将事件添加到日历时，Android Studio 将 ISO 字符串转换为

Question

我试图在将字符串“2018-10-17T22:00:00Z”作为事件添加到日历时将其转换为东部时区，但不是将事件时间添加为下午 6 点，而是将其添加为晚上 10 点。任何帮助，将不胜感激。String[] segments = uri.getPath().split("/");Date startDate = null;Date endDate = null;Activity activity = (Activity) context;String stTime = "2018-10-17T22:00:00Z";String enTime = "2018-10-17T23:00:00Z";String eventTitle = segments[3];String eventLocation = segments[4];TimeZone timezone = TimeZone.getTimeZone("America/New_York");SimpleDateFormat formatStart = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");formatStart.setTimeZone(timezone);SimpleDateFormat formatEnd = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");formatEnd.setTimeZone(timezone);try {    startDate = formatStart.parse(stTime);    endDate = formatEnd.parse(enTime);} catch (ParseException e) {    e.printStackTrace();}Calendar calStart = new GregorianCalendar(timezone);calStart.setTime(startDate);Calendar calEnd = new GregorianCalendar(timezone);calEnd.setTime(endDate);if (ActivityCompat.checkSelfPermission(this.context, android.Manifest.permission.WRITE_CALENDAR) != PackageManager.PERMISSION_GRANTED) {    ActivityCompat.requestPermissions(activity, new String[]{android.Manifest.permission.WRITE_CALENDAR},1);}Calendar beginTime = Calendar.getInstance();beginTime.set(calStart.get(Calendar.YEAR), calStart.get(Calendar.MONTH), calStart.get(Calendar.DAY_OF_MONTH), calStart.get(Calendar.HOUR_OF_DAY), calStart.get(Calendar.MINUTE));Calendar endTime = Calendar.getInstance();endTime.set(calEnd.get(Calendar.YEAR), calEnd.get(Calendar.MONTH), calEnd.get(Calendar.DAY_OF_MONTH), calEnd.get(Calendar.HOUR_OF_DAY), calEnd.get(Calendar.MINUTE));
