android的Joda时间导致IllegalArgumentException

Question

说明:下面的方法应该从Firestore获取最后库存计数的日期，并执行procedwithinventorymode ()如果已经超过24小时

private void checkIf24HourReached() {
LocalDateTime now = LocalDateTime.now();
LocalDateTime _24hrsBefore = now.minusDays(1);
db.collection("Project").document(Prefs.getString("ManageID",
GlobalObject._FIRESTORE_ID))
.collection("inventoryMode")
.document(GlobalObject._INVENTORY_MODE_DATA_ID)
.get()
.addOnSuccessListener(documentSnapshot -> {
String lastInventoryEndDate = documentSnapshot.getString("date");
Log.d("lastInventoryEndDate: ", lastInventoryEndDate);
if (lastInventoryEndDate == null) {
proceedWithInventoryMode();
} else {
if (lastInventoryEndDate.isEmpty()) {
proceedWithInventoryMode();
}
LocalDateTime lastInventoryDate = new LocalDateTime(lastInventoryEndDate);
if (_24hrsBefore.isAfter(lastInventoryDate)) {
proceedWithInventoryMode();
} else {
Toast.makeText(getContext(),
"Last Inventory ended less than a day ago.",
Toast.LENGTH_LONG).show();
Toast.makeText(getContext(),
"Last date: " + lastInventoryEndDate,
Toast.LENGTH_LONG).show();
}
}
})
.addOnFailureListener(e -> Toast.makeText(getContext(),
"Date couldn't be read.",
Toast.LENGTH_LONG).show());
}

问题:我得到一个IllegalArgumentException。onSuccess()中的日志语句语句打印:"lastInventoryEndDate:: 13/07/2022 09:57:11"。但是错误日志如下:

知道怎么解决这个问题吗?谢谢你。

Answer 1

您没有包含实际解析的代码，但我假设它与您的日期不在ISO8601格式有关。您必须提供一个自定义格式化程序，用于将字符串解析为适当的日期和时间对象。

在您的例子中，您可以创建一个自定义格式化器

val formatter = DateTimeFormat.forPattern(“dd/MM/yyyy HH:mm:ss”)

用它来解析你的日期

val dateTime = LocalDateTime.parse(dateTimeString, formatter);
