如何在android中显示多个通知 [英] How to display multiple notifications in android

问题描述

我只收到一个通知，如果有另一个通知，它会替换上一个通知，这是我的代码

I am receiving only one notification and if there comes another notification, it replaces the previous one and here is my code

private static void generateNotification(Context context, String message,
        String key) {
    int icon = R.drawable.ic_launcher;
    long when = System.currentTimeMillis();
    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(icon, message, when);

    String title = context.getString(R.string.app_name);

    Intent notificationIntent = new Intent(context,
            FragmentOpenActivity.class);
    notificationIntent.putExtra(key, key);
    // set intent so it does not start a new activity
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
            | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    PendingIntent intent = PendingIntent.getActivity(context, 0,
            notificationIntent, 0);
    notification.setLatestEventInfo(context, title, message, intent);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;

    notification.defaults |= Notification.DEFAULT_SOUND;

    // notification.sound = Uri.parse("android.resource://" +
    // context.getPackageName() + "your_sound_file_name.mp3");
    notification.defaults |= Notification.DEFAULT_VIBRATE;
    notificationManager.notify(0, notification);

}

我的问题是这样解决的...

I solved my problem like this...

/**
     * Issues a notification to inform the user that server has sent a message.
     */
    private static void generateNotification(Context context, String message,
            String keys, String msgId, String branchId) {
        int icon = R.drawable.ic_launcher;
        long when = System.currentTimeMillis();
        NotificationCompat.Builder nBuilder;
        Uri alarmSound = RingtoneManager
                .getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        nBuilder = new NotificationCompat.Builder(context)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("Smart Share - " + keys)
                .setLights(Color.BLUE, 500, 500).setContentText(message)
                .setAutoCancel(true).setTicker("Notification from smartshare")
                .setVibrate(new long[] { 100, 250, 100, 250, 100, 250 })
                .setSound(alarmSound);
        String consumerid = null;
        Integer position = null;
        Intent resultIntent = null;
        if (consumerid != null) {
            if (msgId != null && !msgId.equalsIgnoreCase("")) {
                if (key != null && key.equalsIgnoreCase("Yo! Matter")) {
                    ViewYoDataBase db_yo = new ViewYoDataBase(context);
                    position = db_yo.getPosition(msgId);
                    if (position != null) {
                        resultIntent = new Intent(context,
                                YoDetailActivity.class);
                        resultIntent.putExtra("id", Integer.parseInt(msgId));
                        resultIntent.putExtra("position", position);
                        resultIntent.putExtra("notRefresh", "notRefresh");
                    } else {
                        resultIntent = new Intent(context,
                                FragmentChangeActivity.class);
                        resultIntent.putExtra(key, key);
                    }
                } else if (key != null && key.equalsIgnoreCase("Message")) {
                    resultIntent = new Intent(context,
                            FragmentChangeActivity.class);
                    resultIntent.putExtra(key, key);
                }.

        } else {
            resultIntent = new Intent(context, MainLoginSignUpActivity.class);
        }
        PendingIntent resultPendingIntent = PendingIntent.getActivity(context,
                notify_no, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        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());
    }
