listView下拉刷新时，为什么同时触发点击事件，如何让下拉时不触发点击事件

Question

/**
* Touch事件
*/
@Override
public boolean onTouchEvent(MotionEvent ev) {
Log.e("666","555");

    switch (ev.getAction()) {
        case MotionEvent.ACTION_DOWN:
            //按下时Y坐标
            // 正在刷新不能移动
            if (currentState == REFRESH) {
                return  true;
            }
                downY = (int) ev.getY();
            Log.e("55555666","555");
            break;
        case MotionEvent.ACTION_MOVE:

            int deltaY = (int) (ev.getY() - downY);

            if(deltaY>0){
                footerView.setPadding(0, -footerViewHeight, 0, 0);
            }

            int paddingTop = -headerViewHeight + deltaY;

            if (paddingTop > -headerViewHeight
                    && getFirstVisiblePosition() == 0) {
                headerView.setPadding(0, paddingTop, 0, 0);

                if (paddingTop > 0 && currentState == PULL) {   //currentState当前状态下拉刷新状态
                    // 进入松开刷新状态
                    currentState = RELEASE;// RELEASE松开刷新状态
                    refreshHeaderView();

                } else if (paddingTop <= 0 && currentState == RELEASE) {
                    // 进入刷新状态
                    currentState = PULL;
                    refreshHeaderView();
                }

                return true;// 拦截TouchMove，不让listView处理该次move事件;会造成listView无法滑动
            }
            break;

        case MotionEvent.ACTION_UP:
            if (currentState == PULL) {
                headerView.setPadding(0, -headerViewHeight, 0, 0);
            } else if (currentState == RELEASE) {
                headerView.setPadding(0, 0, 0, 0);
                currentState = REFRESH;
                refreshHeaderView();
                if (listener != null) {
                    listener.onPullrefresh();
                }

            }

            break;
        default:
            break;
    }
    isRecored =true;
    return super.onTouchEvent(ev);

}
