TextToSpeech 서비스가 시작되지 않았습니다.

Question

TextTo 음성 작동하지 않습니다. 서비스가 시작되지 않았으며 google play.it에서 음성 텍스트를 설치했음을 보여줍니다. 버튼으로 연결되었을 때 올바르게 작동했지만 onCreate에서 이동할 때 작동하지 않습니다. (가) .IT 바운드 TTS 엔진 successfulu 및 표시 텍스트 길이

Answer 1

먼저 당신의 else 잘못된 장소에, 그것은 두 번째로 첫 번째 if

ttsobj=new TextToSpeech(getApplicationContext(),new TextToSpeech.OnInitListener() { 

    @Override 
    public void onInit(int status) { 
     // TODO Auto-generated method stub 
     if(status==TextToSpeech.SUCCESS) 
     { 
      int result=ttsobj.setLanguage(Locale.US); 
      if(result==TextToSpeech.LANG_MISSING_DATA || result==TextToSpeech.LANG_NOT_SUPPORTED) 
      { 
       Log.e("TTS","This Language is Not supported"); 
       Intent installation=new Intent(); 
       installation.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA); 
       startActivity(installation); 
      } 

     } 
     else{ 
       Log.e("TTS","Installation Failed"); 
      } 
    } 
    }); 

와 일치해야합니다, 당신은 speak를 호출 할 수 없습니다 유엔 까지 onInit이 호출됩니다.
