Question

我在Android中创建了一个与此code类似的NotificationListenerService。我的应用程序在单独的窗口中显示通知。什么时候用户在我的窗口中单击通知，相应的应用程序将被打开。

public void onNotificationPosted(StatusBarNotification sbn) {

        Bundle extras = sbn.getNotification().extras;
        String title = getStringFromBundle(extras, "android.title");
        String subText = getStringFromBundle(extras, "android.subText");
        String text = getStringFromBundle(extras, "android.text");
        String bigText = getStringFromBundle(extras, "android.bigText");
        String array[] = { title, subText, text, bigText };
        int progress = extras.getInt("android.progress", 0);
        int progressMax = extras.getInt("android.progressMax", 0);
        int int_array[] = { progress, progressMax };
        notification_added(sbn, array, int_array, bitmap); //Adds the notification in a list
}

我尝试使用密钥打开通知。

public void OpenNotification(String key) {
        String keys[] = { key };
        StatusBarNotification sbns[] = getActiveNotifications(keys);
        for (StatusBarNotification sbn : sbns) {
                try {
                        if (sbn == null) {
                                Log.i(TAG, "sbn is null");
                                continue;
                        }
                        /*
                           Notification n = sbn.getNotification();
                           if (n.contentIntent != null) {
                           PendingIntent pi = n.contentIntent;
                           if (pi != null) {
                           pi.send(this, 0, null);
                           }
                           }
                         */
                        cancelNotification(key);
                        Intent intent = getPackageManager().getLaunchIntentForPackage(
                                        sbn.getPackageName());
                        if (intent != null) {
                                Log.i(TAG, "Launching intent " + intent + " package name: "
                                                + sbn.getPackageName());
                        }
                } catch (Exception e) {
                }
        }
}

例如，如果点击了电子邮件通知，则应用会启动电子邮件应用。但是，它不会打开确切的电子邮件活动。如何从StatusBarNotification对象中打开活动。

Answer 1

将 YOURACTIVITY 替换为您要点击通知时要打开的活动

    Intent intent = new Intent(getBaseContext(), YOURACTIVITY.class);
    PendingIntent contentIntent = PendingIntent.getActivity(getBaseContext(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder b = new NotificationCompat.Builder(getBaseContext());

    b.setAutoCancel(true)
            .setDefaults(Notification.DEFAULT_ALL)
            .setWhen(System.currentTimeMillis())
            .setSmallIcon(R.drawable.ic_launcher)
            .setTicker("Ticker") 
            .setContentTitle("title") 
            .setContentText("message") 
            .setDefaults(Notification.DEFAULT_LIGHTS | Notification.DEFAULT_SOUND)
            .setContentIntent(contentIntent)
            .setContentInfo("Info"); 

    Random r = new Random();
    int randomNo = r.nextInt(100000000 + 1);

    NotificationManager notificationManager = (NotificationManager) getBaseContext().getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(randomNo, b.build());
