Question

我希望这并不违反任何规则，因为我已尝试按照“如何询问”指南进行操作。

我尝试使用NotificationListenerService读取传入的通知，它对我有用但只是部分。

它的类型的第一个通知，让我们说 - whatsapp我可以获得自动收报机，文本和标题，但是如果通知叠加我我再也无法阅读邮件的文本。

如何获取叠加通知的文字？

以下是我目前正在实施的代码：

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+，WhatsApp会使用MessageStyle Expanded Notifications。在这里 - https://developer.android.com/training/notify-user/expanded.html#message-style

从

等通知中检索所有5条消息

这样做：

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*/

            }
        }
    }

我不知道我是否想念你，但是我已经将一个代码堆叠起来并逐一显示在logcat上，只有我遇到的问题就是当我收到这个问题时第一条消息，我在logcat上的文本显示为null，在第一条消息之后，所有传入的消息都在工作。

        extras = sbn.getNotification().extras;
