NotificationListenerService不读取堆叠通知的文本

Question

我希望这不会违反任何规则,因为我已经尝试过按照"如何询问"指南.

我正在尝试使用NotificationListenerService读取传入的通知,它对我有用但只是部分.

第一个通知它的类型,让我们说 - whatsapp我可以得到自动收报机,文本和标题,但如果通知叠加我不再能读取消息的文本.

如何获取堆叠通知的文本？

这是我目前实现的代码:

public class NotificationService extends NotificationListenerService {

    private Context context;


    @Override
    public void onCreate() {
        super.onCreate();
        context = getApplicationContext();

    }

    @Override
    public void onNotificationPosted(StatusBarNotification sbn) {
        String pack = sbn.getPackageName();
        String ticker = sbn.getNotification().tickerText.toString();
        Bundle extras = sbn.getNotification().extras;
        String title = "";
        String text = "";


        if (extras.containsKey("android.title")) {
            title = extras.getString("android.title");
        }

        if (extras.containsKey("android.text")) {
            if (extras.getCharSequence("android.text") != null) {
                text = extras.getCharSequence("android.text").toString();
            }
        }
        if (pack != null) {
            Log.i("Package", pack);
        }

        if (ticker != null) {
            Log.i("ticker", ticker);
        }

        if (title != null) {
            Log.i("Title", title);
        }

        if (text != null) {
            Log.i("Text", text);
        }


    }

    @Override
    public void onNotificationRemoved(StatusBarNotification sbn) {

    }


}

如果您使用的是Android 7.0+，则WhatsApp使用MessageStyle扩展通知。此处-https: //developer.android.com/training/notify-user/expanded.html#message-style

从通知中检索所有5条消息，例如

MyFriend (5 messages)
testt

做这个：

Bundle extras = mysbn.getNotification().extras;
if ((Build.VERSION.SDK_INT >= Build.VERSION_CODES.N)){
        Parcelable b[] = (Parcelable[]) extras.get(Notification.EXTRA_MESSAGES);

        if(b != null){
            content = "";
            for (Parcelable tmp : b){

                Bundle msgBundle = (Bundle) tmp;
                content = content + msgBundle.getString("text") + "\n";

                /*Set<String> io = msgBundle.keySet(); // To get the keys available for this bundle*/

            }
        }
    }

我不知道我是否误解了你，但我有一个代码可以将 Whatsapp 通知堆叠起来并在 logcat 上逐一显示，我遇到的唯一问题是当我收到第一条消息时，我的文本logcat 上显示为 null，在第一个消息之后，所有传入消息都正常工作。
