如何获取dateformat以大写日期和月份

我像这样修复它：

        final CharSequence date = DateFormat.format(mDateFormat, mCalendar);    final CharSequence day = DateFormat.format(mDayFormat, mCalendar);    String time = (String) DateFormat.format(mTimeFormat, mCalendar);    RemoteViews views = new RemoteViews(getPackageName(), R.layout.clock2by2);    String days = new String(day.toString().substring(0,1).toUpperCase() + day.toString().substring(1));    String dates = new String(date.toString().substring(0,1).toUpperCase() + date.toString().substring(1));    views.setTextViewText(R.id.Day, days);    views.setTextViewText(R.id.Date, dates);    views.setImageViewBitmap(R.id.TimeView, buildUpdate(time));
