Java 除按钮事件（如onClick）外，正常调用时语音识别器不工作
我的程序中有语音识别器，当我直接在onCreate方法中运行startListening方法时，语音识别器似乎不工作。 但是，当我在button-onClick方法中加入startListening方法时，语音识别器就开始工作了。我希望语音识别器方法startListening直接调用，如下面的程序所示 下面是我的节目Java 除按钮事件（如onClick）外，正常调用时语音识别器不工作,java,android,speech-recognition,Java,Android,Speech Recognition,我的程序中有语音识别器，当我直接在onCreate方法中运行startListening方法时，语音识别器似乎不工作。 但是，当我在button-onClick方法中加入startListening方法时，语音识别器就开始工作了。我希望语音识别器方法startListening直接调用，如下面的程序所示 下面是我的节目 SpeechRecognizer mSpeechRecognizer; Intent mSpeechRecognizerIntent; TextView textV

请告诉我解决方案。我刚刚在createSpeechRecognizer之后设置了used SetRecognizationListener，代码正在运行
public void Listen(View view) {
mSpeechRecognizer.startListening(mSpeechRecognizerIntent);
}
mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
mSpeechRecognizer.setRecognitionListener(recognitionListener);
mSpeechRecognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE,
Locale.getDefault());
mSpeechRecognizer.startListening(mSpeechRecognizerIntent);
