2020-04-01T16:54:14.357+0000時間處理轉換爲yyyy-MM-dd HH:mm:ss

從數據庫拿到的數據是2020-04-01T16:54:14.357+0000，頁面要顯示成yyyy-MM-dd HH:mm:ss格式，先轉換成字符串在轉換，具體如下

String old_time ="2020-04-01T16:54:14.357+0000";

 DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
 Date date = df.parse(old_time);
 SimpleDateFormat df1 = new SimpleDateFormat("EEE MMM dd HH:mm:ss Z yyyy", Locale.UK);
  Date date1 = df1.parse(date.toString());
  DateFormat df2 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
  old_time = df2.format(date1);
  Log.e("aaa", "時間" + old_time);

Date轉string

Date startday = new Date();
DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
String s = df.format(startday);

String轉Date

String dateStr = "2020-04-01 17:10:05";
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = sdf.parse(str);
