java - 发生点击时 RecognizerIntent.ACTION_RECOGNIZE_SPEECH 被阻止

Question

在我的主要 Activity 中，我启动了一个新的 Intent:

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);

然后我检索这里所说的关键字:

@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);
    }

现在一切正常，但我注意到一个问题。在 RecognizerIntent.ACTION_RECOGNIZE_SPEECH.. 如果我点击谷歌眼镜(以任何方式在 D-pad 上)，它会错误地识别语音。这意味着它拒绝检测任何声音。是什么导致了这个问题？

当我点击方向键时，在 SPEECH_REQUEST 期间我遇到了两个主要错误:

更新:

我注意到，一旦我为 RecognizerIntent.ACTION_RECOGNIZE_SPEECH 设置了错误，最终将检测到连续向下滑动几次，然后我返回到新的 RecognizerIntent.ACTION_RECOGNIZE_SPEECH，或者它完全离开应用程序。我将在未来几天发布更多相关信息。

如果您仍然遇到问题，请尝试以下操作:

在最顶层，声明一个私有(private)的GestureDetector:

private GestureDetector gestureDetector;

然后，在 onCreate() 方法中，调用创建 GestureDetector 的方法(没有理由只在 code>onCreate() 方法 - 这样看起来更干净并且更有条理):

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;
}

您必须确保在末尾包含 onGenericMotionEvent() 方法。这就是确保每次发生运动事件时通知您的 GestureDetector 的原因。

我添加的内容非常微小，但非常重要 - 通过将 onSingleTapUp() 方法的返回值更改为 true，您是在告诉 Glass事件被正确处理(在这种情况下，只是什么都不做)。
