Question

我有一个字符串，其中包含以"2014-11-12 16:19:00"格式从webservice检索的日期时间我只需要提取12小时格式AM或PM的时间。我试过但没有得到理想的结果。

public Date validateBreakingNewsDateDate() throws Exception{                            
        Date date = null;
        String dtStart = "2014-11-12 16:19:00";  
        SimpleDateFormat  format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");  
        try {  
             date= format.parse(dtStart);  
            Log.e("date", "kardate "+date); 
        } catch (ParseException e) {  
            // TODO Auto-generated catch block  
            e.printStackTrace();  
        }   
        return date;
}

Answer 1

尝试以下代码段

SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy     hh:mm:ss a");

Answer 2

将您的日期传递给此功能，它将返回时间

   public String setTime(String date) {
    final String OLD_FORMAT = "yyyy-MM-dd HH:mm:ss";
    final String NEW_FORMAT = "h:mm a";

    String newDate = "";
    try {
SimpleDateFormat sdf = new SimpleDateFormat(OLD_FORMAT);
        Date d = sdf.parse(date);
        sdf.applyPattern(NEW_FORMAT);
        newDate = sdf.format(d);
    } catch (ParseException e) {
        // TODO: handle exception
    }
    return newDate;
}

例如

 public String setTime(String date) {
    final String OLD_FORMAT = "yyyy-MM-dd HH:mm:ss";
    final String NEW_FORMAT = "h:mm a";

    String newDate = "";
    try {
        sdf = new SimpleDateFormat(OLD_FORMAT);
        Date d = sdf.parse("2014-11-12 16:19:00");
        sdf.applyPattern(NEW_FORMAT);
        newDate = sdf.format(d);
    } catch (ParseException e) {
        // TODO: handle exception
    }
    return newDate;
}

输出= 4:19 PM

Answer 3

试试这个......

DateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = format.parse(dtStart);
String newstring = new SimpleDateFormat("hh:mm aa").format(date);

Answer 4

您可以使用SimpleDateFormat获取12小时的时间，如下所示

Date date = null;
String dtStart = "2014-11-12 16:19:00";
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd KK:mm:ss");
try {
    date = format.parse(dtStart);
    Log.e("date", "kardate " + date);
    // here hh means hours in 12 hr format and a stands for AM/PM
    format = new SimpleDateFormat("hh:mm:ss a");
    String desiredTime= format.format(date);
    // You will get newDate 04:19:00 pm
    Log.e("date", "newDate " + desiredTime);
} catch (Exception e) {
    e.printStackTrace();
}
