Android的實施RecognitionListener

Question

當作爲this answer by Iftah說我可以從意圖越來越開放的由語音Recoginition android系統中記錄的聲音傳遞給獲得意圖：

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    // the recording url is in getData: 
    Uri audioUri = data.getData(); 
} 

這裏Intent data有什麼我想要沒有問題。

這一切都完美的作品，但是這種解決方案提出了一個提示的時候說話的用戶，我不想這樣，所以要解決這個問題，我讓我的活動實施RecognitionListener像這樣：

public class MainActivity extends AppCompatActivity implements RecognitionListener { 

    private SpeechRecognizer speech = null; 
    private Intent recognizerIntent; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     recognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); 
     recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "sv_SE"); 
     recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, "sv_SE"); 
     recognizerIntent.putExtra("android.speech.extra.GET_AUDIO_FORMAT", "audio/AMR"); 
     recognizerIntent.putExtra("android.speech.extra.GET_AUDIO", true); 

     speech = SpeechRecognizer.createSpeechRecognizer(this); 
     speech.setRecognitionListener(this); 
     speech.startListening(recognizerIntent); 
    } 

    @Override 
    public void onReadyForSpeech(Bundle params) { 
     Log.d("Debug", "On ready for speech"); 
    } 

    @Override 
    public void onBeginningOfSpeech() { 
     Log.d("Debug", "On beggining of speech"); 
    } 

    @Override 
    public void onRmsChanged(float rmsdB) { 
     Log.d("Debug", "Rsm changed"); 
    } 

    @Override 
    public void onBufferReceived(byte[] buffer) { 
     Log.d("Debug", "Buffer recieved"); 
    } 

    @Override 
    public void onEndOfSpeech() { 
     Log.d("Debug", "On end of speech"); 
    } 

    @Override 
    public void onError(int error) { 
     Log.d("Debug", "Error"); 
    } 

    @Override 
    public void onPartialResults(Bundle partialResults) { 
     Log.d("Debug", "On partial result"); 
    } 

    @Override 
    public void onEvent(int eventType, Bundle params) { 
     Log.d("Debug", "On event"); 
    } 

    @Override 
    public void onResults(Bundle results) { 
     Log.d("Debug", "On result"); 
    } 
} 

這得到各地提示hovewer我無法弄清楚如何獲得烏里像在第一個例子，因爲這裏：

@Override 
    public void onResults(Bundle results) { 
     Log.d("Debug", "On result"); 
     // The results bundle don't contain the URI! 
    } 

我得到一個Bundle results不包含的意圖或URI。我嘗試過查看捆綁包中的所有密鑰，並且沒有URI或Intent存在，我也試過getIntent()但是不返回任何內容。

我感謝任何幫助或推動正確的方向。

結果應與關鍵字SpeechRecognizer.RESULTS_RECOGNITION捆綁在一起。

@Override 
public void onResults(Bundle results) { 
    if (results != null && results.containsKey(SpeechRecognizer.RESULTS_RECOGNITION)) { 
     List<String> resultsList = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION); 
     // most likely result is resultsList.get(0) 
    } else { 
     // no results 
    } 

} 

請參閱SpeechRecognizer的Android開發者文檔詳細解釋它。這種獲取語音識別結果的方法也適用於部分結果#onPartialResults
