模仿微博信息更新的时间：刚刚，10分钟前，半小时前，一天前

 榜样微博信息更新的时间：刚刚，10分钟前，半小时前，一天前

1.首先设置每一个阶段的时间：

           private static final int seconds_of_1minute = 60;

private static final int seconds_of_30minutes = 30 * 60;

private static final int seconds_of_1hour = 60 * 60;

private static final int seconds_of_1day = 24 * 60 * 60;

private static final int seconds_of_15days = seconds_of_1day * 15;

private static final int seconds_of_30days = seconds_of_1day * 30;

private static final int seconds_of_6months = seconds_of_30days * 6;

private static final int seconds_of_1year = seconds_of_30days * 12;

2.详细推断的方法：

  

        /**
* @return timtPoint距离如今经过的时间，分为
*         刚刚。1-29分钟前，半小时前。1-23小时前，1-14天前，半个月前，1-5个月前，半年前，1-xxx年前
*/
public String getTimeElapse() {

long nowTime = new Date().getTime() / 1000;

                //createTime是发表文章的时间

long oldTime = createTime;

                //elapsedTime是发表和如今的间隔时间

long elapsedTime = nowTime - oldTime;

if (elapsedTime < seconds_of_1minute) {

return "刚刚";
}
if (elapsedTime < seconds_of_30minutes) {

return elapsedTime / seconds_of_1minute + "分钟前";
}
if (elapsedTime < seconds_of_1hour) {

return "半小时前";
}
if (elapsedTime < seconds_of_1day) {

return elapsedTime / seconds_of_1hour + "小时前";
}
if (elapsedTime < seconds_of_15days) {

return elapsedTime / seconds_of_1day + "天前";
}
if (elapsedTime < seconds_of_30days) {

return "半个月前";
}
if (elapsedTime < seconds_of_6months) {

return elapsedTime / seconds_of_30days + "月前";
}
if (elapsedTime < seconds_of_1year) {

return "半年前";
}
if (elapsedTime >= seconds_of_1year) {

return elapsedTime / seconds_of_1year + "年前";
}

return "";
}
