Android解析和格式化DateTime时间戳

Question

我需要Android/Java文本格式的帮助。我一直在努力解决如何从SQLite数据库解析和格式化Google DateTime字符串。错误是

E/TAG﹕ Parsing ISO8601 datetime failed
    java.text.ParseException: Unparseable date: "2015-08-04T18:20:00.000-04:00" (at offset 10)
            at java.text.DateFormat.parse(DateFormat.java:579)

我写的方法是

import java.util.Date;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.TimeZone;

…

public String formatDueDate(String queryResponse) {
        DateFormat iso8601Format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        Date date = new Date();
        try {
             date = iso8601Format.parse(queryResponse);
        } catch (ParseException e) {
            Log.e("TAG", "Parsing ISO8601 datetime failed", e);
        }
        long when = date.getTime();
        int flags = 0;
        flags |= android.text.format.DateUtils.FORMAT_SHOW_TIME;
        flags |= android.text.format.DateUtils.FORMAT_SHOW_DATE;
        flags |= android.text.format.DateUtils.FORMAT_ABBREV_MONTH;
        flags |= android.text.format.DateUtils.FORMAT_SHOW_YEAR;
       return android.text.format.DateUtils.formatDateTime(mContext,
                when + TimeZone.getDefault().getOffset(when), flags);
    }

try from

DateFormat iso8601Format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

DateFormat iso8601Format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
