TextToSpeech in a服务

我在Service中遇到了TTS的问题。它的行为就像它想说话但它从来没有。看着它打印的“收到的TTS：它应该说的文本”LogCat，当它初始化时就会记录并显示成功。我试图为它创建一个线程，但没有帮助。 onUtteranceComplete从来没有触发过。我甚至做过这样的（只是用于测试）while循环：TextToSpeech in a服务

while(mTTS.isSpeaking()) { 
     Log.d("", "speaking"); 
}

...它从来没有说

我知道TTS设置正确，因为它的工作原理在常规Activity

这是我的代码。

import java.util.HashMap; 
import java.util.Locale; 

import android.app.Service; 
import android.content.Intent; 
import android.media.AudioManager; 
import android.os.IBinder; 
import android.speech.tts.TextToSpeech; 
import android.speech.tts.TextToSpeech.OnInitListener; 
import android.speech.tts.TextToSpeech.OnUtteranceCompletedListener; 
import android.util.Log; 

public class TTSService extends Service implements OnInitListener, OnUtteranceCompletedListener { 
TextToSpeech mTTS; 

    @Override 
    public void onCreate() { 
     Log.d("", "TTSService Created!"); 
     mTTS = new TextToSpeech(getApplicationContext(), this); 


     //I've tried it in a thread.... 
     /*new Thread(new Runnable() { 
      @Override 
      public void run() { 
       HashMap<String, String> myHashStream = new HashMap<String, String>(); 
       myHashStream.put(TextToSpeech.Engine.KEY_PARAM_STREAM, String.valueOf(AudioManager.STREAM_NOTIFICATION)); 
       myHashStream.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "1"); 

       mTTS.setLanguage(Locale.US); 
       //mTTS.setOnUtteranceCompletedListener(this); 
       mTTS.speak("I'm saying some stuff to you!", TextToSpeech.QUEUE_FLUSH, myHashStream);   
      } 

     }).start();*/ 

     //I've tried it not in a thread... 
     HashMap<String, String> myHashStream = new HashMap<String, String>(); 
     myHashStream.put(TextToSpeech.Engine.KEY_PARAM_STREAM, String.valueOf(AudioManager.STREAM_NOTIFICATION)); 
     myHashStream.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "1"); 

     mTTS.setLanguage(Locale.US); 
     mTTS.setOnUtteranceCompletedListener(this); 
     mTTS.speak("I'm saying some stuff to you!", TextToSpeech.QUEUE_FLUSH, myHashStream);  

    } 

    @Override 
    public IBinder onBind(Intent intent) { 

     return null; 
    } 

    @Override 
    public void onInit(int status) { 
     Log.d("", "TTSService onInit: " + String.valueOf(status)); 
     if(status == TextToSpeech.SUCCESS){ 
      Log.d("", "TTS Success"); 
     } 
    } 

    public void onUtteranceCompleted(String uttId) { 
     Log.d("", "done uttering"); 
     if(uttId == "1") { 
      mTTS.shutdown(); 
     } 

    } 

}

我没有得到这个工作。我现在将服务中的信息传递给我的活动，如果它处于活动状态。 – Ifor

...是的。我没有可以传递给它的活动。 – bwoogie

好吧，我知道了，现在想通了！在TTS初始化之前，它正在尝试说话。所以在一个线程中，我等待准备好不要== 999.一旦它或者1或者其他任何东西，我们都会照顾说话。这可能并不安全，但将其置于一段时间，但它仍在工作。

import java.util.HashMap; 
import java.util.Locale; 

import android.app.Service; 
import android.content.Intent; 
import android.media.AudioManager; 
import android.os.IBinder; 
import android.speech.tts.TextToSpeech; 
import android.speech.tts.TextToSpeech.OnInitListener; 
import android.speech.tts.TextToSpeech.OnUtteranceCompletedListener; 
import android.util.Log; 

public class TTSService extends Service implements OnInitListener, OnUtteranceCompletedListener { 
TextToSpeech mTTS; 
int ready = 999; 
    @Override 
    public void onCreate() { 

     Log.d("", "TTSService Created!"); 
     mTTS = new TextToSpeech(getApplicationContext(), this); 

     new Thread(new Runnable() { 
      @Override 
      public void run() { 
       while(ready == 999) { 
        //wait 
       } 
       if(ready==1){ 
       HashMap<String, String> myHashStream = new HashMap<String, String>(); 
       myHashStream.put(TextToSpeech.Engine.KEY_PARAM_STREAM, String.valueOf(AudioManager.STREAM_NOTIFICATION)); 
       myHashStream.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "1"); 

       mTTS.setLanguage(Locale.US); 
       //mTTS.setOnUtteranceCompletedListener(this); 
       mTTS.speak("I'm saying some stuff to you!", TextToSpeech.QUEUE_FLUSH, myHashStream); 

       } else { 
        Log.d("", "not ready"); 
        } 
      } 

     }).start(); 


     stopSelf(); 

    } 

    @Override 
    public IBinder onBind(Intent intent) { 

     return null; 
    } 

    @Override 
    public void onDestroy() { 
     mTTS.shutdown(); 
     super.onDestroy(); 
    } 
    @Override 
    public void onInit(int status) { 
     Log.d("", "TTSService onInit: " + String.valueOf(status)); 
     if (status == TextToSpeech.SUCCESS) 
     { 
      ready = 1; 

     } else { 
      ready = 0; 
      Log.d("", "failed to initialize"); 
     } 

    } 

    public void onUtteranceCompleted(String uttId) { 
     Log.d("", "done uttering"); 
     if(uttId == "1") { 
      mTTS.shutdown(); 
     } 

    } 


}

我刚刚也有类似的问题 - 它以mTTS.speak是由于TTS被onInit()开始前被调用。我解决它略有不同放置mTTS.speak()在一个单独的函数，然后调用该函数从onInit if (TextToSpeech.Successful)内，因此打讲话它发起并后不前（从onStart() ECT）。
