Reconnaissance vocale Android NPE

Question

J'ai un problème dans mon application Android. Le problème est que la reconnaissance vocale ne fonctionne pas quand elle atteint la méthode startActivityForResult (intention, int), elle montre que je dois ajouter Bundle. La reconnaissance de la parole est ajoutée dans une classe qui est appelée à l'intérieur de la classe Adaper et non dans MainActivity comme le font les personnes.

Voici le code pour la reconnaissance vocale

public class SpeechRecog extends Activity { 

    private static final int VOICE_RECOGNITION_REQUEST_CODE = 1001; 
    ArrayList<String> thingsYouSaid = new ArrayList<String>(); 

    public void Start(Intent i, Context c) { 
     i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); 
     i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US"); 
     i.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1); 
     i.putExtra(RecognizerIntent.EXTRA_PROMPT, "Are You Done , yet? "); 
     //try{ 
     startActivityForResult(i, VOICE_RECOGNITION_REQUEST_CODE); 
     //}catch(Exception e){ 
     //Toast.makeText(c, "SpeechRecogntion is not avalible on your device ", Toast.LENGTH_LONG).show(); 

     //} 

    } 


    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     if ((requestCode == 
       VOICE_RECOGNITION_REQUEST_CODE) && (resultCode == RESULT_OK)) { 

      thingsYouSaid = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS); 
      if (checkResult()) 
       Toast.makeText(getApplicationContext(), 
         "You are done ", Toast.LENGTH_LONG).show(); 
      else 
       Toast.makeText(getApplicationContext(), 
         "You are not done ", Toast.LENGTH_LONG).show(); 

     } 

     super.onActivityResult(requestCode, resultCode, data); 
    } 


    public boolean checkResult() { 

     for (int i = 0; i < thingsYouSaid.size(); i++) { 

      if ((thingsYouSaid.get(i).equals("done")) 
        || (thingsYouSaid.get(i).equals("yes"))) 
       return true; 

     } 
     //if (textResult.equals("done")||(textResult.equals("yes"))) 
     //return true ; 

     return false; 
    } 

} 

Ici, le OnclickListenre intérieur classe adaptateur

Lh.btn.setOnClickListener(new OnClickListener() { 
    @Override 
    public void onClick(View v) { 

     String[] items = db.GetItemArray(Lh.text); 
     String[] itemFlags = db.GetItemsFlagsArray(Lh.text); 
     //final itemHolder ihc = new itemHolder(); 

     if (Lh.btn.getText().equals("read")) { 
      Lh.btn.setText("Pause"); 
      int i; 
      for (i = 0; i < items.length; i++) { 

       if (Integer.valueOf(itemFlags[i]) == 1) { 

        continue; 
       } 

       int timeofitem = Integer.parseInt(db.getItemTime(items[i])); 
       //Toast.makeText(context, items[i] , Toast.LENGTH_SHORT).show(); 
       TTS.Talk(items[i], 1); 
       TTS.Scilence(timeofitem); 

       SpeechRecog SP = new SpeechRecog(); 
       SP.Start(new Intent(), context); 

       // checking items 
       ItemsFields itemToBeChanged = new ItemsFields(Lh.text, items[i], 0, timeofitem); 
       itemToBeChanged.setFlag(1); 
       db.updateItems(itemToBeChanged); 

       //ihc.checkbox.setChecked(true); 
      } 

      TTS.Talk("Congrats ,Your Checklist is Completed ", 1); 


     } else { 
      Lh.btn.setText("read"); 
      TTS.Talk("The Checklist is paused , Press again if you want to continue , Bye", 0); 
      return; 

     } 
    } 

});

* {@link IntentSender#sendIntent IntentSender.sendIntent} on it. 
* 
* @param intent  The IntentSender to launch. 
* @param requestCode If >= 0, this code will be returned in 
*      onActivityResult() when the activity exits.

Answer 1

jamais instancier activités avec new. Utilisez un Intent pour lancer de nouvelles activités ou utiliser une activité existante instanciée par le cadre pour onActivityResult().

Pour ce dernier, remplacer

SpeechRecog SP = new SpeechRecog(); 
SP.Start(new Intent(), context); 

avec le code de Start() (à savoir la mise en place d'un Intent et d'appeler startActivityForResult() et tirer onActivityResult() à cette activité.
