我正在制作一个应用程序,每次触发广播接收器时都使用tts来合成wav文件.我正在开发AndroidStudio(最新版)并使用最低15级的API级别19.

我有一个带有BroadcastListener的服务.每次执行BroadcastListener onReceive方法时,我都会使用

tts.synthesizeToFile(playing, null, storagePath + "/" + "tst.wav");

该文件已成功创建,但永远不会调用UtteranceProgressListener的onDone()方法.

public void onCreate() {
    super.onCreate();

    //Get TTS capabilities
    //TODO: Use TextToSpeech.Engine.ACTION_CHECK_TTS_DATA to check if tts is available
    tts = new TextToSpeech(PresenterService.this,
            new TextToSpeech.OnInitListener() {
                @Override
                public void onInit(int status) {

                    //If the TTS engine was started successfully

                    if (status != TextToSpeech.ERROR) {

                        tts.setLanguage(Locale.US);
                        tts.setPitch(PRESENTER_PITCH);
                        tts.setSpeechRate(PRESENTER_RATE);
                    }

                }
            });

    tts.setOnUtteranceProgressListener(new TtsUtteranceListener());



    IntentFilter filter = new IntentFilter();
    filter.addAction("xxxxxxxxxxxxxxxxxx");

    mReceiver = new TrackChangedReceiver(tts);
    registerReceiver(mReceiver, filter);

}

和TtsUtteranceListener类:

public class TtsUtteranceListener extends UtteranceProgressListener …
