Question

My Glass已更新至XE16，此后Glassware中使用的Viewpage无法正常工作。通过刷卡无法移动到任何寻呼机。如果以前有人遇到此问题，请提供帮助。

嘿。是的，更新删除了某些标准事物（如触摸板移动焦点上的手势等）。

你要做的是实现一个手势识别器/监听器并实现必要的字段，如下所示（不要忘记在活动中实例化/实现/导入等等））：

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) {
                    // do something on tap
                    //do ?
                    return false;                       
                } else if (gesture == Gesture.TWO_TAP) {
                    // do something on two finger tap
                    return true;
                } else if (gesture == Gesture.LONG_PRESS) {
                    // do something on long press
                    if (!showingMenu)
                    {
                        openOptionsMenu();
                        return true;
                    }
                    else
                    {
                        return false;
                    }
                } else if (gesture == Gesture.SWIPE_RIGHT) {
                    // do something on right (forward) swipe
                    //next slide:
                    mPosition++;
                    if (mPosition >= cardArray.size())
                    {
                        mPosition = cardArray.size() -1;
                    }
                    mGallery.setSelection(mPosition);                       
                    return true;
                } else if (gesture == Gesture.SWIPE_LEFT) {
                    // do something on left (backwards) swipe
                    //previous slide:
                    mPosition--;
                    if (mPosition < 0)
                    {
                        mPosition = 0;
                    }
                    mGallery.setSelection(mPosition);                       
                    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
                if (delta > 5.0f)
                {
                    //scroll forwards:
                    //
                }
                else if (delta < -5.0f)
                {
                    //scroll backwards:
                    //
                }
                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;
}

我用CardScrollView取代了我的Viewpager，它也非常快。试试吧。

XE16更新后，ViewPager无法在Google Glass中运行
