从广播接收器或服务启动Android TTS

Question

我想让TTS在后台运行.但是,我从来没有听到任何声音.我有一个广播接收器启动服务.我把我的TTS代码放在这两个代码中,但它从不说话.我知道正在调用该方法(我在其上设置了一个断点),但它仍然不起作用.

这是我的日志,但似乎没有包含有关TTS服务的任何内容.

提前谢谢大家!

有助于查看您的TTS代码,以便人们更轻松地为您提供帮助.由于我已经在BroadcastReceiver中使用了TTS,这里是一个从我的代码中删除的示例.

public static class TTS extends Service implements TextToSpeech.OnInitListener, OnUtteranceCompletedListener {
    private TextToSpeech mTts;
    private String spokenText;

    @Override
    public void onCreate() {
        mTts = new TextToSpeech(this, this);
        // This is a good place to set spokenText
    }

    @Override
    public void onInit(int status) {
        if (status == TextToSpeech.SUCCESS) {
            int result = mTts.setLanguage(Locale.US);
            if (result != TextToSpeech.LANG_MISSING_DATA && result != TextToSpeech.LANG_NOT_SUPPORTED) {
                mTts.speak(spokenText, TextToSpeech.QUEUE_FLUSH, null);
            }
        }
    }

    @Override
    public void onUtteranceCompleted(String uttId) {
        stopSelf();
    }

    @Override
    public void onDestroy() {
        if (mTts != null) {
            mTts.stop();
            mTts.shutdown();
        }
        super.onDestroy();
    }

    @Override
    public IBinder onBind(Intent arg0) {
        return null;
    }
}

在BroadcastReceiver中您希望它发言的位置启动TTS服务:

context.startService(new Intent(context, TTS.class));

如果不是提问者,我希望这可以帮助别人(我确信他现在已经开始工作了).
