转换日期格式时发生崩溃

试试这个

SimpleDateFormat input = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS");

SimpleDateFormat output = new SimpleDateFormat("dd/MM/yyyy");
SimpleDateFormat output1 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss Z");

Date d = null;
try 
{
      d = input.parse("2018-01-23T00:00:00.000-05:00");

} 
catch (ParseException e) 
{
    e.printStackTrace();
}
String formatted = output.format(d);
Log.i("DATE", "" + formatted);

String formatted1 = output1.format(d);
Log.i("DATE1", "" + formatted1);

输出

I/DATE: 23/01/2018

I/DATE1: 2018-01-23 00:00:00 +0530

下面是您想要实现的工作片段:

public class FormatDateExample {
    public static void main(String[] args) {
        String date =  "2016-02-26T00:00:00+02:00";
        System.out.println(formatDate(date));

    }

    public static String formatDate(String unFormattedTime) {
         String formattedTime;
         try {
             SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
             Date date = sdf.parse(unFormattedTime);

             sdf = new SimpleDateFormat("dd MMM HH:mm");
             formattedTime = sdf.format(date);

             return formattedTime;

        } catch (ParseException e) {
             e.printStackTrace();
        }

        return "";
    }
}

首先,必须使用给定的格式解析日期

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
Date date = sdf.parse(unFormattedTime);

然后您必须将该日期格式化为所需格式“dd MMM HH:mm”

sdf = new SimpleDateFormat("dd MMM HH:mm");
formattedTime = sdf.format(date);
