TTS (Text To Speech) in Fragments

I want to implement TTS function in fragment in my app, but failed due to not enough understanding between Activity and Fragment.

But found some sources in stackoverflow.com! (Link:http://stackoverflow.com/questions/16866173/text-to-speech-in-fragment)

However, I failed over and over again.. and found the cause..  It was "return view" code in onInit.

Anyhow, finally I succeeded, below is my source. 

Fragment.java

public class Q01Fragment extends Fragment implements View.OnClickListener, TextToSpeech.OnInitListener {     private TextToSpeech txts;     private static final String TAG = "TextToSpeechDemo";     private static final int MY_DATA_CHECK_CODE = 1234;     private TextToSpeech tts;     //private Button btnSpeak;     //private EditText txtText;     public static Q01Fragment newInstance() {         Q01Fragment fragment = new Q01Fragment();         return fragment;     }     public Q01Fragment() {         // Required empty public constructor     }     @Override     public View onCreateView(LayoutInflater inflater, ViewGroup container,                              Bundle savedInstanceState) {         View view = inflater.inflate(R.layout.fragment_q01, container, false);         Button button = (Button) view.findViewById(R.id.button_Q01);         button.setOnClickListener(this);         txts = new TextToSpeech(getActivity(), this);         // Fire off an intent to check if a TTS engine is installed         Intent checkIntent = new Intent();         checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);         startActivityForResult(checkIntent, MY_DATA_CHECK_CODE);         return view;     }     @Override     public void onDestroy() {         // Don't forget to shutdown!         if (txts != null) {             txts.stop();             txts.shutdown();         }         super.onDestroy();     }     private void speakOut() {         String text = "This is New code";         txts.speak(text, TextToSpeech.QUEUE_FLUSH, null);     }          @Override     public void onClick(View v) {         switch (v.getId()) {             case R.id.button_Q01:                 //Toast.makeText(getActivity(), "One Fragment", Toast.LENGTH_SHORT).show();                 speakOut();                 break;         }     }     @Override     public void onInit(int status) {         if (status == TextToSpeech.SUCCESS) {             int result = txts.setLanguage(Locale.US);             if (result == TextToSpeech.LANG_MISSING_DATA                     || result == TextToSpeech.LANG_NOT_SUPPORTED) {                 Log.e("TTS", "Language is not supported");             } else {             }         } else {             Log.e("TTS", "Initilization Failed");         }     } }
