                    // 手指在产生移动的时候（dy!=0）才重置位置
                    if (dy != 0 && isFlow()) {
                        resetPosition();
                        // 把滚动事件交给内部控件处理
                        event.setAction(MotionEvent.ACTION_DOWN);
                        dispatchTouchEvent(event);
                        isInControl = false;
                    }

这里向子View传递事件为什么要修改事件类型呢？
