java - 无法显示生日提醒

Question

我的应用程序包含一个 SQLite 数据库来存储个人信息。我将生日存储为长值。我想在保存的列表中如果有人今天过生日，则显示通知。我正在检索长生日值，将其设置为日历并将其与当前日历月份和日期进行比较。但问题是，如果某人的生日与当前日期匹配，则会出现通知，但显示这是列表中最后一个人的生日，无论最后一个人的生日是什么。请帮忙。提前致谢。

这是代码

calendar_now = Calendar.getInstance();
    calendar_now.setTimeInMillis(System.currentTimeMillis());
    int month_now = calendar_now.get(Calendar.MONTH);
    int day_now = calendar_now.get(Calendar.DAY_OF_MONTH);

    //Set a specific time to the calendar
    calendar_now.set(Calendar.HOUR_OF_DAY, 6);
    calendar_now.set(Calendar.MINUTE, 0);
    calendar_now.set(Calendar.SECOND, 0);

    dbHelper = new DbHelper(this);
    personArrayList = dbHelper.getPerson();

    birth_calendar = Calendar.getInstance();

    for (Person p : personArrayList) {

        name = p.getName(); //Get the person's name
        mobile = p.getMobile();
        byte_image = p.getByteImage();
        position = personArrayList.indexOf(p);
        DoB = p.getDateOfBirth();
        birth_calendar.setTimeInMillis(DoB);
        int birth_month = birth_calendar.get(Calendar.MONTH);
        int birthday = birth_calendar.get(Calendar.DAY_OF_MONTH);

        if ((birth_month == month_now) && (birthday == day_now)) {

            Intent intent = new Intent(this, NotificationReceiver.class);

            PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 100, intent,
                    PendingIntent.FLAG_UPDATE_CURRENT);

            AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
            alarmManager.setExact(AlarmManager.RTC_WAKEUP, calendar_now.getTimeInMillis(), pendingIntent);
        } else {
            Toast.makeText(this, "No birthday today", Toast.LENGTH_SHORT).show();
        }

        birth_calendar.clear();

    }

NotificationReceiver.java

public class NotificationReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    NotificationManager notificationManager = (NotificationManager)
            context.getSystemService(Context.NOTIFICATION_SERVICE);

    //Open PersonDetailsActivity on notification click
    Intent resultIntent = new Intent(context, PersonDetailsActivity.class);
    //Pass the values through intent to PersonDetailsActivity
    resultIntent.putExtra("name", MainActivity.name);
    resultIntent.putExtra("mobile", MainActivity.mobile);
    resultIntent.putExtra("DoB", MainActivity.DoB);
    resultIntent.putExtra("image", MainActivity.byte_image);
    resultIntent.putExtra("position", MainActivity.position);

    resultIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent pendingIntent = PendingIntent.getActivity(context, 100,
            resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder mBuilder = (NotificationCompat.Builder)
            new NotificationCompat.Builder(context)
                    .setContentIntent(pendingIntent)
                    .setSmallIcon(R.drawable.ic_notification)
                    .setContentTitle("Birthday reminder")
                    .setContentText("It is " +MainActivity.name+ "'s birthday today, " +
                            "wish him/her \"Happy birthday!!\"")
                    .setVibrate(new long[]{250, 250, 250, 250})
                    .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
                    .setAutoCancel(true);

    notificationManager.notify(100, mBuilder.build());
}

}

if ((birth_month == month_now) && (birthday == day_now)) {

            Intent intent = new Intent(this, NotificationReceiver.class);
            Intent intent = new Intent(context , DocumentSubFolder.class);
            intent.putExtra("name" , name);
            intent.putExtra("mobile" , mobile);
            intent.putExtra("Dob" , DoB);
            intent.putExtra("image" , byte_image);
            intent.putExtra("position" , position);

            PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 100, intent,
                    PendingIntent.FLAG_UPDATE_CURRENT);

            AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
            alarmManager.setExact(AlarmManager.RTC_WAKEUP, calendar_now.getTimeInMillis(), pendingIntent);
        } 

NotificationReceiver.java

resultIntent.putExtra("name", intent.getStringExtra("name));
    resultIntent.putExtra("mobile", intent.getStringExtra("mobile));
    resultIntent.putExtra("DoB", intent.getStringExtra("Dob));
    resultIntent.putExtra("image", intent.getStringExtra("image));
    resultIntent.putExtra("position", intent.getStringExtra("position));

用此替换您的代码。
