Как динамически изменить заголовок веб-страницы?

Надеюсь, это поможет. Я использовал библиотеку времени Joda.

public class RangeTimePicker extends TimePicker implements
        TimePicker.OnTimeChangedListener {

    private int mMinHour = -1;

    private int mMinMinute = -1;

    private int mMaxHour = 25;

    private int mMaxMinute = 61;

    private int mCurrentHour;

    private int mCurrentMinute;


    public RangeTimePicker(Context context) {
        super(context);
        setOnTimeChangedListener(this);
    }

    public RangeTimePicker(Context context, AttributeSet attrs) {
        super(context, attrs);
        setOnTimeChangedListener(this);
    }

    public RangeTimePicker(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        setOnTimeChangedListener(this);
    }

    public void setMaxTime(int hourIn24, int minute) {
        mMaxHour = hourIn24;
        mMaxMinute = minute;

        LocalTime currentTime = LocalTime.now();
        LocalTime maxTime = new LocalTime(mMaxHour, mMaxMinute);

        if (currentTime.isAfter(maxTime)) {
            this.setCurrentHour(mCurrentHour = currentTime.getHourOfDay());
            this.setCurrentMinute(
                    mCurrentMinute = currentTime.getMinuteOfHour());
        }

    }

    public void setMinTime(int hourIn24, int minute) {
        mMinHour = hourIn24;
        mMinMinute = minute;

        LocalTime currentTime = LocalTime.now();
        LocalTime minTime = new LocalTime(mMinHour, mMinMinute);

        if (currentTime.isBefore(minTime)) {
            this.setCurrentHour(mCurrentHour = minTime.getHourOfDay());
            this.setCurrentMinute(mCurrentMinute = minTime.getMinuteOfHour());
        }
    }


    @Override
    public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
        boolean validTime = true;
        if (hourOfDay < mMinHour || (hourOfDay == mMinHour
                && minute < mMinMinute)) {
            validTime = false;
        }

        if (hourOfDay > mMaxHour || (hourOfDay == mMaxHour
                && minute > mMaxMinute)) {
            validTime = false;
        }

        if (validTime) {
            mCurrentHour = hourOfDay;
            mCurrentMinute = minute;
        }

        setCurrentHour(mCurrentHour);
        setCurrentMinute(mCurrentMinute);

    }
}
