Android的实施RecognitionListener

Question

当作为this answer by Iftah说我可以从意图越来越开放的由语音Recoginition android系统中记录的声音传递给获得意图：

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

这里Intent data有什么我想要没有问题。

这一切都完美的作品，但是这种解决方案提出了一个提示的时候说话的用户，我不想这样，所以要解决这个问题，我让我的活动实施RecognitionListener像这样：

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"); 
    } 
} 

这得到各地提示hovewer我无法弄清楚如何获得乌里像在第一个例子，因为这里：

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

我得到一个Bundle results不包含的意图或URI。我尝试过查看捆绑包中的所有密钥，并且没有URI或Intent存在，我也试过getIntent()但是不返回任何内容。

我感谢任何帮助或推动正确的方向。

结果应与关键字SpeechRecognizer.RESULTS_RECOGNITION捆绑在一起。

@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 
    } 

} 

请参阅SpeechRecognizer的Android开发者文档详细解释它。这种获取语音识别结果的方法也适用于部分结果#onPartialResults
