Google眼镜：借助swipe_left和swipe_right上下滚动

Question

有没有办法，我能胜任向上滚动，并在我的活动下来感谢对Gesture.SWIPE_RIGHT（这将触发向上滚动操作）和Gesture.SWIPE_LEFT（这将触发向下滚动操作）的方法吗？

任何代码都将不胜感激...

以下代码基本上是复制自官方指南的代码 。 定义scrollUp和scrollDown ，你想方法。

public class MyActivity extends Activity {
  private GestureDetector mGestureDetector;

  @Override
  public void onCreate(Bundle savedInstanceState) {
    ...
    mGestureDetector = createGestureDetector();
  }

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

  private GestureDetector createGestureDetector() {
    GestureDetector gestureDetector = new GestureDetector(this);
    gestureDetector.setBaseListener(new GestureDetector.BaseListener() {
      @Override
      public boolean onGesture(Gesture gesture) {
        if (gesture == Gesture.SWIPE_RIGHT) {
          scrollUp();
          return true;
        } else if (gesture == Gesture.SWIPE_LEFT) {
          scrollDown();
          return true;
        }
        return false;
      }
    }

    return gestureDetector;
  }

}
