[英]AlarmManager going off everytime i open the app
我正在运行此代码以在创建方法的MainActivity中设置警报管理器
public void notificationCheck() {
calendar.set(Calendar.HOUR_OF_DAY, Preferences.getMorningHour(getApplicationContext()));
calendar.set(Calendar.MINUTE, Preferences.getMorningMinute(getApplicationContext()));
calendar.set(Calendar.SECOND, 0);
final PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, new Intent(this, AlarmReceiver.class), 0);
AlarmManager am = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
// Sets an alarm - note this alarm will be lost if the phone is turned off and on again
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
am.setAndAllowWhileIdle(AlarmManager.RTC, calendar.getTimeInMillis(), pendingIntent);
} else {
am.setRepeating(AlarmManager.RTC, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
}
}
因此,应将闹铃设置为每天上午10:00。闹铃工作良好,直到触发一次。 闹钟在10:00 AM完成后,每次我打开该应用程序时,它都会持续响起。
可以请我解释一下是否需要更改代码吗?
编辑:
我正在使用sharedPreferences设置日历实例的时间
首选项:
public static int getMorningHour(Context context) {
return PreferenceManager.getDefaultSharedPreferences(context).getInt(MORNING_HOUR, 9);
}
public static void setMorningHour(Context context, Integer morningHour) {
PreferenceManager.getDefaultSharedPreferences(context).edit().putInt(MORNING_HOUR, morningHour).apply();
}
public static int getMorningMinute(Context context) {
return PreferenceManager.getDefaultSharedPreferences(context).getInt(MORNING_MINUTE, 0);
}
public static void setMorningMinute(Context context, Integer morningMinute) {
PreferenceManager.getDefaultSharedPreferences(context).edit().putInt(MORNING_MINUTE, morningMinute).apply();
}
...,然后使用TimePicker对话框在我的应用程序设置中设置首选项
@Override
public void onTimeSet(RadialPickerLayout view, int hourOfDay, int minute, int second) {
Preferences.setMorningHour(getApplicationContext(), hourOfDay);
Preferences.setMorningMinute(getApplicationContext(), minute);
}
当启动Activity时,您需要检查警报是否已经存在。 如果生活不打扰。 参见下面的代码。
Intent myIntent = new Intent(MainActivity.this, MyReceiver.class);
boolean isWorking = (PendingIntent.getBroadcast(MainActivity.this, 0, myIntent, PendingIntent.FLAG_NO_CREATE) != null);
if (isWorking) {Log.d("alarm", "is working");} else {Log.d("alarm", "is not working");}
if(!isWorking) {
pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
int timeNotif = 5 * 60 * 1000;//time in ms, 7*24*60*60*1000 for 1 week
Log.d("Notif", "Notification every (ms): " + timeNotif);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), timeNotif, pendingIntent);
}
