截獲listview和refreshlayout的dispatchTouchEvent方法，針對不同滑動通知父容器是否通知子控制元件獲取事件

CusMaterialRefreshLayout

float xDown = -1,yDown=-1;
	@Override
	public boolean dispatchTouchEvent(MotionEvent ev) {

		switch (ev.getAction())
		{
			case MotionEvent.ACTION_DOWN:
				xDown = ev.getX();
				yDown = ev.getY();
				getParent().requestDisallowInterceptTouchEvent(true);
				break;
			case MotionEvent.ACTION_MOVE:
				if(Math.abs(ev.getX()-xDown)<Math.abs(ev.getY()-yDown))
				{
					getParent().requestDisallowInterceptTouchEvent(true);
				}else
				{
					getParent().requestDisallowInterceptTouchEvent(false);
				}
				break;
			case MotionEvent.ACTION_CANCEL:
			case MotionEvent.ACTION_UP:
				getParent().requestDisallowInterceptTouchEvent(false);
				break;
		}
		return super.dispatchTouchEvent(ev);
