通过文本转语音朗读时暂停电话铃声，然后恢复

我正在制作一个来电者语音应用程序，它使用 TTS 说出来电者姓名。我想在 TTS 说话时暂停铃声，然后恢复铃声。根据我的研究，我们可以使用AudioFocus（希望如此）。 无论如何我正在使用以下代码

Update

我现在正在使用这段代码。

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被停止并且tts已播放但之后tts玩过的Ringtone没有恢复。我应该怎么办？

终于在折腾了两天之后我终于做到了。对于所有想要实现类似的东西但无法这样做的人，这里是代码

public void speak(final String talk) throws InterruptedException {
    final AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
    int ringVolume = audioManager
            .getStreamVolume(AudioManager.STREAM_RING);
    int musicVolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
    currentRingVolume = ringVolume;

    musicVolume = (int) ((musicVolume * seekbarValue) / 100);

    if (PauseRingtone == true) {
        audioManager.setStreamVolume(AudioManager.STREAM_RING, 1,
                AudioManager.FLAG_SHOW_UI);
    } else {
        audioManager.setStreamVolume(AudioManager.STREAM_RING,
                ringVolume, AudioManager.FLAG_SHOW_UI);
    }

    audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, musicVolume, 0);

    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
                    System.out.println("done");
                    audioManager.setStreamVolume(AudioManager.STREAM_RING,
                            currentRingVolume, 0);
                }
            });
    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);

}

解释 ：-

ringVolume- 获取当前音量ringtone.即手机中设置的铃声音量。

musicVolume- 获取当前音量music

currentRingVolume只是保留了ringVolume.

Note- STREAM_RING and STREAM_MUSIC are different things. See

现在的基本想法是mute the ringtone while TTS正在说话，然后将其设置为先前的值。

seekBarValue- is my SeekBar它描绘了的水平TTS体积 w.r.tmusicVolume并且是可选的。

PauseRingtone- is a CheckBox Preference它检查我们是否要在说话时暂停铃声。如果true是设置AudioManager.STREAM_RING to 1 i.e. vibrate else ringVolume i.e. Phone Value，所以两者TTS and Ringtone同时玩。

audioManager.setStreamVolume(AudioManager.STREAM_MUSIC,musicVolume, 0) 

设置音量TTS to musicVolume. After TTS已完成讲话，即在onDone()我们设置音量Ringtone回到ringVolume using currentRingVolume.
