在Android中转换为简单日期格式或Unix时间戳日期？

-1

我收到日期（2015-03-20T06：34：01.831183 + 01：00）从服务器这不是简单的日期格式，我想这种类型的日期转换为简单的日期格式一样（yyyyMMddHHmmssSSSS）在Android中转换为简单日期格式或Unix时间戳日期？

我该怎么做。我用这一点，但不是为我工作

String tdate="2015-03-15T14:04:43.877593+01:00";   
    SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss a"); 
    formatter.setTimeZone(TimeZone.getTimeZone("IST")); 
    String dateInString = "2015-03-15T14:04:43.877593+01:00";  

    try { 

     Date date = null; 
     try { 
      date = formatter.parse(dateInString); 
     } catch (java.text.ParseException e) { 
      e.printStackTrace(); 
     } 
     System.out.println(date); 
     System.out.println(formatter.format(date)); 
     System.out.println("System Date in GMT: "+formatDateToString(date, "yyyyMMddHHmmssSSSS", "IST")); 

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

错误的logcat

检查了这一点。希望这会有所帮助。我不读秒数（SSS）。

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss"); 
     formatter.setTimeZone(TimeZone.getTimeZone("IST")); 
     String dateInString = "2015-03-15T14:04:43.877593+01:00"; 

     SimpleDateFormat newDateFormat = new SimpleDateFormat("yyyyMMddHHmmssSSSS"); 

     Date date = null; 
     try { 
      //date instace 
      date = formatter.parse(dateInString); 
      //date format -> yyyyMMddHHmmssSSSS 
      String sNewDate = newDateFormat.format(date); 
      System.out.println("New Date Format " + sNewDate); 
     } catch (java.text.ParseException e) { 
      e.printStackTrace(); 
     }
