Question

我需要在用户选择通知开始的日期和时间时发出通知。为此，我将日期，时间和注释存储在数据库中。现在，我想使用数据库中的数据启动警报，并使用每个警报的ID作为PendingIntent的唯一ID。

这是我从数据库中获取数据的方式

db=new events_database(events_main.this);
    c=db.queryData("select * from events_list ORDER BY event_ID ASC");
    if(c != null && c.moveToNext())
    {
        int id=c.getInt(0);
        String type=c.getString(1);
        String date=c.getString(2);
        String time=c.getString(3);
        String note=c.getString(4);

        String[] newDate=date.split("/");
        int year=Integer.valueOf(newDate[0]);
        int month=Integer.valueOf(newDate[1]);
        int day=Integer.valueOf(newDate[2]);

        String[] newTime=time.split(":");
        int hour=Integer.valueOf(newTime[0]);
        int min=Integer.valueOf(newTime[1]);

        Alarms(id,year,month,day,hour,min,type,note);

    }

获取后我将数据传递给Alarms方法

public void Alarms(int id, int year, int month, int day, int hour, int minute, String type, String note) {
        Calendar calendar1 = Calendar.getInstance();
        calendar1.set(Calendar.YEAR,year);
        calendar1.set(Calendar.MONTH,month);
        calendar1.set(Calendar.DAY_OF_MONTH,day);
        calendar1.set(Calendar.HOUR_OF_DAY, hour);
        calendar1.set(Calendar.MINUTE, minute);
        calendar1.set(Calendar.MILLISECOND, 0);
        if (calendar1.before(Calendar.getInstance())) {
            calendar1.add(Calendar.DATE, 1);
        }
        Intent intent = new Intent(events_main.this, events_receiver.class);
        intent.putExtra("type",type);
        intent.putExtra("note",note);
        intent.putExtra("id",   id);
        PendingIntent dog1 = PendingIntent.getBroadcast(this, id, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        final AlarmManager alarm1 = (AlarmManager) getSystemService(ALARM_SERVICE);
        alarm1.setExact(AlarmManager.RTC_WAKEUP, calendar1.getTimeInMillis(), dog1);
        Toast.makeText(events_main.this, "alarms",Toast.LENGTH_SHORT).show();
}

然后在接收器

public class events_receiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        int id= Integer.valueOf(intent.getStringExtra("id"));
        String note=intent.getStringExtra("note");
        String type=intent.getStringExtra("type");

        NotificationManager notificationManager2=(NotificationManager)context.getSystemService(context.NOTIFICATION_SERVICE);
        Intent dog_intent2=new Intent(context,HomeActivity.class);
        dog_intent2.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent dog_pending2=PendingIntent.getActivity(context, id,dog_intent2, PendingIntent.FLAG_ONE_SHOT);;
        NotificationCompat.Builder builder2=new NotificationCompat.Builder(context)
                .setContentIntent(dog_pending2)
                .setSmallIcon(R.drawable.ic_action_prof_breed_icon)
                .setSound(Uri.parse("android.resource://" +context.getPackageName()+ "/" + R.raw.dog))
                .setContentTitle("Pet Guide 101")
                .setContentText(type)
                .setContentText(note)
                .setVibrate(new long[] { 1000, 1000})
                .setAutoCancel(true);
        notificationManager2.notify(id,builder2.build());
    }
}

但由于某种原因，警报不会被触发。当我测试代码时，我确实从数据库中获取数据，但警报仍未执行。如果你能查一查，请告诉我，如果我做错了，特别是将唯一身份证传递给接收者。

报警通知无法使用来自sqlite数据库的数据
