如何从Android中的谷歌帐户日历获取事件？

Question

我正在使用此代码并从日历中获取事件并且它工作正常但我想从谷歌帐户日历中获取事件。例如，我想获取（deepakcando90@gmail.com）谷歌日历账户事件也？我知道这是可能的，但不知道如何实现它？

我的代码是，

public static void readCalendarEvent(Context context) throws ParseException {
        ContentResolver contentResolver = context.getContentResolver();
        Calendar calendar = Calendar.getInstance();
        String dtstart = "dtstart";
        String dtend = "dtend";


        SimpleDateFormat    displayFormatter = new SimpleDateFormat("EEEE, MMMM dd, yyyy");

         stime=displayFormatter.format(calendar.getTime());     

        SimpleDateFormat startFormatter = new SimpleDateFormat("MM/dd/yy");
        String dateString = startFormatter.format(calendar.getTime());

        long after = calendar.getTimeInMillis();
        SimpleDateFormat formatterr = new SimpleDateFormat("hh:mm:ss MM/dd/yy");
        Calendar endOfDay = Calendar.getInstance();
        Date dateCCC = formatterr.parse("47:59:59 " + dateString);
        endOfDay.setTime(dateCCC);



        cursor = contentResolver.query(Uri.parse("content://com.android.calendar/events"), (new String[] { "calendar_id", "title", "description", "dtstart", "dtend", "eventLocation" }), "(" + dtstart + ">" + after + " and " + dtend + "<" + endOfDay.getTimeInMillis() + ")", null, "dtstart ASC");
        gCalendar = new ArrayList<GoogleCalendar>();
        try {
            System.out.println("Count=" + cursor.getCount());

            if (cursor.getCount() > 0) {

                System.out.println("the control is just inside of the cursor.count loop");
                while (cursor.moveToNext()) {
                    GoogleCalendar googleCalendar = new GoogleCalendar();
                    gCalendar.add(googleCalendar);
                    int calendar_id = cursor.getInt(0);
                    googleCalendar.setCalendar_id(calendar_id);
                    String title = cursor.getString(1);
                    googleCalendar.setTitle(title);
                    String description = cursor.getString(2);
                    googleCalendar.setDescription(description);
                    String dtstart1 = cursor.getString(3);
                    googleCalendar.setDtstart(dtstart1);
                    String dtend1 = cursor.getString(4);
                    googleCalendar.setDtend(dtend1);
                    String eventlocation = cursor.getString(5);
                    googleCalendar.setEventlocation(eventlocation);

                }
            }
        } catch (AssertionError ex) {
            ex.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
