每次我打开应用程序时都会触发预定通知

Question

我正在构建一个在 11:30 IST 触发通知的应用程序..我已经测试了它的工作但是在 11:30 每当我打开我的应用程序时它都会发出通知...

我不知道为什么我认为它应该是在时间检查中出现了一些错误...

我希望每天只按时触发一次通知...然后在第二天...:)

请解决这个问题提前致谢

**MainActivity.java**

Answer 1

Intent intent1 = new Intent(MainActivity.this, AlarmReciever.class);
intent1 .setAction("ilove");


public void onReceive(Context context, Intent intent) {
 if(!"ilove" .equalsIgnoreCase(getAction()))log.e("test",intent.getAction());
}


<receiver android:name="com.android.app.AlaramReceiver" android:exported="false">
 <intent-filter>
<action android:name="ilove" /> 
</intent-filter>
</receiver>

Answer 2

喝了这么多茶和咖啡后，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，则它为真，接收者将工作。但如果不是，则什么都不会发生...

顺便说一句，感谢您帮助@tiny 和@Mahesh

calendar 日历 = Calendar.getInstance();

          calendar.set(Calendar.HOUR, 6);

    int myPreferedTime=calendar.get(Calendar.HOUR);


    Calendar rightNow = Calendar.getInstance();

    int currentHour = rightNow.get(Calendar.HOUR_OF_DAY);
    Log.i("current time","is"+currentHour);


    int difference=myPreferedTime-currentHour;

    Log.i("Differencevalue","is"+difference);

    switch(difference)
    {
        case 1:

Answer 4

为防止每次启动App时（超过闹钟时间后）Alarm不断触发，可以添加：

    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。现在的时间根据闹钟时间进行检查，如果闹钟时间早于现在的时间，则将另一天添加到闹钟中。希望这会有所帮助 :)。

Answer 5

我也遇到了这个问题，虽然尝试了此页面上的所有建议，但我无法解决我的问题。这是针对此问题的建议解决方案，它适用于我。

在manifest.xml

中注册接收者

<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");
}

在接收方的 onReceive() 方法中检查 intent extras class

@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");
 }

每次我打开应用程序时都会触发预定通知
