如何获取dateformat以大写日期和月份

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?

回答:

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));
