数组索引超出绑定的android

标签： java android

我有一个字符串数组，其格式为“2012-04-26T08：38：00”。我需要两个时间差，所以我从“ T ”拆分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

现在从第一个索引我用“：”拆分，所以它像

一样存储 
[0] = 08
[1] = 38
[2] = 00

现在，当我减去当前的时间时，它昨天给了我很好的输出，但现在它引起错误。

Java可以为你解析字符串。

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.
}

这种情况正在发生，因为当您在ArrayList中只有1个元素时，您试图访问第二个索引（1），这意味着您唯一有效的索引是0。

错误的第一行告诉你这个...... 

`java.lang.ArrayIndexOutOfBoundsException: index=1 length=1`

这意味着在访问大小为1的ArrayList的索引号1时会遇到ArrayIndexOutOfBoundsException（意味着0是目前唯一包含内容的索引。）
