Question

我正在尝试使用AlarmManager推送通知，这是我的代码：

package notification;

import android.app.AlarmManager;
import android.app.Notification;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.graphics.drawable.BitmapDrawable;
import android.media.RingtoneManager;
import android.os.Build;

import com.example.hoang.bnhnint.R;
import com.example.hoang.bnhnint.ViewScheduleActivity;

import java.util.Calendar;
import java.util.GregorianCalendar;

public class NotificationUtils {
private Context context;
private static int INDEX = 1;

public NotificationUtils(Context context) {
    this.context = context;
}

public void scheduleNotification(int hour_of_day, int minute, int notificationId) {//delay is after how much time(in millis) from current time you want to schedule the notification
    Notification.Builder builder = new Notification.Builder(context)
            .setContentTitle("Tới giờ uống thuốc buổi sáng")
            .setContentText("Tới giờ uống thuốc buổi sáng")
            .setAutoCancel(true)
            .setSmallIcon(R.drawable.pill)
            .setLargeIcon(((BitmapDrawable) context.getResources().getDrawable(R.drawable.pill)).getBitmap())
            .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));

    Intent intent = new Intent(context, ViewScheduleActivity.class);
    PendingIntent activity = PendingIntent.getActivity(context, notificationId, intent, PendingIntent.FLAG_CANCEL_CURRENT);
    builder.setContentIntent(activity);
    Notification notification;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
        notification = builder.build();
    } else {
        notification = builder.getNotification();
    }
    Intent notificationIntent = new Intent(context, NotificationPublisher.class);
    notificationIntent.putExtra(NotificationPublisher.NOTIFICATION_ID, notificationId);
    notificationIntent.putExtra(NotificationPublisher.NOTIFICATION, notification);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, notificationId, notificationIntent, PendingIntent.FLAG_CANCEL_CURRENT);

    Calendar cal = new GregorianCalendar();
    cal.set(Calendar.HOUR_OF_DAY, hour_of_day);
    cal.set(Calendar.MINUTE, minute);
    AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);
}

}

这是我的发布者：

package notification;

import android.app.Notification;
import android.app.NotificationManager;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class NotificationPublisher extends BroadcastReceiver {
public static String NOTIFICATION_ID = "notification_id";
public static String NOTIFICATION = "notification";

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

    NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

    Notification notification = intent.getParcelableExtra(NOTIFICATION);
    int notificationId = intent.getIntExtra(NOTIFICATION_ID, 0);
    notificationManager.notify(notificationId, notification);
}
}

我在这里称呼它

   TimePickerDialog timePickerDialog = new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {
        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
            NotificationUtils utils = new NotificationUtils(SetMedicineTakingTimeActivity.this);
            utils.scheduleNotification(hourOfDay, minute, 1);
        }
    }, hour, minute, true);

经过大量研究后，我得出了这些代码。但这是行不通的。我试图每天在特定时间从TimePickerDialog推送通知。此外，任何人都可以解释通知ID真正做什么？
