接收多个通知并在android中删除通知

Question

在我的项目中，我正在处理通知。 我已成功收到多个通知，其注册ID很好。 我的问题是，当我使用具有相同注册ID的删除通知时，它在通知栏上仅显示一个通知。 我想在通知栏上显示所有通知，如果我选择一个通知，则必须将其从通知栏中删除。 请告诉我任何解决方案mycode：

RegIdDTO.java：

public class RegIdDTO {
    public static final int REG_ID= (int) Calendar.getInstance().getTimeInMillis();
}

intentservice.java：

public class GcmIntentService extends IntentService{
    Context context;

    //System.currentTimeMillis();

    private NotificationManager mNotificationManager;
    NotificationCompat.Builder builder;
    public static final String TAG = "GCM Demo";

    public GcmIntentService() {
        super("GcmIntentService");
        // TODO Auto-generated constructor stub
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        // TODO Auto-generated method stub
        Bundle extras = intent.getExtras();
        String msg = intent.getStringExtra("message");
        GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
        String messageType = gcm.getMessageType(intent);


         if (!extras.isEmpty()) {

             if (GoogleCloudMessaging.
                        MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
                    sendNotification(RegIdDTO.REG_ID,"Send error: " + extras.toString());
                } else if (GoogleCloudMessaging.
                        MESSAGE_TYPE_DELETED.equals(messageType)) {
                    sendNotification(RegIdDTO.REG_ID,"Deleted messages on server: " +
                            extras.toString());
                // If it's a regular GCM message, do some work.
                } else if (GoogleCloudMessaging.
                        MESSAGE_TYPE_MESSAGE.equals(messageType)) {
                    // This loop represents the service doing some work.
                    for (int i=0; i<5; i++) {
                        Log.i(TAG, "Working... " + (i+1)
                                + "/5 @ " + SystemClock.elapsedRealtime());
                        try {
                            Thread.sleep(500);
                        } catch (InterruptedException e) {
                        }
                    }
                    Log.i(TAG, "Completed work @ " + SystemClock.elapsedRealtime());
                    // Post notification of received message.
                    //sendNotification("Received: " + extras.toString());
                    sendNotification(RegIdDTO.REG_ID,msg);
                    Log.i(TAG, "Received: " + extras.toString());
                }
            }

        myintent.putExtra("message", msg);
        myintent.setData(Uri.parse("content://"+when));

        PendingIntent contentIntent = PendingIntent.getActivity(this, 1,

        Notification notification=mBuilder.build();


        AudioManager am = (AudioManager)this.getSystemService(Context.AUDIO_SERVICE);

        /* Even if the mode is set to "Sound & Vibration" in the phone, 
         * the status code that getRingerMode() returns is RINGER_MODE_NORMAL.

        }

    public void CancelNotification(Context ctx) {

        NotificationManager nMgr = (NotificationManager) ctx
                .getSystemService(ns);
        nMgr.cancel(RegIdDTO.REG_ID);


    }
}

receiveactivity.java:

尝试这个

private static void sendNotification(Context context, String message,
            String keys, String msgId, String branchId) {
        NotificationCompat.Builder nBuilder;
        Uri alarmSound = RingtoneManager
                .getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        nBuilder = new NotificationCompat.Builder(context)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("header")
                .setLights(Color.BLUE, 500, 500).setContentText(message)
                .setAutoCancel(true).setTicker("Notification from s")
                .setVibrate(new long[] { 100, 250, 100, 250, 100, 250 })
                .setSound(alarmSound);
                // write your click event here
            Intent resultIntent = new Intent(context, MainLoginSignUpActivity.class);

    PendingIntent resultPendingIntent = PendingIntent.getActivity(context,
            notify_no, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
            // Show the max number of notifications here
    if (notify_no < 9) {
        notify_no = notify_no + 1;
    } else {
        notify_no = 0;
    }
    nBuilder.setContentIntent(resultPendingIntent);
    NotificationManager nNotifyMgr = (NotificationManager) context
            .getSystemService(context.NOTIFICATION_SERVICE);
    nNotifyMgr.notify(notify_no + 2, nBuilder.build());
}
