TTS和播放声音 - Android

Question

我的应用程序中有一个viewpager.当用户向右/向左滑动时,我使用TTS引擎说出文本,使用MediaPlayer播放声音.

问题是同时播放..一旦TTS引擎说话文本结束,我该如何播放声音？

PS:我不想睡觉或等待.

更新:

这是我的代码:

@SuppressLint("NewApi")
@SuppressWarnings("deprecation")
@Override
public void onInit(int status) {
    if (status == TextToSpeech.SUCCESS) {

        if (result == TextToSpeech.LANG_MISSING_DATA
                || result == TextToSpeech.LANG_NOT_SUPPORTED) {
        } else {
            //Do Something here
        }


        if(Build.VERSION.SDK_INT  >= 15 ){
            UtteranceProgressListener listener = 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
                    //start MediaPlayer
                    playMedia(viewPager.getCurrentItem());
                }
            };
            tts.setOnUtteranceProgressListener(listener);
        }
        else{
            tts.setOnUtteranceCompletedListener(new OnUtteranceCompletedListener(){

                @Override
                public void onUtteranceCompleted(String arg0) {
                     playMedia(viewPager.getCurrentItem());
                }

              });
        }
    } else {
        Intent installIntent = new Intent();
        installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
        startActivity(installIntent);
    }
}

你必须给它一个id参数.否则它不会调用侦听器:

HashMap<String, String> params = new HashMap<String, String>();
params.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID,"stringId");

textToSpeech.speak(string,TextToSpeech.QUEUE_ADD, params);
