android - 我想在 8 :00 am everyday 显示通知

我正在尝试使用警报管理器在特定时间(每天上午 8:00)向用户发送通知。
但我的代码不正确，请帮助我获取显示通知

我的主要 Activity

  @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    AlarmController al=new AlarmController(this);
    al.StartAlarm();

}

我的报警 Controller

  public class AlarmController {

    private Context m_Context;
    private AlarmManager mgr;
    private static final long PERIOD = 1000 * 30;

    public AlarmController(Context context){

        m_Context = context;
        mgr = (AlarmManager)m_Context.getSystemService(Context.ALARM_SERVICE);
    }

    public void StartAlarm(){



        Intent i = new Intent(m_Context, OnAlarmReceiver.class);
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        calendar.set(Calendar.HOUR_OF_DAY,8);

        PendingIntent pi=PendingIntent.getBroadcast(m_Context, 0,i, PendingIntent.FLAG_UPDATE_CURRENT);
        mgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
                AlarmManager.INTERVAL_DAY, pi);



        Log.i("AlarmController", "StartAlarm");
    }

    public void StopAlarm(){
        Intent i = new Intent(m_Context, OnAlarmReceiver.class);
        PendingIntent pi=PendingIntent.getBroadcast(m_Context, 0,i, PendingIntent.FLAG_UPDATE_CURRENT);
        mgr.cancel(pi);

        Log.i("AlarmController", "StopAlarm");
    }
}

和 OnAlarmReceiver

public class OnAlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
context.startService(new Intent(context, AppService.class));

}
}

AppService

 public int onStartCommand(Intent intent, int flags, int startId) {
    Log.i(TAG, "start job");

    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentTitle("My notification")
                    .setContentText("از اپ سرویس!");

    int mNotificationId = 001;
    NotificationManager mNotifyMgr =
            (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

    mNotifyMgr.notify(mNotificationId, mBuilder.build());
    Log.i(TAG, "stop job");
    return START_STICKY;
}

最佳答案

alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmIntent = new Intent(context of current file, AlarmReceiver1.class);

    pendingIntent = PendingIntent.getBroadcast(Menu.this, 0, alarmIntent,PendingIntent.FLAG_UPDATE_CURRENT);
    alarmIntent.setData((Uri.parse("custom://"+System.currentTimeMillis())));
    alarmManager.cancel(pendingIntent);

    Calendar alarmStartTime = Calendar.getInstance();
    Calendar now = Calendar.getInstance();
    alarmStartTime.set(Calendar.HOUR_OF_DAY, 8);
    alarmStartTime.set(Calendar.MINUTE, 00);
    alarmStartTime.set(Calendar.SECOND, 0);
    if (now.after(alarmStartTime)) {
        Log.d("Hey","Added a day");
        alarmStartTime.add(Calendar.DATE, 1);
    }

     alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, alarmStartTime.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
     Log.d("Alarm","Alarms set for everyday 8 am.");

来到广播接收器类。您需要在 list 中注册您的广播接收器。这将导致您接收时钟事件。
覆盖此广播接收器的 onReceive 方法并在那里发出通知，或者创建一个单独的通知构建服务并在那里构建和显示您的通知。

list 代码 fragment :

<receiver android:name="AlarmReceiver1"  android:enabled="true">

广播接收器代码 fragment :

public class AlarmReceiver1 extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
      Intent service1 = new Intent(context, NotificationService1.class);
  service1.setData((Uri.parse("custom://"+System.currentTimeMillis())));
              context.startService(service1);
}

通知构建服务代码 fragment :

public class NotificationService1 extends IntentService{

    private NotificationManager notificationManager;
    private PendingIntent pendingIntent;
    private static int NOTIFICATION_ID = 1;
    Notification notification;
@Override
    protected void onHandleIntent(Intent intent) {
ontext context = this.getApplicationContext();
           notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
 Intent mIntent = new Intent(this, Activity to be opened after clicking on the notif);
            Bundle bundle = new Bundle();
            bundle.putString("test", "test");
            mIntent.putExtras(bundle);
            pendingIntent = PendingIntent.getActivity(context, 0, mIntent, PendingIntent.FLAG_UPDATE_CURRENT);

            Resources res = this.getResources();
            NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
            Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);
            notification = new NotificationCompat.Builder(this)
                        .setContentIntent(pendingIntent)
                        .setSmallIcon(R.drawable.ic_launcher)
                        .setLargeIcon(BitmapFactory.decodeResource(res, R.drawable.ic_launcher))
                        .setTicker("ticker value")
                        .setAutoCancel(true)
                        .setPriority(8)
                        .setSound(soundUri)
                        .setContentTitle("Notif title")
                        .setContentText("Text").build();
            notification.flags |= Notification.FLAG_AUTO_CANCEL | Notification.FLAG_SHOW_LIGHTS;
            notification.defaults |= Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE;
            notification.ledARGB = 0xFFFFA500;
            notification.ledOnMS = 800;
            notification.ledOffMS = 1000;
            notificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
            notificationManager.notify(NOTIFICATION_ID, notification);
            Log.i("notif","Notifications sent.");

    }

}
