how to get dateformat to capitalize month and day

问题

I have my strings like so in my strings.xml:

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

And I use them like this in the code:

    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();
}

But it displays the day and the month in lowercase, and I want it to capitalize both. How can I achieve that?

回答1:

You can use WordUtils.capitalize(..) from commons-lang (on the result string)

(this is in case you want to capitalize - i.e. uppercase only the first letter. Otherwise you can simpyl use .toUpperCase())

Update: Since it appears this is android, you can open the sources of WordUtils and copy the implementation from there, rather than getting the whole library.

String's toUpperCase() ?

I fixed it like so:

        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));
