如何在Android中暂停和恢复SpeechRecognizer？

Question

我正在使用SpeechRecognizer类。

这是我的代码：

SpeechRecognizer     speechRecognizer;
speechRecognizer = SpeechRecognizer.createSpeechRecognizer(getBaseContext());
MyRecognitionListener speechListner=new MyRecognitionListener();
speechRecognizer.setRecognitionListener(speechListner);
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getApplication().getPackageName());
speechRecognizer.startListening(intent);

问题是我无法暂停并恢复它。我已经尝试过了：

speechRecognizer.cancel();
speechRecognizer.stopListening();

但它仍在倾听。

Answer 1

您不能将stopListening（）调用到已取消的SpeechRecognizer。在取消（）之前调用它。

speechRecognizer.stopListening();
speechRecognizer.cancel();
