我有以下ListActivity：

I have a the following ListActivity:

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;
        }
    }   
} 

在listItems中的contextListener（长按）完美的作品。今天，我加入了gestureListener和检测器，它的工作原理也一样，但是：

The contextListener (long-click) on the listItems works perfectly. Today i added the gestureListener and Detector, which works too, BUT:

该GestureDetector检测一扔所有的权利，但在它与它的逻辑做的，上下文菜单打开，这显然不是我想要的。任何想法，我做错了，或者我可以做什么呢？

The GestureDetector detects a fling all right, but after it's done with its logic, the context menu opens, which is obviously not what i want. Any ideas what i'm doing wrong, or what i might do about it?

推荐答案

通常情况下，你需要调用的 cancelLong preSS（）的方法查看毕竟视图的孩子的 onFling 的已被检测到。但对于 AbsListView 的这个方法做什么：（

Normally, you need to call cancelLongPress() method for view and all view's children after onFling has been detected. But for AbsListView this method do nothing :(

不过，我已经找到解决方法是：在 onFling 的回调，毕竟事情进行了处理，做下为您的的ListView 的对象：

But I've found workaround for it: in the onFling callback, after all things were processed, do the next for your ListView object:

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