在特定时间推送多个通知(AlarmManager、NotificationManager) -安卓

Question

我正在尝试制作离线推送通知，将在特定的时间推送一次。以下是我的日历和AlarmManager设置：

Intent intent = new Intent(getApplicationContext(), Notification_receiver.class);

    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

    PendingIntent pendingIntent1 = PendingIntent.getBroadcast(getApplicationContext(), 101, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    PendingIntent pendingIntent2 = PendingIntent.getBroadcast(getApplicationContext(), 102, intent, PendingIntent.FLAG_UPDATE_CURRENT);


    Calendar push1 = Calendar.getInstance();
    Calendar push2 = Calendar.getInstance();

    push1.set(2017, Calendar.JULY, 1);
    push1.set(Calendar.HOUR_OF_DAY, 20);
    push1.set(Calendar.MINUTE, 22);
    push1.set(Calendar.SECOND, 30);

    push2.set(2017, Calendar.JULY, 1);
    push2.set(Calendar.HOUR_OF_DAY, 20);
    push2.set(Calendar.MINUTE, 28);
    push2.set(Calendar.SECOND, 30);


    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, push1.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent1);
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, push2.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent2);

和我的通知类：

public class Notification_receiver extends BroadcastReceiver{


@Override
public void onReceive(Context context, Intent intent) {

    NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

    Intent repeating_intent = new Intent(context, RepeatingActivity.class);
    repeating_intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent pendingIntent1 = PendingIntent.getActivity(context, 101, repeating_intent, PendingIntent.FLAG_UPDATE_CURRENT);
    PendingIntent pendingIntent2 = PendingIntent.getActivity(context, 102, repeating_intent, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder builder1 = new NotificationCompat.Builder(context).setContentIntent(pendingIntent1)
            .setSmallIcon(R.drawable.onusicijadi_icon)
            .setContentTitle("FIRST")
            .setContentText("FIRST NOTIFICATION")
            .setDefaults(Notification.DEFAULT_ALL)
            .setAutoCancel(true);

    notificationManager.notify(103, builder1.build());

    NotificationCompat.Builder builder2 = new NotificationCompat.Builder(context).setContentIntent(pendingIntent2)
            .setSmallIcon(R.drawable.onusicijadi_icon)
            .setContentTitle("SECOND")
            .setContentText("SECOND NOTIFICATION")
            .setDefaults(Notification.DEFAULT_ALL)
            .setAutoCancel(true);

    notificationManager.notify(104, builder2.build());

}}

RepeatingActivity.class只是：

public class RepeatingActivity extends AppCompatActivity{


@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

     setContentView(R.layout.activity_program);

}

这段代码在20:22和20:28发送两个通知，很明显，我希望将它们分开。例如，一个通知在20:22开始，另一个在20:28开始。我需要大约30个通知，为每个事件在3天的节日。

您使用的是哪种api？

注意:从API 19开始，所有重复告警都是不准确的。

使用这些服务时要小心，如果您在短时间内收到多个通知，您可以考虑使用服务。
