java - 广播接收器仅响应一天

问题描述

我想每天收到 namaz 时间的通知。假设 5 wakth namaj 通知。因此，我制作了一个应用程序并使用广播接收器在后台工作，并在确切时间到达时向我发送通知。我的应用程序在一天内运行良好。过了一天后，它不再向我发送通知。我在这里附上我的代码

Calendar c1 = Calendar.getInstance();
    Calendar c2 = Calendar.getInstance();
    Calendar c3 = Calendar.getInstance();
    Calendar c4 = Calendar.getInstance();
    Calendar c5 = Calendar.getInstance();
    Calendar c6 = Calendar.getInstance();
    c1.set(c1.get(Calendar.YEAR), c1.get(Calendar.MONTH), c1.get(Calendar.DAY_OF_MONTH), 4, 5, 0);
    c2.set(c2.get(Calendar.YEAR), c2.get(Calendar.MONTH), c2.get(Calendar.DAY_OF_MONTH), 5, 30, 0);
    c3.set(c3.get(Calendar.YEAR), c3.get(Calendar.MONTH), c3.get(Calendar.DAY_OF_MONTH), 12, 21, 0);
    c4.set(c4.get(Calendar.YEAR), c4.get(Calendar.MONTH), c4.get(Calendar.DAY_OF_MONTH), 16, 10, 0);
    c5.set(c5.get(Calendar.YEAR), c5.get(Calendar.MONTH), c5.get(Calendar.DAY_OF_MONTH), 17, 30, 0);
    c6.set(c6.get(Calendar.YEAR), c6.get(Calendar.MONTH), c6.get(Calendar.DAY_OF_MONTH), 19, 10, 0);
    setAlarm(c1.getTimeInMillis(), "Tahajjud");
    setAlarm(c2.getTimeInMillis(), "Fojor");
    setAlarm(c3.getTimeInMillis(), "Juhur");
    setAlarm(c4.getTimeInMillis(), "Asor");
    setAlarm(c5.getTimeInMillis(), "Magrib");
    setAlarm(c6.getTimeInMillis(), "Esha");

我的 setAlarm 方法是

    String namajText = namaj;
    AlarmManager alarmManager =(AlarmManager) getSystemService(Context.ALARM_SERVICE);

    Intent intent = new Intent(BackgroundNotificationOnTime.this,MyAlarm2.class);

    intent.putExtra("Namaj", namajText);

    PendingIntent pendingIntent = PendingIntent.getBroadcast(this,count,intent,PendingIntent.FLAG_ONE_SHOT);

    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,timeInMillis,AlarmManager.INTERVAL_DAY,pendingIntent);

    count++;

那是我的 onReceive 方法

String namajText = intent.getStringExtra("Namaj");
    int nId = 0;
    NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle("Namaj Alert")
            .setContentText(namajText+" namaj wakth started.")
            .setAutoCancel(true)
            .setDefaults(NotificationCompat.DEFAULT_ALL);

    Uri path = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    builder.setSound(path);

    NotificationManager notificationManager = (NotificationManager) context.getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(nId,builder.build());

解决方案

你用PendingIntent.FLAG_ONE_SHOT你的PendingIntent，这就是为什么每个警报只触发一次。因此，您需要使用另一个值来重复警报，例如 0。

从文档中PendingIntent.FLAG_ONE_SHOT：

指示此 PendingIntent 只能使用一次的标志。用于 getActivity(Context, int, Intent, int)、getBroadcast(Context, int, Intent, int) 和 getService(Context, int, Intent, int)。

如果设置，则在调用 send() 后，它将自动为您取消，并且将来通过它发送的任何尝试都将失败。
