Compare android time slot

Question

I have a register where the establishment puts its opening hours in variables String, Ex: horario_abertura and horario_fechamento format: 00:00 24hrs.

I need the application to compare the current time with the opening and closing of the establishment, to inform if it is open or closed!

Does anyone have an example?

You can do it like this:

public static final String inputFormat = "HH:mm";

private Date date;
private Date dateCompareOne;
private Date dateCompareTwo;

private String horarioabertura = "8:45";
private String horariofechamento = "18:45";

SimpleDateFormat inputParser = new SimpleDateFormat(inputFormat, Locale.US);

private void compareDates(){
    Calendar now = Calendar.getInstance();

    int hour = now.get(Calendar.HOUR_OF_DAY);
    int minute = now.get(Calendar.MINUTE);

    date = parseDate(hour + ":" + minute);
    dateCompareOne = parseDate(horarioabertura);
    dateCompareTwo = parseDate(horariofechamento);

    if ( dateCompareOne.before( date ) && dateCompareTwo.after(date)) {
        //esta aberto
    } else
        //esta fechado
}

private Date parseDate(String date) {

    try {
        return inputParser.parse(date);
    } catch (java.text.ParseException e) {
        return new Date(0);
    }
}
