如何在演讲结束后关闭通知

Question

如何在语音运行时保持通知？

主要活动：

TextToSpeech tts;

...

public void notification () {
NotificationCompat.Builder notification = 
new NotificationCompat.Builder(this) 
.setSmallIcon(R.drawable.ic_volume_up_white_36dp)
.setOngoing(true)
NotificationManager NotifyMgr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
NotifyMgr.notify(1, notification.build());
}

...

public void speak() {
    tts=new TextToSpeech(getApplicationContext(),new TextToSpeech.OnInitListener() {
        @Override
        public void onInit(int status) {
            notification(); //Call Notification
            tts.setLanguage(Locale.US);
            tts.speak("message", TextToSpeech.QUEUE_FLUSH, null);
        }
    });
}

执行通知取消操作所需的内容以及应在何处输入通知

NotifyMgr.cancel(1);

Answer 1

使用isSpeaking方法检查tts是否在说话。

if(!isSpeaking()){
notifymgr.cancel(1);
}

Answer 2

这对我有用。

public void speakNotification() {
    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            NotificationManager NotifyMgr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
            if (tts.isSpeaking()) {
                NotifyMgr.notify(3, notificationSpeak.build());
            } else {
                speakNotification();
            }
            if(!tts.isSpeaking()) {
                NotifyMgr.cancel(3);
            } else {
                speakNotification();
            }
        }
    }, 1); //1 is the update time
}

public void speakMotd() {
    tts=new TextToSpeech(getApplicationContext(),new TextToSpeech.OnInitListener() {
        @Override
        public void onInit(int status) {
            speakNotification();
            tts.setLanguage(Locale.US);
            tts.speak("message", TextToSpeech.QUEUE_FLUSH, null);
        }
    });
}

因为应用程序停止工作，所以需要新的处理程序。
