java - android 数组索引越界

Question

我有一个字符串数组，它以“2012-04-26T08:38:00”的格式存储日期。我需要两个时间差，所以我从“T”中分割字符串并将其存储在数组中 所以现在

at array index 0 = 2012-04-26
and array index 1 = 08:38:00

现在从第一个索引开始，我用“:”分割，所以它的存储方式如下

[0] = 08
[1] = 38
[2] = 00

现在，当我从中减去当前时间时，昨天它给了我很好的输出，但现在它引发了错误。

Java 可以为您解析字符串。

String dateString = "2012-04-26T08:38:00";
SimpleDateFormat parser = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
Date date = null;
try {
    date = parser.parse(dateString);
} catch (ParseException e) {
    // error parsing.
}
if (date != null) {
    // do something with date.
}
