Question

所以我从MySQL数据库获取时间戳，格式如下：2014-12-09 16:46:26

我想在将该日期应用于TextView之前 - 检查日期是今天还是昨天。基本上就像：

if(timestamp == today){
TextView = "Today";
}
else if(timestamp == yesterday){
TextView = "Yesterday";
}
else{
TextView = FormatTimeStamp(DD/MM/YY hh:mm);
}

我写的是这段代码：

String dats = timestamp; //2014-12-09 16:46:26
String[] datsdt = dats.split("\\s+");
String[] dateSplit = datsdt[0].split("\\-");
String[] timeSplit = datsdt[1].split("\\:");
int year = Calendar.getInstance().get(Calendar.YEAR);
int month = Calendar.getInstance().get(Calendar.MONTH);
int day = Calendar.getInstance().get(Calendar.DATE);

然后将拆分日期部分与当前年月和日进行比较，但这似乎太长了，我确信这样做的方法不对。

那我该怎么做？

使用SimpleDateFormat解析日期和日历以比较日期。：

    SimpleDateFormat sdf = new SimpleDateFormat("yyy-MM-dd hh:mm:ss");
    Date date = sdf.parse("2014-12-09 16:46:26");

    Calendar c = Calendar.getInstance();
    c.setTime(date);
    c.set(Calendar.HOUR_OF_DAY,0);
    c.set(Calendar.MINUTE,0);
    c.set(Calendar.SECOND,0);
    c.set(Calendar.MILLISECOND,0);
    Calendar yesterday = Calendar.getInstance();
    yesterday.add(Calendar.DAY_OF_MONTH, -1);
    yesterday.set(Calendar.HOUR_OF_DAY,0);
    yesterday.set(Calendar.MINUTE,0);
    yesterday.set(Calendar.SECOND,0);
    yesterday.set(Calendar.MILLISECOND,0);

    if (c.getTime().equals(new Date())){
        //TODAY
    } else if (c.equals(yesterday)) {
        //yesterday
    } else {
        SimpleDateFormat sdf1 = new SimpleDateFormat("dd-MM-yyyy hh:mm");
        TextView  = sdf1.format(date);
    }

Android：检查MySQL时间戳是今天还是昨天ELSE输出格式化的时间戳
