[英]speech recognition in android not working
我正在尝试创建一个应用程序,当电话打来时,呼叫必须根据用户语音命令自动出席或结束。 在这里我给了我尝试的东西,我在startVoiceRecognitionActivity()方法中遇到错误,例如Activity找不到异常:找不到活动来处理意图。
public void startVoiceRecognitionActivity()
{
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Voice recognition Demo...");
startActivityForResult(intent, REQUEST_CODE);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
if (requestCode == REQUEST_CODE && resultCode == RESULT_OK)
{
String spch = data.getStringExtra(RecognizerIntent.EXTRA_RESULTS);
if (spch.contains("Yes"))
{
enableSpeakerPhone(this);
Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON);
KeyEvent event = new KeyEvent(KeyEvent.ACTION_DOWN,KeyEvent.KEYCODE_HEADSETHOOK);
i.putExtra(Intent.EXTRA_KEY_EVENT, event );
this.sendOrderedBroadcast(i, null);
}
else if(spch.contains("No"))
{
Intent buttonUp = new Intent(Intent.ACTION_MEDIA_BUTTON);
buttonUp.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HEADSETHOOK));
this.sendOrderedBroadcast(buttonUp, "android.permission.CALL_PRIVILEGED");
}
}
super.onActivityResult(requestCode, resultCode, data);
}
谁能帮我找出问题所在...
您是否在清单文件中正确声明了活动?
