我正在构建一个应用程序，它会在11:30 IST触发通知。我已经测试了它的工作但是在11:30之后每当我打开我的应用程序时它会发出通知......
我不知道为什么我认为在时间检查条件下应该是一些错误......
我希望通知只能在一天中按时触发一次......然后是第二天...... :)
请解决此问题 提前谢谢

经过大量的茶和咖啡，我自己编写了答案...
long t = System.currentTimeMillis();
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 11);
calendar.set(Calendar.MINUTE, 30);
calendar.set(Calendar.SECOND, 00);
if (t <= calendar.getTimeInMillis()) {
//calendar.add(Calendar.DATE, 6); //add 6 days.
Intent intent1 = new Intent(MainActivity.this, AlarmReciever.class);
intent1.setAction("NOTE");
PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, intent1, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager am = (AlarmManager) MainActivity.this.getSystemService(MainActivity.this.ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
//am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
}
else{
}
我刚刚将系统时间与通知时间进行了比较..如果通知时间小于等于系统时间，则其真实和接收器将起作用..但如果没有，那么什么都不会发生......
BTW感谢您帮助@tiny和@Mahesh

为了防止警报在每次启动应用程序时持续触发（在警报时间过后），可以添加以下内容：
Calendar timeNow = Calendar.getInstance();
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 11);
calendar.set(Calendar.MINUTE, 30);
if(calendar.before(timeNow)){
calendar.add(Calendar.DATE, 1);
}
mAlarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, mAlarmPendingIntent);
我找到了上面的例子here。现在将根据闹钟时间检查时间，如果闹钟时间在现在时间之前，则会在闹钟中添加另一天。 希望这有助于:)。

我也有这个问题＆amp;尝试了这个页面上的每一个建议，我无法解决我的问题。以下是针对此问题的建议解决方案，它适用于我。
在manifest.xml中注册接收器
<receiver android:name=".receivers.DayAlarmReceiver"/>
设置闹钟管理器
public void setDayAlarm(Context context) {
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 4);
AlarmManager alarmMgr = (AlarmManager) getSystemService(ALARM_SERVICE);
Intent alarmIntent = new Intent(context, DayAlarmReceiver.class);
alarmIntent.putExtra("HOUR_OF_DAY", 4);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 5555, alarmIntent, 0);
alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY, pendingIntent);
Log.d("Set the day alarm");
}
检查接收者类的onReceive（）方法中的意图附加内容
@Override
public void onReceive(Context context, Intent intent) {
int setHour = intent.getIntExtra("HOUR_OF_DAY", -1);
Calendar rightNow = Calendar.getInstance();
int currentHour = rightNow.get(Calendar.HOUR_OF_DAY);
if(currentHour == setHour){
Log.d("This is perfect, Trigger the alarm");
showNotification(context, msg);
}else{
Log.d("This is perfect, Trigger the alarm");
}
