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));
