Calculer l'âge à partir de la date de naissance
J'ai la boîte de dialogue DatePicker, lorsque je sélectionne la date à ce moment-là, je veux calculer l'âge, mais quand je sélectionne la date de l'année en cours, il affiche l'âge -1 au lieu de 0, comment résoudre ce problème? S'il vous plaît aidez-moi à le résoudre . Mon code est ci-dessous:
public int getAge(int year, int month, int day) {
GregorianCalendar cal = new GregorianCalendar();
int y, m, d, noofyears;
y = cal.get(Calendar.YEAR);// current year ,
m = cal.get(Calendar.MONTH);// current month
d = cal.get(Calendar.DAY_OF_MONTH);// current day
cal.set(year, month, day);// here ur date
noofyears = (int) (y - cal.get(Calendar.YEAR));
LOGD("Age......", String.valueOf(noofyears));
if ((m < cal.get(Calendar.MONTH)) || ((m == cal.get(Calendar.MONTH)) && (d < cal.get(Calendar.DAY_OF_MONTH)))) {
--noofyears;
}
LOGD("Age......", String.valueOf(noofyears));
if (noofyears != 0) {
ageCount = noofyears;
} else {
ageCount = 0;
}
if (noofyears < 0)
throw new IllegalArgumentException("age < 0");
return noofyears;
}
Voici une méthode Java appelée getAge qui prend des nombres entiers pour l'année, le mois et le jour et renvoie un type String contenant un nombre entier représentant l'âge en années.

age--;
}

String ageS = ageInt.toString();
return ageS;
}
private boolean getAge(int year, int month, int day) {
try {
Calendar dob = Calendar.getInstance();

après que créer une classe

C’est ainsi que j’ai implémenté dans mon code source que j’ai testé J'espère que c'est utile:

Maintenant pour kotlin Langue:

var age = today.get(Calendar.YEAR) - dob.get(Calendar.YEAR)
if (today.get(Calendar.DAY_OF_YEAR) < dob.get(Calendar.DAY_OF_YEAR)) {
age--
}
val ageInt = age + 1
return ageInt.toString()
}
