拦截父控件事件的设置

@Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        //requestDisallowInterceptTouchEvent(disallowIntercept);
        //disallowIntercept=true不让父元素拦截元素;disallowIntercept=false,没有拦截
        getParent().requestDisallowInterceptTouchEvent(true);
        return super.dispatchTouchEvent(ev);
    }
