如何获取dateformat以大写日期和月份

Question

我的strings.xml中有这样的字符串：

<string name="day_format">EEEE</string>
<string name="date_format">dd. MMMM</string>
<string name="date_format_us">MMMM dd</string>

我在代码中像这样使用它们：

    private void reinit() {
    mDayFormat = getString(R.string.day_format);
    if (!DateFormat.is24HourFormat(this))
    {
    mDateFormat = getString(R.string.date_format_us);
    }
    else {
        mDateFormat = getString(R.string.date_format);
    }
    mTimeFormat = is24HourMode(this) ? FORMAT_24_HOURS : FORMAT_12_HOURS;
    mCalendar = Calendar.getInstance();
}

但是它以小写形式显示日期和月份，我希望将两者都大写。我该如何实现？

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));
