android - 带有OnItemClickListener和GestureDetector的Android ListView

我有以下列表活动：

public class ShowDayActivity extends ListActivity implements OnItemClickListener {
    private GestureDetector gestureDetector;
    private View.OnTouchListener gestureListener;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.day);
        registerForContextMenu(getListView());

        gestureDetector = new GestureDetector(new MyGestureDetector());
        gestureListener = new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                return gestureDetector.onTouchEvent(event);
            }
        };

        getListView().setOnItemClickListener(this);
        getListView().setOnTouchListener(gestureListener);
    }

    @SuppressWarnings("static-access")
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        ...
        return super.onOptionsItemSelected(item);
    }

    @Override
    public boolean onContextItemSelected(MenuItem item) {
        ...
        return super.onContextItemSelected(item);
    }

    Override
    public void onItemClick(AdapterView<?> parent, View v, int pos, long id) {
        editEvent(pos);
    }

    class MyGestureDetector extends SimpleOnGestureListener {
        private static final int SWIPE_MIN_DISTANCE = 120;
        private static final int SWIPE_MAX_OFF_PATH = 250;
        private static final int SWIPE_THRESHOLD_VELOCITY = 200;

        @Override
        public boolean onFling(MotionEvent e1, MotionEvent e2,
                               float velocityX, float velocityY) {
            if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH) {
               return false;
            }
            // right to left swipe
            if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
                Log.d("ICS-Calendar", "Fling left");
                return true;
            } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
                Log.d("ICS-Calendar", "Fling right");
                return true;
            }

            return false;
        }
    }
}

列表项上的ContextListener（长单击）工作得很好。今天我添加了GestureListener和Detector，它也可以工作，但是：
GestureDetector可以检测到一个fling，但是在完成逻辑之后，上下文菜单就会打开，这显然不是我想要的。你知道我做错了什么吗？或者我该怎么办？

最佳答案

通常，在检测到onfling之后，需要为视图及其所有子视图调用cancellongpress（）方法。但是对于AbslistView，此方法不执行任何操作：（
但我找到了解决方法：在onfling回调函数中，处理完所有事情后，对listview对象执行下一步：

Event cancelEvent = Event.obtain(ev2);
cancelEvent.setAction(MotionEvent.ACTION_UP);
listView.onTouchEvent(cancelEvent);
