在通过文本到语音说话然后恢复时暂停手机铃声(Pause Phone Ringtone while Speaking through Text To Speech and then Resume)

 我正在制作一个使用TTS说出来电者姓名的来电者。 我想在TTS讲话时暂停铃声然后恢复铃声。 根据我的研究，我们可以使用AudioFocus （希望如此）。 无论如何，我使用以下代码 
 
 更新 
 
 我现在正在使用此代码。 
 
public void speak(final String talk) throws InterruptedException {
     final AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
     int musicVolume= audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
     audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, musicVolume, 0);
     audioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);

    int result = tts.setOnUtteranceProgressListener(new UtteranceProgressListener() {

        @Override
        public void onStart(String utteranceId) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onError(String utteranceId) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onDone(String utteranceId) {
            // TODO Auto-generated method stub
            audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
            System.out.println("done");
        }
    });
    HashMap<String, String> params = new HashMap<String, String>();
    params.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID,"stringId");
    tts.speak(talk, TextToSpeech.QUEUE_FLUSH, params);
    System.out.println("speaking after tts is over" + talk+" "+result);

}
 
 虽然Ringtone已停止并且播放了tts ，但播放tts后Ringtone未恢复。 我该怎么办？ 

I am making a caller speaking application which speak caller name using TTS. I want to pause the ringtone while TTS is speaking then resuming the ringtone. From what i have researched we can use AudioFocus (hope so). Anyway i am using the following code 
 
Update
 
I am using this code now. 
 
public void speak(final String talk) throws InterruptedException {
     final AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
     int musicVolume= audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
     audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, musicVolume, 0);
     audioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);

    int result = tts.setOnUtteranceProgressListener(new UtteranceProgressListener() {

        @Override
        public void onStart(String utteranceId) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onError(String utteranceId) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onDone(String utteranceId) {
            // TODO Auto-generated method stub
            audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
            System.out.println("done");
        }
    });
    HashMap<String, String> params = new HashMap<String, String>();
    params.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID,"stringId");
    tts.speak(talk, TextToSpeech.QUEUE_FLUSH, params);
    System.out.println("speaking after tts is over" + talk+" "+result);

}
 
Although the Ringtone is stopped and tts is played but after tts is played Ringtone is not resumed. What should i do?
