Question

我的字符串日期 - ＆gt; 2016-10-02T00:00:00.000Z。我想从这个字符串中只获取日期。我试图解析下面的编码，但它让我错误！我的格式与字符串中提到的格式完全相同。有什么答案吗？

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSZ");
        try {
            Date myDate = sdf.parse( dateofJoining.replaceAll( "([0-9\\-T]+:[0-9]{2}:[0-9.+]+):([0-9]{2})", "$1$2" ) );
            System.out.println("Date only"+ myDate );
        } catch (ParseException e) {
            e.printStackTrace();
        }

我也在代码下面累了，

SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");  
try {  
    Date date = format.parse(dtStart);  
    System.out.println(date);  
} catch (ParseException e) {  
    // TODO Auto-generated catch block  
    e.printStackTrace();  
}

我得到的错误

java.text.ParseException: Unparseable date: "2016-10-02T00:00:00.000Z" (at offset 19)

尝试

Calendar calendar = Calendar.getInstance();
TimeZone localTZ = calendar.getTimeZone();    
String format1 = "yyyy-MM-dd"; //will return 2017-01-31
String format2 = "dd"; //will return DAY only like 31
SimpleDateFormat sdf = new SimpleDateFormat(format);
sdf.setTimeZone(localTZ );
String result = sdf.format(your_date);

Answer 3

对我来说它是这样工作的：

textView_last_comm.setText(parseDateFormat(passDetailsModel.getLast_comm(), "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", "dd/MM/yy HH:mm"));

  public static String parseDateFormat(String dateToFormat, String inputFormat, String outputFormat) {
SimpleDateFormat inputFormat = new SimpleDateFormat(inputFormat);
SimpleDateFormat outputFormat = new SimpleDateFormat(outputFormat);

Date date = null;
String str = null;

try {
    date = inputFormat.parse(dateToFormat);
    str = outputFormat.format(date);
} catch (ParseException e) {
    e.printStackTrace();
}
return str;
}

Answer 4

您可以使用date方法轻松获得String.substring()：

String string = "2016-10-02T00:00:00.000Z";
String date = string.substring(0, 10);

Log.d("SUCCESS", "DATE: " + date);

<强>输出：

D/SUCCESS: DATE: 2016-10-02

解析yyyy-MM-dd＆＃39; HH：mm：ss在Android中的日期
