BroadcastReceiver 呼叫服务只循环一次

Question

下面是我的 tts 服务代码：

public class SMSTTSService extends Service implements TextToSpeech.OnInitListener, OnUtteranceCompletedListener {
private TextToSpeech tts;
private String spokenText;
@Override
public void onCreate() {
    tts = new TextToSpeech(this, this);     
}
@Override
public void onInit(int status) {        
    if (status == TextToSpeech.SUCCESS) {
        int result = tts.setLanguage(Locale.ENGLISH);
        // tts.setPitch(5); // set pitch level
        // tts.setSpeechRate(2); // set speech speed rate
        if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {
            Log.e("TTS", "Language is not supported");
        } else {                
            speakOut(spokenText);
        }

        /*if (result != TextToSpeech.LANG_MISSING_DATA && result != TextToSpeech.LANG_NOT_SUPPORTED) {
            tts.speak(c, TextToSpeech.QUEUE_FLUSH, null);
        }*/
    } else {
        Log.e("TTS", "Initilization Failed");
    }
}
private void speakOut(String text) {
    tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
}
@Override
public void onUtteranceCompleted(String uttId) {
    stopSelf();
}
@Override
public void onDestroy() {
    if (tts != null) {
        tts.stop();
        tts.shutdown();
    }
    super.onDestroy();
}
@Override
public IBinder onBind(Intent intent) {
    return null;
}       
@Override
public void onStart(Intent intent, int startId) {
    super.onStart(intent, startId);     
    spokenText = intent.getStringExtra("spoken_txt");
}
}

从接收器中调用服务器：

public class Receiver extends BroadcastReceiver {
    private static final String TAG = "SMSReceiver";
    @Override
    public void onReceive(Context context, Intent intent) {
for(int i=0; i<msgs.length; i++) {
....
 Intent intentTTS = new Intent(context, SMSTTSService.class);
                        intentTTS.putExtra("spoken_txt", msgBody);
                        context.startService(intentTTS);
}

但是在循环语句中服务器只执行一次。这是哪的问题？如何避免?

Answer 1

先检查下msgs.length长度
长度没问题，改成这样行不行
@Override
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);

spokenText = intent.getStringExtra("spoken_txt");

//do your method
speakOut(spokenText);
}
