Question

在我的主要活动中，我发布了一个新的意图：

Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "What would you like to find?\n For example \"Open heart surgery\"");
startActivityForResult(intent, SPEECH_REQUEST);

然后我检索这里说出的关键字：

@Override
protected void onActivityResult(int requestCode, int resultCode,
        Intent data) {
    if (requestCode == SPEECH_REQUEST && resultCode == RESULT_OK) {
        List<String> results = data.getStringArrayListExtra(
                RecognizerIntent.EXTRA_RESULTS);
        String spokenText = results.get(0);

            Intent intent = new Intent(ApiDemoActivity.this,SearchActivity.class);
            intent.putExtra("keyword", spokenText);
            startActivity(intent);
            finish();

    }
    super.onActivityResult(requestCode, resultCode, data);
    }

现在这一切都很好，但我发现了一个问题。在RecognizerIntent.ACTION_RECOGNIZE_SPEECH期间......如果我点击谷歌眼镜（以任何方式在D-pad上），它将会错误地识别语音。这意味着它拒绝检测任何声音。什么可能导致这个问题？

Logcat更新

当我点击Dpad时，我在SPEECH_REQUEST期间遇到两个主要错误：

12-08 10:12:58.687: E/SpeechRecognizer(940): not connected to the recognition service

12-08 10:12:58.695: E/GlassRecognitionService[41e733b8](940): VoiceService disconnected.

logcat的：

更新

我注意到，一旦我发现了RecognizerIntent.ACTION_RECOGNIZE_SPEECH，最终会检测到连续几次向下滑动并返回到新的RecognizerIntent.ACTION_RECOGNIZE_SPEECH，或者只是完全退出应用程序。我将在未来几天发布更多相关信息。

Answer 1

如果您仍然遇到问题，请尝试以下操作：

在最顶部，声明私有GestureDetector：

private GestureDetector gestureDetector;

然后，在onCreate()方法中，调用一个创建GestureDetector的方法（没有理由这样做而只是在onCreate()方法中创建它 - 它只是这样看起来更干净，更有条理）：

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ...
    gestureDetector = createGestureDetector(this);
}

createGestureDetector()方法如下所示：

private GestureDetector createGestureDetector(Context context) {
    GestureDetector gestureDetectorTemp = new GestureDetector(context, new GestureDetector.OnGestureListener() {
                        //we are creating our gesture detector here
        @Override
        public boolean onDown(MotionEvent motionEvent) {
            return false;
        }

        @Override
        public void onShowPress(MotionEvent motionEvent) {
        }

        @Override
        public boolean onSingleTapUp(MotionEvent motionEvent) {  //onTap
            return true; //<---this is the key
        }
        @Override
        public boolean onScroll(MotionEvent motionEvent, MotionEvent motionEvent2, float distanceX, float distanceY) {
            return false; //this is the wrong kind of scroll
        }
        @Override
        public void onLongPress(MotionEvent motionEvent) {
        }

        @Override
        public boolean onFling(MotionEvent motionEvent, MotionEvent motionEvent2, float v, float v2) { 
            return false;
        }
    });

    return gestureDetectorTemp;
}

@Override
public boolean onGenericMotionEvent(MotionEvent event) {
    if (gestureDetector != null) {
        return gestureDetector.onTouchEvent(event);
    }
    return false;
}

您必须确保在那里包含onGenericMotionEvent()方法。这就是确保每次发生运动事件时都会通知您GestureDetector的原因。

我添加的内容非常简单，但非常重要 - 通过将true方法上的返回值更改为onSingleTapUp()，您告诉Glass该事件已正确处理（在此处案例，只是无所事事。

您可以详细了解GestureDetector s here。

点击发生时，RecognizerIntent.ACTION_RECOGNIZE_SPEECH被阻止
