如何在通知中显示数据库中的数据？

Question

我想在通知时显示特定事件的数据。喜欢事件标题，开始时间，结束时间和位置。

我已创建通知，但我不知道如何将此数据发送到通知中。

我在getAllEvents类中创建了EventTableHelper方法并从中检索数据。

这是我尝试创建通知并获取数据的方式。如何在通知中添加此数据？如何自定义此通知？

public class NotificationReceiver  extends BroadcastReceiver {


    private static final int MY_NOTIFICATION_ID = 0;
    NotificationManager notificationManager;
    Notification myNotification;

    EventTableHelper db;

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


        Toast.makeText(context, "Time is set", Toast.LENGTH_LONG).show();

        db = new EventTableHelper(context);

        List<EventData> testSavings = db.getAllEvents();

        for (EventData ts : testSavings) {
            String log = "from date:" + ts.getFromDate()
                    + " ,to date: " + ts.getToDate()
                    + " ,location: " + ts.getLocation()
                    + " ,title " + ts.getTitle();

            Date date = new Date();
            Date date1 = new Date();
            Log.d("Result: ", log);
            SimpleDateFormat df = new SimpleDateFormat("E MMM dd HH:mm:ss zzzz yyyy");
            SimpleDateFormat df2 = new SimpleDateFormat("HH:mm a");
            try {
                date = df.parse(ts.getFromDate());
                date1 = df.parse(ts.getToDate());
            } catch (ParseException ex) {

            }
            String timeFrom = df2.format(date);
            String startTime = String.valueOf(date);

            String timeTo = df2.format(date1);
            String endTime = String.valueOf(date1);


            String location = ts.getLocation();
            String title = ts.getTitle();

            Intent myIntent = new Intent(context, MainActivity.class);
            PendingIntent pendingIntent = PendingIntent.getActivity(
                    context,
                    0,
                    myIntent,
                    PendingIntent.FLAG_UPDATE_CURRENT);


            myNotification = new NotificationCompat.Builder(context)
                    .setContentTitle("Event")
                    .setContentText("Time")
                    .setWhen(System.currentTimeMillis())
                    .setContentIntent(pendingIntent)
                    .setAutoCancel(true)
                    .setSmallIcon(R.drawable.ic_alarm_black_48dp)
                    .build();


            Log.i("Notify", "Notification");
            notificationManager =
                    (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
            notificationManager.notify(MY_NOTIFICATION_ID, myNotification);

        }
    }
}

谢谢..
