Google glass 谷歌眼镜GDK点击手势

使用谷歌提供的GDK和示例代码，点击手势不会被识别为点击。只要每次按，就会返回。代码如下：

import com.google.android.glass.touchpad.Gesture;
import com.google.android.glass.touchpad.GestureDetector;

public class MainActivity extends Activity {

Logger log = Logger.getLogger("MainActivity");

private GestureDetector mGestureDetector;
// ...
@Override
protected void onCreate(Bundle savedInstanceState) {
    // ...
    mGestureDetector = createGestureDetector(this);
}

private GestureDetector createGestureDetector(Context context) {
GestureDetector gestureDetector = new GestureDetector(context);
    //Create a base listener for generic gestures
    gestureDetector.setBaseListener( new GestureDetector.BaseListener() {
        @Override
        public boolean onGesture(Gesture gesture) {
            log.info(gesture.name());
            if (gesture == Gesture.TAP) {
                // do something on tap
                return true;
            } else if (gesture == Gesture.TWO_TAP) {
                // do something on two finger tap
                return true;
            } else if (gesture == Gesture.SWIPE_RIGHT) {
                // do something on right (forward) swipe
                return true;
            } else if (gesture == Gesture.SWIPE_LEFT) {
                // do something on left (backwards) swipe
                return true;
            }
            return false;
        }
    });
    gestureDetector.setFingerListener(new GestureDetector.FingerListener() {
        @Override
        public void onFingerCountChanged(int previousCount, int currentCount) {
          // do something on finger count changes
        }
    });
    gestureDetector.setScrollListener(new GestureDetector.ScrollListener() {
        @Override
        public boolean onScroll(float displacement, float delta, float velocity) {
            // do something on scrolling
        }
    });
    return gestureDetector;
}

/*
 * Send generic motion events to the gesture detector
 */
@Override
public boolean onGenericMotionEvent(MotionEvent event) {
    if (mGestureDetector != null) {
        return mGestureDetector.onMotionEvent(event);
    }
    return false;
}

}

我是这里遗漏了什么还是这是一个bug？

复制和粘贴GDK中的GestureDetector代码并对其进行修改是您需要做的全部工作。如果它的工作为双水龙头，那么我怀疑你可能有一些硬件问题与玻璃

你试过为手势干杯吗？也许敲击和长按是一样的

点击玻璃时，下面的代码将调用generateCard（）

private GestureDetector createGestureDetector(Context context) {
        GestureDetector gestureDetector = new GestureDetector(context);
            //Create a base listener for generic gestures
            gestureDetector.setBaseListener( new GestureDetector.BaseListener() {
                @Override
                public boolean onGesture(Gesture gesture) {
                    if (gesture == Gesture.TAP) { // On Tap, generate a new number
                        generateCard();
                        return true;
                    } else if (gesture == Gesture.TWO_TAP) {
                        // do something on two finger tap
                        return true;
                    } else if (gesture == Gesture.SWIPE_RIGHT) {
                        // do something on right (forward) swipe
                        return true;
                    } else if (gesture == Gesture.SWIPE_LEFT) {
                        // do something on left (backwards) swipe
                        return true;
                    }
                    return false;
                }
            });
            gestureDetector.setFingerListener(new GestureDetector.FingerListener() {
                @Override
                public void onFingerCountChanged(int previousCount, int currentCount) {
                  // do something on finger count changes
                }
            });
            gestureDetector.setScrollListener(new GestureDetector.ScrollListener() {
                @Override
                public boolean onScroll(float displacement, float delta, float velocity) {
                    // do something on scrolling

                    return false;
                }
            });
            return gestureDetector;
        }

        /*
         * Send generic motion events to the gesture detector
         */
        @Override
        public boolean onGenericMotionEvent(MotionEvent event) {
            if (mGestureDetector != null) {
                return mGestureDetector.onMotionEvent(event);
            }
            return false;
        }

我和你有同样的问题，我的答案可能会很奇怪，但我避免使用开关，而不是if-else结构。此外，使用此新代码，您将能够捕获其余手势

我希望它也能帮助你

private GestureDetector createGestureDetector(Context context){
    GestureDetector gestureDetector = new GestureDetector(context);
    //Create a base listener for generic gestures
    gestureDetector.setBaseListener( new GestureDetector.BaseListener() {
        @Override
        public boolean onGesture(Gesture gesture) {
            Log.e(TAG,"gesture = " + gesture);
            switch (gesture) {
                case TAP:
                    Log.e(TAG,"TAP called.");
                    handleGestureTap();
                    break;
                case LONG_PRESS:
                    Log.e(TAG,"LONG_PRESS called.");
                    return true;
                case SWIPE_DOWN:
                    Log.e(TAG,"SWIPE_DOWN called.");
                    return true;
                case SWIPE_LEFT:
                    Log.e(TAG,"SWIPE_LEFT called.");
                    return true;
                case SWIPE_RIGHT:
                    Log.e(TAG,"SWIPE_RIGHT called.");
                    return true;
                case SWIPE_UP:
                    Log.e(TAG,"SWIPE_UP called.");
                    return true;
                case THREE_LONG_PRESS:
                    Log.e(TAG,"THREE_LONG_PRESS called.");
                    return true;
                case THREE_TAP:
                    Log.e(TAG,"THREE_TAP called.");
                    return true;
                case TWO_LONG_PRESS:
                    Log.e(TAG,"TWO_LONG_PRESS called.");
                    return true;
                case TWO_SWIPE_DOWN:
                    Log.e(TAG,"TWO_SWIPE_DOWN called.");
                    return true;
                case TWO_SWIPE_LEFT:
                    Log.e(TAG,"TWO_SWIPE_LEFT called.");
                    return true;
                case TWO_SWIPE_RIGHT:
                    Log.e(TAG,"TWO_SWIPE_RIGHT called.");
                    return true;
                case TWO_SWIPE_UP:
                    Log.e(TAG,"TWO_SWIPE_UP called.");
                    return true;
                case TWO_TAP:
                    Log.e(TAG,"TWO_TAP called.");
                    return true;
            }

            return false;
        }
    });
    gestureDetector.setFingerListener(new com.google.android.glass.touchpad.GestureDetector.FingerListener() {
        @Override
        public void onFingerCountChanged(int previousCount, int currentCount) {
            // do something on finger count changes
            Log.e(TAG,"onFingerCountChanged()");

        }
    });
    gestureDetector.setScrollListener(new com.google.android.glass.touchpad.GestureDetector.ScrollListener() {
        @Override
        public boolean onScroll(float displacement, float delta, float velocity) {
            // do something on scrolling
            Log.e(TAG,"onScroll()");
            return false;
        }
    });
    return gestureDetector;
}

如果您只想捕捉UI的点击事件（不使用GestureDetector和其他工具），则玻璃触控板中的点击会注册为中央点击d-pad，因此您只需截取键盘代码和中央按键即可

试试这个：

public boolean onKeyDown(int keyCode, KeyEvent event) {
    if(keyCode == KeyEvent.KEYCODE_DPAD_CENTER){
        // The touchpad was tapped
        return true;
    }

    return false;
}

当我在触摸板上短暂点击时，您提供的代码会为我打印“点击”。你的意思是，当你做一个快速的瞬间点击，它仍然打印出“长按”？是的。一次又一次地尝试，尽可能快，但从来没有得到一个“水龙头”大概你在玻璃的其他部分没有水龙头行为的问题，那么。出于好奇，你能试一下其他手势，看看它们是否如预期的那样工作吗，比如两次轻拍和三次轻拍，或者一些滑动？是的，两次轻拍和三次轻拍都能正常工作。注意到我点击后有一个延迟，好像它等待的时间与长按的时间相同。有什么更新吗？我也有同样的问题。这肯定是最快最简单的方法。遗憾的是，这个方法不能处理我读过的向左滑动和向右滑动命令，这些命令应该在KeyEvent.isShiftPressed（）上用布尔标志注册在KEYCODE_选项卡下。我想它们只是映射到KEYCODE_DPAD_Left和KEYCODE_DPAD_Right？也许我错了，我也试过了，可惜没用。最后，这是一个没有意义的问题，因为我只是走了手势检测器的路线。
