我有一个类似 gridview 的日历，带有手势和 OnItemClickListener 。当用户从左向右滑动时， GridView 将显示下个月。当用户从右向左滑动 GridView 时，它会显示上个月。我对这些事件使用 SimpleOnGestureListener。当我点击 gridview 的项目时，我想显示当前项目的详细信息。问题是当我只执行其中一个事件(Gesture 和 OnItemClickListener)时，它们工作正常。但是当我同时执行这两项操作时，手势工作正常并且 OnItemClickListener 没有获得点击 View ，它总是获得被点击项目行的第一个 View 。请帮帮我 。对不起，如果我的问题打扰了你，另外为我糟糕的英语道歉。谢谢。

这是我用来检测手势的代码:

     public class GestureListener extends SimpleOnGestureListener {

    private static final int SWIPE_THRESHOLD = 100;
    private static final int SWIPE_VELOCITY_THRESHOLD = 200;
  /*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 onDown(MotionEvent e) {
        return true;
    }

    @Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
        boolean result = false;
        try {
            float diffY = e2.getY() - e1.getY();
            float diffX = e2.getX() - e1.getX();
            if (Math.abs(diffX) > Math.abs(diffY)) {
                if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
                    if (diffX > 0) {
                        onSwipeRight();
                    } else {
                        onSwipeLeft();
                    }
                }
            } else {
                if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
                    if (diffY > 0) {
                        onSwipeBottom();
                    } else {
                        onSwipeTop();
                    }
                }
            }
        } catch (Exception exception) {
            exception.printStackTrace();
        }
        return result;
    }

    @Override
    public boolean onSingleTapUp(MotionEvent e) {
        // TODO Auto-generated method stub
        Log.i("single", "singletaps");
        return super.onSingleTapUp(e);
    }


}

public void onSingleTap(View v){

}
public void onSwipeRight() {
}

public void onSwipeLeft() {
}

public void onSwipeTop() {
}

public void onSwipeBottom() {
}

这是 onItemClickListener 的代码

gridview.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v,
                int position, long id) {

            ((CalendarAdapter) parent.getAdapter()).setSelected(v);
            String selectedGridDate = CalendarAdapter.dayString
                    .get(position);
            String[] separatedTime = selectedGridDate.split("-");
            String gridvalueString = separatedTime[2].replaceFirst("^0*",
                    "");// taking last part of date. ie; 2 from 2012-12-02.
            int gridvalue = Integer.parseInt(gridvalueString);
            // navigate to next or previous month on clicking offdays.
            if ((gridvalue > 10) && (position < 8)) {
                setPreviousMonth();
                refreshCalendar();
            } else if ((gridvalue < 7) && (position > 28)) {
                setNextMonth();
                refreshCalendar();
            }
            ((CalendarAdapter) parent.getAdapter()).setSelected(v);

        }
    });

最佳答案

我也有同样的问题。在 onDown 方法中返回 false 对我有帮助:

@Override
public boolean onDown(MotionEvent e) {
    return false;
}
