NestedScrollView+tablayout+vierp

解决:在自定义的view中（view继承NestedScrollView）的onInterceptTouchEvent()方法做如下操作

@Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {

        switch (ev.getAction()) {
            case MotionEvent.ACTION_DOWN:
                xDistance = yDistance = 0f;
                xLast = ev.getX();
                yLast = ev.getY();
                break;
            case MotionEvent.ACTION_MOVE:
                final float curX = ev.getX();
                final float curY = ev.getY();

                xDistance += Math.abs(curX - xLast);
                yDistance += Math.abs(curY - yLast);
                xLast = curX;
                yLast = curY;
                Log.e("SiberiaDante", "xDistance ：" + xDistance + "---yDistance:" + yDistance);
                if (isNeedScroll) {
                    if (xDistance == yDistance) {//点击不拦截
                        return false;
                    }
                    if (xDistance>yDistance){//左右滑动不拦截
                        return false;
                    }
                    if (xDistance<yDistance){//上下滑动拦截
                        return true;
                    }
                }else{
                    return false;
                }
//                return !(xDistance > yDistance || yDistance < scaledTouchSlop) && isNeedScroll;

        }

        return super.onInterceptTouchEvent(ev);
    }
