有find代码来成功读取checkbox（表单控件）值。
如果有人find了工作解决scheme，那么如果你能在这里分享，那将是非常好的。 谢谢！
UPDATE
我已经编写了读取checkbox的代码，但是无法确定它是否被选中。

在你的例子中，你循环的SubRecords和你检查CommonObjectDataSubRecord 。 但是checkbox的值可以在SubRecord.UnknownSubRecord 。 这不幸是一个私人类，所以你不能调用任何方法，但toString()显示的数据，并用一个正则expression式值可以find。 所以使用下面的代码我设法检索checkbox的状态：
Pattern p = Pattern.compile("\\[sid=0x000A.+?\\[0(\\d),"); if (!(subRecord instanceof CommonObjectDataSubRecord)) { Matcher m = p.matcher(subRecord.toString()); if (m.find()) { String checkBit = m.group(1); if (checkBit.length() == 1) { boolean checked = "1".equals(checkBit); checkBox.setChecked(checked); } } }
现在我的挑战是检索xlsx文件中的checkbox值…
