全志行车记录仪里面FireEyepublic.apk反编译的分析（三）——TTS语音播报_全志 tts

接（一）的分析：FireEyeTTS.init(getResources());

  public static void init(Resources paramResources)
  {
    FIRE_EYE_START = paramResources.getString(2131165307);
    RECORD_MODE_VALUE_TWO = paramResources.getString(2131165308);
    RECORD_MODE_VALUE_FRONT = paramResources.getString(2131165309);
    RECORD_MODE_VALUE_BACK = paramResources.getString(2131165310);
    START_RECORDING = paramResources.getString(2131165311);
    STOP_RECORDING = paramResources.getString(2131165312);
    ………………
  }

没有必要多解析，就是初始化需要播报的字符串资源。

  private void initTTS()
  {
    if (mConfig.getTextToSpeech())
       FireEyeTTS.StartUseTTS();
    else
	FireEyeTTS.StopUseTTS();	
 
    if (FireEyeTTS.mTTS == null)
      FireEyeTTS.mTTS = new TextToSpeech(this, this);
 
  }

TTS的初始化。这个好像是android系统自带的。

在FireEye.java中：

  public void onInit(int paramInt)
  {
    if (paramInt == 0)
    {
      FireEyeTTS.mTTS.setLanguage(Locale.CHINESE);
      Log.d(TAG, "oninit start_record_default = " + start_record_default);
      if (start_record_default)
        startFireEyeTTS();
    }
 
      if (paramInt != -1)
      		Toast.makeText(this, "Error occurred while initializing Text-To-Speech engine", 1).show();
 
  }

  private void startFireEyeTTS()
  {
    if (mConfig.getAppErrorExit())
    {
      FireEyeTTS.speakChinese(FireEyeTTS.UN_CAUGHT_EXCEPTION);
      mConfig.setAppErrorExit(false);
    }
//如果app error就播放 程序异常，退出

    if (CarReversingFlag != -1)
        FireEyeTTS.speakChinese(FireEyeTTS.CAR_REVERSING);  //倒车播报
	
      FireEyeTTS.speakChineseAfterStop(FireEyeTTS.FIRE_EYE_START);

      if (mConfig.getMotionDetect())
        FireEyeTTS.speakChineseAfterStop(FireEyeTTS.MOTION_DETECT_OPEN); //移动侦测功能打开
	  
      if (getIntent().getIntExtra("is_first", 1) != 1)
      		ShowStorageStatus();//第一次进入的时候要判断内存卡的状态
	  
      if ((!mConfig.getAutoRecording()) || ((mConfig.mMotionStatus == 1) && (mConfig.getWorkStatus() == 0)) || (!mExternalStorage))
      		FireEyeTTS.speakChineseAfterStop(FireEyeTTS.AUTO_RECORDING);//判断是否自动录像
      mHandler.sendEmptyMessage(9);
    
  }

转到FireTTS.java:

  public static void speakChinese(String paramString)
  {
    if (!isUsingTTS){
	 if (mTTS != null){
		mTTS.speak(paramString, TextToSpeech.QUEUE_FLUSH, null);
	 }	
    }
  }

  public static void speakChineseAfterStop(String paramString)
  {
    if (!isUsingTTS){
		if (mTTS != null){
  			mTTS.speak(paramString, TextToSpeech.QUEUE_ADD, null);
		}
    }
  }

每个独立的TTS实例管理语音消息列队请求的优先级和顺序等。当引用 “ TextToSpeech.QUEUE_FLUSH ” 调用Speak（）方法时，会中断当前实例正在运行的任务（也可以理解为清除当前语音任务，转而执行新的列队任务）。引用 “ TextToSpeech.QUEUE_ADD ”标签的发音任务将被添加到当前任务列队之后。
