public class DateUtil {    /**     * 将一个时间戳转换成提示性时间字符串，如刚刚，1秒前     */    public static String convertTimeToFormat(String timeStamp) {        long curTime =System.currentTimeMillis()/1000 ;        long time = curTime - Long.parseLong(timeStamp);        if (time < 60 && time >= 0) {            return "刚刚";        } else if (time >= 60 && time < 3600) {            return time / 60 + "分钟前";        } else if (time >= 3600 && time < 3600 * 24) {            return time / 3600 + "小时前";        } else if (time >= 3600 * 24 && time < 3600 * 24 * 30) {            return time / 3600 / 24 + "天前";        } else if (time >= 3600 * 24 * 30 && time < 3600 * 24 * 30 * 12) {            return time / 3600 / 24 / 30 + "个月前";        } else if (time >= 3600 * 24 * 30 * 12) {            return time / 3600 / 24 / 30 / 12 + "年前";        }else {            return curTime+"-"+Long.parseLong(timeStamp)*1000+"-"+time+"";        }    }    /**     * 时间戳转化为日期格式字符串     */    public static String timeStampToDate(String seconds, String format) {        if(seconds == null || seconds.isEmpty() || seconds.equals("null")){            return "";        }        if(format == null || format.isEmpty()) format = "yyyy-MM-dd HH:mm:ss";        SimpleDateFormat sdf = new SimpleDateFormat(format);        return sdf.format(new Date(Long.valueOf(seconds+"000")));    }    /**     * 日期格式字符串转换成时间戳     */    public static String dateToTimeStamp(String date_str, String format){        try {            SimpleDateFormat sdf = new SimpleDateFormat(format);            return String.valueOf(sdf.parse(date_str).getTime()/1000);        } catch (Exception e) {            e.printStackTrace();        }        return "";    }    /**     * 取得当前时间戳（精确到秒）     * @return     */    public static String timeStamp(){        long time = System.currentTimeMillis();        String t = String.valueOf(time/1000);        return t;    }    /**     * 取得指定日期时间戳（精确到秒）     * @return     */    public static String timeStamp1(String s) throws ParseException {        long time = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").parse(s).getTime();        String t = String.valueOf(time/1000);        return t;    }/** * 根据日期计算周几 * * @param strParams * @return */public static String caculateWeeks(String strParams) {    String Week = "";    SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");    Calendar c = Calendar.getInstance();    try {        c.setTime(format.parse(strParams));    } catch (Exception e) {        // TODO Auto-generated catch block        e.printStackTrace();    }    if (c.get(Calendar.DAY_OF_WEEK) == 1) {        Week += "天";    }    if (c.get(Calendar.DAY_OF_WEEK) == 2) {        Week += "一";    }    if (c.get(Calendar.DAY_OF_WEEK) == 3) {        Week += "二";    }    if (c.get(Calendar.DAY_OF_WEEK) == 4) {        Week += "三";    }    if (c.get(Calendar.DAY_OF_WEEK) == 5) {        Week += "四";    }    if (c.get(Calendar.DAY_OF_WEEK) == 6) {        Week += "五";    }    if (c.get(Calendar.DAY_OF_WEEK) == 7) {        Week += "六";    }    return Week;}
}

在Activity用法：

public class Main3Activity extends Activity {    private TextView tv1,tv2,tv3;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main3);        tv1= (TextView) findViewById(R.id.textView1);        tv2= (TextView) findViewById(R.id.textView2);        tv3= (TextView) findViewById(R.id.textView3);        try {            String timeStamp = DateUtil.timeStamp1("2010-12-25 11:54:00");            tv1.setText(DateUtil.timeStampToDate(timeStamp, "yyyy-MM-dd HH:mm:ss"));            tv2.setText(timeStamp+"=="+DateUtil.dateToTimeStamp(DateUtil.timeStampToDate(timeStamp, "yyyy-MM-dd HH:mm:ss"), "yyyy-MM-dd HH:mm:ss"));            tv3.setText(DateUtil.convertTimeToFormat(timeStamp));        } catch (ParseException e) {            e.printStackTrace();        }    }}
