Question

如何通过侧边栏（在Android市场上）等服务检测滑动事件.... 我尝试布局服务，因此我能够检测滑动手势但主要问题布局视图有自己的区域，因此用服务视图检测滑动事件是个坏主意......

public class GestureSwipe extends Service {

private static final int SWIPE_MIN_DISTANCE =5;
private static final int SWIPE_THRESHOLD_VELOCITY = 10;

@SuppressWarnings("deprecation")
final GestureDetector gt = new GestureDetector(new GestureListener());

private WindowManager wm;
private LinearLayout beam;

@Override
public void onCreate() {
    super.onCreate();
    beam = new LinearLayout(this);
    LayoutParams lp = new LayoutParams(10,LayoutParams.MATCH_PARENT);
    beam.setLayoutParams(lp);
    wm = (WindowManager) getSystemService(WINDOW_SERVICE);
    WindowManager.LayoutParams mParams = new WindowManager.LayoutParams(
            10,WindowManager.LayoutParams.MATCH_PARENT,
            WindowManager.LayoutParams.TYPE_PHONE,
            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
            PixelFormat.TRANSLUCENT);
    mParams.gravity = Gravity.LEFT;
    //beam.setBackgroundColor(Color.RED);
    beam.setOnTouchListener(new OnTouchListener() {
        public boolean onTouch(final View view, final MotionEvent event) {
            gt.onTouchEvent(event);

            return true;
        }
    });
    wm.addView(beam, mParams);
}

@Override
public IBinder onBind(Intent arg0) {
    return null;
}

private class GestureListener extends SimpleOnGestureListener {
    @Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
            float velocityY) {
        if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE
                && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
            return false; // Right to left
        } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE
                && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
            return false; // Left to right
        }
        if (e1.getY() - e2.getY() > SWIPE_MIN_DISTANCE
                && Math.abs(velocityY) > SWIPE_THRESHOLD_VELOCITY) {
            return false; // Bottom to top
        } else if (e2.getY() - e1.getY() > SWIPE_MIN_DISTANCE
                && Math.abs(velocityY) > SWIPE_THRESHOLD_VELOCITY) {

            return false; // Top to bottom
        }
        return false;
    }
  }
}

我的视图是否可能仅检测手势并忽略触摸事件和表现得像其他人的透明触摸...... 请告诉我该怎么做？这样做有什么其他的想法？感谢所有程序员..
