android - 如何防止 ListView 在触摸/滑动/甩动它的行时滚动？

Question

如果在某些特定 ListView 的行中做出这些手势，我需要停止 ListView 以响应用户手势 - 如何做到这一点？目标 ListView 的行 View 设置了 onTouchListener，由于 ListView 向上/向下滚动，我无法识别滑动/翻转。因此，如果我向上或向下移动手指 - ListView 会拦截它并向相应的方向滚动。所以我需要以某种方式来规则它，就像 Y 坐标变化超过一定数量一样 - 让 ListView 滚动，如果没有 - 将手势识别为快速/滑动。 OnTouchListener 是

private int SWIPE_MIN_DISTANCE = 1;
private int SWIPE_MAX_OFF_PATH = 300;

final OnTouchListener flingSwipeListener =  new OnTouchListener() {
    float touchX;
    float touchY;
    @Override
    public boolean onTouch(final View view, final MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN)
        {
            touchX = event.getX();
            touchY = event.getY();
        }
        else if (event.getAction() == MotionEvent.ACTION_UP)
        {                   
        if (Math.abs(touchY - event.getY()) > SWIPE_MAX_OFF_PATH)
                    return false;
            // right to left swipe
            else if (touchX - event.getX() > SWIPE_MIN_DISTANCE){
                    Log.i("flingSwipe","right to left swipe");
            } 
            // left to right swipe
            else if (event.getX() - touchX > SWIPE_MIN_DISTANCE){
                    Log.i("flingSwipe","left to right swipe");
            }
        }
        return true;

    }
};

这个 onTouchListner 被设置为一个特定的行。我需要在 onTouchListener 识别手势时卡住 ListView，但如果它失败，我需要将 MotionEvent 发送到 ListView。

如果您需要在特定行上禁用触摸监听器。比这简单。

在所需的列表行上设置标签。在 getview 列表适配器类中。

例如:

ABCList extends ArrayAdapter<String> {
        public MyCustomAdapter(Context context, int textViewResourceId,
                String[] objects) {
            super(context, textViewResourceId, objects);
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {

            View row = inflater.inflate(R.layout.history_list_item, parent,
                    false);

            if(position == YOUR_DESIRED_ROW)
                          row.setTag("disableThisRow")

            return row;
        }


    }

然后像这样编辑触摸监听器。

 final OnTouchListener flingSwipeListener =  new OnTouchListener() {
    float touchX;
    float touchY;
    @Override
    public boolean onTouch(final View view, final MotionEvent event) {
       String isRow=view.getTag();
       if(isRow.equals("disableThisRow"))return false;

        if (event.getAction() == MotionEvent.ACTION_DOWN)
        {
            touchX = event.getX();
            touchY = event.getY();
        }
        else if (event.getAction() == MotionEvent.ACTION_UP)
        {                   
        if (Math.abs(touchY - event.getY()) > SWIPE_MAX_OFF_PATH)
                    return false;
            // right to left swipe
            else if (touchX - event.getX() > SWIPE_MIN_DISTANCE){
                    Log.i("flingSwipe","right to left swipe");
            } 
            // left to right swipe
            else if (event.getX() - touchX > SWIPE_MIN_DISTANCE){
                    Log.i("flingSwipe","left to right swipe");
            }
        }

        return true;

    }
};

这将禁用禁用列表项的触摸..希望这有帮助。或者如果你有更多的手势听众，那也将与此类似。希望对你有帮助
