我想在特定时间发送通知。以下是我的代码。现在,我只在启动应用程序时收到通知,但是我没有在指定时间收到通知。你能帮我理解我做错了吗?

 NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle("My notification")
            .setContentText("Trainieren sie jetzt!")
            .setAutoCancel(true);
    Intent resultIntent = new Intent(this, MainActivity2.class);

    AlarmManager alarmManager =(AlarmManager)getSystemService(ALARM_SERVICE);



    PendingIntent resultPendingIntent =
        PendingIntent.getActivity(
        this,
        0,
        resultIntent,
        PendingIntent.FLAG_UPDATE_CURRENT);


   Calendar cal = Calendar.getInstance();
   cal.set(Calendar.HOUR_OF_DAY, 12);
   cal.set(Calendar.MINUTE, 54);
   alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 24*60*60*1000, resultPendingIntent);



    mBuilder.setContentIntent(resultPendingIntent);
    int mNotificationId = 001;
    NotificationManager mNotifyMgr = 
            (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    mNotifyMgr.notify(mNotificationId, mBuilder.build());

感谢您的帮助!

您需要添加:

@Override
public void onReceive(Context context, Intent intent) {
    //  Toast.makeText(MainActivity.con, "Hello from alarm", 1).show(); 


    // System.out.println("Hello from Alarm");
    context.startService(new Intent(context, NotificationService.class));

}

在上面的示例中,我将流程定向到我的Service类来处理我的通知,管理唤醒锁定和后台服务实现。如果您没有实现服务,则可以在onRecieve方法中显示通知。

请查看here它是否完整实现了警报类。
