Android TimePickerDialog défini le temps maximum
Je cherche un moyen de définir les options de durée maximale et minimale sélectionnables sur une Android TimePickerDialog, et de modifier l'intervalle de minutes par défaut de 1 minute à 5 minutes,
Je pensais que c'était facile, mais je ne peux pas trouver un moyen!
CETTE REPONSE IS SURETE
Cela ne fonctionnera pas sur Android 5 ou supérieur.
Ceci est une extension de fiddlers answer . D'une façon ou d'une autre, onTimeChangedListener n'est pas défini par TimePickerDialog dans certaines versions Android:
La méthode onTimeChanged n’appelle jamais cette méthode! La meilleure solution à ce problème consiste à coder un TimePickerDialog personnalisé avec la logique min/max de fiddler.
Le travail le plus moche est celui-ci. (Ajout de l'auditeur à l'aide de réflexions) Je met également à jour le titre pour afficher l'heure actuellement sélectionnée.

Pour lolipop et les versions supérieures d’Android, vous pouvez utiliser cette classe RangeTimePickerDialog modifiée.
(À partir de lolipop, Timepicker utilise le mode d'horloge (conception de matériau) par défaut pour que l'ancienne classe personnalisée ne fonctionne pas. Nous pouvons modifier le mode en mode spinner pour la dernière version et réutiliser la classe.)

Vous pouvez utiliser cela comme point de départ.
J'ai étendu TimePickerDialog et ajouté 2 méthodes setMin et setMax.
Dans la méthode onTimeChanged, je vérifie que la nouvelle heure est valide par rapport aux temps min/max.
Il faut encore du polissage ...
public class BoundTimePickerDialog extends TimePickerDialog {
private int minHour = -1, minMinute = -1, maxHour = 100, maxMinute = 100;
private int currentHour, currentMinute;
public BoundTimePickerDialog(Context context, OnTimeSetListener callBack, int hourOfDay, int minute, boolean is24HourView) {
super(context, callBack, hourOfDay, minute, is24HourView);
}
public void setMin(int hour, int minute) {
minHour = hour;
minMinute = minute;
}
public void setMax(int hour, int minute) {
maxHour = hour;
maxMinute = minute;
}
@Override
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
super.onTimeChanged(view, hourOfDay, minute);
boolean validTime;
if(hourOfDay < minHour) {
validTime = false;
}
else if(hourOfDay == minHour) {
validTime = minute >= minMinute;
}
else if(hourOfDay == maxHour) {
validTime = minute <= maxMinute;
}
else {
validTime = true;
}
if(validTime) {
currentHour = hourOfDay;
currentMinute = minute;
}
else {
updateTime(currentHour, currentMinute);
}
}
}
Il n'y a pas de méthode native pour définir le temps maximum/minimum, mais peut-être que si vous étendez onTimeChanged ou updateTime, vous pouvez empêcher le temps d'être défini sur une valeur en dehors de vos limites.
Après le code de violoniste re-factorisé:
public class RangeTimePickerDialog extends TimePickerDialog {
private int mMinHour = -1;
private int mMinMinute = -1;
private int mMaxHour = 100;
private int mMaxMinute = 100;
private int mCurrentHour;
private int mCurrentMinute;
public RangeTimePickerDialog(Context context, OnTimeSetListener callBack, int hourOfDay,
int minute, boolean is24HourView) {
super(context, callBack, hourOfDay, minute, is24HourView);
mCurrentHour = hourOfDay;
mCurrentMinute = minute;
// Somehow the onTimeChangedListener is not set by TimePickerDialog
// in some Android Versions, so, Adding the listener using
// reflections
try {
Class<?> superclass = getClass().getSuperclass();
Field mTimePickerField = superclass.getDeclaredField("mTimePicker");
mTimePickerField.setAccessible(true);
TimePicker mTimePicker = (TimePicker) mTimePickerField.get(this);
mTimePicker.setOnTimeChangedListener(this);
} catch (NoSuchFieldException e) {
} catch (IllegalArgumentException e) {
} catch (IllegalAccessException e) {
}
}
public void setMin(int hour, int minute) {
mMinHour = hour;
mMinMinute = minute;
}
public void setMax(int hour, int minute) {
mMaxHour = hour;
mMaxMinute = minute;
}
@Override
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
super.onTimeChanged(view, hourOfDay, minute);
boolean validTime;
if (((hourOfDay < mMinHour ) || (hourOfDay == mMinHour && minute < mMinMinute))
|| ((hourOfDay > mMaxHour) || (hourOfDay == mMaxHour && minute > mMaxMinute))) {
validTime = false;
} else {
validTime = true;
}
if (validTime) {
mCurrentHour = hourOfDay;
mCurrentMinute = minute;
} else {
updateTime(mCurrentHour, mCurrentMinute);
}
}
}
Vous pouvez simplement utiliser un TimePicker personnalisé avec reflect pour définir les valeurs.
@Override
protected void onAttachedToWindow() {
super.onAttachedToWindow();
try {
Class<?> classForid = Class.forName("com.Android.internal.R$id");
Field field = classForid.getField("minute");
NumberPicker mMinuteSpinner = (NumberPicker) findViewById(field.getInt(null));
mMinuteSpinner.setMinValue(5);
mMinuteSpinner.setMaxValue((60 / timeInterval) - 1);
List<String> displayedValues = new ArrayList<>();
for (int i = 0; i < 60; i += timeInterval)
displayedValues.add(String.format("%02d", i));
mMinuteSpinner.setDisplayedValues(displayedValues.toArray(new String[0]));
mMinuteSpinner.setWrapSelectorWheel(true);
} catch (Exception e) {
e.printStackTrace();
}
}
Ainsi, vous pouvez définir les valeurs que vous voulez
J'espère que ce travail fonctionnera parfaitement avec moi ...
Définir le temps maximum pour le sélecteur de temps.

}
//to set as 12 hour
time_format = (hourOfDay + ":" + minute + ":" + "00");

}

J'espère que cela pourrait être utile. J'ai utilisé la bibliothèque de temps Joda.
